Description
Suspension system plays a significant role in automobiles to enhance and improve ride comfort and road handling. In this paper, an independent front and rear passive suspension is performed on a half car model to analyze the reaction force exerted by the front and rear wheel and simulate these forces due to bounce and pitch degrees of freedom of the car. In this suspension model, the bounce degrees of freedom is represented by the vertical displacement and the vertical velocity and the car body pitch is represented by pitch angular displacement and pitch angular velocity. To obtain essential and accurate results about the performance of the suspension system, the effect of some system parameters such as the front and rear spring stiffness, as well as the front and rear dampers coefficients were studied. Matlab Software is used for numerical simulation of this half-car suspension model.
