China aims to build a strong transportation network,and proposes to strengthen the research and development of high-speed maglev system technology.High-speed maglev is as a high-speed,high-speed comfortable and convenient public transportation has gradually attracted more attention.Based on the transportation organization requirements of high-speed maglev train,this thesis analyzes the train operation optimization and capacity problems of the high-speed maglev station through the operation calculation of the high-speed maglev train.The research work of this thesis is studied as follows:(1)Based on the uniform mass model of train length,considering the actual length of the train and the speed limit conditions of the station,and taking the shortest time consumption of the train in the station as the optimization objective,the optimal model of single high-speed maglev train operation according to the fastest strategy was constructed.Besides,the speed conversion algorithm of "low speed – high speed" and "high speed-low-speed" sub-sections based on the conversion of train operation curve is proposed to solve the model effectively.The train running time of each operation in the station and the train routes under the station division sections are obtained,and the single train operation capacity of high-speed maglev station is analyzed.(2)Based on the time consumption of a single operation of high-speed maglev train in the high-speed maglev station,taking the occupation of train station routes and the cross-unwinding of various operations as constraints,considering the train occupation time,train delay time and the balance of arrival and departure line utilization as optimization objective,an optimization model of high-speed maglev station operation schedule under a given timetable is established.According to the characteristics of the problem,a genetic simulated annealing algorithm with the logical fitness function of station operation is designed.Based on a numerical example of high-speed maglev station,the optimal scheme of station operation arrangement under the condition that the total delay of highspeed maglev train is 0 s is obtained,and the capacity utilization of station is analyzed.(3)According to the influencing factors of the passing capacity of the high-speed maglev station,the influence of different transportation demand scenarios on the passing capacity of the high-speed maglev station is analyzed.A heuristic algorithm for station capacity based on arrangement compact of train operations is designed.Though comparative analyzing the high-speed maglev station passing capacity,passing capacity utilization rate of station lines and switches under different traffic flow composition types and proportions,it is concluded that the utilization efficiency of the passing capacity of the high-speed maglev station is decreased in order of through train,arrival and departure train,through train with stop,turn-back train.The result can be used as a reference for the operation arrangement and capacity utilization of high-speed maglev stations.There are 45 figures,38 tables and 88 references in this thesis.
