摘要

摘要:
竖向刚度对保证高速磁浮列车在桥上行车安全和乘坐舒适性具有重要意义，是桥梁的重要设计指标之一. 以某3跨连续梁为研究对象，调整截面惯性矩改变桥梁竖向刚度，在不同车速、额定悬浮间隙及温度作用下进行磁浮列车-桥耦合振动分析，讨论桥梁动力系数、车体加速度和悬浮间隙动态变化量随桥梁竖向刚度调整系数的变化规律. 结果表明：刚度调整系数下降至0.75，桥梁动力系数迅速增加，车体竖向加速度相较于悬浮间隙动态变化量对桥梁竖向刚度变化更敏感；车速越大、考虑降温变形时，桥梁竖向动力响应越大，轨道不平顺和额定悬浮间隙对动力系数影响不明显；车速越大、额定悬浮间隙越小，考虑轨道不平顺和降温变形影响时，相同车辆动力响应大小对应的桥梁竖向刚度调整系数越大.

Abstract:
Vertical stiffness is critically significant for the operational safety and ride comfort of high-speed electromagnetic suspension (EMS) trains on bridges, constituting one of the essential design parameters in bridge engineering. By using a three-span continuous girder as the study object, the vertical stiffness was modified by adjusting the cross-sectional moment of inertia. A coupled vibration analysis of the EMS train-bridge system was conducted under varying train speeds, rated suspension clearances, and temperatures. The variation rules of the dynamic coefficient of the bridge, acceleration of the train, and suspension clearance change with the adjustment coefficient of vertical stiffness of the bridge were discussed. The results show that when the adjustment coefficient of stiffness decreases to about 0.75, the dynamic coefficient of the bridge increases rapidly, and the vertical acceleration of the train is more sensitive to the vertical stiffness variation of the bridge than the suspension clearance change. When the cooling deformation is considered, higher train speed indicates greater vertical dynamic response of the bridge, and the track irregularity and rated suspension clearance have no obvious influence on the dynamic coefficient of the bridge. Higher train speed indicates smaller rated suspension clearance. When the effects of track irregularity and cooling deformation are considered, the adjustment coefficient of vertical stiffness of the bridge corresponding to the same vehicle dynamic response is larger.
