摘要
A fully nonlinear numerical wave tank technique is utilized to simulate a submerged horizontal plate.The plate is supposed to bethin，rigid and very close to free surface of water at finite depth.At each time step the wave profile is traced by fourth order Runge-Kuttamethod and damping zone is used to absorb outgoing wave and let simulation perform long time.Smoothing and regridding method is adopted toremove high gradients of control nodes on free surface.Numerical validities of wave tank technique are compared with linear theory of wave ele-vation and hydrodynamic wave interaction with a half floating cylinder，and the results show excellent agreements.Time domain wave plate sim-ulation is carried out under the wave generated by wave maker.The free surface deformation，wave exciting force and Fourier analysis of waveplate interaction are carried out in time domain.It is found that for plate very close to free surface，strong nonlinearity occurs，which reveals the limitation of linear theory.
