摘要
设计了一个基于DSP的车辆滚动轴承的小故障检测系统。运用小波分析和现代功率谱估计法的AR模型法对信号进行谱分析,把正常滚动轴承和故障的轴承信号分解的结果进行对比。验证了小波分析在车辆滚动轴承小故障诊断方面的可行性。
Introduced a system for vehicle rolling bearing's glitch that based on DSP,used wavelet analysis and AR modeling of modern power spectrum estimate's method to analyze the signal.By contrasting the result of the normal rolling bearing and the breakdown bearing signal which are decomposed,it is confirmed that the wavelet analysis to diagnose the vehicles rolling bearing's glitch is feasible.
