摘要

共振解调方法是滚动轴承故障特征提取和故障诊断中最为常用的一种方法。然而传统的共振解调技术存在带通滤波参数(中心频率和滤波带宽)需要人工进行预先确定，其具有很大的偶然性、局限性等缺陷。本文作者将快速Kurtogram算法用于共振解调技术带通滤波器参数的确定中，并结合共振解调技术成功运用于滚动轴承的故障特征提取，弥补了传统共振解调方法需要人工干预进行带通滤波参数确定的不足，并分别进行仿真和实验来验证该方法的有效性。

Abstract

The resonance demodulation is an important method in the rolling bearing fault feature extraction and fault diagnosis. But the traditional resonance demodulation method needs choice of proper parameters of the band-pass filter(center-frequency and band-width), which has many shortcomings such as uncertainty and limitation. In the text the fast computation of the kurtogram is used in the choice of parameters of the band-pass filter, following combines it with the resonance demodulation and uses in the rolling bearing fault feature extraction. The method makes up the traditional resonance demodulation method. In the end through simulation signal and experiment verifies the effectiveness of the proposed method.
