摘　　要：为研究中低速磁浮交通车辆在道岔区的设备限界,结合中低速磁浮车辆及道岔的结构特点,提出宽体和窄体两种简化计算模型。经分析探讨,仅将中低速磁浮车辆直线段设备限界和车辆在道岔区的几何偏移量作为道岔区设备限界计算的计及因素;采用MATLAB计算验证并对比计算结果,两种简化模型的设备限界计算结果在道岔不同部位存在11 mm以内的差异,其中宽体模型的计算结果更为准确。在工程应用条件下,两种计算方法对于工程方案及造价影响不大,均可保证列车在道岔区的行车安全。In order to study the equipment gauge in turnout area for medium and low-speed maglev vehicle,two simplified calculation models—wide model and narrow model are proposed based on the structural characteristics of medium and low・speed maglev vehicle and turnouts.After analysis,only the equipment gauge of the straight line section and the geometric offset in the turnout area are taken into account in the calculation of the equipment gauge in turnout area of medium and low-speed maglev vehicle.Using MATLAB to verify and compare the calculation results,the difference between the two simplified models is within 11 mm in different parts of the turnout.The calculation of the wide-body model is more accurate.Under the condition of engineering application,the two calculation methods have little effect on the project plan and cost,and can ensure the safety of train running in the turnout area.
