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.
Abstract:
With the fluid-solid coupling method,damage model of the composite laminates under bird impact isbuilt by using the software IS-DYNA; through analyzing the dynamic response of the laminates，four stages ofthe bird impact process are verified，and spreading of the impact wave in the laminates is discussed. The pro-gressive damage process of matrix compression，matrix cracking， and fiber fracture during the bird impact is an-alyzed. The effect of different layer styles on residual energy of the bind after impact is studied,and the resultproves that properly designed layer style can improve the anti-impact capacity of the laminates effectively.
