摘　　要：合理的限界设计,不仅能为磁浮提供安全的行车环境,还能减少空间浪费,以及降低线路施工成本。结合常导长定子高速磁浮自身结构特点,详细地阐述了限界的计算方法及其所计及的要素。将限界计算的各技术参数分为车辆和轨道两大类,并将各技术参数按概率性质的不同进行分类叠加。在分析曲线段加宽时,使用动力学分析软件Simpack建立常导长定子高速磁浮动力学仿真模型,分析得到相应曲线段几何偏移引起的限界加宽量,通过公式计算得到超高或欠超高引起的加宽量,将两部分进行线性叠加。通过计算,得出高速磁浮在曲线半径为650 m的限界图,以及各限界的控制点坐标值,得出在半径650 m的曲线上非空气动力作用设备限界顶部距滑行轨面3 655 mm,底部距滑行轨面1 000 mm,宽4 240 mm为宜,可为高速磁浮工程化提供参考。Reasonable design of gauges not only provides operating safety of maglev train, but also reduces the waste on space and the cost of track construction. Based on the characteristics of routine conductive long stator high-speed maglev, this paper thoroughly expounds the calculating method of gauges and the essential factors involved, and also divides technical parameters of gauge calculation into two categories of vehicle and track. The paper makes an overlay analysis of the technical parameters by considering the difference of probabilistic nature. In the analysis of the curve widening, this paper establishes the simulation model of routine conductive long stator high-speed maglev by using dynamic analysis software, analyzes widening values of gauges caused by geometric offset of curve segment, and also carries out superposition calculation of widening value due to superelevation and deficient superelevation. By this calculation, the 650 m-radius gauge diagram of high-speed maglev and control point coordinate are given. It is concluded that the distance from the top of non-aerodynamic equipment gauge to sliding rail surface should be 3 655 mm, the distance from bottom to sliding rail surface should be 1 000 mm, and the width of the gauge should be 4 240 mm on 650 m-radius curve. The results of the paper provide some references for the project of high-speed maglev.
