摘　　要：机电馈能悬挂系统是一种新型悬挂系统,在实现装甲车辆车身减振同时回收地面传递给车身的振动能量。根据摆臂式机电馈能悬挂系统工作原理,建立了相应数学物理模型,基于Adams和AMEsim搭建了减振系统与馈能系统联合仿真模型,分析了行星变速器传动比、电池电阻和扭转缓冲器刚度对系统阻尼特性和馈能性能的影响。结果表明:在车速为45 km/h的铺面路、戈壁路、起伏路、砂石路4种路面工况下,车身加速度均方根值平均为4.11 m/s 2,平均馈能功率为1411.57 W,机电馈能悬挂系统有良好的减振性能和可观的馈能功率;随着行星变速器传动比增大,悬挂系统阻尼力矩和馈能功率逐渐增大,且影响显著;随着电池电阻增加,阻尼力矩和馈能功率逐渐降低;扭转缓冲器刚度变化对悬挂系统性能影响较小。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 1411.57 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.
