动能弹侵彻机理及其防护研究进展

动能弹是一种打击地下深层战略目标的重要武器装备，研究其侵彻机理及防护技术意义重大。综述了近年来动能弹侵彻机理的相关研究进展，指出国内外动能弹侵彻机理的实验研究多集中在v＜1300 m／s的中低速范围内，经验公式多考虑弹体为刚性弹或变形非消蚀弹，相关的理论模型和数值模拟研究已初成体系，而动能弹高速／超高速侵彻技术的研究仍处于起步阶段，其破坏机制尚不清晰；从增大遮弹层强度、优化遮弹层结构和设计偏航层3个方面总结了新型抗侵彻防护技术的研究成果；对未来的研究工作提出了建议。

Research Progress of Kinetic Energy Projectile Penetration Mechanism and Protection

Kinetic energy projectile plays an important role in attacking deep underground targets.It is very important to study its penetration mechanism and protection technology.Firstly,the paper reviewed the recent progress of the kinetic energy projectile penetration mechanism,and pointed that experimental study were more concentrated in the low-speed range(v<1 300 m/s),and the existing empirical formulas more considerate rigid projectile or deformed non-eroded projectile,and relevant theoretical models and numerical simulation studies had formed into early system.But the research of high-speed/ultra high-speed kinetic energy projectile penetration technology is still in its infancy and its failure mechanism is not yet clear.Secondly,the paper summarized the research results of new anti-penetration protection technology from the view of increasing the strength of bursting layer,optimizing layer structure and designing yaw.Fi-nally,some research proposals were given for the future study.
