摘要

With the developing increasing for the exploration and exploitation of Marine resources, the engineering application of autonomous underwater vehicle (AUV) has been developed rapidly in both military and civilian fields. Hydrodynamic characteristics are the basis of AUV path planning and motion control. In this paper, based on the designed AUV platform, the drag and moment are analyzed in the process of straight, horizontal and vertical oblique navigation based on the computational fluid dynamics (CFD) technology. According to the simulation results, the hydrodynamic coefficient is calculated for AUV during linear motion in light of regression analysis method, which lays a foundation for the subsequent AUV motion control work.
