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.

: Urban rail transportation has many advantages, such as safety, comfort, high speed, large capacity and so on. Because of the high construction costs, its application has been limited. When the vehicles are driven by linear motors, the height of the vehicle, tunnel section and construction costs can be reduced. Since the traction of linear motor driven railcar has nothing to do with the factor of adhension, the transportation system have a low noise and losses which come from wheel-rail friction.

: Urban rail transportation has many advantages, such as safety, comfort, high speed, large capacity and so on. Because of the high construction costs, its application has been limited.

Since the traction of linear motor driven railcar has nothing to do with the factor of adhension, the transportation system have a low noise and losses which come from wheel-rail friction. It is one of the development directions for urban rail transportation.

城市轨道交通具有安全、舒适、速度快、运量大的特点,但由于工程造价昂贵、工程量大、施工周期长、环境控制困难,在一定程度上限制了它的应用。采用线性电机驱动的轮轨车辆可有效降低车体高度,减小隧道断面面积,从而达到降低工程造价的目的。另外,线性电机的电磁力可直接作用于线路产生牵引力,牵引力不再受粘着系数限制,车辆爬坡能力强,选线自由度大,轮轨磨耗和噪声小,有利于采用高架线路结构。因此,采用线性电机驱动的轨道交通成为城市轨道交通的发展趋势之一。
