THERMAL STRESS DEVELOPED IN S PLATE, STRAIGHT PLATE, AND DEEP DISH WHEELS

Heating of the rim of a railway car wheel by brake shoes can result in axial movement of the rim of the wheel and a change in hub diameter. Five-wheel designs were examined by theoretical analysis and compared with some experimental results obtained from subjecting the wheels to braking cycles on the dynamometer. Specific values of elastic stress developed by a given thermal load are presented so that direct comparison between wheel designs is possible.
