Research on Estimation of Frequence Response Function of Certain Transport Vehicles Based on MIMO Experimental Conditons

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.
