Abstract

Hull loads and response, hydroelasticity effects on fast monohulls E. Jullumstr0 & J.V. Aarsnes Division of Marine Vehicles, Norwegian Marine Technology Research Institute, N-7002 Trondheim,, Norway ABSTRACT The dynamic response of a correctly scaled hydroelastic monohull is presented. An experimental techniques for proper modelling of the important structural parameters as mass distribution, stiffness and damping is outlined. Different sensor types were used to measure the shear forces and bending moments. Model tests have been carried out with a model of a 110 m full scale ship. The experimental results for bending moment and shear forces are compared with calculated results using the FASTSEA computer program. INTRODUCTION Dimensioning of large, high speed vehicles demand knowledge and methods to determine the limiting environmental loads, operational aspects and structural strength. To achieve
