Abstract

See full text

A device and method for reducing and homogenizing residual stress of a component by an array of high-energy elastic waves. The device includes a tubular body consisting of at least two elements, multiple first through holes and a clamping device provided on an outer side of the tubular body. Exciters are connected with exciting wedges so that an end face of each of the exciting wedges is closely coupled to a surface of the component. A connection portion is coupled to an emitting end of each of the exciters, where the axis of the emitting end coincides with a normal line at a pressed surface of the component A multi-channel signal amplifier is electrically connected to each of the exciters and a multi-channel excitation control module is electrically connected to the multi-channel signal amplifier.
