摘要
可靠性灵敏度分析在可靠性设计和修改、可靠性优化设计、可靠性维护等方面均有重要的应用。该文讨论了后桥的可靠性参数灵敏度分析问题 ,提出了可靠性灵敏度设计的计算方法 ,研究了正态分布设计参数的改变对后桥可靠性的影响 ,为后桥的可靠性设计提供了理论依据。
A useful sensitivity analysis of reliability has practical applications in reliability based design, in optimization of vehicle design, construction, maintenance and inspection under reliability constraints, in parameter studies of the reliability, and in reliability updating. The parametric sensitivity in reliability of the rear axle casing is extensively discussed and a numerical method for reliability sensitivity analysis is presented. The effects of normally distributed design parameters on reliability of the rear axle casing are studied. The method presented in this paper provided the theoretic basis for the reliability design of the rear axle casing.
