基于小波包络谱分析的减速机故障诊断研究
Speed Reduce Fault Diagnosis Base on Wavelet and Envelope Analysis
【摘要】 介绍了小波分析方法,以小波分析和包络谱分析在故障诊断中的应用为例子,利用小波分析信号突变的特点,利用Hilbert包络并进行频谱分析,体现了小波包络谱分析的优越性,实现故障诊断的目的。
【Abstract】 Introduces the wavelet analysis and the application of wavelet analysis and envelope analysis in the speed reducer,take advantage of fault always happens with the output signal sudden change,use Hilbert envelope and take spectrum analysis,it proved that wavelet analysis and envelope analysis has the superiority,realizes the purpose of fault diagnosis.
