摘　　要：该文基于自主开发的无网格粒子方法求解器MLParticle-SJTU,研究了二维晃荡问题中对称水平隔板的隔板宽度、高度等参数对减晃作用的影响。首先,对矩形液舱内的晃荡问题进行了数值模拟,通过与实验结果进行比较,验证了MLParticle-SJTU的可靠性;其次,通过大量的数值计算,分析了对称水平隔板的宽度和高度对减晃效果的影响。数值结果表明:对称水平隔板具有较好的减晃作用;对称水平隔板宽度和高度越大,减晃效果越明显。In this paper, the self-developed meshfree particle method solver MLParticle-SJTU, which is based on MPS （Moving Particle Semi-implicit） method, is used to investigate the effects of the baffles on the liquid sloshing under horizontal excitation. Firstly, the numerical model is validated against the experimental data for 2D liquid sloshing in unbaffled tank. In addition, liquid sloshing with different baffle heights and widths is simulated. The impact pressure characteristics in these cases are parametrically investigated. Results show that the dimension and location of horizontal baffles significantly influence the hydrodynamic damping. Liquid sloshing displacement can be suppressed effectively as the baffle height and width increases.
