Damage of hydrodynamic ram effect to riveted fuel tanks

摘要: 为了研究高速侵彻体撞击飞机油箱等充液容器所产生的水锤效应对容器结构产生的灾难性破坏，以铆接油箱为对象，通过开展弹道射击实验，结合数字图像相关测试技术，获取了铆接油箱在射弹冲击作用下的箱体变形、破孔直径等数据；并建立流-固耦合有限元模型，分析射弹入射速度与射弹动能损失、箱体变形、流体动压、铆钉失效之间的关系。结果表明：有限元模拟结果与实验结果基本吻合，数值模型可用于描述油箱在水锤作用下的动力学行为；射弹动能损失、箱体变形量、液体压力峰值与射弹入射速度呈正比例关系；当射弹入射速度达到1400 m/s之后，油箱后壁板开始出现裂纹，并呈花瓣式破孔损伤；当射弹入射速度达到1600 m/s时，铆钉开始发生断裂。Abstract: In order to gain insight into the mechanism of catastrophic damage due to the hydrodynamic ram effect caused by projectiles with high-velocity striking fluid-filled containers such as aircraft fuel tanks, an ballistic shock experiment was carried out by using projectiles to penetrate riveted fuel tanks. The dynamic responses of the rear wall were observed with a three-dimensional digital image correlation technique, and the experimental data were obtained, such as the deformations of the tanks and the diameters of the hole under projectile impact. Also, the fluid-solid coupling finite element model was established based on the experiment to simulate the impact process and the hydrodynamic ram effect under the projectile velocity from 780 to 1600 m/s by analyzing the variation of projectile velocities influencing the kinetic energy reductions, projectile accelerations, the distribution of liquid pressure in the box and the deformation and tearing of the tank wall and rivets. The results show that the finite element simulation results are consistent with the experimental ones. The kinetic energy loss of the projectile, the deformation of the tank, and the peak pressure of the fuel are proportional to the projectile velocity. When the projectile velocity reached 1400 m/s, cracks began to appear on the rear wall of the fuel tank, showing a petal-type hole damage. When the projectile velocity reached 1600 m/s, the rivet began to break.
