摘要
提出一种模糊软集的机车制动器高摩擦因数合成闸瓦性能评价方法。首先将评价指标集划分为若干个子集,然后将子集的元素进行组合,使评价参数扩大,最后利用软集运算规则对评价信息进行融合,得到闸瓦的综合性能评价结果。该方法能有效提高决策的分辨率,使评价结果更加准确、可靠。通过对目前我国机车使用较多的4种高摩擦因数合成闸瓦的性能评价,证实了方法的可行性。
An evaluation method of high friction coefficient composite brake shoe performance of locomotive brake basedon fuzzy soft set theory was proposed.First,the evaluation index set was divided into several subsets,then a subset of the elements was combined to make the evaluation parameters expand.Finally,the evaluation information was fused with the softset operation rule to conclude the comprehensive performance evaluation results of composition brake shoe.This method caneffectively improve the resolution of the decision,and make the evaluation results more accurate and reliable.Through theperformance evaluation of 4 kinds of high friction coefficient synthetic brake shoes used more in our country at present,thefeasibility of the evaluation method is confirmed.
