Abstract

The train traction calculation tasks are to be determining the train mass, testing the train mass, determining the running time and establishing the train operation chart in sections, and so on. To determine the running time and to establish the train operation chart in sections, first of all, it is necessary to determine and establish the resultant force and the unit resultant force of trains in operation. The trains operating on railways are quite diverse, because many different types of locomotives are used for different masses of trains. The determination of the running time and the train operation chart, including the unit resultant force, must be done for each specific train, resulting in a huge amount of computation that takes a long time when calculating by the traditional method. Therefore, it is necessary to develop a general calculation program to solve the problem quickly and accurately. The general program includes some basic modules corresponding to the above tasks. The article presents the process of developing a program to calculate and to establish the unit resultant force curves for trains with locomotives and wagons Railways used in Vietnam as a module in the mentioned general program.
