Embodiment Construction
[0017] The specific embodiment of the present invention is described in detail as follows in conjunction with accompanying drawing:
[0018] Such as figure 1 Shown is the principle diagram of the closed-loop control system of the present invention, which includes: high-energy ultrasonic transducer (1), high-power ultrasonic amplifier (2), ultrasonic signal excitation multi-channel controller (3), residual stress closed-loop controller ( 4), ultrasonic signal processing module (5), energy concentrator (6), coupling agent (7), workpiece (8), residual stress detection transducer (9). When adjusting the residual stress of a certain workpiece, the multi-channel controller (3) is first excited by the ultrasonic signal to cooperate with the software to control multiple high-power ultrasonic amplifiers (2) to generate driving signals, and the driving signals excite multiple high-energy ultrasonic transducers ( 1) Generate a high-energy ultrasonic beam, and focus the energy of the hig...
