A High-Efficiency Energy Harvesting by Using Hydraulic Electromagnetic Regenerative Shock Absorber

This article intends a hybrid energy-harvesting shock absorber design which comprehends energy harvesting of automobile suspension vibration dissipation. A mathematical model the prototype is established, and simulation results show that dissipation can be recovered by varying feed module, thereby got damping forces (DF) ratio at different compression extension stroke. The conversion from hydraulic to mechanical mainly then converted into electrical furthermore, we recharge our battery this energy. advanced proposed maximum ride comfort meanwhile fuel saving. shows verifying it with test results. DF expansion stroke higher than characteristics curves speed verify validity prototyping damper amplitudes off-road vehicles. Hydraulic Electromagnetic Regenerative Shock Absorber (HERSA) characteristic tested in 65 watts 1.67 Hz excitation frequency. So, 14.65% recovery efficiency 20 mm rod diameter 8 cc/rev motor displacement. HERSA examined has ideal performance as standard requirements National Standard QC/T 491-1999.
