摘　　要：讨论了钢板弹簧的可靠性分析的参数灵敏度问题,提出了可靠性灵敏度分析的计算方法,研究了正态分布设计参数的改变对钢板弹簧可靠性的影响,为钢板弹簧的可靠性设计提供了理论依据。The parametric sensitivity in reliability analysis of a multi-leaf spring is extensively discussed and a calculation method for reliability sensitivity analysis is presented. The effects of changes in a normally distributed design parameters on reliability of the multi-leaf spring are studied. The method presented here provides a theoretical basis for its reliability design.

关 键 词：钢板弹簧 可靠性设计 灵敏度
