灰色系统理论在机械故障诊断决策中的应用

The Applications of the Grey System in Fault Diagnosis

将灰色关联分析用于机械故障诊断中,完成故障模式识别和诊断决策.为了解决工作实际中故障样本较难获得的问题,引入灰色门限关联分析,用设定门限值的方法,完成对故障发展趋势的简易诊断.

Grey cognate analysis is used in the fault diagnosis. Pattern recognitionand diagnosing decision are fulfilled. In order to resolve the problem that the faultsample is difficult to be acquired in practice, grey boundary cognate analysis isintroduced into this field. By setting boundary value, simple diagnosis is accom-plished.
