ON THE MOVEMENT OF A WAGON ALONG THE ENTIRE LENGTH OF A MARSHALLING HUMP UNDER TAILWIND CONDITIONS
Abstract
The article presents the results of studies varying the slopes of speed sections and the power of brake positions of the marshalling hump under the influence of tailwind force. In the brake position sections, the loaded wagon performs translational motion. Unlike existing hump calculation methods, the mass of the loaded wagon in the brake position sections should be determined without accounting for the inertia of rotating masses. A significant discrepancy is established in the values of the average time of wagon movement along the entire track profile, determined according to the Technical Operation Rules, compared to the wagon movement time calculated by the elementary physics formula. For the accepted initial data, the rational approach is maximum braking on all brake position sections, ensuring compliance with the permissible collision speeds established by the Technical Operation Rules.
