Abstract

The paper presents the research results of cuts braking modes in hump yards.

The objective of this paper is developing the methods for assessment of braking modes of cuts under conditions of fuzziness of their rolling properties, as well as selecting the admissible starting speed range of cuts from brake positions.

As a criterion for assessing the modes of target control of cut rolling speed, it was proposed to use an average window size on a sorting track at the established norms of probable exceeding of admissible speed of wagons at their collision and stop in retarders.

As a criterion for evaluating the modes of a cut rolling speed interval control, using the risk of their non-division on the railway points was proposed.

Using the simulation modeling and mathematical statistics, the configuration of admissible starting speed range of cuts from brake positions has been set.

The scope of this range is 76.7% of admissible starting speed range of cuts from brake positions with respect to target braking terms.

The conducted tests allow simplifying the choice of cut braking modes in systems of automatic control of their rolling speed
