摘 要:将灰关联聚类分析法用于CJ20系列接触器动态性能评价,以9台CJ20-25型交流接触器为评价对象,实现动态性能的等级划分和优劣排序两种评价.提出针对"样本-相角-指标采样值序列"三维数据的算法步骤和公式,分别采用区间数和实数两种类型进行决策评价,并分析了这两种数据处理结果存在差异的原因.分析表明:灰关联聚类分析法用于评价动态性能可同时实现等级归属评价和性能优劣评价;在性能评价时考虑全相角范围,区间数算法比结合统计学实数的算法更易受极值影响;若研判特定相角下的性能,鉴于目前尚无公认统一的区间数排序方法,故结合统计学中实数算法的评价结果更合理.Grey-correlation&clustering method is applied to evaluate the dynamic characteristics of CJ20 series contactor.Nine CJ20-25 AC contactors were chosen to rank and to sort their dynamic performance.This paper proposes the steps and formula of the algorithm in detail which aims to“samplephase-sampled value sequence”.Two data forms including interval and real numbers are used in the method,and the causes of difference between the two forms are analyzed.The analysis shows that:the grey-correlation&clustering method could be used to rank and sort at the same time,if taking the whole angles into account the interval number algorithm will be more susceptible by extreme data than real number one,if taking some specified angle into account,in view of the fact that until now there is still no certain and correct method how to rank the interval numbers,so the real number algorithm combined with statistics is more reasonable.
