Applied Program: Mechanical Engineering
In China there is an old custom called one-year anniversary fortune-telling: by the time the new born is one year old, its family prepares a lot of objects of different shapes and functions for it to choose from. The first object that attracts its eyes and hands is supposed to be a symbol of the baby’s future career. Unscientific as it is, it truly predicted my profession and future. At that time the toy car in my hand greatly aroused my wonder at the wheeled monster. As I grew up, I was no longer satisfied with collecting car pictures and making car models. I was determined to be an expert in automobile design and manufacturing. As it turned out, the specialized education I have received in both my undergraduate and graduate programs have fully equipped me for undertaking more ambitious academic tasks in the field of mechanical control.
I know I am no genius and I also know that success is to result from extraordinary efforts. I chose as my starting point Beijing Institute of Technology, one of the 3 universities in China that majored in automobile research. There besides the specialty and theory studies, I made use of my free time to read large quantities of references both in Chinese and English, to catch up with the latest development in theory and to be immersed in the widest range of information. As a graduate, my academic performance had always ranked No.1 in my class, especially for the 20 also specialty courses in the junior and senior years, among which Automotive Manufacturing got full scores. For 4 years I got the first or the second class scholarships consecutively and was awarded many honors such as Outstanding Student, Outstanding Cadre, as well as appraised by the department leader as the best student in the recent 5 years.
The strong interests in automobile forever stimulated my enthusiasm in study and motivated me to equip myself with specialty knowledge to the greatest possible extent. Apart from the study task, I also served as teaching assistant in the course of vehicle electronic technology. As a post graduate and with the specialty knowledge getting more and more profound, I worked as a research assistant in the laboratory and came to better my ability to apply theory into practice, thus capable of carrying out scientific research activities independently. Meanwhile I took part in many research and development projects and accumulated rich experiences on that. In the joint-venture project between our school and the first automobile manufacturing plant in China, I was responsible for building up experimental framework composed of the electric motor, hydrostatic gearbox, loading device and the control system and carried out the functional adjusting of the automatic shift, thus getting a better knowledge of the power train. The experiment was a great success and provided reliable support for the overall vehicle experiment.
The thesis for my master degree is Research of Loader with Automatic Shift Technology and Fuzzy Control Strategy. At present, China’s research on automation of construction machinery has not started yet. I choose this subject in order to realize automatic shift control and computerization of construction machinery. It is mainly concerned with coordination control of the engine and the gearbox, power distribution, recognition and fuzzy control of the working state of construction machinery and so on. This is based on the joint venture----the automatic shift control of ZL50 loader between our school and a gearbox manufacturing plant in Hunan. The purpose of this research project is to change the loader’s original manual shift into automatic shift control. The stumbling blocks here are the recognition of different working states, the coordination of the engine and the gearbox and the realization of the potential engine power to the greatest possible extent.
In that project I was responsible for the whole process from the project demonstration, program selection, simulation research and project implementation. We largely enhanced the automation level and working efficiency of ZL50 loader and made convenient its operation. At the same time I benefited a lot from a deeper understanding of the essence of automatic shift techniques. Apart from the completion of my graduation thesis and based on the experimental statistics and the project’s early stage work summary, I published, on the national central periodical named Construction Machinery, a paper titled Research on the Mechanical Parts of Electronically Controlled Automatic Shift on ZL50 Loader and also another paper, on Construction Machinery and Equipment, titled Research of ZL50 Loader with Electronic Controlled Automatic Shift System, which has the project outcome as its theoretic basis. They were highly praised by experts in this field for their values in academic research and of creativity. Because of the need to collect large quantities of experimental data for possible future renovation reference, I independently developed a set of data collecting soft ware, with the transmitter soft ware written in C language and the receiver soft ware written in VC++, communication between the two through series connections. This soft ware was highly usable throughout the whole experiment and greatly increased my work efficiency.
Automobile industry is the main industry for a country. It started very late in China and lags far behind the advanced countries such as the United States, Germany, Canada and others, its competency comparatively low. To shorten the distance, it is necessary to go abroad and learn from the developed countries the advanced automobile manufacturing technology and for that reason it is also urgent to perfect my knowledge structure and enhance my specialty level. The specialty of mechanical engineering in University of Michigan ranked No. 11 in the United States. It has rich technical resources and its research centers and laboratories are proud of state-of-the-art equipments. The research work of Vehicle Power train Dynamics and Control being carried out there by many famous professors well fits into my postgraduate research work. So I wish to continue my education in your university. A scrutiny of my educational background and of the research projects that I have performed will indicate that I have a solid foundation in mechanical control. Therefore, my knowledge and specialized trainings in mechanical control will also enable me to prove competent in control-related programs. If my qualifications suit me also for a program in mechanical control, do not hesitate to transfer me to such program because I am equally interested in those programs. My study plan is to learn the fundamental knowledge first and then, based on my own research background, decide on a research direction that will best facilitate the development of China’s automobile industry. In this way I will try to work out valuable academic achievements and write high-level doctorate thesis. Eventually I will return to China to contribute my learning to the development of automobile industry in my fatherland and thus realize the dreams of my childhood

The heights by great men reached and kept, were not attained by sudden flight, but they, while their companions slept, were toiling upward in the night.
--My Motto
While I was still as freshman in 1991, I took part in a project in which a milling machine design done by Germans with CAD technology twenty years before was closely duplicated. Staring at the German blueprints, I was struck dumbfounded by the technological gap between the world's leading industrial countries and my motherland. That experience has been goading me to delve deeper and deeper into research of Mechanical Engineering ever since. I felt then that it was my responsibility to help close the gap. Over seven years has passed, and I am glad to say that I have done my share to my country's technological progress in my field. But to actually help put my country at a technological par with that of the West, I must receiver advanced education in a Western university. For that, I am now applying for Ph. D. studies in your distinguished program.
On the strength of my performance in the National University Entrance Examinations, I gained acceptance in 1990 into the Department of Mechanical Engineering at Huadong Institute of Technology (HDIT), a significant cradle of engineering talents based in Shanghai, the country's economic capital. But I did not confine myself to taking courses in my department. In order to satisfy my curiosity in modern science and science and enrich my knowledge, I learned not only the fundamentals of Mechanical Science such as mechanics, metals, process and materials, but also some other courses like Discrete Mathematics. Advanced Algebra, Group Theory etc by auditing them in other departments. My overall GPA was consistently among the top 5% and I received consecutive scholarships for all four years, including Excellent Undergraduate Scholarship of HDIT, the highest honor conferred only to the most distinguished and promising student in an overall evaluation.
Shortly after my enrollment at ZJU, I was assigned as a research assistant to Professor XXX, Vice President of ZJU in the university's CAD Center. Because of my apparent academic strengths, I was encouraged to independently engage in solving the two-dimension irregular shape layout problem in terms of the application of mathematical model of optimization. Through nearly one year hardworking, I came up with three kinds of two-phase heuristic algorithms and a new geometrically-based algorithm.
In October, 1995, our research team began to take part in a project Integrated CAD/CAM System for Sheet Metal, part of the country's strategic high-tech development program, dubbed the 863 Program. I first developed the Flat Parts Layout Tool on the basis of my layout algorithms. I then developed a 3D Parts Unfolding Tool, which can convert the part initial 3-D model to 2-D pattern automatically by focusing on the research of anti-process of unfolding: bending process and creating a library of parametric typical shapes. Finally, we developed a software package Inte-SheetMetal, using AutoCAD as the graphic interface and C++ as the main programming language.
While I was doing the above project, I finished my Master's thesis: "Research and Implementation of Sheet Metal Part Unfolding and Optimal Layout", which proposed a new approach of obtaining 2-D pattern from 3-D design model and generating certain layout schemes for process planning and manufacturing.
Since my graduation in July1997, I have been working as a Research Engineer by the Engineering Design Research Laboratory, CERIS. The primary goal of research conducted in this lab is to develop Engineering Design methodologies and techniques to permit rapid, accurate, conservative design and fabrication of present-day mechanical products.
As a member of the lab's staff, I have participated in the GaoHua-601 Project, a large project supported by the China National Ministry of Machine Building Industry. Its goal is to develop many rapid-prototyping systems that will produce prototype parts from concept models as soon as possible. Perhaps because I was familiar with the fatal drawback of conventional CAD/CAM systems, I witched my interest to emphasizing "How to improve the information exchange between design and manufacturing processes?" and thus chose the subproject: "Feature Based Technology in Injection Molding Design."
Based on the RPDS (Rapid Product Design System ) other researchers have developed within the Pro/Engineer software environment, I modified the basic data structure of part model and proposed a novel Unified Structure Model (USM). Characterized by its geometric feature parameters and non-geometric feature parameters such as material, process etc., this model provides an efficient framework to maintain the whole product development process. Currently, I am developing a special feature "Definition & Recognition" based on the USM with the help of two members of our research team. In general, I have been developing most of the core models and responsible for integrating all the models into a prototype system. Through these experiences, I have learned the most valuable lessons in my study and work: diligence, team spirit and creativity are the three necessities for successful research work, and I am now confident that I can embark on research work in a new field.
As the world awaits the onset of the 21st century, mechanical engineering is playing an ever-increasing role in serving global needs. As mechanical engineers, we should be able to conceive, plan, design, and direct the manufacture, distribution, and operation of a wide variety of devices, machines and systems for energy conversion, aerospace applications, environmental control, and many other applications. In doing all or any of this, we are necessarily involved in computer-aided design and manufacturing, product development, theoretical and applied research.
The Mechanical Engineering Department of University of XXX, known for its meticulous work ethics and stimulating academic atmosphere, is the place I have long admired. I am sure that my enterprising spirit, under the seasoned guidance of your distinguished faculty, will translate into knowledge and expertise beneficial to both United States and China.
My degree objective is Ph. D, and my major academic interest lies in the following areas: 1) CAD/CAM/CAPP, 2) Computer Graphics & Simulation, 3) Feature-based Design, 4) Design Optimization, 5) Sheet Metal Production, 6) Die and mould Design & Manufacturing. There are several reasons I am confident that I can do well in the courses and research work relating to these areas. Firstly, I have been involved in Mechanical Engineering for about eight years and gained a lot of tremendous experiences in such diverse such as automation and computer. Furthermore, through the "work and study" experiences, I have accumulated lots of practical and theoretical knowledge, not only from books but also from actual work in my interested fields. Finally, I know that I am a quicker learner, and I tend to assimilate new materials in relative ease and speed. This will equip me well to meet the rigorous academic challenge posed in your curriculum.
If I am lucky enough to be admitted and financially supported by your esteemed university, I would like to spend three to four years pursuing my Ph.D. in the above areas. After completion of the studies, I will return to my motherland and contribute my learning to improving my country's mechanical industry.

Having undertaken an undergraduate program at the Department of Automobile Engineering of XX University, I have evolved an in-depth understanding of mechanical engineering. Considering myself well-equipped for a Ph.D. program in Mechanical Engineering, I hereby file this application for your earnest review.
My application for your Ph. D. program is most directly motivated by The 3rd ASEE International Colloquium on Engineering Education held from Sept. 7 to 10 at XX University. “China will be a major manufacturing power in the world in the near future and China will need a large number of mechanical engineers for that purpose,” XX chairman explained why the organization chose China as the first developing country to hold the Colloquium. While a growing number of engineering students in China choose to shift to IT industry, I choose to stick to the discipline I am studying because it has been and will continue to be the most fundamental field in this technology-dominated world.
Most prestigious for its education and research in engineering, XX University has offered me the most comprehensive and systematic training that an engineering student can expect. In undertaking my specialized automobile engineering program, I have carried out, apart from the required coursework in English language, advanced mathematics and physics, in-depth study of the specialized courses, especially those related to mechanics such as engineering mechanics, fluid mechanics, and materials mechanics. Learning those courses has helped me acquire the fundamental knowledge and skills in analyzing and solving problems in mechanics. They have proved particularly important in view of the research work I participated in in the second half of my undergraduate program. My experience is that although we can resort to software systems like ANSYS to perform relevant computations, the knowledge in basic mechanics remains fundamental to the formation of effective design concepts.
Of course, I have done intensive coursework on automobile composition, automobile assembly and dismantling, fundamentals of automobile engineering, man-machine engineering, together with a host of engineering-oriented courses. My overall understanding of engineering was further enhanced，no longer remaining on the superficial level of automobile styling but concerned with the central theories and structural designs. Like all engineering students, I have been inevitably exposed to another category of courses that required much practice and hands-on applications such as model production, physical experiments, and quality engineering.
The process of learning has also been a process of discoveries. With increasing interest in automobile impact and safety, I have joined the Impact Laboratory headed by Prof. XX since the first semester of my junior year. Lab experiments have since become another channel to exploit my potential and to improve my practical problem-solving abilities. When studying the lift and drag coefficients of the plates in the fixed fluid field under different circumstances, I made special efforts to teach myself the Fluent software, which allowed me to simulate the numerical results through computer-aided modeling, an achievement duly recognized by Prof. XX.
My outstanding performance and demonstrated skills qualified me as research assistant of the lab in another project—XX. The device is used to conduct damage experiments on certain automobile parts like beam in order to obtain test statistics concerning the materials and structure. In order to rationalize my design, I self-studied the course Finite Element to verify the bearing capacity of various supporting structures. In addition, I designed release, direction guidance and safety devices. Together with experienced engineers, we often discussed structural, processing and implementation feasibilities. In designing the release structure, I discarded the conventional design and developed a purely mechanical structure which significantly reduced the equipment cost but reached the same experimental requirements.
Satisfied with my performance, Prof. XX has arranged for me to undertake my graduation project in the same laboratory. My project focuses on the theoretical verification and the design of XX. The problem I face is how to control, based on the dropping test device, the continuous collision experiments during the dropping’s tiny time intervals so as to obtain statistics of the test specimens in the state of continuous replenishment of collision energy.
As a matter of fact, similar equipment can be found in XX. Named XX，the expensive equipment costs about 500, 000 US dollars and is electrically controlled. The mechanically controlled device that I am to design, though maybe inferior to XX in precision, will still satisfy experiment requirements and be greatly reduced in cost (less than 10000 US dollars). If realized, my design will constitute a pioneering research in the field and Prof. XX has once again expressed his appreciation of my original and creative conceptualization. My research experience may also include participating in the near future in the experiment of finite element analysis about bone fracture, which falls under biomechanics. Because of the lack of technologies, no experiments in this field have been performed in this respect, even though the research itself is of crucial significance to the safety of automobile passengers.
Off campus, I have sought opportunities for practice. I did a production internship last year at XX Vehicles Manufacturing Base where I studied the processing of engineer parts. Currently, I am working part-time as assistant manager at the Marketing Department of XX Co. Ltd. Those experiences have not only strengthened my teamwork at workplace but also exposed to the realities of part of the automobile industry.
Through all my academic, research and internship experiences, I have come to develop a clear picture concerning my future research interests. In my proposed program in Mechanical Engineering, I expect to research on engineering mechanics, solid mechanics, fluid mechanics, and computational mechanics. Part of the research will be very much an extension of what I have been doing in my lab so far. The research also involves the application of mechanics knowledge and large-scale computer software to simulate the mechanical properties of various materials and structures. As I am proficient in major engineering software ranging from ALAIS, ANSYS, CATA to FLUENT, I can perform simulation and research once I join any research projects.
University of XX is most reputed for its mechanical engineering. Its respected faculty are making breakthroughs in developing the next generation of education approaches needed to impart interdisciplinary thinking and hands-on experiences in an asynchronous, web-based format. Research fields under your program range from well-known fields such as automotive engineering to micro and nano systems, eco-design and manufacturing, and biosystems. A careful study of the research performed by your faculty reinforces my determination to apply for your Department. Prof. XX specializes in fluid mechanics; nanoscale biofluidics and biologically inspired systems; Brownian dynamics simulations; parallel computing. Prof. XX specializes in biomechanics while Prof. XX may teach me about advanced manufacturing and materials processing. Any one of them can be identified as my prospective advisor from whom I can learn advanced knowledge and develop professional expertise required to become a well-trained mechanical engineer.
It is regrettable that, for all the research and practice I have done, I have failed to develop my research findings into research papers. Nevertheless, with my unbounded research potential and under the productive guidance of my prospective advisor, the publication of research papers will only be a matter of time. A person with many creative ideas, I look forward to embarking on your program which promises to let me transform these ideas into reality. I am further convinced that your Ph. D. program will develop me into a leading mechanical engineer in a country which is so sorely in need of such engineers.

Mechanical engineering is the foundation of industry. It plays a key role in the national economy. It’s broad field including general engineering, aeronautical, chemical and nuclear engineering, etc. Provides a sufficient room of choices for me to realize the dream of becoming a scientist or a mechanical engineer. It was with this fact in mind that I decided to choose mechanical engineering as the major field of study for both undergraduate and graduate career at Tsinghua University.
During nearly eight years of study at Tsinghua University, I completed a total of 47 courses in undergraduate study, 14 courses in graduate study. The major courses that interested me most included: Theoretical Mechanics, Strength of Materials, Elasticity and Plasticity Mechanical Analysis of Plastic Deformation Processes, Theory of Metal Forming, Computer Language and Programming, Mechanical Design, etc… After graduation, I entered the First Heaby Machinery Works (in northeast of China). During this period, I became familiar with the design and manufacturing of some heavy machines, thus furthering my interest in mechanical engineering. At the same time, I found that many good ideas of design could not be put into existence because of the backwardness in raw material quality and processing techniques. This fact impelled the related areas and me to concentrate my research interest on materials science and processing. Through careful survey, I selected a subject about the quality control of heavy disc forging and took it as my research subject for master degree. After over tow years of investigation, I finally made a great innovation in the forging process, making the end product rate increase from 50% to 90%. In the course of investigation and my later working after graduate study, I also found some problems that are common in mechanical industry. For example, how do cracks in products during hot metal working generate and develop? How to avoid cracks? How do non-metallic inclusions affect the properties of materials? How to control the content, shape and distribution of inclusions in final products? Solution to these problems will improve the quality of many kinds of products. But they are often difficult to be solved because they include knowledge of many disciplines and require many new research methods. I feel that what I have learned is far from sufficient to tackle all the problems. Thus I have decided to continue my education by pursuing a doctoral degree in mechanical engineering in a highly industrialized country like the United States.
I plan to complete my degree objective I 3 to 5 year and hope that I will be able to further my knowledge I areas including Solid Mechanics, Materials Science and Processes, CAD/CAM, etc… After completing my graduate study, I will return to contribute my learning to my country. I plan to work as a researcher of a teacher at an institute or a university.
