摘要
通过有限元软件分析几种改进的飞翼布局桁架型翼梁的受力特性,并与飞翼布局腹板型翼梁受力特性进行对比,证明飞翼布局桁架型翼梁可提高腹板型翼梁的承载能力,对腹板型翼梁的受力特性进行优化;对几种改进的飞翼布局桁架型翼梁的受力特性进行对比,得到最优的桁架型翼梁结构形式。
The stress characteristics of several improved truss-type spar in flying wing layout are analyzed by the finite element software and compared with the stress characteristics of web-type spar in flying wing layout.It is proved that the truss-type spar in flying wing layout can improve the web-type spar in flying wing layout.And the stress characteristics of the web-shaped spar in flying wing layout are optimized.The optimal characteristics of the trusstype spar are obtained by comparing the stress characteristics of the truss-type spar in several improved flying wing structures.
