Transient Vibration Reduction of a Powertrain Using MRE Based Adaptive Tuned Vibration Absorber

This paper presents the vibration reduction of powertrain during transient stage by using magneto rheological elastomer (MRE) based adaptive tuned vibration absorber (ATVA). Torsional vibration of power train is represented by a simplified lumped mass multi degree of freedom system to verify the ATVA effectiveness. The equation of motion of the model is developed and simulated in the MATLAB to calculate the vibration characteristics such as natural frequency, damped frequency, mode shape and damping ratio of the power train system. The expressions of the storage modulus and loss factor of the MRE are generated as a function of magnetic field which was obtained from experimental data of MRE available in the literature. The responses of the powertrain system without and with ATVA were compared to verify the effectiveness of the ATVA.
