应用改进的SPH方法模拟棱形液舱在不同充液比、横摇激励频率工况下的液体晃荡行为。该方法能模拟出液体大幅度非线性晃荡产生的翻卷、破碎等现象，模拟结果与实验结果吻合较好。通过改变舱体结构，对带有隔板的棱形液舱进行数值模拟，分析隔板对液体晃荡特性的影响。结果表明：充液比及激励频率对液体的晃荡特性有重要影响，且适当改变箱体结构可以有效地抑制晃荡现象。

In this study, the improved smoothed particle hydrodynamics ( SPH) method was used to simulate the liquid sloshing in a prismatic tank under shaking excitation with different water depths and excitation frequencies. With this method, the roll-up and break-up of liquid caused by violent nonlinear sloshing can be simulated, and the simulation results were consistent with experimental data. Through changing the structure of the prismatic tank, the liquid sloshing in the prismatic tank with a baffle was simulated and the influence of the baffle on the liquid sloshing was analyzed. The results show that the water depth and the excitation frequency are the major factors influencing the characteristics of the liquid sloshing, and appropriately changing the structure of the tank can effectively suppress the liquid sloshing.
