Analysis of the movement of an empty railcar on the longitudinal profile of the sorting slide

Abstract

The article uses analytical formulas derived from the application of the basic law of dynamics for non-ideal connections (the Dalembert principle), the calculation of the kinematic parameters of the rail carriage movement (acceleration, time, braking path) in the braking zone on the site of the first braking position of the sorting slide is performed. All over the world, it is becoming increasingly important to design and build modern sorting stations, as well as to choose the right height for sorting slides. The main function of the sorting slide at railway stations is the disbanding of trains, as well as the formation of new trains. Sorting will depend on how rationally the profile of the descending part of the slide is designed. Calculation of the height of the descending part of the slide and design work is carried out according to the existing method, according to which the movement of the railcar on the slope of the sorting slide, the speed is determined by the expression of the rate of fall of the railcar vertically, taking into account the inertia of the rotating masses. This, in turn, creates several problems. In developed countries, including the US, Germany, Sweden, China, India, and Russia much attention is paid to the development of methods, such as mechanization and automation of sorting ways of stations that affect haul transport and local rail network [1-7].
