To reduce the energy density of the ballast cleaning machine drive, it is necessary to evaluate the load affecting the drive of the bar device, since it is the most loaded while cutting the ballast. To obtain and evaluate the drive parameters during operation, it is proposed to use computer modeling methods using software complexes. To form the initial data when modeling the drive, it is necessary to study the process of interaction of the ballast with the bar chain of the cutting tool, which will allow to find out the nature of cutting. According to LS-Dyna, it was possible to determine that the load during modeling is sinusoidal, which corresponds to the experimental studies conducted in this area. In addition, it was found that during the operation of the bar working body, cutting forces decrease when dragging the scraper sole along the ballast layer. The use of FestoHydrolic software made it possible to find a sinusoidal load affecting the drive of the cutting tool, and the amplitude of changes in its parameters is also evaluated.
