Бібліографічний опис: Effect of joint and isolated irregularities of the track on the wear of rails in curves / D. Potapov, S. Panchenko, Y. Leibuk, Yu.Tuley, P. Plis // MATEC Web of Conferences. - 2018. - Vol. 230 (01012). - Р. 1-5.
Короткий огляд (реферат): The purpose of the work is to identifying causes of intensive lateral wear of rails and other track failures in short radius curves using numerical methods. The study has been conducted for the most common type of rolling stock: four-axle freight cars on TsNII-Сh3 bogies, transportation of which makes 75-90% of freight load of the track sections. Thus, it is the effect of these cars which is the main cause of the above disorders. To solve the problem, effect of the following parameters of the track plan on dynamic processes of interaction of the track and rolling stock was investigated in the work: effect of the curves radius, the unbalanced accelerations and the width of the track; effect of local joint and smooth irregularities of the track in plan view. The results of numerical studies. A mathematical model of the spatial dynamic system “vehicle-track” has been used to perform the study, which is based on the design diagrams of the track in the form of long rail beams resting on multiple dissipative elastic supporting sleepers with nonlinear characteristics. This model is implemented in the MathCAD software system.
