DESIGN STAGE CONSIDERATION (OF VIBRATION)
In this paper DnV experience of vibration problems from the design stage to full-scale measurement is summarized. Wherever possible, a review of the plans at the early design stage should be made. This may pin-point the areas of particular importance where further investigations are necessary. Both excitation sources and responses, i.e. global vibration of hull and superstructure and local vibration of decks and bulkheads are considered. The problems are discussed from the point of view of human suspectibility and fatigue cracks. In conclusion, some examples of the use of simple calculation methods and empirical data are given. The necessity of extensive finite element investigations for particular parts of the structure is mentioned. Order from: BSRA as No. 49,081.
