摘要
分析了有故障的滚动轴承在运转中的振动信号特征 ,采用一种无频带错位的小波包算法进行滚动轴承的故障特征信号提取 ,清晰地刻画出轴承故障冲击的特征函数 ,通过试验证明了该方法的有效性 。
The character of vibration signal caused by failed bearing is analyzed.Based on wavelet packets algorithm without frequency band derangement,a signal character extraction method of rolling element bearing failure measurement is proposed.The character function portrays distribution condition of failure impact precisely.The practical example shows the reliability and the method has a high signal to noise ratio.
