四滚柱式超越离合器故障的小波变换诊断方法研究

Research on wavelet transform method for fault diagnosis of four roller overrunning clutch

介绍了利用小波变换方法诊断四滚柱式定向离合器故障的新方法 ,并应用基于高斯函数的小波快速算法分离出了故障信号 ,进一步分析了冲击频率。实验结果表明 ,方法行之有效。

This paper introduces a new method of wavelet transform to diagnose the four roller overrunning clutch,and uses the wavelet series based on Gaussian function and its fast algorithm to separate fault signal,further analyzes impact frequency.Experiment results demonstrate the method is effective.
