摘　　要：根据齿轮箱振动信号非平稳、非线性的特点,采用局部特征尺度分解方法和倒频谱方法相结合的方式对齿轮箱故障进行诊断。采用局部特征尺度分解方法将齿轮箱断齿实验数据分解成一系列的内禀尺度分量,并对内禀尺度分量进行相关分析,去除虚假分量;将得到的内禀尺度分量进行倒频谱分析,提取出齿轮箱故障信息。仿真分析和实验分析结果表明,该方法对齿轮箱故障诊断有很好的效果。Based on the non-stationary and nonlinear characteristics of gearbox vibration signal, this paper uses local characteristic-scale decomposition method and cepstrum method combine to judge the gearbox fault. Uses local characteristic-scale decomposition method decomposed the experimental data of gearbox faults of tooth breaking into a series of intrinsic scale component and analyze it by using correlation analysis method thereby removing the false component. Analyzes the rest of the intrinsic scale component according to the cepstrum, simulation analysis and experiments analysis prove the method effectiveness for gearbox fault diagnosis.
