Experimental Research for Penetration of Simulated Projectile into Concrete Targets
-
摘要: 采用电探针测试技术和分幅照相技术测定了按比例缩小的三种弹丸的着靶速度及侵彻过程，获得了弹丸着靶速度及对应的最大侵彻深度数据。通过对实验数据的分析，给出了估算弹丸着靶速度与最大侵彻深度的经验公式，计算结果与本实验和文献［2, 3, 4］的实验数据相符。Abstract: For three projectiles which size are reduced in proportion, the impact velocities and penetration process were measured and photographed by using the technique of electric probe and framing camera. The maxima of penetration depth corresponding to each impact velocity have been obtained, and through analyzing these data, an experiential formula for predicting the maximal penetration depth is developed, results show the data calculated from the formula are in good agreement not only with that of our experiments, but also with that in the reference.
