本文对矩形水箱内液体在平动激励下的晃动进行了数值分析。本研究使用的数值工具是基于改进的移动质点半隐式(MPS)方法开发的内部求解器MLParticle-SJTU。将数值模拟结果与无隔板三维水池实验结果进行了对比，验证了数值模拟方法的有效性。研究了侧壁的冲击压力和自由面的变形。为了减小晃动幅度，在水舱中部设置了垂直挡板。此外，改变了垂直挡板的布置方式，研究了垂直挡板对冲击压力和流场的影响。数值计算结果的对比表明，垂直挡板的布置对冲击压力和流场有重要影响。
This paper presents a numerical analysis of liquid sloshing in a rectangular tank under translational excitation. The numerical tool used in this study is an in-house solver MLParticle-SJTU which is developed based on improved moving particle semi-implicit (MPS) method. The validity of solver is proved by comparing the results of numerical simulation and experiment in three-dimensional (3-D) tank without baffles. The impact pressure on lateral wall and the deformation of free surface are investigated. In order to reduce sloshing amplitude, vertical baffles are installed in the middle of tank. Furthermore, the arrangement of vertical baffles is changed to research the effects on impact pressure and fluid field. The comparison of numerical results shows that the arrangement of vertical baffles plays an important role in impact pressure and fluid field.
