中文摘要：

基于流固耦合的方法,利用ANSYS/LS-DYNA软件构建了复合材料层合板鸟撞损伤模型,通过分析层合板鸟撞后的动响应验证了鸟撞过程的4个阶段,探讨了鸟撞过程中冲击波在层合板中的传递情况;分析了层合板在鸟撞时先后出现的基体压缩、基体开裂以及纤维断裂这一损伤过程;研究了铺层方式对鸟撞后鸟体的剩余能的影响.结果表明：合理的设计铺层方式可以有效提升层合板抗撞能力.

英文摘要：

With the fluid-solid coupling method,damage model of the composite laminates under bird impact is built by using the software LS-DYNA; through analyzing the dynamic response of the laminates,four stages of the bird impact process are verified,and spreading of the impact wave in the laminates is discussed. The progressive damage process of matrix compression,matrix cracking,and fiber fracture during the bird impact is analyzed. The effect of different layer styles on residual energy of the bird after impact is studied,and the result proves that properly designed layer style can improve the anti-impact capacity of the laminates effectively.
