摘要

以舰载机前机身结构和前起落架部分构件为研究对象,分析其在地面弹射过程中,弹射力冲击下的动态响应。通过地面弹射模拟试验和刚柔耦合模拟对比分析,发现试验结果与模拟结果基本吻合,从而验证了地面模拟弹射冲击加载试验方法的可靠性及刚柔耦合模拟方法的可行性。由试验结果和模拟分析,可得出弹射过程中飞机前机身结构最大过载传递路径和应变分布,同时给出了前机身动态应力分布。地面弹射试验和模拟为舰载机的结构设计、强度校核以及整机弹射试验提供了参考依据。

Abstract

In this paper, the front fuselage structure of a carrier-based aircraft and some components of the nose landing gears are studied. The dynamic responses of the structure under the impact force during the ejection process are analyzed. A comparison is made between the ground ejection test and rigid-flexible coupling simulation. The test results are found to be consistent with the simulation results, verifying the feasibility and reliability of the ground ejection impact test and the method of rigid-flexible coupling simulation. Based on the test and simulation results, the maximum overload transferring paths are obtained, as well as the strain and stress distribution of the aircraft fuselage structure during the ejection process. The results of the ground ejection test and simulation can provide reference to structure design, strength check and the whole aircraft ejection test for the carrier-based aircraft.
