Study and Monitoring of Driving Forces that Arise at the Contact Point Between the Wheel Border and the Rail during the Motion of the Rail Vehicle on a Curved Path of the Railway Line

One of the most acute problems faced today by Railway Transport Companies is the rapid wear of locomotive wheel borders in the freight transport. Hence, the purpose of this article is to find ways to reduce the forces acting on the wheels of railway vehicles, generally during their movement in small radius turns. For means of simplification has been assumed that the train is moving at uniform speed during a curved path. Analyzing the scheme of action of forces on the pair of wheels, we see that one of the ways to reduce this consumption phenomenon is to reduce the parasitic moment of frictional forces. With reference to the practice of roller-contact studies, we modeled mathematically the redistribution of frictional forces at the point of contact of the wheel – rail pair and realized two computer models for two variants of wheel profiles: conical and curved.   Received: 23 September 2022 / Accepted: 28 November 2022 / Published: 20 December 2022
