对所建立的故障树进行了定量计算.以某汽车驱动桥为实例

对相关方法的应用进行了分析

结果表明

应用三角型和正态型模糊数方法的计算结果差别不大

轴承磨损失效是该汽车驱动桥分系统失效的关键事件.

Abstract

An fuzzy fault tree analysis for automobile drive axle system was proposed. The theory of fuzzy fault tree was introduced as well as the structure of automobile drive axle

the fault tree of the automobile drive axle system was established. The ascending method was used to find minimal cutting sets. The fuzzy numbers were employed to describe the fault probability. Furthermore

the interval representation and calculation strategy were presented when both triangular fuzzy number and normal fuzzy number were chosen to describe the fault probability. An example of a automobile drive axle system shows that the difference between fuzzy fault tree with triangular fuzzy number and normal fuzzy number is not significant and baring wear is the key failure event in this automobile drive axle.
