Simulation Of Heavy-Loaded Transportation Organization And Train Diagram Of Freight Railway Line

Heavy-loaded freight is one direction of railway in our country. In the short period, our country, "North south of coal, coal East West tune" the basic structure of "north coal carrying south, west coal carrying east" will not change, providing advantage conditions for heavy-loaded railway development. With the comprehensive construction of passenger special line, it provides advantage conditions for heavy-loaded railway transportation. The heavy-loaded train can be run on busy railway line.Based on the analysis of study status of heavy-loaded transportation technology at home and abroad, achievements of heavy-loaded railway transportation and the existing problem of heavy-loaded railway transportation, for improvement demand of Da-Qin railway transportation, the project of 400 millions tons transportations organization is put forward, and the train diagram of combined heavy-loaded train is simulated. Based on automatic block of 4-aspect, the cellular automaton model that is same with railway system is put forward.The contents of paper are as follows:(1) The influences of railway line, train traction, rail vehicles, power supply system, transport organization, loading capacity, and unloading ability factors on transport capacity of heavy-loaded railway is analyzed. The factors that must be matched with each other and optimizing combination impact on heavy-loaded transport system are many aspects.(2) The classification of heavy-loaded transport organization including the heavy-loaded unit trains, heavy-loaded combined train, heavy-loaded full train and the implicated conditions are introduced. The concrete organization advantages of heavy-loaded unit trains are analyzed. Heavy-loaded unit train organization is implicated in the Da-Qin line, playing an important role in improvement of transport capacity of heavy-loaded railway in my country.(3) At present, the instance of Da-Qin railway transport organizations including the Da-Qin railway general situation, the transport organization characteristic of Da-Qin railway and heavy-loaded railway, the status of Da-Qin railway, the characteristics of transport organization is analyzed. It is necessary to expand the transport capacity of the Da-Qin railway by the analysis of the status of coal transport volume and the forecast volume in the Da-Qin railway. The Da-Qin line 400 millions tons transport organizations including reasonable train plan, the analysis of 20,000 tons heavy-loaded train transport mode, the calculation of capacity of mixed program, the mode of Da-Qin line 400 millions tons capacity expansion, the transport organization to be adopted, the calculation of capacity is analyzed. It provides basis for the capacity expansion of Da-Qin railway. (4) The paper put forward the cellular automaton model based on automatic block of 4-aspect and the train diagram of combined heavy-loaded train is simulated-for example of Da-Qin railway. The relation between the proportions of different trains, the middle Station, the trains track, and railway transportation capacity is analyzed.The thesis gives the research on the mode of Da-qin railway transportation organization. The research results of the thesis can be used in the extension and development of heavy-loaded transportation in our country as the reference and is help to format heavy-loaded transportation system in our country. It is very significance to the development of heavy-loaded transportation. It is very significance to expansion and application of automatic block system through the analysis of modeling and the simulation results, and theoretical and practical value on improving the railway transport capacity. In addition, the modeling of the rail transport system through the cellular automata theory has made promotion of simulation efficiency and the real response of simulation to real-world. It is significance to the promotion of construction of comprehensive traffic flow simulation and evaluation of the software platform.
