摘　　要：以35 mm穿甲弹为研究对象,采用JC本构模型,利用ANSYS LS-DYNA动力学分析平台,对不同旋转速度下弹丸侵彻运动装甲钢板进行了模拟研究,从弹丸侵蚀和弹靶作用两方面分析了侵彻效应的相关规律。研究结果表明旋转速度对弹丸侵彻性能具有一定影响:靶板在超音速及亚音速运动条件下,弹丸旋转速度的提高对侵彻性能的影响呈现先提高后降低的趋势;而对于低速运动状态下的靶板,弹丸侵彻性能对弹丸的旋转速度敏感度较低,无相关影响趋势。该研究结果对于不同弹靶交汇条件下提高弹丸侵彻毁伤目标能力具有一定参考意义。Taking 35 mm armor-piercing projectile as the research object,this paper uses JC constitutive model and ANSYS LS-DYNA dynamic analysis platform to simulate projectile penetration of moving armor plate under different rotation speeds.The results show that the rotation velocity has a certain influence on the penetration performance of the projectile.Under the conditions of supersonic and subsonic movement of the target plate,the influence of the projectile rotation velocity on the penetration performance increases first and then decreases.However,for the target plate moving at low speed,the penetration performance of the projectile is less sensitive to the rotation velocity of the projectile,and there is no correlation trend.This paper analyzes the relevant laws of penetration effect from two aspects(projectile erosion and projectile target interaction).The results of this study have a certain guiding significance for improving the ability of projectile penetrating and damaging the target under different projectile target intersection conditions.
