| The planning and construction of the passenger-freight shared railway of 200km/h in the arduous mountainous area on the plateau indicates that the railway is about to take shape as the main channel for goods in and out of the arduous mountainous area on the plateau.Railway cargo transportation will accelerate the overall development of the regional economy,and accelerate the integration of the arduous mountainous area on the plateau into the new pattern of national economic development.However,the harsh meteorological environment and complex terrain in the arduous mountainous area on the plateau not only bring great challenges to the construction of the railway,but also make it very difficult to organize the cargo transportation of the railway in the arduous mountainous area on the plateau and the safe operation of railway freight cars,especially in the passenger-freight shared railway with a design speed of 200km/h has different characteristics in the organization of cargo transportation.Based on the summary and combing ideas of relevant research,this research takes the arduous mountainous area on the plateau as the research background,combined with the development status of domestic and foreign railway freight transportation organizations.The main research contents are as follows:(1)Analyze the characteristics of the natural and industrial development in the arduous mountainous area on the plateau,dig deeper into the railway freight market,summarize the characteristics of the passenger-freight shared railway of 200km/h in the arduous mountainous area on the plateau indicates,and carry out the research on the freight transportation organization and the characteristics of vehicle demand based on this.(2)In terms of vehicle demand characteristics,combined with the foregoing summary of freight characteristics,recommendations for the selection of freight cars o the passengerfreight shared railway of 200km/h in the arduous mountainous area on the plateau indicates are put forward,using quantitative and qualitative analysis methods to study the railway braking performance and determine the selection of brake shoes finally,after clarifying the influence of the meteorological and slope conditions of the arduous mountainous area on the plateau on the vehicle operation process,the railway operation simulation model is constructed and an example calculation is carried out.(3)In terms of organization mode,firstly,it analyzes the difference between the marketoriented dynamic planning transportation organization mode and other transportation organizations.Based on the characteristics of vehicle demand and the characteristics of the passenger-freight shared railway of 200km/h in the arduous mountainous area on the plateau,the market-oriented dynamic planning transportation organization is studied.The feasibility and necessity of the model in the passenger-freight shared railway of 200km/h in the arduous mountainous area on the plateau;secondly,combined with modern logistics services and management concepts,the passenger-freight shared railway of 200km/h in the arduous mountainous area on the plateau market-oriented dynamic planning transportation organization mode is formed,and form service system;finally,based on modern logistics concepts,the product lineage design method was adopted to form a the passenger-freight shared railway of 200km/h in the arduous mountainous area on the plateau product system,and SPN was used to design and optimize the passenger-freight shared railway of 200km/h in the arduous mountainous area on the plateau.The process supports the development of the railway freight transportation organization model from two aspects: product design and process optimization. |
