Dorosh A. The efficiency increase of train breaking-up process at the humps by the improvement of cuts braking modes determination methods

The thesis purpose is the efficiency and quality increase of sorting process at the stations by the improvement of cuts braking modes determination. The research object is the trains breaking-up process. The scientific problem was solved with the correct use of modern mathematics. Scientific novelty is as follows: For the first time was performed the comprehensive evaluation of influence of hump neck design on sorting process efficiency; was improved optimization problem of braking mode controlled cut of the designed group; was improved the simulation model of the train breaking-up process at the automated humps; was improved the iteration method for optimizing the braking modes of train cuts. The Improvement of the train braking-up process simulation model at humps allows to evaluate the effect of retarders control parameters on the sorting process performance. Accounting of the adjacent cuts separation at the retarders allows to exclude cases of non-separation on the retarders positions of the hump rolling-down part. Received influence of hump necks construction on the sorting process performance made it possible to formulate recommendations of the hump neck choice for further automation. The results were used for DNURT scientific research and educational process. The work practical implementation is confirmed by relevant documents listed at the thesis annexes.
