Simulación numérica de un sistema mecánico pasivo de reducción de rolido para un barco utilizado en actividades de turismo o pesca.

Abstract

The present work comprises a numerical and parametric study to determine the technical feasibility of a passive roll compensation system. The system studied includes a ship, suspension lines and suspended plates. A parametric study shows that the main factor to take into account when reducing the roll of a ship is the pulling force it has. A numerical model of a system of plates of different sizes were designed to analyze the behavior of the vessel with each of these models and to observe how each size of plate influences its drag coefficient. By means of the application of spectral models, simulations were carried out in the ANSYS AQWA program simulating wave characteristics for each plate system and determining which plate size allows a better reduction of roll. Therefore, it is concluded that passive systems are very useful for ships because they increase the dragging force of the whole system, which implies an improvement in its stability that guarantees the safety and comfort of the structure and its occupants.
