摘要

胶层厚度对加筋壁板胶接强度至关重要。以四筋T型长桁加筋壁板为对象，采用三坐标机测量了T型长桁的回弹变形，对壁板进行胶接面剖切观察并测量了胶层厚度，研究了T型长桁回弹变形、缘条宽度和缘条边缘倒角对加筋壁板胶层厚度的影响。同时，采用有限元软件ABAQUS 对T型长桁回弹变形和缘条受压变形进行了仿真计算。结果表明，本试验中的T 型长桁的回弹变形约0.4°~0.5°，回弹变形对胶层厚度具有明显影响。当缘条宽度22 mm时，长桁边缘到长桁腹板胶层厚度呈现由厚再到薄的变化趋势；当缘条宽度73 mm时，长桁边缘到长桁腹板胶层厚度呈现由薄到厚再到薄的变化趋势。长桁边缘倒角可以有效地改善长桁边缘附近的胶层厚度，避免该位置由于蒙皮褶皱导致的胶层厚度突变，进而提高胶接质量。在实际零件研制过程中，可以从以上几个方面进行控制，改善胶层厚度，保证零件胶接强度。

Abstract

The adhesive thickness is very important to the bonding strength of the stiffened panel. Taking fourbar T-shaped stringer stiffened panel as the object

measure the springback of T-shaped stringer by tri-ordinate measuring machine

observe the bonding section and measure the adhesive thickness of the panel by sectioning

to explore several influencing factors

including springback deformation

flange width and edge chamfer of the T-shaped stringer on adhesive thickness. Meantime

simulate the springback and the flange deformation of T-shape stringer by finite element software ABAQUS. The result shows that the springback is 0.4°–0.5°

which has a significant effect on the adhesive thickness. The thickness of adhesive layer from the stringer edge to web changes from thick to thin when flange width is 22 mm. The thickness of adhesive layer from the stringer edge to web changes from thin to thick and then to thin when flange width is 73 mm. The adhesive thickness can be improved by edge chamfer

avoiding sudden change of adhesive thickness because of skin wrinkle

and then improve bonding quality. During part manufacturing

the adhesive thickness can be significantly improved by controlling the above factors to ensure the bonding strength of the parts.
