摘　　要：为了精确掌握高速磁浮铁路车站列车作业过程及相应的设备使用状况,为车站设备能力分析、车站作业组织优化等提供依据,针对具备列车始发终到能力的高速磁浮铁路车站,基于离散事件仿真框架,结合高速磁浮铁路车站作业过程和要求,定义17类车站作业事件及其关联关系、车站状态属性,设计高速磁浮铁路车站作业仿真算法,对高速磁浮铁路尽端式车站的车站作业进行仿真。仿真结果表明,随着车站空线系数增大,相应的股道能力利用率普遍增大;始发终到列车占比和立折列车占比对车站股道及道岔利用率影响较高;所提出的仿真算法能够分析车站作业对车站相关设备利用率的影响。In order to accurately grasp the operation process of high-speed maglev railway station and the use of corresponding equipment,and provide the basis for the analysis of station equipment capacity and the optimization of station operation organization,based on the discrete event simulation framework,for the high-speed maglev railway station with the ability of train departure and arrival,this paper combined with the station operation process and requirements of high-speed maglev railway,defined 17 kinds of station operation events and their relationship,station state attributes,designed the simulation algorithm of the station operation for the high-speed maglev railway,and simulate the station operation for the end station of high-speed maglev railway.The simulation results show that with the increase of the station empty line coefficient,the utilization rate of the corresponding track capacity generally increases,the proportion of departure and arrival trains and the proportion of vertical folding trains have a higher impact on the utilization rate of station tracks and turnouts.The proposed simulation algorithm can analyze the influence of station operation on the utilization rate of station related equipment.
