摘　　要：为了研究多液舱浮体的动力响应特性,基于势流理论进行多液舱浮体动力响应的频域分析。首先考虑不同的网格尺寸开展网格敏感性分析,随后针对规则波中单液舱浮体开展建模计算并与相关试验结果进行对比验证。最后分析多液舱浮体的动力响应特性,并探讨载液量及载液类型对浮体动力响应的影响。研究发现:液舱对浮体横荡的影响较小,对横摇的影响较大,垂荡响应与全系统自重有关;横摇响应曲线的峰值大小及峰值数量与液舱的载液类型存在一定关联。In order to study the dynamic responses of a floating body with multiple tanks,the frequency do-main analysis of the dynamic responses of a floating body with multiple sloshing tanks was carried out based on the potential flow theory.Firstly,the sensitivity analysis was carried out considering different mash sizes,and then the modeling calculations of the floating body with a single tank were carried out in regular waves and compared with the relevant test results.Finally,the dynamic responses of the floating body with multiple tanks were further analyzed,and the effects of liquid loading volume and type on the dynamic responses of the floating body were discussed.It is found that liquid tanks have little effect on the sway motions of the floating body,but have a great effect on the roll motions,and that the heave responses are related to the sys-tem weight while the values and numbers of the roll response curves are related to the type of liquid tanks.
