THE INFLUENCE OF VIBRATIONS ON THE STRENGTH OF SHIPS

Vibrations on ships are of interest not only with regard to their effects on passengers and crew, instruments and equipment, but also because of their influence on the strength of the ship's structure. In a number of cases structural damage, e.g. cracking has been observed after a very short operational life of the ship. The paper deals with the theoretical background of damage of this type and the possibilities of theoretical analysis at the design stage. The practical example of the afterbody of a ship excited by the propeller is used to illustrate the present status of the analysis of forced vibrations. A finite element model consIsting of 3,400 elements with 4,000 degrees of freedom is used for the analysis.
