Abstract: As follow-up of former research forced vertical oscillation experiments have been performed to determine peak pressures and rise times for four metal wedges with different dead rise angles. These pressures have been measured as function of vertical oscillation speed, trim angle and forward speed. The results, in general, show that the peak values of the impact pressures are proportional to the squared value of the vertical speed, however, also the influence of forward speed appeared to be significant. In most of the existing mathematical models this relation has unsufficiently accounted for as shown here. Application of the prediction models in this respect is urgently required.
