Modeling of a vehicle vertical dynamic model using Bond graph

The vehicle is a very complex system which contains basic organs : wheels, pneumatics, trains, chassis and suspensions ... All these subsystems are designed to make the car work in the best conditions. In this paper, we propose to study the dynamic modeling of automobile vehicles by the bond graph methodology. Then we present in this study, modeling and analysis of a system of suspensions for a quarter, half and a whole model of the vehicle. This approach is completely systematic and has enough flexibility to be able to introduce different sub-models in the full model.
