摘要: 针对风险优先数分析法中各评价指标权重相同,且对相同风险优先数(RPN) 无 法进行风险排序的问题,将数据包络法和风险优先数分析法进行融合,对松拉刀机构的故 障模式进行风险分析. 该方法能够增加RPN 分析的区别力,客观寻找故障模式排序方法, 确定松拉刀机构各故障模式的风险等级,有利于设计人员优先处理最危险的故障,为实现 功能部件可靠性分配以及提高松拉刀机构的可靠性提供依据.

Abstract: In the risk priority number (RPN) analysis, each evaluation index weight is the same, and it is impossible to conduct risk ranking for the same RPN value. In view of the above issues, the data envelopment analysis (DEA) and the risk priority number analysis are combined to analyze the failure mode risks of clamping and releasing tools. This method can increase the distinction of RPN, objectively search the failure mode ranking method and determine the risk grades of various failure modes of clamping and releasing tools. Therefore, it is beneficial for the designer to preferentially handle the most dangerous failure mode and can provide a basis for realizing the reliability allocation of function parts and improving the reliability of clamping and releasing tools.

Key words: clamping and releasing tool, failure risk analysis, data envelopment analysis
