Abstract
Regenerative shock absorber has been developed and investigated widely since last two decades. Several methods have been studied to acquire maximum regenerated electric power, better efficiency and to maintain its performace close to the convensional shock absorber in providing vehicle ride quality. In this paper, a novel study on the influence of battery state of charge (SOC) and electric generator properties on the dynamic characteristic of a hydro-magneto-electricregenerative shock absorber (HMERSA) is presented. The focused study is on how the battery SOC and electric generator properties influence the damping force characteristic, the generated electricity and the efficiency of HMERSA. The battery SOC and generator were tested and the relation between current, voltage and electric torque then formulated based on the test result. The empiric formula of the electric variable were used to develop the dyanmic model of HMERSA and quarter model of the vehicle.The results are reported and discussed in this paper.
