МАТЕМАТИЧЕСКАЯ МОДЕЛЬ ЖЕЛЕЗНОДОРОЖНОГО ПОДВИЖНОГО СОСТАВА С УПРУГОДЕФОРМИРУЕМЫМИ АВТОСЦЕПНЫМИ УСТРОЙСТВАМИ В НАЧАЛЬНЫЙ МОМЕНТ ДВИЖЕНИЯ

Abstract

The paper presents a mathematical model of movement start of railway rolling stock with elastic automatic couplers. It shows that starting of a heavy-loaded train equipped with elastically deformed automatic couplers occurs significantly easier in comparison with non-deformable ones, and the more cars are in the train, the higher this advantage is. Essentially, it is stipulated by the substitution of simultaneous start of cars movement on alternating. In order to exclude longitudinal fluctuations of the train after reaching maximal stretch of the automatic coupler it is necessary to block the possibility of the harmonic compression mechanically.
