In this article, the dynamic model of the support system for vehicle-mounted spherical magnetic suspension flywheel battery (SMSFB) is established and analyzed. Firstly, a seven degree-of-freedom (DOF) automotive model is established. Based on this, the effects on the SMSFB support system caused by the vehicle start-up acceleration, braking deceleration as well as the uneven road caused vibrations are analyzed. Then, the detailed expression of the radial suspension force generated by the suspension control current is derived. Finally, the dynamic model of the SMSFB support system is built and analyzed by the co-simulation of ADAMS and MATLAB. The simulation results show that the SMSFB support system provides a fast rotor suspension performance and is capable of maintaining the flywheel rotor stability under complex road conditions and changing vehicle driving conditions.
