Evaluation of Residual Stresses in Rims of Wagon Wheels Using the Electromagnetic–Acoustic Method

摘要

A technique for testing residual stresses in the rims of solid-rolled wagon wheels with an ultrasonic method using the electromagnetic–acoustic method of exciting–receiving acoustic signals is described. An engineering solution that makes it possible to obtain trains of bottom signals using electromagnetic–acoustic transducers is proposed. The results from determining residual stresses in new and used wagon wheels are presented.
