Implementation Of Elastic Hinge For Structural Slender Ship Model Test In Towing Tank

With increasing demand for rapidly sea transport, it is needed to overcome the constraints related to vessel low speeds. This demand appears mainly in the Millitary and passengers-carrying fields, which necessitates the need to high speed mono-hull or multi-hull vessels. With increase in the size and speed of the vessels, the need to develop an understanding of the structural dynamic loads and structural flexible responses is felt. The most important issues that the designers are interested in them are extraction of the bending moments and shear forces and also the forces induced by slamming effect. Among the different methods available for prediction of the affecting forces and structural responses full scale model test, numerical methods and scaled model test can be mentioned.
Hydroelastic method, rigid backbone method and flexible backbone method are used in testing the scaled models. In the backbone method, a continuous beam is attached to the model. The methods to implement the measuring equipments on the rigid and flexible beams are different from each other. In this study, dimensional characteristics of the applied elastic hinges in the flexible beams in the scaled test models are extracted and the way to implement them in order to perform the tests is described.
