摘　　要：提出一种运用基于小波降噪的共振解调技术对齿轮齿面接触故障进行诊断的方法。该方法利用小波降噪算法对传感器采集的混合信号进行降噪;采用共振解调技术对降噪后的故障源信号进行频谱分析,成功地提取了齿轮齿面直接接触的故障特征。A method using demodulated resonance technique based on wavelet denoising was developed for gear diagnosis. Employing wavelet denoising, signal of high signal- to- noise ratio was obtained by denoising signal from sensors. Applying demodulated resonance technique to denoised signal, gear contact character information was picked up successfully.
