Effective shock absorption of the body in the presence of excitations of a random nature results in the necessity of using vibration dampers. The classic solution is the viscous damper, which works by dissipating mechanical energy in the form of heat generated to the external environment. The characteristics of the flexible components in car suspensions (elastic and damping) affect the transfer of mechanical energy. The purpose of the research was to develop a method for assessing the impact of damping in a suspension system on the transfer of mechanical energy from unsprung masses to the body. The assumed research goal was carried out on a vehicle model with two degrees of freedom, whose parameters corresponded to the real object. The developed method uses energy relationships occurring between selected variables of the vibrating motion of inertial elements of a motor vehicle. The results obtained during simulation tests were empirically verified on a real object. The proposed method allows to assess how the damping in the suspension system affects the energy relationships occurring in the vehicle suspension vibrating motion.
