ENSURING THE RELIABLE OPERATION OF AUTOMATIC COUPLING DEVICES IN THE PRESENCE OF TRACK GEOMETRIC IRREGULARITIES
Abstract and keywords
Abstract (English):
The growing need to ensure the safe operation of rolling stock makes it necessary to study the criteria that lead to failures and breakdowns both during operation and downtime. Ensuring trouble-free coupling of carriages is one of the top priority tasks on the railway. This concerns both the coupling of new carriages and the prevention of self-discoupling of rolling stock carriages. Due to the track imperfection, namely, the presence of curved sections both horizontally and vertically, it is likely that the axes of the auto-coupling devices will diverge. Despite the developed standards for the maintenance of railway tracks, the departure of the carriage overall dimensions is not always correctly assessed, which leads to irreparable consequences. The paper proposes a method to improve the reliability of the operation of automatic coupling devices by introducing guiding centering systems.
