受轴向拉伸载荷作用的耳片强度研究

耳片是飞机结构的重要连接元件,是结构主要传力通道上的重要环节,是飞机结构强度计算和细节分析的重点部位。多年来,许多国内外学者、专家对其进行了大量试验研究工作。大量的试验表明,随着加载角度的增大,耳片的静拉伸破坏载荷降低,所以,现在在设计中,都尽量采用受轴向载荷的耳片。本文对受轴向拉伸载荷作用下的单、双耳片进行了强度分析研究,并进行了归纳总结。

Study of Lug Strength under Axial Tension Loads

Lug,as an attachment element in airframe structure, is an important link of the main route of force transfer in structure, and also is a critical part in structure strength calculation and detail analysis. In many years, there are a lot of national and foreign experts and scholars who did a great deal of experiments and researches,many of which have shown that along with the increasing of load angle, the lug crash load of static tension is reducd. Therefore,lugs under axial load shall be used as full as passible in design. In this article,a strength analysis of single double lugs under axial tension loads is conducted.
