摘要
以某多轴轮式无人平台车辆为研究对象,分别建立了同侧互连平衡油气悬挂和独立油气悬挂数学模型,并基于MATLAB建立了仿真模型,重点对车辆正常行驶状态下的2种悬挂系统输出力特性及刚度、阻尼特性进行对比分析,并就整车的行驶平顺性进行了实车测试。结果表明,同侧互连平衡油气悬挂有效降低了整车平台所受到的垂向振动冲击力,平台质心处垂向加速度均方根值降低了0.383 g,提升了整车平台的行驶平顺性。
Taking a multi axis wheeled vehicles unmanned platform as the research object,establishing mathematical model of ipsilateral interconnection equilibrium oil gas suspension and independent oil and gas suspension,establishing the simulation model based on MATLAB,the output force characteristics,stiffness and dampincharacteristics of two kinds of suspension on vehicles moving condition are mainly compared,the riding comfort of vehicle are tested.Results show that:the ipsilateral interconnection equilibrium oil gas suspension effectively reduces the vertical vibration impact force on the platform,and the vertical acceleration at the center of mass of the platform decreases by 0.383 g,which improves the ride comfort of the platform.
