摘要:
中车集团已推出新一代200 km/h级新型中速磁浮列车,但相应的线路技术标准未做系统性研究。本文利用SIMPACK软件建立车-线动力学模型,依据列车运行的舒适性、安全性评价指标,兼顾静力学计算结果,确定中速磁浮最小竖曲线半径,结果表明:(1)垂向加速度最大允许值决定最小竖曲线半径取值,且仿真分析结果较静力学计算结果大;(2)推荐凹型竖曲线最小半径在一般情况下取5 000 m,困难情况下取 4 000 m;(3)凸型竖曲线最小半径一般情况下取12 000 m,困难情况下取9 000 m。
Abstract:
CRRC has launched a new generation of 200 km/h class new medium-speed maglev train, but has not systematically studied the corresponding line technical standards. Based on SIMPACK software, a dynamic model of train-line is established, and the minimum radius of the vertical curve for medium-speed maglev is determined according to the comfort and safety evaluation index of train running and the static computation results. The results show that: (1) The maximum allowable value of vertical acceleration determines the minimum the radius of vertical curve, and the result of simulation analysis is larger than that of static computation. (2) It is recommended that the minimum radius of concave vertical curve should be 5 000 m in general and 4 000 m in difficult cases. (3) The minimum radius of convex vertical curve is 12 000 m in general, and 9 000 m in difficult cases.
