Abstract:	The electromechanical energy regenerative suspension system is a new type of suspension system, which realizes the vibration damping of armored vehicle body and recovers the vibration energy transmitted to the body from the ground at the same time. According to the working principle of the swing arm electromechanical energy regenerative suspension system, a corresponding mathematical and physical model is established, and a joint simulation model of the vibration damping system and energy regenerative system is constructed based on Adams and AMEsim to analyze the effects of the planetary transmission ratio, the battery resistance, and the torsion buffer stiffness on the system’s damping characteristics and energy regenerative performance. The results show that under four road conditions with a speed of 45 km/h, including paved roads, gobi roads, undulating roads, and gravel roads, the average root mean square value of the vehicle’s acceleration is 4.11 m/s2, and the average energy regenerative power is 1 411.57 W, the electromechanical energy regenerative suspension system has a good damping performance and considerable energy regenerative power; with the increase of planetary transmission ratio, the damping torque and energy regenerative power of the suspension system increase gradually and have a significant effect; with the increase of battery resistance, the damping torque and energy feeding power of the suspension system increase gradually and significantly. With the increase of battery resistance, the damping moment and feed power gradually decrease; the change of torsional buffer stiffness has a small effect on the performance of the suspension system.
