摘要
利用瞬态频率波动法实现频率调制信号的解调，提取齿轮的局部裂纹信息，并通过黄河ＴＮ２５２型汽车变速器疲劳试验的信号分析来验证。
n order to detect the local crack information of gearsl the transient frequency fluctuation method is adopted to demodulate the frequency modolated signals. The method os verified by the signal analysis in the fatigue test of the car gear box of Huang He JN252.
