摘要：An experimental methodology of tank test, which enables us to directly obtain speed of actual ship under waves just by experimental result of model test under corresponding same wave condition, is newly developed. One of features of the methodology are controlling propeller rotational speed, managed by a self-propulsion motor set on a model ship, as power plant system of actual ship rotates its shaft speed against fluctuations of load torque. We call the intelligent motor system as “Marine Diesel Engine Simulator.” The other feature is, under using the MDES and the Auxiliary Thruster System, making total external forces acting on model ship, similar to those of actual ship under corresponding wave conditions. In this study, three fundamental components of the developed methodology are introduced, mainly focusing on similarity laws between model and actual ship. Thus, experimental results by the methodology are discussed by comparing with the conventional experimental methodology and numerical predictions. Finally, significances of the developed methodology are referred.
