Research on the Principle of Arm Torsion Electromagnetic Active Suspensison

In order to explore the working principle of the arm torsion Electromagnetic Active Suspension (ITEAS), this paper studies the three functions of height adjustment, stiffness adjustment and damping adjustment based on the basic structure of ITEAS. Firstly, the mathematical model of height control of ITEAS is built according to the working principle, and then the ITEAS is established according to the tire mass and the motion form of the body Based on the two degree of freedom 1/4 suspension model, the stiffness active adjustment model and damping active adjustment model are built respectively, and verified in the MATLAB / Simulink module. The results show that ITEAS can effectively realize the stiffness active adjustment and damping active adjustment according to the road excitation.
