THE SENSITIVITIES OF THE RESONANT FREQUENCIES OF SHIPS' HULLS TO CHANGES IN MASS AND STIFFNESS

During the design of a ship there is always a problem of predicting natural hull frequencies and mode shapes so as to take account of them and to design and lay out equipment accordingly. Prediction methods exist but it is not generally obvious what the designer can do to change frequencies and mode shapes to achieve an optimized arrangement. A procedure is presented here for frequencies in the lower vertical modes. It is shown that it is possible to make significant alterations in response if this type of analysis is done at the earliest stages of design when changes are still feasible.
