基于广义S变换的齿轮箱轴承故障诊断方法
Fault Diagnosis Method of Gearbox Bearings Based on Generalized S transform
摘要
Abstract
The signals of gear box bearing faults usually were nonstationary and nonlinear.It might be more difficult to identify and extract in the strong background signals and noises.Based on the unique features and the time-frequency concentration of the generalized S transform,a rolling bearing fault diagnosis method was proposed based on generalized S transform.Window function in the generalized S transform was discussed,and the influences of different parameters in adj usting the width of window function were analyzed,and the different energy distributions of bearing faults were discussed in time-frequency spectrum by generalized S transform.Finally,the proposed method was validated by simulation analyses and the experiments of rolling bearings.The results show that the proposed method may accurately reveal the rolling bearing fault features frequency,and provides an effective method for gear box bearing fault diagnosis.关键词
