摘　　要：利用高斯小波进行解包络分析 ,提取包络分析的时域特征参数。对特征参数进行模糊处理和隶属度计算 ,在此基础上设计出故障特征向量 ,进行灰色关联度分析 ,从而把包络解调分析、模糊数学和灰色关联分析有机结合在一起 ,综合它们的优势 ,进行故障分类和识别 。The characteristic parameters in the time domain are obtained by applying Gauss wavelet to envelope analysis (EA). By fuzzying these parameters and calculating the membership degree, fault characteristic vectors are designed and analyzed by gray relational degree(GRD), which could open a new way for fault classification and identification, including Diesel vibration diagnosis by combining the EA and fuzzy method with the GRD.
