基于WSAM的滚动轴承故障IAS信号特征提取

open access: yesZhendong Ceshi yu Zhenduan
将谱幅值调制(spectral amplitude modulation,简称SAM)技术与编码器信号相结合,提出一种基于加权谱幅值调制(weight spectral amplitude modulation,简称WSAM)的滚动轴承故障瞬时角速度(instantaneous angular speed,简称IAS)信号特征提取方法。首先,采用前向差分法对编码器信号进行处理,将得到的IAS信号进行傅里叶变换(Fourier transform,简称FT),得到幅值和相位,保持相位不变 ...
