Based on the coupled Eulerian-Lagrangian (CEL) method, a dynamic response simulation model was proposed for the impact of tire burst debris on the aircraft fuel tank cover structure, which fully considered the interaction between the fuel tank cover structure and fuel. At least three tire debris impact tests were conducted on a typical fuel tank cover according to the airworthiness regulation speed, and the effects of internal air pressure and tank sloshing of the fuel tank cover during the impact were investigated. Through the experimental and numerical analysis of fuel tank sloshing, fuel pressure and plastic strain, it was found that the increase of fuel volume and impact position would have a serious impact on the safety during the impact of tire bursting debris on the fuel tank cover, and may course the fuel tank leak. The test method in this paper meets the airworthiness requirements, and the proposed impact simulation method can be used in the structural analysis and optimization design.

基于耦合欧拉-拉格朗日（CEL）方法，提出了轮胎爆裂碎片对飞机油箱盖结构影响的动态响应仿真模型，充分考虑了油箱盖结构与燃油的相互作用。根据适航调节速度对典型油箱盖进行了至少3次轮胎碎屑冲击试验，研究了碰撞过程中油箱盖内部气压和油箱晃动的影响。通过对油箱晃动、燃油压力和塑性应变的实验和数值分析，发现在轮胎爆裂碎片撞击油箱盖的过程中，燃油体积和撞击位置的增加会对安全产生严重影响，并可能导致油箱泄漏。
