摘要
分析了汽车传动轴故障的振动特征;研究了传动轴振动信号的试验提取方法;分别对传动轴振动信号进行了傅里叶变换处理分析和小波分解处理分析,得到了相一致的结论。
The vibration characteristic of automotive drive shaft trouble is analyzed. The test extraction method of drive shaft vibration signal is studied. Fourier transformation anti wavelet decomposition aye respectively treated anti analyzed for drive shaft vibration signal, then concurrent conclusion is obtained.
