阶次跟踪和Hilbert包络解调在滚动轴承故障诊断中应用
Application of Order Tracking and Hilbert Envelope Demodulation in Rolling Bearing Fault Diagnosis
摘要
Abstract
A new analysis method combined order tracking with Hilbert envelope demodulation is proposed to fault diagnosis of the wind turbine transmission chain,which is non-stationary and demodulating.Using the order tracking,sampling vibration signals in time domain are resampled in the angle domain,so that the non-stationary signal in time domain was converted into stationary signal in angle domain.It can overcome effectively the " frequency smear" phenomenon,which cannot be solved with the traditional frequency spectrum method.Then,the Hilbert envelope demodulation was used to demodulate the low frequency fault signal from the high frequency cartier signal.关键词
