中文摘要：

根据飞机设计原则和相关适航条例,航空轮胎爆裂所产生的高速轮胎碎片是在航空结构设计中必须考虑的一种严重威胁。在冲击速度一定的条件下,大尺寸轮胎碎片往往具有比小尺寸碎片更严重的危害。针对两种航空铝合金材料,首先通过试验得到了两种材料的基本力学性能,然后通过有限元方法计算了两种材料的飞机壁板抵抗大尺寸轮胎碎片冲击的动态响应,并对两种材料的抗冲击性能进行了对比分析。结果表明：AL01型铝合金具有更优的抗冲击性能。

英文摘要：

According to aircraft design principles and related airworthiness regulations, the high-speed fragment caused by tire blowout is a severe threat which must be considered in aircraft structure design. With a certain impact velocity, large size tire fragment usually leads to severer damage than small size fragment. Aiming at two types of aviation aluminium alloys, the basic mechanical properties of the two materials can be obtained by experiments. With finite element method, the dynamic responses of the aircraft panels with two materials under the impact of large size tire fragment were calculated, and the impact resistances of the two materials were compared. The results indicate that AL01 type aluminium alloy exhibits a better performance.
