中文摘要：
水流与浮体相互作用时,运动情况十分复杂,目前很难准确有效地模拟。而SPH作为一种纯拉格朗日方法,无需构建网格,用核函数近似粒子进行离散,能较好地解决一些自由面大变形问题。文章利用SPH法对溃坝时引起的高速水流冲击浮体以及水体晃动时破损浮体的运动过程进行模拟。模拟结果表明,SPH法能有效地进行水流对浮体作用的研究。
英文摘要：
Flow-induced floating body motions,that movement is very complicatied,can not be simulated exactly at present.SPH as a Lagrangian method without component grid,uses kernel fuction approximate to particle discretely.And it can solve some problems with strong deformation of free surface.In this paper,SPH method is applied to simulate the process of the floating body motion which results from the collapse of a water column and the movement of damaged floating body in sloshing water.Simulation results show that the SPH method can effectively study the flow indued motion of floating body.
