SLAMMING OF RIGID WEDGE-SHAPED BODIES WITH VARIOUS DEADRISE ANGLES

Abstract

An experimental investigation of rigid body slamming was performed by dropping one flat-bottom steel model and five wedge-shaped steel models with small deadrise angles (from 1 to 15 deg) from various elevated positions above a calm water surface. Recording instrumentation was capable of picking up and recording frequencies from 0 to 200 kc, which covered the frequency range of the hydrodynamic as well as the acoustic pressures that might act on the model. From the test results, a set of charts is provided to predict the maximum impact pressures due to slamming of rigid wedge-shaped bodies. (Author)
