摘　　要：飞机是高价值军事目标,毁伤研究难以直接针对真机开展,设计等效靶代替真实目标开展毁伤试验和仿真研究是目标易损性和毁伤评估研究的重要手段。提出了依据不同等效对象毁伤特性和使用需求的分层次等效靶设计方法,重点关注破片毁伤元作用下飞机部件/分系统的“物理与功能”毁伤等效技术,在此基础上综合考虑目标内外环境等效以及加工、运输等多方面的因素,建立了飞机目标毁伤等效靶的详细设计流程。然后根据提出的方法,针对预警机雷达天线罩进行了等效靶设计,并加工试验件,开展了地面静爆毁伤试验测试,结合试验结果验证仿真方法的准确性后,通过冲击有限元仿真确定了典型破片打击雷达天线罩不同区域的弹道极限速度和相应的临界穿透能量阈值,验证了所提等效靶设计方法的合理性和可用性。提出的等效靶设计方法可为防空武器弹药毁伤能力检验评估、飞机目标毁伤标准制定以及联合作战演训活动提供支撑。As a high-value military target,it is difficult to directly conduct damage research on real aircraft.Designing equivalent targets to replace real targets in damage tests and simulation research are important means for target vulnerability and damage.A target design method is proposed based on the damage characteristics and usage requirements of equivalent objects,with a focus on the"physical and functional"damage equivalent tecnology of aircraft components/subsystems under the threat of fragments.On this basis,a detailed design process for equivalent targets of aircraft is established by comprehensively considering the equivalence of the target's internal and external environment,as well as various factors such as processing and transportation.Then,based on the proposed method,an equivalent design target is carried out for the radar antenna cover of the early-warning-aircraft(EWA),and ground static explosion damage tests are carried out on the equivalent components.After verifying the accuracy of the simulation method with the test results,the ballistic limit velocity and corresponding critical penetration energy thresholds of diffrerent areas for the typical fragment hitting radar antenna cover are determined through impact finite element simulation,the rationality and usability of the proposed equivalent target design method is verifyed.The equivalent target design method proposed can provide support for the inspection and evaluation of the damage ability of air defense weapons and ammunition,the formulation of aircraft target damage standards,and joint combat training activitis.
