In order to improve the working efficiency and the driving comfort level of the drivers in the armored vehicle occupants, this paper puts forward a new type of ISD (Inerter-Spring-Damper) seat suspension structure which is based on the proposed ISD suspension structure of conventional civil vehicles, in which the structure composition and working principle of the inerter suspension are described. In the case of considering the human body structure, a mathematical model of the ISD suspension was established according to the dynamic equation, and the dynamic simulation of the suspension structure was carried out in the Matlab/Simulink environment. The effects of stiffness coefficients, damping coefficients and inerter coefficients on the overall vibration-damping structure under the series and parallel structures are simulated and analyzed, which provides an important basis for the design and development of the seat model of the armored vehicle.
