[Abstract]:With the rapid development of economy, the continuous improvement of people's life and the increasing demand for railway transportation, the Ministry of Railways has put forward a leapfrog development strategy to meet the needs of the development of national economy and market economy. On the existing lines, the capacity expansion and speed increase are carried out on a large scale and the passenger dedicated railway is built, and the existing train organization mode is improved, the equipment level is raised, and the value of the annual freight volume of passenger trains is affected. Under this background, this paper studies the commutation value of annual freight volume of passenger train, and provides reference for the revision of line rules. Based on the analysis of two factors, the deduction coefficient of passenger train and the traction quality of freight train, this paper calculates the value of the annual freight volume of passenger train. Firstly, through the analysis and research on the quality of freight train traction, the traction quality of different types of freight train is obtained under different slope limiting conditions. Based on the comparison between the actual traction quality and the theoretical traction quality of the "harmonious" freight locomotive, the method of calculating the traction mass by using the adhesive traction force is put forward. Secondly, through the analysis and study of the main factors affecting the passenger train deduction coefficient, the calculation method and the value of the passenger train deduction coefficient under different train organization modes are obtained by using the graphic method. The change rule of passenger train deduction coefficient is put forward, which provides a certain theoretical basis for rational arrangement of train running organization. Finally, the randsample function in MATLAB software is used to deal with the data of the net load of freight train traction and the deduction coefficient of passenger train, and then the value of the annual volume of passenger train is obtained. It is suggested that the gauge value is 1.5 Mt, which can provide a quantitative reference for the classification of railway grades and the determination of the number of main lines. To sum up, through the analysis and research on the quality of freight train traction, this paper obtains the traction quality of different types of freight train under different slope limiting conditions. This paper analyzes and summarizes the calculation method of passenger train deduction coefficient under different train organization modes, and calculates the annual volume of passenger train by using randsample function.
