理想的飞机结构是用相同的材料和制造方法制造出来的一个整体,复材机身蒙皮/长桁壁板就是这样的结构。然而,目前铝合金飞机机身大都还是组合式结构。出于制造和维护要求,一个结构通常要分解成几部分,然后通过铆钉、螺栓、耳片和接头等连接在一起。对于有集中载荷的地方通常设计接头来传递载荷。接头和接头之间一般采用紧固件-螺栓连接,也可以使用轴承来连接受力构件。按紧固件受力形式可将接头分为两种,紧固件受剪的是耳片,紧固件受拉的角盒。本文将主要介绍耳片接头的结构设计。
The ideal aircraft structure is made of the same materials and manufacturing methods as a whole, complex body fuselage / stern board is such a structure. However, the current aluminum alloy fuselage mostly modular structure. For manufacturing and maintenance requirements, a structure is usually broken down into pieces and then joined together by rivets, bolts, tabs and fittings. For concentrated loads, joints are usually designed to transmit loads. Fasteners commonly used between the connector and the connector - bolted, you can also use the bearing to connect the force member. According to the form of force by the fastener can be divided into two kinds of joints, fasteners are sheared ears, fasteners pull the corner box. This article will introduce the structure of the ear connector design.
