摘要
利用Solidworks、ANSYS以及SIMPACK软件,建立了包含车辆、控制系统和弹性悬浮架的高速磁浮车辆刚弹性动力学模型,仿真分析了车辆以250km/h速度通过半径2260m平面曲线时弹性悬浮架的动态响应。结果表明,在线路扭转最为剧烈的缓和曲线中点,悬浮架弹性变形最大,其弹性扭转角最大约0.125°,悬浮臂最大垂向变形为0.44mm;悬浮架弹性变形主要在缓和曲线上得到反映,在圆曲线段上近似为一较小值,扭转变形方向在前、后缓和曲线上刚好相反。弹性悬浮架的动态响应规律与曲线通过理论是吻合的,表明磁浮车辆刚弹性动力学仿真模型是合理的。
Using the Solidworks,ANSYS and SIMPACK software,a complete rigid-elastic dynamic model of high-speed maglev vehicle system was set up,including the vehicle,the controller and the elastic levitation chassis. Dynamic responses of the elastic levitation chassis running over the 2260m-radius plane curve track were calculated on the condition of 250km/h curving speed. Numerical results show that the maximum elastic deformation appears on the medium position of the transition curve,where the torsion rate of the curve track reaches its maximum. The maximum torsion angle of the levitation chassis is almost 0.125° while the C-shaped arm has the maximum vertical deformation,0.44mm. The elastic deformation mainly reflects on the transition curve,and approximates to a small constant value on the circular curve. The torsion direction of the levitation chassis on the front transition curve is contrary to that on the rear one. Dynamic responses of the elastic levitation chassis accord with the curve negotiation theory,wh Using the Solidworks,ANSYS and SIMPACK software,a complete rigid-elastic dynamic model of high-speed maglev vehicle system was set up,including the vehicle,the controller and the elastic levitation chassis.
