Abstract
In order to speed up the construction of ocean intelligence, improving the intelligent operation level of Underwater Vehicles is one of the current research directions. This paper takes the Variable Structure Underwater Vehicle (VS-UV) as the research object. Through statics analysis and direct navigation simulation analysis, it is verified that the VS-UV has the ability of large-range low resistance navigation and short-range stable operation. CFD simulation method was used to simulate the 6-DOF motion of the vehicle in the two states before and after the deformation for hydrodynamic calculation. The least square method was used to fit the data to obtain the hydrodynamic coefficient and establish the dynamics model. The comparison between simulation results and real navigation results proves that the method can be used to obtain a reliable model for the VS-UV.
