| 摘 要： | 计算物体的撞水响应目前已有了一些专用的算法。在分析和比较这些算法的基础上，提出了一个解撞水问题的边界元耦合界面步进法，该方法不仅可充分发挥边界元计算半空间流场的优越性，更主要是在加速收敛方面有其独到之处。给出圆柱刚体和楔形刚体两个撞水算例，结果表明了该方法的可靠性和有效性。

| Abstract: | A progressive displacement BEM is proposed for treating the impact of rigid body with an inviscid and incompressible fluid. This method not only gives full play of BEM advantages to semi infinite fluid space problems, but also has a good convergence. Two examples of an impacting cylinder and an impacting wedge into initially calm water are presented. The results show that the proposed method is effective. |
