Modelling and analysis of a half car (front-rear) energy regenerating suspension with hydro-magneto-electric shock absorber

Shock absorber is designed to convert the kinetic energy from impact into heat energy that is dissipated. The dissipated energy that is produced by conventional shock absorber is wasted. The aim of this paper is to design the shock absorber that can damp the impact and can harvest energy at the same time. It is called Hydro-Magneto-Electric Regenerative Shock Absorber (HMERSA). This research simulated the HMERSA that applied on a front and rear suspension system of a car. The car speed was varied from 0 km/h to 80 km/h. The phase difference of front and rear suspension’s input were 0° and 90°. The results show that the highest power generated is 165 Watt at car speed of 80 km/h and occurred when the phase difference was 0°.
