摘要：

Based on the finite element method (FEM) and boundary element method (BEM), the coupled vibration truncation model of propeller-shaft-hull structure was established to analyze the influence of propeller excitations in different directions on the vibration and acoustic radiation of the stern structure.The research shows that the vibration response peak of the hull structure is similar to the natural frequency of blade passing frequency (BPF) or stern structure by propeller excitations.The characteristics of the underwater radiated noise of the stern structure change obviously with the frequency, the radiated noise of the stern structure is distributed evenly along the ship length when the frequency is low.With the increase of frequency, the local acoustic radiation characteristics of stern structure get significantly enhanced.The vibration and acoustic radiation is mainly caused by horizontal force of propeller. © 2020, Editorial Board of Journal of Huazhong University of Science and Technology.
