Modeling Of Dynamic Interaction BetweenThe Structure And The Suspension Of Heavy Vehicles

The modeling of Vehicle Dynamic has been made with several advantages by the Bond Graph Technique, due its large employment and its computational approach that allows the analysis of complex system.

This paper shows the bond graph capacity to represent the distributed parameters system of the vehicle structure that was modeled by the Finite Element Method.

Because of the great number of degrees of freedom, we must represent the system by multibonds. This make easy the mathematical manipulations of the equations to obtain the state space model of the problem.

We present some results of the simulation where we can interpret the physical behavior of the system over working condition.
