| 摘 要： | 广义谐波小波可任意选取频带,是理想的带通滤波器。将广义谐波小波结合共振解调技术,可较好地提取轴承故障激发的共振信息。应用该方法,对某转炉耳轴轴承进行故障诊断,诊断结果与实际情况相符。

| Abstract: | General harmonic wavelet is an ideal band- pass filter, due to selecting frequency range discretionarily. The fault characteristic of rolling bearing can be extracted via integrating general harmonic wavelet and resonance demodulation technique. By the proposed method, the rolling bearing fault of a converter trunnion was detected. The diagnosed results are consistent with the fact. |

| Keywords: | general harmonic wavelet low speed heavy-duty bearing resonance demodulation fault diagnosis |
