摘要
提出了基于双谱估计的滚动轴承诊断的方法。利用双谱函数做出滚动轴承故障信号的特征图谱, 并加以分析。实验表明, 双谱可以敏感地监测滚动轴承故障的出现, 并且可以有效地识别滚动轴承不同的故障特征。
A method based on bispectral estimate for ball bearings faults diagnosis was presented.By using of bispectral function,the collection of figures for fault signal feature of ball bearings was presented and analyzed.The experiment shows that bispectrum is very sensitive to the faults of ball bearings and can identify the fault feature validly.
