Permissible Values of the Dynamic Impact of the Rolling Stock on the Railway Track in the Case of Axle Load Increase

Purpose. The study is aimed at determining experimentally the values of parameters characterizing dynamic effect rolling stock on railway track, substantiating maximum permissible (limiting) values. Methodology. To investigate interaction between track and stock, devices to record various physical processes were installed experimental sections. in 8 sections along outer line. establish actual state field measurements carried out accordance with Program research methodology. Findings. According results tests impact it was revealed that average vertical loads, and, accordingly, deformations, under cars an axle load up 25 tf/axle are higher than 23.5 by percent. loads exceeded 10.0 tf, 12.8 tf. During tests, no found which force exceeds 20 horizontal 10 Therefore, norms can be taken Regulations Preventive Maintenance Repair Track Work Railways Ukraine. Originality. authors conducted a assess characteristics particular stresses edges rail base, forces from wheels stock. Practical value. On basis obtained, possible estimate substantiate need change standards for material consumption superstructure labor. In turn, this will make plan repair periods more economically according indicators superstructure.
