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.
In the risk priority number （ RPN） analysis , each evaluation index weight is the same , and it is impossi-ble 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 relea-sing 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 .
