英文摘要：Nowadays, all hydrodynamic testing devices of model ship are planar motion mechanism, thus limiting the measuring range of ship hydrodynamics, while a new hydrodynamic testing device of model ship, the six-DOF hydrodynamic testing device can expand it. It is introduced in three ways:the works of six-DOF platform, the method for determining the range of six-component balance, the total design. Firstly, the works of six degrees of freedom platform is introduced in detail,. that the correspondence between the movement of the six sports bars on the platform and the six freedom movement of a ship. Then establishing preliminary equations to calculate the forces and moments of the six freedom movement, and determining the range of six-component balance in the experiment device on the basis of specific technical performance of the planar motion mechanism at home and abroad. Finally, the overall structure of the experiment device is determined and the shape and size of the existing ship pool trailer platform are designed. On this basis, the specific structure and size of the trailer frame, the three-dimensional schematic diagram, two-dimensional installation diagram and size diagram can be determined, considering forces of the trailer platform and installation of the trailer platform and six degrees of freedom platform, and do structural strength analysis.
