摘要
本文采用主分量自回归谱(Principal Components and Autoregressive Spectrum),简称PCAS方法,对大型离心压缩机设备中的摩擦故障作出了诊断.通过模糊隶属函数给出了摩擦故障的诊断判据.实践表明PCAS方法是有效的.
The Method of Principal Components and Autoregressive Spectrum (PCAS) is adopted for diagnosis of rub fault in large centrifugal compressor. The criterion of rub fault has been obtained based on fuzzy membership function. Practice shows us that PCAS method is efficient.
