摘　　要：汽车产品的可靠性在整车及零部件企业中受到的关注日益提高,对试件可靠性方法应投入更多研究。我国习惯采用单一部件满足最低要求的方法作为汽车零部件质量要求,较少采用统计的方式对汽车部件可靠性进行评价。对典型的汽车部件试验结果进行分析,给出了对数正态分布及威布尔分布的分析结果,并针对汽车部件的失效判定、道路谱用于疲劳试验提出了相关建议。Today the automobile companies give some attention to the reliability of products, but analysis way need more research. In China, the traditional method of quality requirements for components of cars is that single part meets the minimum requirements, nearly using statistical methods for reliability evaluation. Automotive component test results were analyzed used the method of log-normal distribution and Weibull distribution. Aiming at failure determination of automotive parts and road signals for fatigue test, some suggestions were given.
