| 摘 要： | 膜片组件是影响某伺服系统贮存可靠性的关键部组件,在分析膜片组件在库房贮存条件下失效机理的基础上,通过有限元建模分析,预测了膜片组件的贮存主要失效模式。研究设计了膜片组件恒定温度应力加速贮存试验方案并实施试验,对膜片组件加速贮存试验获得的区间数据进行了插值处理,并对处理后的试验数据进行统计分析,得到了贮存条件下膜片组件的贮存期评估结论。

| Abstract: | Diaphragm assembly is a critical component influencing storage reliability of servo system.Based on analysis of depot storage environment and the failure mechanism of diaphragm assembly,main storage failure modes of diaphragm assembly were predicted though finite element analysis.An accelerated storage test for the diaphragm assembly was designed and carried out.Linear interpolation algorithms were used to process the data obtained from the accelerated test of the diaphragm assembly.Through statistic analyzing of the processed data,the storage life of the diaphragm assembly under storage environment was evaluated. |

| Keywords: | diaphragm assembly failure analysis accelerated storage test constant stress statistic analysis |
