Rocking Conversion System Based on Wave Energy for Unmanned Underwater Vehicle

Abstract:

Aiming at the navigation purpose of long time and large distance of UUV( unmanned underwater vehicle), and dealing with the energy demand of UUV for long continuous work, on the basis of analysis and comparison of existing wave energy converters at home and aboard, a rocking energy generation device based on the wave energy is proposed. The equations of motion for the vehicle and the rocking pendulum are established according to Lagrange method. Finally, the factors affecting the rocking generation performance are analyzed by solving the simplified equation of motion according to the Runge-Kutta method. The influence of parameters on the rocking generation is investigated over a range of sea state. Research and analysis show that the proposed wave energy rocking generation device model is reasonable and feasible, and provide a theoretical basis and reference for the development, the engineering test and the optimization of the rocking generator.
