汽车配件质量安全影响因子风险评估

Risk Assessment of Automobile Parts Quality and Safety Factor

文章运用故障模式影响分析(FMEA)方法,对汽车配件质量安全影响因子故障模式、故障机理及故障后果进行分析归纳,构建了汽车配件质量安全影响因子风险评估模型,该模型按故障模式的严酷程度、发生概率、探测度以及风险优先数予以风险等级排序,并以汽车制动软管为例,论述了其风险评估的全过程并给出了评估结果。

The paper analyzes the failure mode, mechanism and results of automobile parts quality and safety factor by the method of Potential Failure Mode and Effects Analysis（FMEA ）. Than, it constructs risk assessment model of automobile parts quality and safety factor, which orders by OPR, ESR, DDR and RPN of failure mode. At last it gives an example for risk assessment of auto brake hose assembly.
