摘要
利用ANSYS软件对机翼接头进行强度分析,并对螺栓孔的应力集中问题进行研究。通过在不同工况下对接头的有限元分析,得出了接头的应力分布规律,然后根据分布规律改进了接头模型,有效地降低了螺栓孔的应力集中,为结构优化设计提供了一种辅助设计方法。
Strength analysis of the wing joint is made based on ANSYS,and the stress concentration of bolt holes is studied. The stress distribution law of the wing jaint is obtained by finite element analysis of the wing joint under different conditions. And the wing joint is improved according to the stress distribution law,makes the stress concentration of bolt holes decreased effectively. So the aided design method of structural optimization is proposed.
