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.
