Abstract (English):
The article is devoted to the description of the creation of a computer model of the movement of a railway freight car along the section of the track adjacent to the rail joint. The model takes into account the elastic characteristics and ballast subsidence in the joint zone. The results of computer simulation are further used to solve the contact problem in the wheel-rail system. The study varied a number of parameters affecting this process of wheel movement. For the operating speeds of the freight car, the range of values of the dynamic forces arising between the wheel and the rail during the passage of the joint is determined.
