Hydro-regenerative shock absorber with two generators in series for vehicle suspension

This paper presents the design, modeling and fabrication of the prototype of Hydro-Magneto-Electric- Regenerative Shock Absorber (HMERSA) with two electric generators in series for vehicle suspension. The designed HMERSA converts reciprocating linear motion of vehicle suspension into unidirectional fluid flow which turn the two electric generators in series and generate electricity. The HMERSA was modeled and simulated to study the damping force characteristic, the performance, and the generated power. Further, the prototype of HMERSA was manufactured and implemented in the vehicle suspension. The vehicle was tested on a bumping road. The vehicle body acceleration was measured as well as the generated voltage and current. The results are analyzed and discussed in this paper.This paper presents the design, modeling and fabrication of the prototype of Hydro-Magneto-Electric- Regenerative Shock Absorber (HMERSA) with two electric generators in series for vehicle suspension.
