Abstract:The predictions of wave-induced hull girder hydroelastic vibrations and bow flare slamming loads are important for structural strength and load response issues during ship design and construction.The classical small-scale ship model wave load tests in the towing tank are associated with limitations such as pronounced scale effects, artificially generated waves, and limited model navigational range.The self-propelled large-scale model wave loads testing technique was proposed in this paper.The experimental setup and data analysis method were described in details.The design of backbone for the segmented model and vibration modal results were reported at first.Then wave-induced hull hydroelastic vibrations and impact loads were analyzed based on the large-scale model sea trial measurement data.The bow slamming loads and global whipping responses of hull in three-dimensional waves were finally analyzed.
