| 摘 要： | 在分析了灰色关联分析的基本理论和方法的基础上,考虑到故障诊断中模式的各特征参数的随机性和模糊性引起的模式间"相似性"的形状变异和"相近性"的距离差别,引进了相似系数,将关联度和相似系数联合形成综合关联度,提出了综合关联度分析诊断法,并将该方法用于风机的故障诊断。实例表明,将综合关联度分析法引入风机故障诊断中是可行的,且具有方法简单、计算量小、识别可靠等特点。

| Abstract: | Based on the theory and method of gray relational analysis,the similar coefficient was introduced to reduce the influent of relational degree affected by the maximum value or the minimum value in data and relational coefficient.The suction fan faults were diagnosed according to the synthetical relational degree composed by the relational degree and the similar coefficient.It is indicated that the method is available for the fault diagnosis of suction fan and has the characteristics of simplicity,low computation and high reliability. |

| Keywords: | fault diagnosis gray relational analysis similar coefficient synthetically relational degree |
