Abstract:

In order to provide reference and technical guidance for the practical application of adhesive technology in steel-aluminum body, the influence of hygrothermal environment on the performance of adhesive joints under different stress states is studied. The Single Lap Joints (SLJs), 45°Scarf Joints (SJs) and Butt Joints (BJs) are selected as the research objects. After the adhesion and curing of specimens, experiments of 20, 40 and 60 hygrothermal cycles are completed according to hygrothermal cycle spectrum. The results show that with the increase in hygrothermal cycles, the failure loads of three kinds of joint all decrease, and the SJs have the biggest decrease amplitude, namely the failure load decreases significantly under the combine stress of shear and normal. At the same time, the failure modes of the joints have also changed after the hygrothermal cycles. The normal stress and shear stress of the adhesive layers are calculated and the curves are fitted. The stress criterion is selected as appropriate expression of joint failure criterion after different hygrothermal cycles. Based on this, the failure criterion formula and 3D surface with different aging cycles of the joints are established.

Key words: vehicle engineering, steel-aluminum body, adhesive technology, hygrothermal aging, stress state, failure criterion
