摘　　要：通过建立基于空气悬架系统的汽车整车八自由度平顺性模型,应用MATLAB优化工具箱,结合空气弹簧的特性,分7种工况对空气悬架的刚度和阻尼进行了匹配设计,用MATLAB/S imu link验证了匹配结果并进行了仿真。仿真结果表明:优化后的空气悬架系统对由路面输入引起的振动能够进行有效抑制,能明显改善车辆行驶平顺性。A ride comfort model of automobile was established based on air suspension system, MATLAB optimizing toolbox and characteristics of air spring were used to matching design the stiffness and damping of air suspension system in 7 working-conditions,then computer simulations were carried out and the results were validated under the MATLAB/Simulink environment. The simulation results showed that the optimized air suspension could effectively reduce the vibrations caused by road inputs and apparently improve ride comfort.
