摘要
分析了地铁车辆3种故障分类下受电弓的可靠性,提出基于改进模糊层次分析法与熵权法的综合评判方法,实现对地铁受电弓发生服务故障时各种故障模式危害性的定量分析。基于三角模糊数、层次分析法、熵权法计算影响因素的主客观权重,在主观权重计算中引入专家权重系数,降低了因专家水平不同带来的偏差,使影响因素权重更加科学。分析结果表明,该综合评判方法对受电弓故障模式的危害度评估结果符合实际情况,而且可以获得更加准确的定量评估结果。
The reliability of is analyzed under three kinds of failure classification for metro vehicles.A comprehensive evaluation method based on an improved fuzzy analytic hierarchy process method and entropy weight method are proposed to quantitatively analyze the various failure modes criticality in the service failure of pantograph.The subjective and objective weights of various influencing factors are determined based on triangular fuzzy number,analytic hierarchy process and entropy weight method.In the subjective weight determination,the expert weight coefficient is introduced to reduce the deviation caused by different experts level,which makes the weight of influencing factors more scientific.The analysis results show that the evaluation results of the comprehensive evaluation method for pantograph failure mode conform to the actual situation,and more accurate quantitative evaluation results can be obtained.
