摘要

为研究带预侵蚀头部弹体的高速侵彻性能

基于时序侵彻机制建立预侵蚀弹体侵彻计算模型

设计制作带预侵蚀头部弹体

并利用30mm弹道炮开展缩比弹体高速侵彻混凝土靶试验

分析了高速侵彻下预侵蚀头部弹体的质量磨蚀特点和侵深变化规律。研究结果表明:建立的侵彻计算模型考虑了异形头部综合头形系数和预破坏机制

能反映带预侵蚀头部弹体的阻力特征;设计的预侵蚀弹体较基础弹型的侵蚀量减小

侵彻能力提高;带预侵蚀头部弹体通过预破坏、阻应力向两级头部分配并降低和预侵蚀变形等机制

降低侵彻阻力

提高弹体高速侵彻性能

结果可为高速侵彻弹体设计提供参考。

Abstract

The high-speed penetration performance of a projectile with pre-eroded nose is studied.A penetration calculation model for the projectile with pre-eroded nose is established based on the sequential penetration mechanism.A projectile with pre-eroded nose is designed and fabricated

and the experiment on the high-speed penetration of a scaled-down projectile into concrete target is conducted using a 30mm ballistic gun.The mass abrasion characteristics and penetration depth variation laws of the projectile under high-speed penetration are analyzed.The results indicate that the proposed penetration calculation model takes into account the comprehensive nose shape coefficient and pre-failure mechanism of the special-shaped nose

and can reflect the resistance characteristics of the projectile.The designed projectile with pre-eroded nose has a reduced erosion amount compared to the basic projectile type

and its penetration capability is improved.The projectile reduces penetration resistance and improves high-speed penetration performance through the mechanisms of pre-destruction

stress distribution to the two-stage nose

and pre-erosion deformation.The results can provide reference for the design of high-speed projectiles.
