N2 - The performance of a regenerative shock absorber is not only determined by the amount of the regenerated energy (electricity), but also determined by its ability in providing ride comfort. The damping force characteristics produced by its mechanical component and its electrical system, including electric generator will influence the overall damping characteristics of the regenerative shock absorber. This paper reports the method of how to design a hydro-magneto-electric regenerative shock absorber (HRSA) to gain performance closed to conventional shock absorber (CSA) in providing ride comfort and gain maximum electricity. The proposed HRSA was designed to have hydraulic cylinder-tube system, gear system, hydraulic motor and electric generator. Based on the damping force characteristics test result of the typical CSA, the design parameters of the proposed HRSA, such as: Gear inertia, gear ratio, cylinder-tube diameter ratio and oil viscosity were modified to obtain the expected performance closed to CSA. The modified HRSA was mathematicaly modeled, simulated and the results were compared to the CSA. To validate the mathematical model, prototype of HRSA was fabricated and tested. A quarter car model of vehicle with HRSA suspension was fabricated and tested. The acceleration of the vehicle body (sprung mass) and the generated electricity from HRSA were measured. Further, the prototype of HRSA was implemented in a pickup truck and tested in a bumping road. The results were reported and discussed in this paper.
