| 摘要: |
| 为明确残余应力对2024-T3搅拌摩擦焊多焊缝整体加筋壁板稳定性的影响，采用ANSYS有限元软件建立了2种典型搅拌摩擦焊接多焊缝加筋壁板数值计算模型。通过热力耦合算法分别计算了2种加筋壁板（A，B）的残余应力分布，并对其进行屈曲和后屈曲分析。结果表明：多焊缝整体加筋壁板的残余应力受焊接顺序影响，加筋壁板A的残余应力主要集中在长桁右侧，加筋壁板B的残余应力则集中在焊接顺序靠后的长桁处。残余应力对加筋壁板稳定性影响较大。考虑残余应力后，加筋壁板A的临界屈曲载荷降低了14.2%，加筋壁板B降低了12.4%。 |

| Abstract: |
| In order to clarify the influence of residual stress on the stability of 2024-T3 friction stir welded(FSWed) integral stiffened panels with multi-welds, the ANSYS software was used to establish the finite element models of two typical multi-FSWed stiffened panels. The residual stresses of two typical multi-welded stiffened panels (Panel A and Panel B) were calculated respectively using the thermal-mechanical coupling method. And the buckling and post-buckling responses of the stiffened plates were analyzed. It is shown that the residual stress distribution of stiffened panel was affected by the welding sequence. The maximum residual stress of Panel A mainly appears on the right side of the stringer, and that of Panel B appears on the stringer that is welded later. The residual stress has a great influence on the stability of the welded stiffened panels. When the residual stress profiles are taken into consideration, the critical buckling loads of welded Panel A and Panel B will decrease 14.2% and 12.4% respectively. |
