К вопросу взаимодействия подвижного состава и геометрических параметров трассы высокоскоростных железнодорожных магистралей

Abstract

Objective: Due to the lack of global experience of holding on one track high-speed passenger trains (moving at a speed up to 400 km/h), high-speed passenger trains (moving at a speed up to 250 km/h) and special freight trains (accelerating to a speed of more than 200 km/h), the only possible way of studying the influence of a train on a track is computer simulation modeling. The analysis of the existing computer programs was carried out and the most effective programme for the solution of combined train movement was selected. Methods: Simulation modeling was applied. On the basis of the obtained model the possibility of “Universal mechanism” software practical application was considered. Results: A test simulation model of a high-speed train carriage was developed in “Universal mechanism” software application. Preliminary results showed the possibility of its usage for the study of a high-speed train and track interaction. Practical importance: Modern computer technologies make it possible to solve the tasks of dynamic interaction with a high degree of accuracy. Among the variety of software used for the study of dynamic behavior of a railway vehicle in Russia, “Universal mechanism” software application is of wide popularity and may be used for the study of dynamic behavior of different types of trains on railway tracks of different plans and profiles.
