摘　　要：建立了适用于带减摇水舱的船舶运动性能的时域分析方法。在该方法中,船舶运动的求解采用三维时域势流理论,而减摇水舱的模拟则基于粘流理论。船舶6自由度运动速度作为减摇水舱的运动激励输入,另一方面,减摇水舱诱导的力/力矩作为外力/力矩输入船舶运动方程,将两者耦合同步求解。对一条带减摇水舱的海洋工程辅助船的运动性能进行了计算分析,并和水池模型试验进行了比较,两者吻合较好。建议的方法为船舶减摇水舱设计的评估以及优化提供了一种切实可行的分析手段。A method determining ship motion with anti-roll tanks in time domain was presented, in which potential and viscous flow theories were applied to the simulation of the ship motion coupled with fluid motion in the anti-roll tank. The 6-DOF motions of the ship were input to the anti-roll tank and used as motion exciting. On the other hand, the induced force/moment by anti-roll tank was added to the motion equations and referred to as external terms, and then coupled equations were solved in the time domain. Finally, roll motions of an OSV equipped with an anti-roll tank were computed and compared with model test results, and good agreements were found. The method presented in the paper can serve as a base for estimation of the anti-roll tank and its design optimization.
