摘　　要：基于有限元计算方法,从侵彻深度、弹体残余速度以及弹体偏转效应3个方面研究了花岗岩与C15素混凝土的抗侵彻能力.通过与实验数据和理论结果的对比验证了计算模型的有效性,在此基础上,对弹体在0°~90°的倾角范围内,以4种不同速度斜侵彻花岗岩与C15素混凝土的结果进行了分析.结果表明,在相同条件下,弹体斜侵彻C15素混凝土的深度和残余速度均大于花岗岩;弹体会存在不同的跳弹极限角,相同速度下,斜侵彻C15素混凝土弹体的跳弹极限角大于花岗岩,花岗岩对弹体的偏转效应相较于C15素混凝土更明显.Based on the finite element calculation method,the anti penetration ability of granite and C15 plain concrete was studied from three aspects:penetration depth,residual velocity of the projectile,and deflection effect of the projectile.The effectiveness of the computational model was verified through comparison with experimental data and theoretical results.Based on this,the results of the projectile's oblique penetration of granite and C15 plain concrete at four different speeds within the inclination range of 0°to 90°were analyzed.The results show that under the same conditions,the depth and residual velocity of the projectile's oblique penetration into C15 plain concrete are greater than those of granite;The projectile will have different jump limit angles.At the same speed,the jump limit angle of the oblique penetration of C15 plain concrete projectile is greater than that of granite,and the deflection effect of granite on the projectile is more significant than that of C15 plain concrete.
