摘　　要：飞机襟翼支架是与其机翼连接的重要运动部件,为优化飞机襟翼支架结构,运用Altair Inspire软件对襟翼支架进行轻量化设计。在满足飞机机翼使用性能的条件下选用襟翼支架的材料为AL2014-AREO,依据10%、15%、30%体积约束目标下襟翼支架的优化结果,通过Poly NURBS自动拟合和手动拟合对优化模型进行几何重构与强度校核,得到最优轻量化模型。优化后的飞机襟翼支架的质量为46.31 g,比优化前下降了77.59%,极大地减轻了飞机襟翼结构的整体质量,并且优化后飞机襟翼支架的位移量、安全系数、米塞斯等效应力均符合设计要求。该研究为飞机襟翼支架的设计与改进提供了一种新思路。The aircraft flap support is an important moving part connected to its wing.In order to optimize the structure of the aircraft flap support,the Altair Inspire software is used to lightweight design the flap support.This paper selects AL2014-AREO material for the flap support under the condition of meeting the performance of the aircraft wing.Based on the optimization results of the flap support under the volume constraints of 10%,15%and 30%,the optimized model is geometrically reconstructed and strength verified through PolyNURBS automatic fitting and manual fitting,and the optimal lightweight model is obtained.The mass of the optimized aircraft flap support model is 46.31 g,which is 77.59%lower than that before optimization,and greatly reduces the overall weight of the aircraft flap structure.The displacement,safety factor,and Mises equivalent stress of the optimized aircraft flap support all meet the design requirements.The research results provide a new approach for the lightweight design and structural improvement of aircraft flap support.
