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。
In this paper, we discuss the dynamic response of a long rod rubber bomb that collides with a plastic target to simulate the high speed impact of a long rod metal bomb against a metal target. The hole diameter and the final penetration depth of the semi-infinite thickness plasticine target were measured. The ballistic limit velocity of the plasticine plate with the finite thickness was measured. The theoretical calculation and experimental results of the impact between the metal shell and the target were carried out. The results show that the experimental results of the simulated impact between the plasticine bomb and the target are in good agreement with the experimental results and theoretical calculations of the impact between the metal bomb and the target.
