Abstract

Wave response experiments were performed to estimate the performance of three kinds of coupled system consisted of an elastic plate, a rigid plate and a fixed plate respectively. Vertical displacements, accelerations and wave pressures were measured on each plate model subjected to harmonic waves. The vertical displacements were measured using laser type sensor, acceleration responses were measured using high-sensitivity sensor for elastic and rigid plates at 9 locations respectively. And wave pressure distributions were measured using very small type pressure sensor that was built to order. Especially, regarding wave pressure, first of all wave pressure distributions on rigid and fixed plates were measured and compared with the past results. After that characteristics of wave pressure distributions on elastic plate were investigated from various point of view.
