EXPERIMENTAL INVESTIGATION OF RIGID FLATBOTTOM BODY SLAMMING.
Abstract
An experimental investigation of rigid flat-body slamming was performed by dropping a 20-in. x 26.5-in. steel plate from various elevated positions above a calm water surface. Recording instrumentation was provided to pick up and record frequencies from direct current to 200 kilocycles, which covered the frequency range of the acoustic pressure that might act on the model. Because of the effect of the trapped air or cavitation between the falling body and the water, however, the maximum impact pressure measured was much lower than the pressure expected, if the generally accepted acoustic pressure formula is applied.
