Vibration Assessment of Ship Structures

Nowadays, noise and vibration problems tend to become an important part of the design process in the naval industry. Vibrations often affect the passengers comfort, but more dangerously may damage the structure, embarked merchandise and equipments. A simple way to avoid vibrations is to prevent the resonance conditions. The paper presents a study about the vibration of local structures (beam structures and stiffened panels) with application in the marine industry. The model has been implemented in FORTRAN into a numerical module and will be integrated in the near future with the LBR-5 generic stiffened structure optimization code.
