摘　　要：基于中低速磁浮车辆选用的线性液压减振器的结构,建立液压减振器的AMESim仿真模型。利用试验与仿真对比方法,对液压减振器AMESim仿真模型开展验证分析,证明建立的液压减振器模型仿真精度高,最大仿真误差仅为8.6%。建立液压减振器-车辆系统的动力学联合仿真模型,从动力学设计角度出发,对横向减振器的安装数量、布置位置等方面进行优化,探讨不同横向减振器安装方式对磁浮车辆平稳性的影响。计算结果表明:横向减振器的安装方式对磁浮车辆垂向平稳性基本无影响;单节车安装8支横向减振器时车辆平稳性最优;单节车安装4支横向减振器时车辆的平稳性次之;不安装横向减振器时车辆端部测点的横向平稳性超出优秀限值。On the basis of the actual structure of the linear hydraulic shock absorber of the medium and low speed maglev vehicle,the AMESim simulation model of the linear hydraulic shock absorber was established and verified.The maximum simulation error of the established hydraulic shock absorber simulation model is only 8.6%,and the reliability is high.Combined with the model of hydraulic shock absorber and maglev vehicle structure,the co-simulation model of shock absorber and vehicle system was established.From the perspective of dynamic optimization design,the installation quantity and layout position of lateral shock absorber were designed,and the influence of different installation modes of lateral shock absorber on the stability of maglev vehicle was discussed.The dynamic calculation results show that the installation modes of lateral shock absorber has little effect on the vertical stability of maglev vehicle.When 8 lateral shock absorbers are installed on the suspension frame of a single car,the vehicle stability is the best.When the suspension frame of a single car is equipped with 4 lateral shock absorbers,the vehicle’s ride stability performances takes the second place.When the lateral shock absorber is not installed,the lateral ride stability performances of the measuring points at the end of the vehicle exceeds the excellent limit.
