摘　　要：为了提升汽车的行驶平顺性及其适应路面时变的能力,针对电控空气悬架刚度分级调控问题,提出一种基于磁流变材料的新型一体式悬架减振支柱设计方案,在电控主动空气悬架的减振支柱基础上进行改进,利用磁流变材料的特性达到悬架系统无级调控刚度和阻尼的要求.介绍了减振支柱的结构组成及工作原理,分别建立了刚度和阻尼特性数学模型.搭建试验台架,进行了力学特性试验,得到减振支柱刚度和阻尼特性曲线,并利用试验结果对模型进行参数辨识.将仿真结果与试验结果进行对比分析,结果表明该减振支柱的数学模型较准确,设计方案可行.To improve the ride comfort of car and the adapting ability to the time⁃varying road surface,a new integrated suspension design scheme based on magnetorheological materials was proposed to realize the graded regulation of stiffness for the electronically controlled air suspension.The damping pillar of the air suspension was improved based on the characteristics of magnetorheological materials to achieve the infinite regulating of stiffness and the damping of suspension system.The structural composition and working principle of the damping pillar were introduced,and the mathematical models of stiffness and damping characteristics were established respectively.An experimental bench was set up to identify the model parameters according to the experimental results,and the simulation results were compared with the experimental results.The results show the mathematical model of damping pillar is accurate,and the design scheme is suitable.
