Abstract: Aiming at the practical demand of deep ocean mining, the hydraulic station on the nodule collector was proposed to separate from the nodule collector and hydraulic station was designed as a floating body, relatively independent and suspended above the front of the nodule collector. Contour of floating body for polymetallic nodule concept vehicle (referred to as floating body) was designed, and its 3D model was established adopting SolidWorks. The hydrodynamic and computational model of the floating body was established, after simplifying the 3D model. Reynolds average navier-stokes algorithm (RANS algorithm) and turbulence model were applied, and drag data under the condition of different working conditions was obtained adopting fluid dynamics simulation and analysis software ANSYS CFX. Drag characteristic of floating body was studied adopting curve fitting function of Matlab, and the feasibility of contour design was verified.

Key words: deep ocean mining, contour of floating body, fluid dynamics simulation and analysis, drag characteristic
