摘要
详细介绍了HHT的理论和算法,然后把该方法用于油膜振荡故障诊断中,并与离散小波变换进行比较,结果证明HHT是处理非平稳信号的一种有效方法。
The theory and algorithm of the HHT is explained in detail. The method has been applied to diagnose fault signal, compared to the discrete wavelet decomposition. Results show that the HHT can effectively be applied to the fault diag- nosis of rotary machinery.
