摘　　要：以油气弹簧的刚度特性为参考,借鉴离散化的思想并结合螺旋弹簧的理论知识,建立变参数螺旋弹簧压缩过程的数学模型.结合实际车辆装配尺寸,通过编制Matlab程序对变参数螺旋弹簧的参数进行解析计算.并将变参数螺旋弹簧刚度曲线与油气弹簧的刚度特性曲线相比较,结果表明变参数螺旋弹簧的刚度特性可以接近油气弹簧的刚度特性.The mathematical model of variable parameter helical spring compression process is established based on discrete concept and basic theory of helical spring. Based on the stiffness characteristics of hydro-pneumatic spring and taking the actual vehicle assembly dimensions as the constraint, the structure parameters of the variable parameter helical spring were calculated by Matlab program. By comparing the stiffness characteristic curves, the results show that the stiffness of variable parameter spring can be close to the stiffness of hydro-pneumatic spring.
