Abstract:This paper presents the results of experimental research on random wave impact on a horizontal plate. The test wave is unidirectional and irregular wave. The experiments are carried out with perpendicular random waves (   = 0  ) and oblique random waves (  = 15  , 30  , 45  ), the significant wave heights H1/3 ranging from 7.5 to 20 cm with 2.5 cm increment, the peak wave periods Tp ranging from 1.0 to 2.0 s with 0.2 s increment, and the clearance of the model with respect to the significant wave height s/H1/3 ranging from 0.0 to 0.5 with 0.1 increment. Wave impact pressures are obtained by using wavelet analysis to remove noise signals from the dynamic responses of the instruments. The distribution characteristic is given for the impact pressures of the perpendicular and oblique waves along the underside of the plate. The influence of different incident wave parameters including the relative water height H1/3/d, the relative plate width B/L and the relative clearance s/H1/3 on the non-dimensional wave impact forces is discussed. ? 2010 by The International Society of Offshore and Polar Engineers (ISOPE).
