摘　　要：液舱晃荡是复杂的流固耦合现象。液舱晃荡不仅会影响船舶的稳性,而且会冲击液舱壁面产生巨大的砰击力,对船体结构产生局部破坏,导致液货泄露甚至船体倾覆。论文基于改进的移动粒子半隐式方法建立液舱晃荡的数值模型,通过计算结果和试验的比较,验证数值模型的有效性。在此基础之上,探究不同高度和长度的水平挡板在改善液舱晃荡现象方面的作用。Liquid tank sloshing is a very complex fluid-structure coupling phenomenon.Liquid tank sloshing can not only affect the stability of the ship,but also can generate a huge impact force on the wall of the tank.This force may lead to the leak out of the liquid cargo,and local structure destruction or even the ship capsizing may be resulted in.A numerical model is built based on the improved MPS method,and is verified by the rolling motion of the liquid tank.Influence of the length and height of the horizontal baffle is investigated,which will provide some reference for the shipbuilding and naval architecture.
