PROBLEMS OF REGULATION ON SPEED ROLLING OF CUTS ON THE SORTING HUMP

Abstract

Purpose. Marshalling yards are strong points for the organization of wagonflows on the railway network of Ukraine; on their quality of work depends largely on the implementation of deliveries, the preservation of wagons and cargo, reducing transportation costs. The most efficient sorter at such stations are sorting humps. Systems of the interval and aiming adjusting of speed of rolling of cuts on the sorting humps semi-dominant chili spread of the railways in the world. One disadvantage of such systems is damaged wagons during sorting. Identifying ways to eliminate this disadvantage is an urgent task. Methodology . For the average speed collision of cuts on the sorting tracks to use simulations disbandment process breaking-up of trains on the sorting hump. Findings. It was found that the decrease in the estimated speed approach to cuts the wagons, located on sorting tracks, causes a significant decrease in the number of possible damaged cars for 1000 processed on the hump and a decrease in annual operating costs associated with damage to the wagons. Increase of error of braking of cuts causes a significant increase in the number of such wagons. Increase slope sorting tracks cause a certain increase in the number of wagons damaged and costs related to their injury. Originality. The influence of the accuracy of the braking of cuts at the park brake position, the design speed of their approach to wagons located on sorting ways and profile settings of these tracks on the average speed of the collision of cuts and the possible number of damaged wagons. Practical value. The results allow to determine the most rational option sorting hump technical equipment and control systems park brake position.
