为研究轻装甲车辆对高速弹丸的侵彻性能,建立尖头弹多角度高速撞击金属靶板的侵彻有限元模型,对弹靶侵彻过程和靶板破坏形式进行分析计算,搭建高速运动分析实验系统,对弹靶侵彻模型进行验证。研究表明:模型结果与实验数据二者吻合较好;有限元模型和实验输出的剩余速度误差不大于5%,模拟的破坏形貌与实验结果较吻合;在一定入射角范围内,弹丸入射角度越大,厚度越大,靶板吸收能量越多。 In order to study the penetration performance of light armored vehicles on high-speed projectile, a penetrating finite element model of sharp-edged multi-angle high-speed impact metal target was established. The penetrating process of the projectile and the damage form of the target were analyzed and calculated, and the high-speed motion analysis Experimental system, the projectile penetration model validation. The results show that the model results are in good agreement with the experimental data. The error of the residual velocity of the finite element model and experiment output is not more than 5%. The simulated failure morphology is in good agreement with the experimental results. Within a certain angle of incidence, The larger the thickness, the more energy absorbed by the target.
