| 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. |
