Simulation and Performance Evaluation of Hydraulic Transmission Electromagnetic Energy-Regenerative Active Suspension

A new shock absorber with the combined mechanical-electromagnetic-hydraulic structure is proposed to recycle the energy dissipated by shock absorber in the process of driving. The suspension system built on the new shock absorber is generally called hydraulic transmission electromagnetic energy-regenerative suspension. This paper presents the working theories of the hydraulic transmission electromagnetic energy-regenerative suspension, and also builds a kinetics simulation model by applying the interdisciplinary soft ware AMESim. Based on the results of the simulation, the paper makes a comparison between the hydraulic transmission electromagnetic energy-regenerative suspension and the passive suspension, and the results reveal that the comprehensive performance of the former is superior to that of the latter, which proves the theoretical feasibilities of the energy-regenerative suspension of this structure to improve the ride comfort and the fuel economy.
