CALCULATION BY NUMERICAL METHODS OF THERMALLY INDUCED STRESS IN AXISYMMETRICAL WHEELS: CONSIDERATIONS ON MEASUREMENT OF COEFFICIENT OF CONVECTION

With higher speeds and heavier loads, the effects of heat generated in braking on wheels is becoming more severe. This reports an analytical study of how the heat is propagated and the temperature gradient through the wheel, irrespective of its shape. A simple test on a scale model was used to determine the coefficient of convection for each part of the wheel. Once thermal gradients are known, stresses can be asssessed.
