英文摘要：
Based on the reliability-based design theory of mechanical system and sensitivity analysis method,the reliability-based sensitivity analysis of mechanical system with correlated failure modes under incomplete probability information is extensively researched and a numerical method for reliability-based sensitivity analysis is presented.The variation regularities of reliability sensitivity are obtained and the effects of design parameters on reliability of mechanical system are studied,and the theoretic basis for the reliability-based design of mechanical system is obtained.
