Numerical Wave Tank for Study Seakeeping of Amphibious Vehicle

摘要：

　　Wave generation method and vehicle position achieving method are investigated.A numerical wave tank is made based on CFD to study seakeeping performance of amphibious vehicle.Wave is made by a board maker method and absorbed by a velocity boundary treatment.Vehicle position is achieved by solving rigid body motion equations.Moving boundary is realized by dynamic deformable grid,and free surface is captured by VOF scheme.The motion of vehicle advancing in regular head waves is simulated.Results of vehicle position and resistance indicate that simulations can achieve enough hydrodynamic characteristics to study seakeeping capacity.
