摘　　要：对车辆的振动信号的处理采用小波分析的方法,找出车辆振动的本质特征,从而对车辆的舒适性或运行状态作出客观的评价,并为车辆的减振降噪提供实际依据。从小波变换、多分辨分析、系统中振动信号的小波分析几个方面进行详细阐述。在分析方法上提供了一种新的分析技术,为车辆振动本质特征的研究拓宽了理论基础。This paper adopts a method of wavelet analysis to dispose vibration signal. The purpose is to obtain an objective evaluation about the comfortableness of the vehicle. The thesis systematically formulizes in wavelet conversion, Multi-Resolution Analysis and wavelet analysis of the vibration. It provides a kind of technology and broadens the theory foundation about the natural features of vehicle vibration.
