摘　　要：为了分析国产化高速磁浮车辆的试验线路运行性能,开展了小半径曲线通过性能动态仿真研究.根据走行部主要结构参数,初步分析计算了曲线通过时车体与走行部间的几何关系和受力.利用多体动力学及系统分析的协同平台,建立模块化组装的整车动力学与控制模型,并进行R=400 m曲线通过仿真.从分析值与仿真值对比和动车组的多种工况仿真分析来看,模型及仿真结果是基本准确的.In order to analyze the dynamical performance of Chinese-made high-speed maglev vehicle running on the test lines, the dynamical simulations of small radius curved-track negotiations were carried out. Based on the primary structural parameters of walking assembly, the geometric relations and forces acting between carbody and walking assembly traveled on curved- tracks are initially calculated. By the collaborative platform of multi-body dynamics and system analysis, the dynamics and control model of the full vehicle is modularly assembled, and the R = 400 m curve negotiations are simulated. From the contrast analyses between the calculated and simulated values, and further the different velocity running simulation analyses of maglev trainsets, the correctness of the modularized assembling model and simulation results is proven.
