摘要：
The current model experiments for ship wave loads are tested in laboratory tanks. However, the hydrodynamic behaviors of full-scale ships cannot be fully reproduced by tank models due to the limitations of tank size, wave production capacity, model sailing range and scaling effects. In fact, real ocean waves are characterised by strong nonlinearity, randomicity and broad directional spreading. Therefore, it is of great significance to investigate the ship hydrodynamic behavior in actual sea waves. The novel testing technique, which includes performing large-scale model test at sea, combines the advantages of tank model test and full-scale sea trial. This paper presents the large-scale model testing technique for ship wave loads and slamming loads measurement. A suite of large-scale model testing system was established and the wave load experimental scheme at sea was proposed. Moreover, the ship motion and load responses and slamming load behavior in actual severe seas are analyzed based on the large-scale model measurement data. © 2021, Editorial Board of Journal of Ship Mechanics.
