轴的多失效模式相关的可靠性计算

Reliability Calculation for Multi-failure Mode of Shaft Design

介绍了 3种类型的轴的 4种基本失效模式 ,给出了多失效模式相关时的机械可靠性分析方法。利用功能函数方程 ,根据O .Ditlevsen理论给出了在失效模式相关时的相关系数和可靠度的计算公式。

This paper introduces the four basic failure modes of three types of shaft, and explicates the multi-failure mode related mechanical reliability analysis approach. By using functional function equation, the computing formula of failure mode related correlation coefficient and reliability is given on the basis of the theory of O.Ditlevsen. Last, an example is given to illustrate the computing method.
