Abstract: To deal with the energy supply demands for marine UUVs， a small size pendulum power generation device was proposed. The devices were installed inside the UUVs， which were affected by waves， currents， tides and other factors， the vehicles swung to obtain the marine kinetic energies and converted them into stable electricity. The work principles，system structures and design schemes were described in detail， and the system electromechanical coupled dynamic simulation platform was established for simulation analysis，as well as the comparative verifications were performed by prototype tests.The results show that the design scheme is feasible， the power generation device may achieve stable power outputs， and the system effective power generation efficiency may reach to 24.40%.
