Abstract

The goal of the research is to study the impact of the release speed accuracy of set of cars from the yard retarder position on the filling quality of the hump yards. The developed simulation model for filling the sorting tracks, which is based on the calculating the speed of the zcars, was implemented for the study. The object of research is the accuracy of the devices for setting the release speed of set of cars to the railway. The subject is the error impact on the quality of filling the tracks of the hump yards. The normative profile was chosen. As a result of the study, it was revealed that the average collision speed of cars does not depend on the error of the devices. An error increase affects the sizes of gaps. An error increase leads to a decrease in the use factor of the useful railway length in the sorting yard, as well as to an increase in the number of backings necessary for the accumulation of one train. The obtained results can be used to justify the need for improving the operation accuracy of devices for controlling the release speed of sets of cars.
