Experimental study on the water impact load on symmetric and asymmetric wedges

Abstract

In the present study, the water impact loads on two-dimensional symmetric and asymmetric wedges are mainly studied. The impact pressure and forces are measured during the vertical drop of the symmetric and asymmetric wedges. The drop velocity of wedge is evaluated from the measured acceleration and displacement. The measured pressures are compared with the analytic solutions. The measured forces at local area of wedge are compared with the pressure integral and analytic solutions. Some findings on symmetric and asymmetrical wedge drops are presented and the reliability of force sensor for the measurement of local impact force is discussed.
