AI Technical Summary
Existing technologies in the prestressed shot peening process of large curvature wall panel frame structures have the following risks: high coverage of the thickened area, discontinuous shape of the web area, difficulty in eliminating spherical deformation, and edge damage. Moreover, existing protection methods cannot simultaneously guarantee high precision and high reliability.
A prestressed shot peening forming fixture was designed, including a fixture protective layer, a wall panel protective layer, a pre-bending gap filling layer, and a frame filling layer. By partitioning shot peening forming and optimizing shot peening parameters, combined with a three-point clamping method, the protection and forming of the wall panel can be achieved.
It achieves high-precision and reliable protection, avoids problems such as high coverage of the thickened area and discontinuity in the shape of the web area, eliminates spherical deformation, does not affect the application of prestress, and is easy to operate and reusable.
