概述民用飞机典型框结构大多采用对拉接头进行连接,为了验证对拉接头的损伤容限特性,需进行损伤容限试验,试验前需先对试验方案进行论证和确定。本文通过对典型框对拉接头进行有限元分析,找出了对拉接头的应力严重部位,确定了某型飞机典型框对拉接头结构的损伤容限试验方案。
Overview Typical structure of civil aircraft typical box structure used to connect the pull joint, in order to verify the damage tolerance characteristics of the pull joint, the damage tolerance test required before the test demonstration and determination of the test program. In this paper, finite element analysis of the pull tab of the typical box was carried out to find out the stress location of the pull tab and to determine the damage tolerance of the typical box to the pull tab structure of a certain type of aircraft.
