A dynamic modelling and simulation procedure for vehicle suspension system based on vector bond graph is described. According to kinematic constraint relations of components, the vector bond graph model for vehicle suspension system is built. In consideration of the coupling of energy variables and coenergy variables in independent energy storage field and dependent energy storage field. The unified formulae of system state space equations which are easily generated on a computer is derived. As a result, the automatic modelling and simulation of dynamics for vehicle suspension system can be realized based on MATLAB.
