摘要:针对中低速磁浮列车悬浮系统，基于向量式有限元法建立可变刚度的高架轨道梁模型，同时基于牛顿力学方程建立车辆系统模型，并通过可控悬浮电磁力将2个模型耦合。以轨道梁的跨中位移、梁端转角、振动加速度以及悬浮间隙偏差值为重要指标，从所提出的车?桥磁力耦合模型出发，通过数值仿真得到磁浮列车及轨道线路相应结构构件的振动响应及位移变形响应规律。最后，通过全尺寸磁浮列车现场试验初步验证所提出的磁力耦合模型的有效性。



Abstract:For the levitation system of medium-low speed maglev train， an elevated rail beam model with variable stiffness based on vector form intrinsic finite element method and a vehicle system model based on Newtonian mechanics equations were established. The two models were coupled by controllable levitation electromagnetic force. Then， the mid-span displacement of rail beam， the angle of beam end， the vibration acceleration and the deviation of suspended airgap were taken as the important indexes. The vibration response and the displacement deformation response of the corresponding structural component of maglev train and track line were obtained through numerical simulation based on the proposed coupled model of vehicle-bridge magnetic force. Finally， the effectiveness of the proposed magnetic coupling model was verified through the field experiment of full-size maglev train preliminarily.
