Abstract: For the stern area harmful vibration problems of the first river electric propulsion luxury cruise ship, the simulation calculation for ship whole and local structure was carried out by MSC PATRAN software; the overall structure and local excitation source, vibration mode and natural frequency were studied. Comparative analysis was carried out between the experimental data and the measured data, which verified the reliability of the theoretical analysis and numerical simulation. Furthermore, the causes in terms of vibration problems were summarized, and the corresponding ship vibration optimization measures were put forward.

Key words: ship engineering, ship harmful vibration, simulation analysis and calculation, ship vibration reduction
