摘　　要：针对传统失效模式和影响分析(FMEA)中存在的问题,提出了一种基于区间三角模糊数与灰色关联分析法的改进FMEA方法,并将其应用到加工中心主轴系统的风险分析中。首先,利用区间三角模糊数对失效模式进行评价;其次,利用模糊层次分析法计算风险因子权重值;最后,利用灰色关联分析法对失效模式排序。实例结果表明:FM2(漏油)是风险优先度最高的失效模式。与其他两种方案相比,本文方法能更加合理地对失效模式进行排序。In order to solve the shortcomings of traditional failure mode and effect analysis(FMEA),an improved FMEA method based on interval triangular fuzzy number and grey correlation analysis method is proposed and applied to the risk analysis of spindle system of machining center.Firstly,interval-triangular fuzzy numbers are used to evaluate the level of failure modes and the relative importance of risk factors.Secondly,the weight of risk factors is calculated by fuzzy AHP.Finally,the failure modes are sorted by GRA method.The example results show that FM2(oil leakage)is the failure mode with the highest risk priority.Compared with the other two schemes,this method can sort the failure modes more effectively and reasonably.
