“…The research by Qi et al [5] indicates that the peak frequency of coupled acoustic radiation from the propeller-shaft-ship system coincides with the longitudinal modal frequencies of the hull, shaft system, and propeller. Zhang et al [6] discovered that longitudinal vibration is transmitted between the shaft and the hull through thrust bearings, and with an increase in bearing stiffness, the coupling effect between the shaft and the hull is enhanced. Ge [7] and Dong [8] analyzed the vibration response of the shaft system under various excitations, revealing that the vibration characteristics of the propulsion system are significantly influenced by the modal frequencies of the stern structure.…”

The stern structure of the ship, as the primary source of vibration and noise, has always been widely studied. Conducting an analysis of the vibration characteristics of the stern and determining the impact of local structures on the complex coupled vibration in the stern section are particularly important aspects of research. This paper employs the structural-acoustic coupling methodology to investigate the vibration features of the stern of a ship. The study explores the influence of variations in parameters such as the rudder, stern frame, and shaft system on the vibration response of the stern. The results provide valuable insights into controlling vibration and noise in the stern section of ships, as well as informing the design of related structures.
