Behavioral Model and Analysis of Mechanical and Electromechanical Dampers in Light Vehicles

this paper represents an analytical model of mechanical dampers for sinusoidal input force and the energy dissipated at different excitation frequencies. Modeling of electromechanical damper is achieved by tuning the gain and order of the electromechanical damper with the mechanical damper with respect to transfer function so that road safety and comfort is not compromised. Simulation results in case of mechanical dampers shows peak energy dissipation of 3.61mJ for a very low amplitude (0.5cm) sinusoidal force input at resonant frequency of 1.21 rad/s. The displacement of damper reduces with increase in frequency and thus energy dissipation also decreases.
