In order to realise the intelligent navigation of autonomous navigation and control system of surface unmanned boat, this paper designs and realises an autonomous navigation and control system of surface unmanned boat by combining the Beidou satellite navigation system, which is designed by two aspects, such as the boat-carrying part and the shore-based part, etc. Under the action of satellite navigation system, it can realise two control modes, such as autonomous navigation and remote remote control, and can realise the target electric navigation and autonomous path planning navigation. Finally, combined with the test area, simulation simulation simulation of its route on the computer, to verify the feasibility of its autonomous collision avoidance, the results proved the feasibility of the system and the correctness of the trajectory planning, so that the efficiency of its navigation has been improved, and the realization of the surface unmanned boat's autonomous cruising.
Aiming at the influence of journal inclination Angle on water-lubricated bearings, a mechanical model of propulsion shafting bearing load was established by theoretical analysis and numerical simulation to analyze the bearing force. Then a water lubricated bearing model is constructed, and the distribution characteristics and rules of water film pressure are obtained by simulating the inclined water lubricated stern bearing. The change of vertical inclination Angle has no effect on the water film pressure distribution. At low speed, the change of inclination Angle has little influence on the water film pressure, while at high speed, the influence on the water film pressure is obvious. When the pressure reaches the peak, the water film breaks, which makes the bearing contact stress value more concentrated.
