Purpose: Determination of the minimum allowable thickness of the rim of solid-rolled wheels of freight cars depending on the design and axial load. Methods: Methods of elasticity theory, methods of numerical solution of partial differential equations (finite element method) are used. Results: The minimum allowable thicknesses of the rims of solid-rolled wheels of freight cars have been determined, as well as the values of fatigue resistance factors for wheels manufactured according to drawing 13.45.1043-01A, 13.45.1011-143, 13.45.1399-207 with a rim thickness of 30 to 16 mm and various axial load. The calculations showed that for the wheels manufactured according to drawing 13.45.1043-01A, 13.45.1399-207, the minimum permissible rim thickness can be reduced to 16 mm. Practical significance: The dependence of the fatigue resistance coefficient on the rim thickness and axial load with an accuracy of up to 15% is obtained, as well as certain minimum permissible thicknesses of the rims of solid-rolled wheels will increase their service life.
