Аналіз розвитку теорій розрахунків залізничних колій

Abstract

UA: У статті виконано аналіз наукового внеску відомих залізничних науковців у період з 1835 року до теперішнього часу, які поповнили розвиток розрахунків взаємодії колеса рухомого складу на колію та на верхню будову колії для визначення оптимальних експлуатаційних характеристик.

EN: In this paper the analysis of scientific contribution, known Railways governmental scientists, in the development of calculations of the interaction of the wheels of the rolling stock on the railway track and track structure to determine the optimum operating characteristics in the period from 1835 to the present. It is concluded that the most common currently is the General design scheme of the way in the form of a beam-rail constant cross section, which relies on a continuous elastic Foundation. This diagram assumes the constancy of the elastic and dissipative characteristics of this reason. According to some authors, these assumptions are unfathomably idealized path and its technical condition. For conditions of non-public roads of the developed model and methods, which are based on the spatial scheme of the way in the form of beams-rails based on discrete elastic-dissipative supports sleepers. These models and methods allow in contrast to the known to consider not only the discreteness of Pirani rails on sleepers, but also the nonlinearity of the elastic-dissipative characteristics of the rail supports, and the differences of these characteristics for each foot.
