摘　　要：为提高车辆在不同行驶工况下的减振性能,建立1/4车辆的非线性动力学模型,提出附加气室容积可调空气悬架系统控制的优化分析及计算方法,设计刚度可调的空气弹簧及空气悬架的决策控制系统。在仿真计算的基础上,进行刚度可调空气悬架系统的台架试验,分析采用决策控制后悬架系统的动态特性。仿真及试验结果基本吻合,实现了根据车辆行驶工况,实时改变附加气室的容积,提高了车辆行驶平顺性。该研究验证了控制策略的有效性,为刚度可调空气悬架系统设计开发提供了新方法。In order to improve vibration absorption performance under different driving patterns, the dynamic mode of quarter vehicle in non-linear system was built and the optimized analysis and calculating method for air suspension with adjustable volume of anxiliary chamber were presented to design air spring of adjustable stiffness and the decision-making control system of air suspension. On the basis of the simulation calculating, bench test of adjustable stiffness of air suspension was conducted, the dynamic characteristics of suspension system after using decision-making control was analyzed. The results of simulation calculating and experiment result were consistent, the function of real-time change volume of auxiliary chamber according to driving patterns was achieved. The study verified the effectiveness of control strategy and it provided a new method for developing the air suspension of adjustable stiffness.
