摘要
对汽车道路试验中测得的座椅处的振动信号进行了分析,将小波阈值去噪方法用于对该信号的去噪,并在MATLAB中实现了去噪算法.实验证明,小波阈值去噪方法非常适合于汽车道路试验振动信号的检测.
The vibration signal of the seat in automobile road test is analysed text. Wavelet threshold denoising is applied to it and calculation method is realized in MATLAB. The experiment shows that such method is suitable for detecting the vibration signal in automobile road test.
