School of Mechanical Engineering, Southwest Jiaotong University, Chengdu 610031, China

摘要

摘要: 针对中低速磁浮道岔，建立磁浮车辆-道岔梁耦合振动分析的数学模型，以分析磁浮列车通过道岔主动梁时的梁振动为研究目标。采用有限元软件对主动梁进行静力学分析，然后逆求主动梁的等效刚度曲线，并运用拉格朗日动力学方程建立磁浮车辆-道岔梁刚体动力学模型。基于动力学仿真软件，对磁浮车辆-道岔梁进行刚体动力学仿真，得到列车通过道岔时道岔梁中点垂向位移曲线图。然后采用ABAQUS和SIMPACK联合仿真，对主动梁进行刚柔耦合动力学仿真。分析结果表明：梁的刚度和重量对梁变形影响很大，对柔性主动梁动力学分析得出的垂向位移量大于刚体主动梁的位移量，柔性主动梁更与实际情况接近。

Abstract: In this paper, the coupled vibration analysis model of medium-low speed maglev train and active turnout girder is established, and the vibration of the girder as the research target when the maglev train passes the turnout girder. The finite element software is used to carry on the static analysis of the active turnout girder, and the equivalent stiffness curve of the active turnout girder is obtained. Rigid body dynamics model of the maglev train and turnout girder is established with Lagrange dynamic equation. Based on the dynamic simulation software, dynamic responses of the magnetic levitation train and turnout girder were simulated, and the vertical displacement curve of the turnout girder was obtained when the train passed the rigid turnout girder. Then the rigid-flexible coupling dynamics of the active turnout girder was simulated by ABAQUS and SIMPACK. The results show that the stiffness and weight of the girder have a great influence on the deformation of the girder. The vertical displacement of the flexible active turnout girder is larger than that of the rigid active turnout girder, and the flexible active turnout girder is closer to the actual situation.
