Firstly, the paper describes the development history and current situation of UAV, and then analyzes and studies some main structural optimization design methods. On this basis, software is selected to carry out multi-objective optimization design analysis of UAV wing structure. In the process of optimization design, it is necessary to ensure that it meets the requirements of strength and stiffness. Through the detailed analysis of the structure of the UAV, the finite element model of the wing structure is established, and then the node load acting on the UAV wing model is calculated through the corresponding manual and specification of the aircraft design, and the most severe load condition is determined for the subsequent structural analysis and optimization design work: the paper further studies the most severe load condition selected In this case, the multi-objective optimization design of the UAV wing structure is carried out by taking the cross-sectional area of the tension line and the front and rear beam edge as the design variables, and the most satisfactory design scheme and its structure size are obtained. Finally, the final optimization scheme and the original design scheme are compared and discussed under some typical load conditions in the UAV flight envelope.
