Ultrasonic cavitation impact reduction and homogenization method for residual stress of complex curved surface component

The invention provides a complex curved surface component residual stress ultrasonic cavitation impact reduction and homogenization method, which is characterized in that a container filled with a liquid medium is arranged, an ultrasonic transduction device is mounted on the side wall of the container, and an amplitude-change pole immersed in the liquid medium is fixed at one end, facing the interior of the container, of the ultrasonic transduction device; the method comprises the steps that the complex curved surface component is clamped through a manipulator, a to-be-regulated part of the complex curved surface component is immersed in a liquid medium in a container, and the distance between the to-be-regulated part and an amplitude-change pole is kept within a set distance range by controlling the manipulator; according to the residual stress value of the part to be regulated and controlled, high-strength ultrasonic waves are generated through the ultrasonic transduction device and sent to the part to be r
