This paper presents a finite element model for simulating electrodynamic and magnetostrictive vibration absorber systems. The model employs a decoupled formulation to compute motion induced voltages in a magnetomechanical coupled system. The model is first validated by comparison with experimental measurements. An application of the model for optimization of the system damping performance using model predictions, is presented. The model is also used to calculate the frequency response of a magnetostrictive actuator
