To realize a small-sized floating-type wave energy converter, a vibrational power generator that utilizes the gyroscopic effect and a geared acceleration is presented. First, equations of motions of the spin accelerating mechanism are derived. Next, it is shown by the numerical analyses that the spinning velocity of the gyro-flywheel is accelerated by the rotating vibration, a steady-state small vibration with the frequency twice the input frequency exists in the flywheel spin, and the generated power is 10 W at the conditions that the flywheel diameter is 600 mm, the weight is 20 kg, the input frequency is 0.2 Hz and the amplitude is ±10 deg. Finally, an experimental apparatus of the spin accelerating mechanism with a flywheel of φ300 mm is developed to show that the experimental and calculated spin and precession velocities agree well.
