摘　　要：养殖水舱作为大型养殖工船鱼类生活繁殖的主要场所,其横摇晃荡对鱼类有重要影响。以全流域适鱼流速作为核心评估指标,通过数值仿真分析,从外部激励、制荡措施、舱室型式等方面对养殖水舱横摇激励下的适鱼性影响情况进行研究。围绕上述内容,重点探讨不同参数组合下的流场结构及其抑流和减晃作用机理,并给出能够指导实践的相关结论。As the main place for fish living and breeding in large-scale aquaculture ship,the horizontal sway of aquaculture tank has an important effect on fish.Taking the fish-suitability velocity of the whole basin as the core evaluation index,the effect of the fish-suitability under the rolling excitation of aquaculture water tank is studied from the aspects of external excitation,swing control measures and cabin type through numerical simulation analysis.Based on the above contents,the flow field structure and the mechanism of flow suppression and damping under different parameter combinations are discussed emphatically,and the relevant conclusions that can guide the practice are given.
