摘要:
近壁面气泡载荷是水中战斗部对障碍物毁伤作用的重要载荷之一。以近壁面深水爆炸气泡脉动及射流载荷特征问题为中心，开展了模拟300 m水深环境下的爆炸实验。通过高速摄影仪得到了气泡射流的演化过程；利用Autodyn轴对称模型对气泡射流的演化过程进行了计算，分析了比例距离对气泡脉动周期、射流演化形成时刻及射流强度特征的影响；探讨了壁面近场范围内的压力特征，总结得到射流载荷的演化规律。可为深水环境下水中战斗部对障碍物的毁伤效应研究提供理论参考。
Abstract:
The bubble load near the wall is one of the important loads for underwater warheads to damage obstacles.Focusing on the characteristics of bubble pulsation and jet load in deep-water explosions near the rigid wall, explosion experiments were conducted to simulate a water depth environment of 300 meters. Using the high speed camera, the evolution of bubble jet was obtained. The evolution process of bubble jet was calculated using the Autodyn axisymmetric model, and the influence of scaled distance on bubble pulsation period, jet evolution formation time, and jet intensity characteristics was analyzed. The pressure characteristics within the near-field range of the wall were explored, and the evolution law of jet load was summarized. It can provide theoretical reference for study on the damage effect of warheads on obstacles in deep water environments.
