摘　　要：讨论了圆锥齿轮可靠性灵敏度的计算和分析问题,提出了可靠性灵敏度分析的计算方法;研究了正态分布参数的改变对圆锥齿轮可靠性的影响,编制了实用的计算机程序,利用它可以迅速准确地得到汽车零部件可靠性灵敏度的设计信息,为汽车零部件的可靠性设计提供了理论依据。The reliability-based sensitivity computation and analysis of bevel gears was extensively discussed and a numerical method for reliability sensitivity computation and analysis was presented. The effect of basic normal distribution parameters on reliability of the bevel gears was studied. The respective programs can be used to obtain the reliability-based sensitivity information of the bevel gears accurately and quickly. The method presented herein provides the theoretical basis for relia bility design of the bevel gears.
