摘　　要：基于波浪辐射/绕射理论,利用水动力分析软件AQWA研究两船在波浪作用下的运动响应特性,给出驳船受浮式生产储油船(FPSO)影响时的附加质量和辐射阻尼,分析了驳船的漂移力和运动响应。计算结果表明,当两船间距为5 m时驳船的附加质量比间距为10 m时的值大2倍多,驳船的附加质量和阻尼随着间距的减小逐渐增大;在间距30 m时,驳船的速度越小所受的漂移力就越大,并且驳船的横摇和首摇运动就越剧烈。Based on wave radiation/diffraction theory,the motion responses between two ships in the wave were considered by hydrodynamic analysis software AQWA.The influences of the Floating Production Storage and Offloading（FPSO） on added mass and radiation damping of the barge were discussed,and the drift forces and motion responses of barge were analyzed.The results show that when the distance between two ships is 5 m,the barge＇s added mass for the case is twice as much as the case when distance is 10 m,the added mass and damping will gradually increase when such distance reduces.The lower the speed of the barge,the smaller its drift force,and the more intense rolling and yawing motion would occur when distance is 30 m.
