Hydroelastic experiment is an important method to investigate the hydroelastic response of ships. The state-of-the-art of the hydroelastic experiment of ships at home and abroad has been summarized, with focuses on the widely used segmented keel beam model, including the structural design, hydrodynamic module design, loading types and experimental result measurement. The applicability of different segmented keel beam models is then analyzed. The key technologies of the segmented keel beam model in the experimental design stage are summarized to provide the design indicators for the main contents based on the team experience, in order to provide references for the design of the hydroelastic experiment for ships.
