Experimental study of residual stresses and interference of locomotive wheels by the acoustoelasticity method

Resumo

ltrasound method to evaluate residual stresses in locomotive wheels using the electromagnetic–acoustic excitation and reception of elastic waves is described. The results of residual stress distribution throughout the wheel thickness before and after fitting of wheel centers are presented. A method for controlling the interference of locomotive wheels by the measured values of residual stresses using the acoustoelasticity method is proposed.
