THE WHEEL STRESS-STRAIN ANALYSIS AFTER HEAT TREATMENT USING THE THEORY OF ELASTICITY
Abstract (English):
The paper is devoted to modeling the stress-strain state of a car wheel in the case of its heat treatment. The calculation technique is based on the application of the finite element method for a specialized design diagram. The final elements have the form of rings of triangular cross-section. The initial equations are used on the basis of the theory of elasticity. The approximation of movements along the axis of rotation and along the radius is linear, in the circumferential direction it has the form of trigonometric series. Using the proposed technique, calculations of a wheel with two variants of rim hardening are implemented: as one annular strip on the rolling surface and with the use of two additional strips with an intermediate degree of hardening. The developed means of modeling can be used to develop methods and to select wheel hardening parameters.
