摘要
通过对振动信号进行解调，提取相位调制信号，得到了故障信息。根据齿轮啮合振动频谱，对齿轮的裂纹进行诊断。
The phase modulated signal is obtained from gear mesh vibration signal demodulation.It provides vital information for identification of gear defects.Based on phase modulated signal analysis and gear mesh vibration spectrum analysis,gear defects, such as gear crack, can be diagnosed.
