17 Jan Establishing mathematical model to predict ship resistance forces
Abstract: Resistance forces of water affecting to the ship hull at every single time during ship motions change very complexly.
For simulating the ship motion in 6 degrees of freedom on a bridge simulator, these forces need to be calculated. Previous studies
showed that resistance forces were estimated by empirical or semi-empirical methods, basic hydrodynamic theory has not solved
all components of resistance forces. Moreover, for simulating the ship motions at the initial design stage when experimental
value is not available it is necessary to estimate resistance forces by theoretical method. Fully estimating damping forces by
theoretical method is a practical challenge. This study aims to find out general equations to reasonably estimate all damping
coefficients in 6 degrees of freedom for simulating ship motions on bridge simulators.
