摘　　要：提出了预缩整理机磨辊动平衡灰色关联分析诊断模型。针对A型灰色关联分析模型和B型灰色关联分析模型存在的问题,采用混合关联度分析模式,以加权的方法将二者有机结合起来。选择磨辊振动信号中恰当的时域和频域参数为故障特征参数,通过比较检测状态模式与标准故障模式的关联度判别磨辊动不平衡故障,诊断方法简单方便,结果准确可靠。A grey relation grade analysis model of tidy machine counter the problem which A grey relation grade analy gri sis nd roll moving balance diagnosis was presented. To and B grey relation grade analysis existed, two grey relation grade analysis was combined by giving weight so as to develop merit and evade weakness. Extracting appropriate characteristic parameters of fault vibration signals, tidy machine grind roll moving balance fault diagnosis was finished by checking test samples against standard sample. The diagnosis method is simple and the result is accurate
