Abstract: With the rapid development of aerospace technology, the situation of vacuum container attached to the outer board of the aircraft often happens. Lifting rings are often used to fix airborne external mounting devices, and often need to bear extremely high acceleration load, so the structural design and stress and deformation analysis of lifting rings are particularly important. In this paper, structural design of the lifting ring applied to airborne external vacuum chamber is carried out, and statics analysis using ANSYS Workbench and topology optimization is carried out on this basis. The results of simulation show the impact of circular ring thickness and lifting ear thickness on the stress and deformation of the lifting ring. The best design parameters are obtained, and the lightweight design of the lifting ring is realized, which may provide a certain reference for the design of airborne lifting ring.

Key words: vacuum chamber, lifting ring, topology optimization, lightweight
