摘要
随着航空航天技术的飞速发展,机载外挂真空容器的情况时有发生。吊环常用于固定机载外挂装置,往往需要承受极高的加速度载荷,因此对吊环的结构设计与应力、形变分析显得尤为重要。本文进行了机载外挂真空容器的吊环结构设计,利用ANSYS Workbench对吊环结构进行静力学分析,并在此基础上对吊环结构进行拓扑优化,分析了圆环厚度与吊耳厚度对吊环应力及形变的影响,得到最佳设计参数,实现了吊环的轻量化设计,为机载吊环的设计提供一定参考。
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.
