Abstract

In the highly competitive market of transport services, there is a need to find new ways to improve the power efficiency of sorting process. The analysis of the current methods of technical and economic comparison of design options and the hardware rigging of sorting devices showed that the cost of car retarders makes up the largest portion of operating costs, which accompany the sorting process.
The article studies the extent to which the profile of a sorting yard influences on the required power of brake positions. It was found that in contrast to the required power of brake positions of the drain part, the required power of the park brake position additionally depends on the slope of the switch zone. The results of the studies show that the dependence is very low and it varies between 1.9 - 5.8%.
Thus, it is recommended during the optimization of design parameters at first approximation of the slope of the switch zone to take as a maximum (2 ‰). This will reduce the height of the profile from the top of the yard to the start of the switch zone and, consequently, the required power of the brake positions of the drain part. In addition, it will increase the path length of a rated runner.
These results allow us to offer a criterion of optimization of design parameters of the sorting yards and to use the required rated power of brake positions of the drain part that will reduce energy costs of the sorting process
