摘　　要：本文基于计算流体力学,采用STAR-CCM+模拟双浮板与液舱晃荡的耦合运动,探究双浮板间距以及入水深度对自由液面的影响规律。结果表明,液舱在共振频率的激励下,双浮板的制荡效果随着间距的缩减以及入水深度的增加而显著提升,当间距小于2L/3的情况时,双浮板之间的相互作用显著增强,液面波高会随着时间的推移出现小幅度的上漂现象,并且这一现象会随着入水深度的增加而愈加剧烈。This study based on computational fluid dynamics(CFD),STAR-CCM is employed to simulate the coupled motion between the dual floating plates and liquid sloshing in the tank,analyzing the effects of plate spacing and submersion depth on the free liquid surface.The results indicate that under the excitation of resonant frequency,the anti-sloshing effect of the dual floating plates is significantly enhanced as the spacing decreases and the submersion depth increases.When the spacing is less than 2L/3,the interaction between the dual floating plates becomes notably stronger,leading to a slight upward drift of the free liquid surface wave height over time.Moreover,this phenomenon intensifies as the submersion depth increases.
