Abstract
The trap panel structure can give full play to the role of dispersing load and reducing regional stress level. The force transfer characteristics of different types of trap panel structures are analyzed, and the main design points of trap panel structures are summarized. Taking the design of a certain type of aircraft with diagonal brace plate as an example, an improved scheme of diagonal brace plate structure (rigid connection of side brace plate and rear beam frame, full connection of lower side and joint strip plate) is proposed, and compared with the other two design schemes. The results show that the shear stresses of the upper wing and upper cabin of the improved brace plate structure are reduced by 19％ and 23％, respectively, and the concentrated load of the rear beam frame is reduced by 67％. The structure has higher efficiency and better stability.关键词
