Research On The Simulation Model Of High-Speed Trains' Private Yard Under The Condition Of Introducing The Passenger-Dedicated Line Into Existing Station

At present, the construction of China's passenger-dedicated line has been comprehensively carried out. How to properly assess the various construction programs that have introduced the passenger-dedicated line into the cities or railway terminals is a problem of practical importance. The method of introducing the passenger-dedicated line into the existing railway stations is frequently applies. In this mode, how to design the station layout and that of the railway terminals which have introduced the passenger-dedicated lines, as well as how to formulate the organizing methods of train operation in the railway station, are considered as a complex systematic project, which involves a series of interrelated factors.This paper briefly introduces the transportation organization mode of passenger-dedicated line and the facilities at the passenger station. In accordance with the existing construction modes which are introduced into the passenger-dedicated line, it briefly analyzes several station layouts. Meanwhile, this thesis introduces the factors that should be considered while deciding how to assign the tasks between the two yards. Last but not least, the paper focuses on analyzing the juxtaposed station layout that is adopted at the high-speed trains' private yard and medium-normal speed trains' private yard.In order to properly describe the operation system of the passenger station as well as the mathematical logical relations between the state variables and operating parameters, and to indicate the temporal and spatial relations among different operation events, this thesis firstly explains the types of trains applied in the high-speed and the medium-normal-speed yards. It also systematically analyzes the operation at the passenger station.Given the definite task-assigning programs and the definite train-organizing methods, this paper, in applying the technical standards adopted by two adjacent stations, especially explains how to build simulation operation models of the high-speed trains' private yard operation system. Such efforts have provided preliminary preparation for calculating the carrying capacity of the station at the peak times, which has important reference value in practical designing work and the train organization. Furthermore, based on such principles as whether it is convenient for passengers to walk or not, whether the equipment is efficiently utilized and whether it is up to the optimal train diagram between the adjacent sections, this article tries to preliminarily discuss how to apply the simulating results to regulate the arrival sequences of the trains, the plans of trains' crossing and overtaking as well as the schedule of the train dispatch by human computer interaction, as well as the principles of arranging train and shunting routs.
