Title:Comparison of thermal stress developed in s plate straight plate and deep dish wheels
Author(s):Wetenkamp, H. R.
Abstract:Heating of the rim of a wheel by brake shoes causes a deformation of the wheel which can result in an axial movement of the rim of the wheel relative to the hub of the wheel and a change in the size of the wheel hub. Five different design wheels were examined by subjecting the wheels to braking cycles in a railway wheel dynamometer. The five design wheels were further examined by a theoretical analysis which permitted the determination of displacements and stresses developed in the wheels by given thermal loads. The results indicate the two “S” plate wheels experienced little axial rim movement compared to the deep dish design wheel. However, the stresses developed in the “S” plate wheels were substantially higher than those determined in the other wheels. The straight plate wheels also developed larger and less desirable types of stresses than the deep dish wheel. The “S” plate wheels and the offset straight plate wheel all tightened on their axels after testing. It is believed that the “S” plate and straight plate wheels as herein examined are not desirable designs.
