摘要
用谱分析技术诊断齿轮箱故障。总结了诊断齿轮箱故障常用的几种谱分析法及其特点。从实例的几种谱分析结果中,可看出自回归谱有更高的精度和谱分辨率,从而较客易而准确地找出故障的主要频率成分。
The spectral analysis techniques are used to diagnose fault of gearboxes. Many analytical methods developed in recent years are summarized. By means of these methods,gearbox vibration signals are analysed. The results show that the autoregressive spectra are with higher accuracy and resolution than FFT spectra.
