摘要

对空气弹簧减振器整体结构进行了理论建模研究，推导了气弹簧的弹性和刚度特性，为了提高仿真计算的精度，根据阀的开启状态将阻尼阀的阻尼特性分为三个阶段;并分别推导了各截面压缩冲程和恢复冲程阻尼系数的解析表达式。通过程序模拟空气弹簧的特性曲线，比较分析了激励频率、幅值和初始充气压力对空气弹簧特性的影响，所得结果可用于指导空气弹簧的设计。

Mathematical Modeling and Characteristic Simulation of the Air Spring

Theoretical modeling research was carried out on the integrated structure of air spring shock absorbers, the elasticity and stiffness characteristics of the gas spring were deduced, in order to improve the accuracy of the simulation calculation, the damping characteristics of the damping valve were divided into three stages according to the valve opening state, and the analytic expressions of the damping coefficients of the compression and recovery strokes of each section were derived respectively. By programmatically simulating the characteristic curve of the air spring, the effects of excitation frequency, amplitude and initial inflation pressure on the characteristics of the spring were compared and analyzed, the results could be used to guide the design of the air spring.
