偏转式抗侵彻防护技术研究现状

Research Status of Deflected Anti-penetration Protection Technology

随着弹体侵彻能力不断提升,传统“阻挡”的防护设计思想指导下的防护结构为达到防御目标,其质量与尺寸必将不断提高。基于弹体非理想侵彻及侵彻非均匀防护结构中的弹体偏转现象而提出的“偏转”防护思想,使得更加轻质高效的防护结构成为可能。本文以弹体侵彻过程中的各种偏转现象为主要研究对象,综述了偏转式抗侵彻防护技术的研究现状,主要内容包括弹体非理想侵彻过程和弹体侵彻非均匀防护结构过程中的偏转现象,非理想侵彻的过程分析以及影响弹体非理想侵彻过程中偏转程度的主要因素,非均质防护结构偏转弹体的机制,介绍了目前实际应用中较为典型的三种偏转式防护结构形式,并分析了其抗侵彻性能和存在的不足,最后针对目前偏转式抗侵彻防护技术研究现状提出了建议,为高效能偏转式防护结构研究提供参考依据与思路。

As the penetration capability of the projectile increase,the weight and size of protective structures guided by the traditional"blocking"protective design concept are bound to rise to achieve the defense objectives.The idea of‘deflection’protection based on non-ideal projectile penetration and projectile deflection in non-uniform penetration protection structures makes it possible to have lighter and more efficient protection structures.This paper reviews the current status of research on deflected anti-penetration protection technology by focusing on various deflection phenomena in projectile penetration.The main contents include the deflection phenomena in the process of non-ideal penetration of the projectile and the process of penetration of the projectile into the non-homogeneous protective structure,the analysis of the process of non-idealpenetration,and the main factors affecting the degree of deflection in the process of non-ideal penetration of the projectile,the mechanism of deflection of the projectile in the non-homogeneous protective structure,the introduction of the three typical forms of deflected protection structure in the current practical application,and the analysis of their anti-penetration performance and the existence of deficiencies.Finally,the current research status of deflected anti-penetration protection technology is proposed to provide a reference basis and ideas for developing high-performance deflected protection structures.
