液舱内的晃动可能导致船舶不稳定或结构损坏。为了抑制液体晃动和防止贮箱损坏，通常采用内部结构。为增加消能效果，减小结构受力，设计了一种水平开孔板，并将其安装在矩形贮液池中。进行了不同振幅和频率下的试验研究，并对一个内埋水平穿孔板的储罐进行了激振。仔细检查了侧壁上的自由表面高度和共振频率。实验结果表明，水平穿孔板能有效地抑制水平激励下贮箱内的剧烈共振晃动。
Sloshing in a liquid tank may result in ship instability or structural damage. Inner structures are often used to restrain liquid sloshing and prevent tank damage. To increase energy dissipation and reduce the forces acting on structures, a horizontal perforated plate was designed and incorporated into a rectangular liquid tank in this study. Experimental studies were conducted, and a tank with an inner submerged horizontal perforated plate was excited under different amplitudes and frequencies. The free surface elevations on the side-walls and the resonant frequencies were carefully examined. The experimental results indicate that the horizontal perforated plate can significantly restrain violent resonant sloshing in the tank under horizontal excitation.
