| 摘 要： | 针对液舱内隔板的可渗透特性，采用多域边界元方法，对流体晃荡问题进行了非线性时域模拟计算与分析。计算研究表明，多域边界元方法能够准确地模拟带有可渗透隔板的液舱内流体晃荡现象。对应于没有隔板和有完全不可渗透隔板情形的计算结果与相应的实验和理论结果吻合良好，带有不同渗透率的隔板在一定程度上改变了结构的固有振荡频率，隔板的可渗...

| Abstract: | The nonlinear sloshing in liquid tank with porosity girder is successfully simulated in time domain by multiple domain boundary element method. The simulation results agree well with that of referenced cases with impermeable girder or without girder. The natural frequency of the liquid tank with porosity girder changes while the porosity coefficient of the fitted girder varies. The free surface is effectively influenced by the porosity coefficient of girder. |

| Keywords: | multiple boundary element method sloshing girder with porosity time domain nonlinear |
