摘　　要：文章基于势流理论采用边界积分法求解拉普拉斯方程,阐述水面舰船附近三维爆炸气泡脉动过程的计算模型。通过数值计算获得气泡运动规律的同时,着重研究爆炸气泡对船体的载荷。计算结果揭示出爆炸气泡对水面舰船的整体破坏作用。The three-dimensional model of an underwater explosion bubble near a surface ship is described. The boundary integral method is used to solve Laplace equation based on potential-flow theory. Studies are carried out to simulate the bubble motion,with emphasis on the loading of the ship hull. The results demonstrate the destructive effect of the ship hull subject to the explosion bubble.
