摘　　要：结合胶轮车的使用工况和结构特点,介绍了胶轮车油气悬架系统,推导出其刚度的数学模型。根据刚度公式编程运算得出蓄能器初始充气压力、蓄能器额定充气容积、悬架负载以及气体多变指数对刚度的影响规律,为胶轮车油气悬架系统的设计打下基础。Combing with the applying working condition and structural characteristics of the rubber-wheel vehicle, the hydro-pneumatic suspension system of the rubber-wheel vehicle is introduced and the mathematical model of its stiffness is deduced. The influence laws of the initial inflation pressure and the rated inflated volume of accumulator, the suspension load and the air polytropic exponent on stiffness are obtained according to the programming operations by the stiffness formula. It lays a foundation for the design of hydro-pneumatic suspension system of the rubber-wheel vehicle.
