摘要
建立了 6自由度车辆 -乘员非线性动力学系统的理论模型 ,利用小波变换及小波多分辨分析理论研究了该模型在随机性路面下的响应信号 ,并与传统的信号处理方法—短时 Fourier变换方法进行了对比 。
In this paper, 6-DOF nonlinear dynamic system m odel of the vehicle-passengers is formulated. On the basis of wavelet transform and multi-resolution analysis, the signal of the system response on the rough road is analyzed. Furthermore, the difference between wavelet analysis and STFT (Short-time Fourier Transform) is discussed.
