摘要 基于某型号加工中心的abc轴进给系统的故障数据,首先进行故障模式、影响及危害性分析(FMECA),然后使用群体决策理论合理地整合团队成员的评估值,采用熵权和专家评估结合方法确定各因素权重,进而计算出abc轴进给系统各个故障的改进危害度(ICR)。根据以ICR为输入数据的决策与试验评价实验室(DEMATEL)方法排列故障优先处理顺序。将最终排序结果与传统危害度排序结果以及改进危害度排序结果进行比较,得到abc轴进给系统的薄弱环节。本文方法也可以用于整机的故障分析和排序,进一步为加工中心可靠性设计和可靠性提高奠定了基础。 The failure mode,effect,and criticality analyses(FMECA) were performed for the failure data of the abc-axis feed system of a certain machining center.The group decision-making theory was used to integrate the evaluation of every team member reasonably,the weight values of the factors were determined by the combinative method of entropy weight and expert evaluation,and the improved criticality(ICR) of every failure was calculated for the abc-axis feeding system.The DEMATEL method with the ICK as the input was used to prioritize the failures.The final prioritizing result by the proposed method was compared with the 2 prioritizing results by the criticality and the improved criticality,and the weak parts of the abc-axis feeding system were found.The proposed method can also be applied to analyze and prioritize the failures of the complete appliance,providing a basis for the reliability design and enhancement of the machining center.
