SOME DEVELOPMENTS IN THE AREA OF STRENGTH AND VIBRATION OF SHIPS

Practical methods for the design of propulsors and evaluation of associated hydrodynamic phenomena have progressed rapidly in the recent years. Both model- and full-scale verifications are available to substantiate the theory. Those responsible for after body design of high-powered ships will particularly appreciate the tools available for initial design scrutinization. The interaction of hull and machinery structures has long been subject to uncertainty, and has--in view of lack of practical predictive means--been treated somewhat cursory on the basis of previous experience and overly crude predictors. The consequences of forecasting integral behaviour on this basis have been rather unfortunate in many instances. This paper describes primarily progress during the last two years in the areas of wave induced motions and loads, finite element technique, and propeller induced loads and propeller design. Various examples are given to reflect applications to hull as well as machinery structures. It also discusses in which direction further research efforts are pointed.
