Research On The Speed Match And Number Match Of The Co-running High-speed Trains And EDU Trains On The High-speed Railway

Recently in our country,most of the high-speed railways have been under construction,which have not formed a network,and for the high-speed railways,because its transport mode includes the high-speed trains and the medium-speed trains,which lays a requirement for their speeds and numbers,in response,this thesis will make a study of the speed match between high-speed trains and the medium speed trains,as well as the number match between them,it will improve the segment through capacity,reduce the number of locomotives,and ensure the running quality of the two kinds of trains.Firstly,together with the statements of the through capacity of high-speed railways which contain the high-speed and medium-speed trains,the thesis will make an analysi s of the factors influencing the through capacity. With the analysis of different conditio n under which medium-speed trains will be overtaken,the paper will make a thorough study of the deduction coefficient.Secondly,the thesis will make an analysis of overtaking station distances,to be spe cefic,in eyes of through capacity,deduction coeffcient balance,departure interval,the distan ces between overtaking stations will be quantified.At the same time,from the perspectiv e of train control system and the minimum curve radius of high-speed railways,some r equirements have been made.In the end,with an analysis on how the speed difference factors in the overtakin g station distance,travel speed factor and deduction coefficent of medium-speed trains,th e final speed difference will be concluded,then,for two kinds of trains with the specific speeds,the paper will make an anaysis on the train number match factor in the travel speed,and deduction coefficient of medium-speed trains,as well as the segment throug h capacity.Finnally,the number match alternatives of high-speed train and medium-speed train,with specific speed matches,will be drawn.
