| 摘 要： | 分析了在发动机设计中实施设计故障模式及后果分析(DFMEA)的困难,以节流阀体的改进设计为主线,提出了确定DFMEA详细分析对象的方法,减少了分析对象的数量,节省了工作时间;对DFMEA流程以及严重度的判定进行了改进并提出将其所分析的项目划分为基础项和衍生项新概念,利用改进的DFMEA方法,分析出节流阀体的故障原因与影响,并提出了相应的建议措施,结果表明,DFMEA更适于在内燃机行业的使用与推广。

| Abstract: | Difficulties of design failure mode and effect analysis(DFMEA) application of engine design are analyzed,and some research has been made in the improved design of throttle valve casing of one Chinese made gas engine.The method of Defining detailed DFMEA object is provided,which reduces the DFMEA's object number,and save time on DFMEA.The DFMEA's flow and severity determinant rule are improved,and the basic item and related item in analysis process are proposed,which make DFMEA more suitable in engine design.The improved DFMEA is used to analyse the throttle valve casing's failure cause,effect and some recommend corrective actions are attained successfully. |
