用橡皮泥模拟高速碰撞的实验研究

SIMULATING EXPERIMENTAL RESEARCH OF HIGH SPEED IMPACT WITH PLASTICINE

本文讨论了用长杆橡皮泥弹撞击橡皮泥靶来模拟长杆金属弹高速撞击金属靶的动态响应问题。试验测量了半无限厚度橡皮泥靶的孔径和最终侵彻深度;测定了有限厚度橡皮泥板的弹道极限速度;并用金属弹、靶间撞击效应的理论计算和实验结果进行了检验。研究表明,橡皮泥弹、靶间的模拟撞击实验结果与金属弹、靶间撞击的实验结果和理论计算,都吻合得较好。

This paper discusses the problem of dynamic response, using plasticine as both the projectile and target materials to simulate the high speed impact process of long rod projectiles impinging on targets. The diameter and depth of penetration of plasticine targets with infinite and their ballistic limit with finite thickness, when impinged upon normally by long rods of plasticine, are measured and found to be in agreement with experimental and theoretical calculations based on metal projectiles and targets.
