摘　　要：为了提高坦克装甲车辆悬架系统的减振性能,提出“惯容-弹簧”准零刚度的基本架构,以惯容、弹簧、阻尼三元件并联作为悬架构型,对惯容连续控制和惯容开关控制两种方案进行动力学仿真和参数优化。研究结果表明:采用准零刚度控制策略后,车体振动加速度大幅度减小,乘坐舒适性改善明显,同时降低了对阻尼系数的需求,提升了减振效率。通过分析悬架减振过程中各元件的瞬时功率,发现可变惯容起能量补偿作用,使一部分振动能量在弹簧和惯容之间反复动态地传递和转换,突破了弹簧缓冲储能、阻尼生热耗能的传统减振机理,达到了更好的减振效能。In order to improve the damping performances of suspension systems for tank and armored vehicle,a basic structure with"inerter-spring"quasi-zero stiffness is proposed.Dynamic simulation and parameter optimization of inerter continuous control and inerter on-off control are carried out with the parallel structure of inerter,spring and damper as suspension system.The results show that the vibration acceleration of vechile body is greatly reduced and the ride comfort is obviously improved with the quasi-zero stiffness control strategy.At the same time,the damping coefficient is reduced and the damping efficiency is improved.By analyzing the instantaneous power of each component in the process of suspension damping,it is found that the controllable inerter plays an role in energy compensation so that a part of the vibration energy can be transferred and converted dynamically and repeatedly between the spring and inerter,breaking through the traditional damping mechanism of spring buffer energy storage and damping heat generation energy consumption,and achieving better damping efficiency.
