By utilisation of CATGEN software all necessary system’s parameters are acquired from CATIA program. There are masses and centres of gravity of inertial elements, coincidence points of EDE and coincidence points of kinematic and dynamic excitations. The first inertial element of the passenger car is the body (Fig.3) that was connected with the axles and the driver’s seat by the elastic-damping elements. By means of two elastic-damping elements (shock absorbers) the body is coupled with the front axle. Two additional EDE (springs and vibration dampers) connect the body with the rear axle and one EDE connects the driver’s seat to the car body.
