摘　　要：在航空航天领域,飞行器在服役过程中难免遭受飞鸟的撞击,直接威胁着飞行安全,严重时甚至造成机毁人亡的灾难性事故。飞行器结构抗鸟撞设计时,冲击动力学问题的复杂性导致必须把设计、分析、数值仿真和试验验证有机结合起来。受结构材料动态性能及本构参数匮乏、试验方法及仪器装备能力不足等问题的制约,结构抗鸟撞设计周期长、效率低。近年来,西北工业大学冲击动力学研究团队围绕飞机结构抗鸟撞设计,基于积木式设计方法,在结构材料和鸟体动态性能及本构参数确定、连接结构动态失效行为、新概念抗鸟撞结构设计等方面开展了系列创新研究工作,并在国家重点型号飞机结构的抗鸟撞设计中得到了应用。In the field of aerospace engineering,aircraft inevitably encounter bird strikes during their service life,pos⁃ing a direct threat to flight safety and potentially leading to catastrophic accidents involving the loss of aircraft and hu⁃man lives.Due to the complexity of impact dynamics,bird strike resistance design for aircraft structures necessitates an integrated approach combining design analysis,numerical simulation,and experimental validation.However,the lack of dynamic performance and constitutive parameters for structural materials,as well as limitations in experimental methods and instrumentation,resulted in lengthy and inefficient impact resistance design.In recent years,the Impact dynamics research team at Northwestern Polytechnical University has conducted a series of innovative studies focus⁃ing on bird strike resistance design for aircraft structures,based on building block approach.This work addresses the determination of dynamic properties and constitutive parameters of structural materials and bird,the dynamic failure behavior of riveted joints,and the development of a novel anti-bird strike design concept and its application in the bird strike resistance design of a civil aircraft.
