Effect of shape and diameter on temperature limit and residual stress under thermally overloaded conditions of tread braked wheels

Abstract

A series of elastic-plastic FE analyses was carried out to identify the allowable operating temperature of wheels of different diameter with various web shapes. The allowable temperature was determined by the onset temperature of plastic deformation during temperature rise. Circumferential tensile residual stress and residual rim displacement were generated depending on the degree of constraint of displacement, i.e. the shape of the web. The analytical results were in close agreement with the experimental values in the literature.
