摘　　要：过程失效模式及后果分析(Process FailureMode and Effects Analysis,PFMEA)是汽车行业广泛使用的重要质量评价分析工具,但很多企业在实际应用时往往流于形式,没有取得实际成效。文章分析了S公司运用PFMEA的成功实践。该公司在新车型量产前运用PFMEA识别出潜在的失效模式及后果,用风险优先级(RPL)量化评估过程风险,并通过设计防错和过程防错对高风险项进行改善,有效降低了产品质量风险,提升了生产效率。PFMEA is an important quality tool widely used in the automotive industry,but many companies often apply it in a superficial manner without achieving practical results.This paper will discuss how S company used PFMEA to analyze four-wheel alignment process before mass production of a new model,identify potential failure modes and consequences,quantitatively assess process risks using risk priority level(RPL),and improve high-risk items through design and process error prevention,reduce product quality risks and improve production efficiency.
