摘　　要：针对49 m远洋围网渔船的振动问题,利用有限元软件建立全船的有限元模型,分析整船的固有模态,对船舶进行实船振动测试,结合实测数据和数值模拟结果,分析找到该船振动过大的主要原因,提出相应的减振方案。对改造后的船舶再次进行测试,发现船舶振动得到了有效控制。Aiming at the vibration problems of the 49 m ocean purse seine fishing ship, a finite element model of the whole vessel was established to carry out modal analysis of the ship, and the vibration of the ship was measured. By comparing the experimental data and the numerical results, the main causes of intermittent vibration of the ship were analyzed, and some measures of vibration reduction were proposed. The vibration data of the ship after transformation were tested, showing that the measures of vibration attenuation are effective.
