| 摘 要： | 为了对离心式压缩机振动故障进行诊断，简要介绍了小波分析的特点和小波变换的原理，利用离散正交小波对离心式压缩机转子正常工作和非正常工作时的振动信号进行了分析和多层小波分解。使其突变信号和非平稳信号与平稳周期性信号分开，达到了故障诊断的目的。 |
| 关 键 词： | 小波分析 离心式压缩机 振动 故障诊断 |

| Abstract: | In order to diagnose the vibration fault of centrifugical compressor,introduced are the characteristics of wavelet analysis and the principle of wavelet transform.Making use of discrete orthogonal wavelet,analyzed are the vibrational signals of centrifugual compressor's rotor in normal and abnormal operating conditions,the signals are decomposed into many layers,its mutation and unsteady signals are separated from steady periodic ones and the final objective is carried out. |
| Keywords: | Wavelet analysis Centrifugal compressor Vibration Fault diagnosis |
