Abstract: Energy-recycle type active suspension (ETAS) using magnetic force has been proposed and modified by MacPherson suspension, with the purpose to decrease the vibration of vehicle suspensions and recycle the energy generated by shock absorbers. This paper proposes a new type voice coil motor (VCM) embedded in the conventional shock absorber and realized its functions with two working modes. Based on the ETAS, magnetic field distribution in air gap of the VCM is analyzed by theoretical model and finite element method (FEM) analysis, which validates the accuracy of the theoretical model and preliminary optimization. Then, dynamic models of the 1/4 ETAS with two working modes are established to certificate the impact of the two modes during the vehicles operation. Finally, energy consumption and recycle are respectively simulated under the standard C-level road surface, which investigates the efficiency of the ETAS system. The simulation results show that average powers of energy consumption and energy recycle are 9.29 W and 1.81 W, the efficiency of the ETAS system is 19.5%.
