关键字：Ultrasonic peening forming Perforated plate Strengthening ring Curvature radius difference

摘要：Targeting the issue that structure performance cannot be enhanced due to non-peened area being overlarge during shot peening forming of perforated plate, we proposed a peening forming technique of combining strengthening ring with strip peening path. The basic idea of the study is to conduct a ring strengthening around hole and carry out narrow strip peening on shot peening coverage. Then, we investigated the influence of the thickness and width of strengthening ring on the curvature radius difference. Moreover, the thickness and width curves of strengthening ring corresponding to shot peening under different peening parameters such as current intensity and firing pin diameter are discussed critically. The implementation shows that the specific dimension of strengthening ring and strip peening parameters can dramatically reduce the curvature radius difference between peened area around strengthening ring and non-peened area of the hole. With it, we can obtain a good peening forming effect on perforated plate and accordingly optimize the structure of the perforated plate.
