Abstract

Different shot peening sequences can affect the effectiveness of shot peening definitely. To comprehensively investigate the ramifications of different shot peening sequences on the structural integrity of aviation components, this study formulates a shot peening sequence model tailored to the cross-sectional features of H-shaped slide rails commonly found in aircraft, leveraging Abaqus and Python. Combining numerical simulations and experimental data, we utilize the Euclidean distance to assess the similarity of residual stress distribution curves. Effects of six different shot peening surface strengthening sequences on the residual stress distribution and deformation across each surface of the aircraft slide rail’s typical cross-section are analyzed. Results indicate that variability exists in the similarity of maximum residual stress distribution among surfaces subjected to different shot peening sequences. Notably, the fully symmetric strengthening sequence S4 yields the highest similarity in the residual stress distribution curve. Moreover, the maximum deformation of the workpiece groove exhibits a 26.3% disparity under various shot peening strengthening sequences. This indicates that an appropriately selected shot peening sequence can mitigate size errors arising from the strengthening process. This implies that a judiciously chosen shot peening strengthening sequence could enhance the overall shot peening quality of the component.

喷丸强化顺序对复杂航空部件强化性能的影响与分析

不同的喷丸强化顺序对喷丸强化效果有明显的影响。为了全面研究不同喷丸顺序对航空部件结构完整性的影响，本研究利用Abaqus和Python，根据飞机上常见的h型滑轨的横截面特征，制定了一个喷丸顺序模型。结合数值模拟和实验数据，利用欧几里得距离来评价残余应力分布曲线的相似性。分析了六种不同喷丸表面强化顺序对飞机滑轨典型截面各表面残余应力分布和变形的影响。结果表明，不同喷丸强化顺序下表面最大残余应力分布的相似性存在差异。其中，完全对称强化序列S4在残余应力分布曲线上的相似性最高。不同喷丸强化顺序下，工件槽的最大变形量相差26.3%。这表明适当选择喷丸强化顺序可以减轻强化过程中产生的尺寸误差。这说明合理选择喷丸强化顺序可以提高零件的整体喷丸质量。

期刊介绍： The Journal publishes and disseminates original research in the field of material forming. The research should constitute major achievements in the understanding, modeling or simulation of material forming processes. In this respect ‘forming’ implies a deliberate deformation of material. The journal establishes a platform of communication between engineers and scientists, covering all forming processes, including sheet forming, bulk forming, powder forming, forming in near-melt conditions (injection moulding, thixoforming, film blowing etc.), micro-forming, hydro-forming, thermo-forming, incremental forming etc. Other manufacturing technologies like machining and cutting can be included if the focus of the work is on plastic deformations. All materials (metals, ceramics, polymers, composites, glass, wood, fibre reinforced materials, materials in food processing, biomaterials, nano-materials, shape memory alloys etc.) and approaches (micro-macro modelling, thermo-mechanical modelling, numerical simulation including new and advanced numerical strategies, experimental analysis, inverse analysis, model identification, optimization, design and control of forming tools and machines, wear and friction, mechanical behavior and formability of materials etc.) are concerned.
