摘　　要：对于液货船舶,航行过程中液舱晃荡不可避免,采用合理的液舱结构对减小液舱晃荡压力至关重要。基于传统的矩形液舱考虑在纵舱壁上添加不同宽度和数量的水平挡板及顶部削斜2种型式,建立了船舶液舱的三维模型,并利用Fluent软件进行三维液舱的晃荡压力计算,评估液舱结构型式对晃荡压力的影响。计算表明,在较高装载率下,通过合理设置挡板的数量和宽度,可以使舱内的晃荡情况得到优化,而顶部削斜结构型式由于减小了沿晃荡方向的舱体长度,可有效降低高装载率下的晃荡压力。For liquid cargo ship,tank sloshing is inevitable during navigation.It is very important to adopt a reasonable tank structure to reduce the tank sloshing pressure.Based on the traditional rectangular tank,considering adding horizontal baffles with different widths and numbers on the longitudinal bulkhead and the top cutting,the three-dimensional model of the tank is established,and the sloshing pressure of the three-dimensional tank is calculated by using Fluent software to evaluate the influence of the tank structure on the sloshing pressure.The calculation shows that under high loading rate,the sloshing situation in the cabin can be optimized by reasonably arranging the number and width of baffles,and the sloshing pressure under high loading rate can be effectively reduced by reducing the length of the cabin along the sloshing direction with the one of the top cutting.
