    摘要:

    喷丸成形技术利用特定能量源产生冲击压力,在壁板表层深度方向引入非均匀分布的塑性应变,是一种柔性冷加工塑性成形技术,适用于大尺寸复杂型面整体壁板的成形制造。对喷丸成形的工艺建模方法、工艺规划方法两个方面进行了综述;梳理了喷丸成形数值模型的发展历程,分析了固有应变模型在喷丸成形模拟中的显著优势;对喷丸成形工艺规划方法进行综述,介绍了传统工艺规划途径,指出其无法适应现代工业发展需求的原因,对基于数值模型的工艺规划进行了回顾,分析研究成果存在的问题与难点并提供解决思路,试图为喷丸成形技术未来发展的研究与工程应用提供参考与借鉴。

    Abstract:

    Peening forming (PF) utilizes a specific energy source to generate impact pressure and introduces non-uniformly distributed plastic strain along with the depth of the panel. It is a flexible and cold-working forming technology, which is suitable for producing large-scale panels with a complex shape. The process modeling method and the process planning method of PF were reviewed in this study. The development of the process model of PF was first introduced, and the significant advantages of the eigen-strain model utilized in PF simulation were discussed. The traditional process planning approaches were presented, and the reasons why they cannot meet the needs of modern industrial requirements were pointed out. The planning methods on the basis of the process model were reviewed, the problems and difficulties in the research results were analyzed, and feasible solutions were presented, trying to provide references for the research and engineering applications of the PF technologies in the future.
