摘要

当高速磁浮列车的悬浮电磁铁处于悬浮状态时，由于吸力和冲击作用，箱体会产生挠曲变形。为了避免箱体变形过程中由于磁轭和箱体耦合产生内应力，设计了一种柔性固定机构用于固定磁轭。在磁轭两侧设计组合式片弹簧，使磁轭处于预紧状态。当磁轭受冲击发生位移时，组合式片弹簧能使磁轭恢复至初始位置，达到磁轭柔性固定的目的。通过片弹簧设计理论和仿真计算，分析片弹簧不同厚度下的“载荷-位移”关系，弹簧刚度和强度符合设计要求，通过试验证明该设计方法是可行且有效的。

Abstract

The box of the maglev electromagnet in the maglev state will produce deflection deformation because of suction and impact. A flexible fixing mechanism was designed to fix the magnetic yoke to avoid the coupling stress between the magnetic yoke and the box in the deformation process. Combined leaf springs were designed on both sides of the magnetic yoke so that the magnetic yoke was in a pretension state. When the magnetic yoke was moved by the impact, the leaf springs can make it return to its original position and achieve goal of the flexible fixation. Through the design theory and simulation calculation, the load-displacement relationship between the leaf spring with different thickness was analyzed, and the stiffness and strength of the leaf spring meeting the requirements were designed. The experimental results showed that the design method was feasible and effective
