摘　　要：针对某大型耙吸挖泥船首制船试航时出现的艉部振动偏大的问题,在对其续造船进行设计时,对可能导致首制船艉部振动偏大的原因进行分析并采取改进措施,通过首制船与改进后的续造船实测振动数据对比分析,证实改进措施的有效性,为同类船型的设计提供借鉴和参考。The problem of excessive stern vibration occurred during the trial of the lead ship of a large trailing suction dredger.In the design of the follow-up ship,the causes for the excessive stern vibration were analyzed and the improvement design was taken.Through the comparative analysis of the measured vibration data of the first ship and follow-up ship,the effectiveness of the improvement measures was confirmed,and it provides a reference to the design for the same type of ship.
