摘要
实验场地内,通过驾驶某型运输车辆在大正弦路况下的等速行驶,得到多组激励和响应信号。利用频域Hv方法对该车辆的频响函数进行无偏估计研究,并且利用Matlab软件仿真出相应的幅值曲线和相位曲线,为研究该车辆动力学特性及车载货物的合理布置等问题提供理论和实验的指导。
The venue,by driving a certain type of road transport vehicles under a large constant sinusoidal driving,gets multiple sets of excitation and response signals.Using frequency domain methods Hv,an unbiased research of frequency response function of the vehicle is made,and using Matlab simulation software,the corresponding amplitude and phase diagram are draw,and can provide theoretical and experimental guidance for the study of the vehicle dynamics and automotive goods such issues as reasonable arrangement.
