摘要: 为提高动车组(EMU)塞拉门运行可靠度,采用模糊层次分析法(AHP),计算塞拉门7种主要故障模式和故障原因的权重大小;引入模糊理论,从故障发生率、维修费用和故障运营影响(晚点)3个风险指标,评价各故障原因的多属性风险指标并得到加权风险评价矩阵;使用模糊区间逼近理想排序法(TOPSIS)相对贴近度计算故障模式,最终得到风险评估结果。研究结果表明:计算结果与近2年的塞拉门现场维护保养记录相吻合,锁闭装置故障、限位开关故障、敏感边缘故障对动车组塞拉门运行可靠度具有较大的危害,需重点检修保养。

Abstract: In order to improve operation reliability of sliding plug door of EMU, fuzzy analytic hierarchy process (AHP) was used to calculate seven main fault modes and weight of fault causes.Fuzzy theory was introduced to evaluate cause of failure from three risk indexes, failure incidence, maintenance cost and failure operation delay. Multi-attribute risk indexes of each fault cause were evaluated and weighted risk evaluation matrix was obtained. TOPSIS was used to calculate relative nearness of fault mode, and result of risk assessment was obtained. The results show that calculated results are consistent with field maintenance records of plug door in recent 2 years. Failure of lock device, limit switch and sensitive edge fault have great harm to operation reliability of plug door of EMUS, need key overhaul and maintenance.

Key words: fuzzy interval, technique for order preference by similarity to an ideal solution(TOPSIS), electric multiple unit(EMU), sliding plug door fault, risk assessment, reliability
