| Abstract: | The paper studied the deck house local vibration mode analysis of ultra-large semi-submersible heavy lift vessel combined with the method of vibration excitation sources and the self arrangement characteristics by use of three dimensional FEM. The aim is to investigate the deck house vibration design techniques for initial design, and lower the vibration risk during the design phase. This paper provided a basic process and design method for similar deckhouse structure dynamic design. |
