摘　　要：为研究悬架组的动力学特性,针对某大吨位全路面起重机,介绍其单桥上互连式双气室油气悬架的结构和原理,建立单桥动力学模型和液压模型,并采用AMEsim建立仿真模型。分析在连续振动路面和冲击作用路面2种典型工况下,车身垂直方向的位移、速度和加速度的输出特性曲线,并对悬架的减振性能进行评价。结果表明:此油气悬架系统具有非线性变刚度、变阻尼的特点,可满足大吨位全路面车辆的减振要求。Output characteristics of oil-gas suspension in an all-terrain crane.In order to study dynamic features of vehicular suspension brackets we in view of a heavy duty all-terrain crane introduced structures and principles of the oilair suspension at a single axle to have constructed mechanic models and hydraulic models for single axles while building simulation models by adopting AMEsim.On the basis of analyzing the crane's continuous vibration and impact effects under 2 typical travel and work conditions to detect output characteristic curves while evaluating vibration damping functions of the suspension.Results show that such oil-gas suspension system has got features in variable rigidity and damper that can satisfy damping requirements for high capacity all-terrain vehicles.
