Complex stress state of rim in the contact zone between wheel and rail varies depending of vehicle exploatation regime. Wheel load and inertia force produce normal stresses, and shear stress is alsooccured in contact zone at starting and braking.Thermal stresses at braking produce changes in structure, deformation and tribological effects on wheel wreath. This paper analyzes these influences and derives analitical equations for state of strees which quantify these influences.
