A Tuned Vibration Absorber (TVA) is used to minimize the vibrations of mechanical machines and structures subjected to harmonic force excitation. However, it is achieved at the expense of large vibration amplitude of absorber mass. Nagem et al. have addressed this problem by replacing the TVA by an Electromechanical Vibration Absorber (EMVA). In this paper, in the approach of Nagem et al., the equations of motion transmissibility and current transmissibility of an EMVA are obtained using the parameters of mechanical subsystem and the electrical subsystem. Non-dimensional frequency response curves for the motion transmissibility and current transmissibility are plotted for different values of mechanical damping ratio 𝝃𝟏 and electrical damping ratio 𝝃𝒆 of EMVA. It is seen that with the increase in the values of 𝝃𝟏 and 𝝃𝒆 , significant reduction in the resonant response of primary system is achieved when the primary system is subjected to harmonic force excitation. The excitation frequency band over which the EMVA is effective is also increased. The resonant values of current in the shunted electrical RLC circuit are considerably reduced resulting in less energy loss in the electrical circuit.
