Summary :Entrusted by Zhao Qing Hongteo Die Casting Company ltd ,
From May 8, 20## to May 10,2006 .in the Applied Mechanics and Engineering Lab Center of  Zhong Shang University . Static Load Stress Test was performed on the parts  with the numbers of NJMZ03―1、NJMZ03―2、NJMZ03―3、NJMZ03―4、NJMZ04―1、NJMZ04―2 & NJMZ04―3 .Therein the maximum destroy load was 25.9kN,the minimum destroy load was 25.2kN.Cracks occurred on the sides of all the M10×1.25 threaded holes of tested parts .The cause for destroy was the stress concentration caused by the threaded holes ,resulting in weakness of strength in that area It is suggested to enhance the strength of that area,so as to improve the ability to withstand static load stress.

摘要: 受肇庆鸿特精密压铸有限公司委托, 20##年5月8日至10日在中山大学工程力学实验中心对编号为NJMZ03―1、NJMZ03―2、NJMZ03―3、NJMZ03―4、NJMZ04―1、NJMZ04―2和NJMZ04―3产品进行了静载压力试验。其中最大破坏荷载为25.9 kN，最小破坏荷载为25.2 kN。各个试件都在M10×1.25螺纹孔边发生开裂。破坏的原因是螺纹孔引起应力集中, 导致此处的强度较薄弱。建议增加此处的强度, 使产品承受静载压力的能力得以提高。

一 Test device

The Static Load Stress Test on part NJMZ03 and NJMZ04  was performed in a the all –powerful material tester. The tested part was mounted on the in-house designed racks .The device is shown in picture 1.

一   试验装置

NJMZ03和NJMZ04产品的静载压力试验在万能材料试验机WES-1000上进行，试件安装在自行设计的支座上, 装置如图1所示。

Destroy load value from the test is rather centralized ,dispersivity is slight

试验所得的破坏荷载数值比较集中, 离散性较小。
