齿轮磨损状态的周期平稳信号分析

Periodic stationary signal analysis on gear′s abrasion

对齿轮常见的失效形式——磨损进行分析,并根据实际信号,将时域分析、FFT与周期平稳信号分析相比较.仿真结果表明,周期循环平稳分析方法在提取故障特征方面具有更大的优势.

Analyzes abrasion which is the common failure of gear, and compare time-domain analysis, FFT and periodic stationary signal analysis, periodic stationary signal analysis. The simulation results showes that the periodic stationary signal analysis is the best method to abstract fault characteristic.
