Abstract
In the design of railroad wheels compliant with State Standard GOST 10791–2011, optimal selection of the disk and its dimensions remains a problem. Calculations for wheels based on curvilinear disks with a central camber show that the stress in the disks significantly exceeds the yield point of wheel steels. The replacement of the flat conical part of the disk with a curvilinear section based on a catenary curve reduces the stress in the disk, ensures a more uniform stress distribution, and results in a more competitive product.
