摘　　要：针对 35 0 0 0吨油轮艉部导管产生裂纹 ,该文采用有限元法和流体边界元法对船舶艉部导管进行振动性能预报 ,并结合振动试验 ,为减少导管的振动提供了良好的手段 ,并取得了一定的效果。This paper presents a study on the prediction of vibration characteristic of ship stern duct , that was carried out by using the finite element method and fluid boundary element method ,aiming to solve the crack problem of a 35000dwt oil tanker's stern duct . Based on computation and vibration test , measures for depressing the vibration was provided and gave a good effect .
