摘要 研究目的：线间距是确定线路选线的重要参数,受磁浮列车基本建筑限界、列车交会压力波和车辆动力学性能等因素影响。本文基于600 km/h高速磁浮超导电动悬浮研究需求,参考高速磁浮、高速铁路系统研究成果,从空气动力学性能、安全空间、磁场波动及工程造价等方面,展开针对超导电动悬浮线间距的研究并给出线间距参数建议值。
研究结论：（1）基于空气动力学的数值模拟仿真分析得出,在明线段对车体表面交会压力波/气动力的影响大于隧道内交会的影响;（2）线间距5.4~6.0 m对应会车列车横移量均小于U形梁侧壁导向间隙64 mm,满足侧壁导向间隙要求;（3）线间距5.8 m更有利于节省工程投资及降低车辆造价,并满足超导磁体运动磁场波动分布要求; (4)本研究成果可为高速磁浮项目工程线路设计提供参考。

Abstract：Research purposes: Line spacing is an important parameter for route selection, which is affected by the basic building limit of maglev train, train rendezvous pressure wave, vehicle dynamic performance and other factors. Based on the research requirements of 600 km/h high-speed maglev superconducting electric levitation, and referring to the research results of high-speed maglev and high-speed railway system, this paper studies the line spacing of superconducting electric levitation from the aspects of aerodynamic performance, safe space, magnetic field fluctuation and engineering cost, and gives the suggested values of line spacing parameters.
Research conclusions: (1) Numerical simulation analysis based on aerodynamics: the influence on the pressure wave/aerodynamic force of the car body surface rendezvous in the open line section is greater than that in the tunnel. (2) The train transverse displacement corresponding to the line spacing of 5.4 m to 6.0 m is less than the U beam sidewall guide clearance 64 mm, which meets the requirements of the sidewall guide clearance. (3) The line spacing of 5.8 m is more beneficial to save engineering investment and reduce vehicle cost, and to meet the requirements of magnetic field fluctuation distribution of superconducting magnets. (4) The research results can be applied to the line design of high-speed maglev project

Key words： high-speed maglev superconducting electric levitation aerodynamics line spacing
