摘　　要：以伊尔76飞机尾翼前缘结构为对象,对铝合金、GLARE层板、金属面板蜂窝夹芯结构以及复合材料面板蜂窝夹芯结构等四种不同蒙皮材料的抗鸟撞性能进行了对比研究;运用大型非线性动力学软件PAM-crash建立结构有限元模型,通过数值仿真进行计算,并通过试验对分析方法的正确性进行了验证,从结构破坏和吸能特性两个方面进行分析,发现相同条件下,GLARE层板蒙皮重量最小,抗鸟撞能力最强,吸能效率最高,性能最优。Taking IL-76 aircraft wing leading edge structure as the object,the comparison research of the bird impact resistant properties of the aluminum alloy,GLEAR layer board,metal honeycomb sandwich panel structure and composite honeycomb sandwich panel structurewas undertaken. Using large nonlinear dynamics software PAM-crash,the structure finite element model was established. The correctness of the analysis method was verified through the numerical simulation calculation and the experiment. From the analysis of structural failure and energy absorption characteristics,it is found that under the same conditions,the GLEAR laminate skin has the lightest weight,strongest bird impact resistance,highest energy absorption efficiency and best properties.
