| Abstract: | Based on bond graph theory, the bond graph model of a vehicle vibration system with five degress of freedom, has been set up, the state equation derived and the dynamic simulation program established. In addition, the vibration responses of a light truck and a light crosscountry vehicle to a triangle obstacle excitation were calculated, the effect of suspension system parameters on vibration characteristics was analyzed. Finally, the comparison between the experimental results and the theoretical calculations and the proposals for improving vehicle ride comfort performances were given in this paper. |
