A computer model of the car suspension in the SimInTech program has been developed. The model includes three «Inertia» blocks, corresponding to the weight of the wheels and the body of the car. The spring elements are defined by the «Translational spring» blocks, and the damper elements are defined by the «Translational Friction damper» block. The impact from the road is considered in the form of some equivalent sinusoidal oscillations of the forces applied to the wheels, taking into account their phase shift and the speed of the car.
