摘要
利用MSC．Dytram软件中的具有强度的多材料欧拉网格模拟了高速运动气泡对靶板(岩石)的冲击过程,研究了靶板破坏深度、破坏宽度与气泡初始压力、速度以及入射方向等的关系,试图指出这些关系的物理意义并分析射流破岩机理．
The dynamics of a single high-speed bubble impacting with a solid target are simulated by MSC.Dytran The relations between the damage depth or damage width and the initial pressure, velocity, the incident angle of bubbles and drips, and the thickness of target, are presented in curves, and the physical mechanism is discussed. The theory of water jet impacting rock is also discussed.
