Abstract
Keywords: vehicle, energy recovery, shock absorber, hydraulics.
During vehicle running, the shock absorbers are dissipating the energy of a significant mass that oscillates due to external loads, in an effort to damp the energy of those oscillations. Preliminary and basic simulations presented in other papers, have shown that the dissipated energy is significant and part of it may be recovered, for example using a hydrostatic system. The paper presents a new design step for these systems where the recovery task of the whole assembly, vehicle suspension named in this case recovery suspension, is considered together with the damping task. In this case influences like wheel mass, spring rate, tyre damping rate and vehicle speed are considered as influence parameters on energy recovery efficiency.
