Numerical forecast of the operating performance of underwater robots in autonomous navigation mode

In this paper, the scheme design and sampling mechanism of observation-level ROV are completed, and the operational performance of underwater robots in autonomous navigation mode is predicted numerically. According to the sliding mesh theory, the numerical simulation of the self-walking performance of the ROV body multi-propeller coupling system is completed. Based on the method of transmitting multi-computational domain flow field data from the sliding mesh, the dynamic problems such as the full body and multi-propeller fully coupled motion in the direct flight and the lower submersion are calculated numerically, and the manipulation performance of the observation stage ROV in autonomous navigation mode is predicted numerically. The results show that its navigation and observation functions meet the design requirements.
