动能弹斜侵彻钢筋混凝土性能影响研究

为研究不同倾斜角、攻角对动能弹侵彻钢筋混凝土性能的影响,采用AUTODYN有限元软件对该问题进行分析,获得不同倾斜角、攻角下动能弹贯穿钢筋混凝土靶板的速度降曲线及横向偏移距离。结果表明:随侵彻倾斜角、攻角的增大,动能弹贯穿靶板后速度降越大、剩余动能越小,横向偏移距离越大;弹着点在钢筋网节点上时钢筋混凝土抗侵彻性能更高。

Performance of kinetic projectile penetrating reinforced concrete obliquely

In order to study the influence of different inclination angle and attack angle on performance of kinetic projectile penetrating reinforced concrete obliquely,numerical calculation software AUTODYN was used to obtain the speed drop curve and horizontal offset distance after kinetic projectile penetrating reinforced concrete under different inclination angle and attack angle. The result shows that the greater inclination angle and attack angle lead to the greater speed drop,smaller kinetic energy and greater horizontal offset distance. When the impact point is on the steel mesh node,the reinforced concrete will have higher penetration resistance.
