基于三维谱峭图算法的共振解调技术研究及应用
Studies and Applications of Resonance Demodulat Based on Three-dimensional Kurtogram
摘要
Abstract
Aiming at the features of periodicity impulsion of vibration signals from rolling bearings with faults,a three-dimensional kurtogram algorithm was proposed,which used the dichotomy of bandwidth and center frequency to search the optimal band with fault signals.The method was applied to select the parameters of band-pass filter in resonance demodulation.Thus,the resonance demodulat was brought forward based on three-dimensional kurtogram.With the running-in test-bed of railway wheel-set,experiments were carried out on rolling bearings with natural faults.The proposed method was used to fault diagnosis.Compared with the resonance demodulat based on fast kurtogram,the proposed method has better identification ability of faults.Finally,time complexity of three-dimen-sional kurtogram algorithm shows its higher efficiency and value for engineering applications.关键词
