摘要:

针对曲线段高速磁浮车-桥耦合问题,基于多体动力学理论与UM软件建立了列车模型,分析了曲线轨道梁参数对系统响应的影响,并提出车速与曲线半径的匹配方案。研究结果表明:400 km/h车速通过半径3000 m、横坡角12°曲线的车体横向加速度超限,需降速或增大半径;增大横坡角可抑制横向加速度但会增大垂向加速度;450 km/h通过6000 m半径曲线的各项响应均满足限值;横坡角不超过12°时,车速300 km/h、400 km/h对应的最小曲线半径分别为3000 m和6000 m;横坡角不超过9°时,车速450 km/h对应的最小曲线半径为9000 m。

Abstract:

For the high-speed maglev vehicle-bridge coupling problem on curved sections, a maglev train model was established based on the multi-body dynamics theory and UM software. The influence of curved guideway parameters on the system response was analyzed. A matching scheme of train speed and curve radius was proposed. The research results show that the lateral acceleration of the body exceeds the limit as it passes through a curve with a radius of 3000 m and a cross slope angle of 12° at the speed of 400 km/h, so the speed needs to be reduced or the radius needs to be increased; increasing the cross slope angle may suppress the lateral acceleration while increasing the vertical acceleration; all responses meet the limit requirements as it passes through the curve with the radius of 6000 m and the speed of 450 km/h; when the cross slope angle does not exceed 12°, the minimum curve radii of 3000 m and 6000 m correspond to train speeds of 300 km/h and 400 km/h, respectively; when the cross slope angle does not exceed 9°, the minimum curve radius is 9000 m corresponding to the speed of 450 km/h.

Key words: maglev train, vehicle-bridge coupling, radius of curve, cross slope angle
