AN IMPROVED METHOD FOR MEASURING THE RESIDUAL STRESSES IN RAILROAD SOLID WHEELS

These residual stresses are those resulting in particular from heating due to braking applied to the running surface of the wheel. The suggested measurement method admits that stresses in the wheel have two possible causes: a stress due to rim/plate interaction; a residual stress which remains in the plate after its separation from the rim. It stems from this analysis. Once strain gauges have been placed: the plate is cut by a lathe out of the wheel; the rim is sawn; and opening displacements are estimated by a simple elastic stress calculation. Diagrams and tables give the results of tests carried out on three types of wheel.
