摘要
为了探究铝合金抑爆油箱的抗弹性能,运用有限元分析软件ANSYS/LS-DYNA对直径12.7 mm的穿燃弹冲击油箱的过程进行数值模拟,分析了油箱箱体的变形情况、弹丸的速度变化和出入口弹孔的孔径,并通过枪击验证数值模拟结果。结果表明,铝合金抑爆油箱相比于没有添加抑爆材料的油箱,具有更好的抗弹性能,着靶面最大变形量减少约26%,出孔面最大变形量减少约19%,弹丸出孔处孔径缩小约20%,非弹道面最大变形量减小约27%。数值模拟与实验结果误差小于8%。网状铝合金中弹后除弹道方向外其他结构较完整,仍具有防护作用。
In order to explore the ballistic behavior of aluminum alloy explosion suppression tank,the finite element analysis software ANSYS/LS-DYNA was used to conduct numerical simulation of the process of penetrating flameproof fuel tank with a diameter of 12.7 mm.The deformation of the tank body,the velocity change of the projectile and the aperture of the inlet and outlet were analyzed,which was verified by shooting experiment.The results show that the aluminum alloy explosion suppression tank has better ballistic behavior than the tank without explosion suppression material.The target surface maximum deformation decreased by 26%,exports face maximum deformation decreased by 19%,the outlet diameter of the projectile reduced about 20%,other surfaces maximum deformation decrease by 27%.The error between numerical simulation and experimental results is less than 8%.The mesh aluminum alloy has a complete structure except the ballistic direction after being shot,and still has a certain protective effect.
