摘要： 以一种装甲车用双气室油气弹簧为研究对象，探究影响其非线性刚度特性的因素。首先运用达朗伯原理建立其非线性刚度特性的理论方程并进行数值求解，然后通过实验验证了模型的合理性；进一步分析其主要工作条件和结构尺寸对刚度特性的影响。结果表明：油气弹簧的刚度特性与输入位移激励是非线性的关系，刚度系数会随着支撑质量、蓄能器初始气体压力、反压腔初始气体压力、主腔室面积的增加而增大，随着蓄能器初始气体体积、反压腔初始气体体积、环形腔面积的增加而减小。

Abstract: This article takes a dual-chamber hydro-pneumatic spring for armored vehicles as the research object, and explores the factors that affect its nonlinear stiffness characteristics. First, using D′Alembert′s principle to establish the theoretical equation of its nonlinear stiffness characteristics and numerically solved, and then the rationality of the model is verified through experiments; the influence of its main working conditions and structural dimensions on the stiffness characteristics is further analyzed. The results show that the stiffness characteristics of the oil-air spring have a nonlinear relationship with the input displacement excitation. The stiffness coefficient will increase with the increase of the support mass, the initial gas pressure of the accumulator, the initial gas pressure of the back pressure chamber, and the area of the main chamber. As the initial gas volume of the accumulator, the initial gas volume of the back pressure cavity and the area of the annular cavity increase, the stiffness coefficient decreases. The research results can provide research methods and theoretical references for the optimization of the parameters of the dual-chamber hydro-pneumatic spring and its application in the field of armored vehicles.
