摘要

为了明确飞机壁板中存在的结构应力对于冲击损伤的影响,基于ANSYS/LS-DYNA隐式-显式连续求解方法,建立了预加载荷飞机壁板受射弹冲击的动力有限元模型,对存在结构应力的壁板受冲击的损伤响应进行了计算分析,分别比较了壁板在受周向拉伸载荷、压缩载荷和无载荷三种应力条件下以及在不同水平应力条件下受到射弹高速冲击和极限速度冲击的响应情况,结果表明:压缩应力对促进结构的屈曲变形、拉伸应力对增大冲击损伤的孔径和程度影响明显。

Abstract

In order to research the influences of the structure stress conditions to the impact damage of aircraft panel, based on the implicit to explicit sequential solution method of ANSYS/LS-DYNA program, the dynamic finite element simulation model of the aircraft panel with stress impacted by the projectile is created and calculated. The simulation results are got respectively with the different levels' tension, compression and without stress in the panel which is impacted by projectiles in high speed and the least speed. The impact response and damage of the panels are compared and the influences of the stress condition of the aircraft panel to the impact response are summed up. The results show that the compression stress can extend the panel's deformation and the tension stress can increase the impact damage hole size and area.
