中文摘要：

根据汽车制动系统和轮胎的典型故障模式分别建立了故障树,利用D-S理论中的似然函数和信任函数分别作为故障树分析底事件发生故障概率区间的上、下界。采用区间分析理论,分别构造了与门区间算子、或门区间算子,对底事件的概率区间进行区间数值运算,解决故障树的量化计算问题,从而获得了顶事件发生故障的区间概率。分别对制动系统和轮胎的可靠度进行了预测。计算结果表明了文中方法的有效和可行性,并可为汽车制动系统和轮胎设计方案的改进和调整提供了参考依据。

英文摘要：

Fault tree of automotive brake system and tire were set up according to their typical failure modes. We use the likelihood function and belief function of D-S theory respectively as the fault tree to analyze the upper and lower bounds of bottom event fault probability interval,we also apply the interval analysis theory to construct the AND operator,OR operator,and we conduct numerical computation on bottom event fault probability interval to solve the quantitative calculation problem of fault tree,thus to obtain probability interval of the top event fault,and reliability of automobile tire and brake system are analyzed and predicted. The calculation results show that this method is effective and feasible, which provide a reference design for improvement and the adjustment of automotive brake system and tire.
