摘　　要：减摇水舱是目前船舶最常用的减摇装置之一,目前研究水舱的主要方法是台架试验和船模模型试验。文章针对某型1 500 t船水舱做了岸上摇摆台试验,以确定减摇水舱的固有周期和规则波下的抗摇力矩。由于岸上试验耗时长、代价高,采用CFD数值方法对水舱的自由衰减和强迫振荡进行了仿真计算,通过与试验值对比发现,CFD计算结果吻合较好,证明了CFD方法在模拟水舱摇摆台试验中的可行性。Anti-rolling tank is the one of the most commonly used stabilizing equipment. Bench test and basin test are the main methods to study the tank. Bench test for 1500 ton ship is carried out to verify the natural period and the moment under regular wave. As time consuming is long and cost is high for bench test, the free-decay and forced oscillation phenomenon are simulated by CFD method, the computed results agree well with the conclusions drawn from the bench test data, which proves that the accuracy of CFD simulation can satisfy the requirement and provide faithful proof.
