Vehicle Dynamic Testing Data Processing Using Wavelet Analysis

Abstract

Abstract-The vehicle dynamic test data usually have some noise which would bring serious negative effects. In order to accurately obtain vehicle dynamic response. The test datas must be denoised using suitable signal denoising method. For this purpose, the basic principle of wavelet analysis is presented and the method of wavelet threshold denoising is used in automotive handling and stability test data processing. The denoising result shows that the wavelet denoising method is effective. And it provided a theoretical basis and practical engineering experience for vehicle handling and stability test data de-noising processing.
