Abstract

The weight reduction of UAVs can reduce power consumption, improve the carrying capacity and range, and is of great significance to the green development of the civil aviation industry. Based on the topology optimization theory, the finite element analysis and lightweight design of the UAV fuselage are carried out. Through the optimization and comparison of five schemes, i.e., symmetry, bidirectional draft, unidirectional draft, bidirectional draft+symmetry and squeeze, the comparison results show that the symmetrical optimization is the best scheme. After the optimization of the UAV fuselage model, the mass reduction ratio is 50.24%, the maximum Mises equivalent stress of the model under the load condition is 10.82 Mp, the maximum displacement is 0.7512 mm, and the minimum safety factor is 4.2, which meets the strength and lightweight design requirements of the parts, and provides a new idea and feasible scheme for the lightweight design of the UAV.
