The distribution of residual stresses in railroad wheels after electrocontact strengthening of the rolling surface

摘要

A procedure for the quality control of residual stresses in the rims of rolled wheels and locomotive tires via the ultrasound method using electromagnetic-acoustic excitation-reception of elastic waves is described. The results of the determination of residual stresses in surface-strengthened rims and pressed-on tires prior to strengthening and after electrocontact strengthening of the rolling surface of wheels are given.
