摘　　要：针对现有数控机床故障模式影响及危害分析(FMECA)中分析因素少、未考虑因素间相互影响、各因素权重相同等问题,将网络层次分析法(ANP)和数据包络分析OCD模型应用于数控机床使用阶段FMECA的研究,以各因素打分作为输入指标,以经济损失作为输出指标建立OCD模型,并得到各故障模式的效率值,进而提出一种计算风险优先数RPN的新方法,根据(RPN)值得到故障模式的危害度排序。以某型数控机床为例,应用该方法对其进行故障模式影响及危害性分析,验证了该方法的有效性。In view of the existing numerical control machine tool FMECA analysis factors are few,the interaction between factors is not considered and the weight of each factor is the same,the analytic network process(ANP)and data envelopment analysis(OCD)model are applied to the study of FMECA in the use stage of numerical control machine tool,with the score of each factor as the input index.Taking economic loss as output index,the OCD model is established and the efficiency value of each failure mode is obtained.Then a new method is proposed to calculate the risk priority number and the damage degree of failure mode is ranked according to RPN.Taking a numerical control machine tool as an example,the influence and effect of the failure modes are analyzed by using the proposed method,and the effectiveness of the proposed method is verified.
