Abstract

The present application relates to the technical field of material performance research, and in particular to a closed high-energy elastic wave reduction and residual stress homogenization device. The device includes a pressure vessel containing a fluid medium; and a plurality of ultrasonic transducers distributed and fixedly connected to the side wall and bottom of the pressure vessel, and the transmitting end of the ultrasonic transducer communicates with the inside of the pressure vessel. ; and a support body fastened to the bottom of the pressure vessel, the interior of the support body has an accommodating space for the ultrasonic transducer connected to the bottom of the pressure vessel. The closed high-energy elastic wave reduction and homogenization component residual stress device provided by the present application solves the problem that it is difficult to reduce and homogenize the residual stress of complex structural components in the prior art.

Description

technical field [0001] The present application relates to the technical field of material performance research, and in particular to a closed high-energy elastic wave reduction and residual stress homogenization device. Background technique [0002] As the aerospace industry, pressure vessels, manufacturing and other fields play an increasingly significant role in economic development, and the application of various components in engineering applications is also increasing, the production and quality requirements for various components are also increasing. higher. Due to the existence of component stress, it will directly lead to cracks in the component and induce cracking and other phenomena. Therefore, whether it is the stress generated in the manufacturing process or in the work of the component, the regulation and reduction of the component stress is a key research topic. [0003] In the existing technology, the natural aging method and artificial aging methods such as ...
