齿轮发生裂纹故障时其振动信号会产生调制现象,包括幅值调制和频率(相位)调制两部分。目前调幅信号的解调分析已经比较成熟,但对于调频信号的解调方法研究还不够完善。全面系统介绍了近年来处理调频信号
中最常用的希尔伯特相位解调和循环平稳解调两种方法-Gear crack fault occurs when the vibration signal will produce modulation phenomenon, including the two parts of the modulation of the amplitude modulation and frequency (phase). AM signal demodulation analysis is relatively mature, but still not perfect FM signal demodulation method. The comprehensive system introduced in recent years dealing with the FM signal most common Hilbert phase demodulation and cyclostationary two methods
