IMPROVEMENT OF QUASI-CONTINUOUS SPEED CONTROL SYSTEM OF CUTS ON THE SORTING TRACKS

Abstract

Purpose. . The aim of the work is to propose options for improving the quasi-continuous speed control system of cuts on the sorting tracks and to search for a rational combination of system parameters to determine the potential possibilities of each improvement option. Methodology. The research was carried out on the basis of an analysis of the results of simulation modeling of the filling process for sorting tracks with cars, which are equipped with a quasi-continuous speed control system of cuts. In order to achieve the best quality indicators for filling the sorting track with cars, the parameters of the quasi-continuous speed control system of cuts were varied. As a result, the obtained simulation results for the options were analyzed and compared with each other and with the base option. Findings. In the work, the basic option is a quasi-continuous speed control system of cuts on the sorting tracks, equipped with uncontrolled point wagon retarders and two fundamentally different options for improving the system are proposed in order to improve the quality indicators of filling the sorting ways with cars: 1) to use uncontrolled point car accelerators-retarders instead of uncontrolled point wagon retarders in the system as point wagon speed controllers; 2) to introduce control of point wagon retarders in the system. The first option of improving the system as compared with the basic option can provide an improvement in the degree of filling of the sorting tracks with cars by 1.5% for a half as much slope and half as many point controllers for the speed of cars. The second option of improving the system as compared with the basic one provides the same quality indicators of filling the sorting tracks with cars on a smaller slope of the sorting track and with a smaller number of point speed controllers by 5-10o%.Practical value. The results of the study can be used in the case of the introduction of a quasi-continuous speed control system of cuts оn the sorting tracks of yards.
