摘　　要：磁浮铁路为了实现高速客运 ,大量采用了封闭式高架线路。在德国 Emsland磁浮试验线上 ,采用了混凝土简支梁和钢结构两跨连续梁作为高架线路的主要形式。本文以这两种结构形式为例建立了磁浮铁路车辆 /高架桥垂向耦合模型 ,分别对不同材料和结构形式支承梁以及不同车速时车桥耦合动力响应进行了仿真计算 ,得到两种支承梁结构下系统动力响应特征及车速对耦合系统动力影响规律 ,为磁浮高架线路设计和进一步的系统优化提供了理论依据。文末以我国青城山磁浮线现有的一组基本数据 。Elevated guideway is applied widely in maglev railway system for high speed ground passenger transportation. There are two kinds of elevated beam structures in German Emsland Maglev Test Line--the concrete simply supported beam and the double span continuous steel beam. In this paper, the maglev vehicle/elevated beam guideway vertical coupling dynamic model is built in consideration of the two type of beams, and dynamic responses are calculated and compared for different material, beam structure and vehicle velocity. Then, the coupling dynamic response basic laws are obtained to optimize maglev system parameters for better ride quality and smaller beam impact. Finally, the dynamic responses of Qingcheng Mountain maglev system in Chengdu are simulated.
