摘要
本文基于小波分析的时频特性及其多分辨分析理论,探讨了小波分析在提取大型复杂机械早期故障特征中的应用,并用计算机仿真了小波分析在强噪声背景下检测微弱瞬时信号的优越性能。
Based on the characteristic of wavelet Time-frequency and theory of its muti-analysis, this paper discusses the application of extracting the fault features of mechanical equipment by using wavelet analysis, and also simulates its superior characteristics of detecting weak transient signal in a noisy environment.
