Determination of the Vertical Load on the Carrying Structure of a Flat Wagon with the 18–100 and Y25 Bogies

The study deals with determination of the vertical load on carrying structure a flat wagon 18–100 and Y25 bogies using mathematic modelling. was made for an empty passing over joint irregularity. authors calculated designed parameters actual features recorded during field tests. mathematical model solved in MathCad software. found that application bogie can decrease dynamic by 41.1% comparison to bogie. Therefore, under allows decreasing loading 41.4% also looks at service life supporting bogie, which be more than twice as long research interest specialists concerned improvements characteristics fatigue strength freight cars, safe rail operation, security, results used development innovative structures.
