摘要

The two-dimension problems of the interaction between waves and one, two and a series of deformable plates are discussed, respectively, in this"study. The fluid motion is described by the linear wave theory. The deformable plates are simplified as the one-dimensional beams with uniform stiffness and mass distribution. A boundary element method (BEM) is used to calculate the wave field. The Euler Bernoulli beam theory is used to describe the motion of the deformable plate, which is calculated on the basis of a finite element method (FEM) in combination with the BEM model. The numerical solutions are derived for the velocity potentials together with the displacements of the deformable plates. After the energy conservation is calculated to verity the numerical models, the effects of structural flexibilities and interval between deformable plates on the reflecting waves are investigated.
