民用飞机外翼与中央翼上壁板连接形式的研究

在现代民用飞机的设计研发中,外翼与中央翼连接处的设计和装配是重中之重。通过对5种外翼与中央翼上壁板连接形式进行研究,建立CATIA模型,通过有限元计算,得出相同载荷形式下的应力应变情况。并从受力、工艺和重量等方面进行分析、比较,初步给出几种外翼与中央翼连接形式的优劣。旨在为类似机型外翼与中央翼上壁板连接形式的确定提供有效思路和技术支持。

Research on the Upper Panel Joint of Outer Wing and Center Wing for Civil Aircraft

The design and assembly of joint between outer wing and center wing is essential for the developing commercial aircraft. Five kinds of joints for upper panel between outer wing and center wing were researched in this article. CATIA models were established. Using the finite element calculation, the stress and strain condition of the same load was obtained. Comparation and analysis were given from loading, manufacturing and weight, in order to get the advantages and disadvantages of the different joints. The research could provide a technology support for civil aircraft structure design.
