摘要

At different damping coefficients and rolling motion excitation frequencies, the influence of the installation position of ocean kinetic energy converter on the power generating performance in underwater detection vehicles is studied using the Runge-Kuta method according to the nonlinear coupled equation of the hull and rocking pendulum established by Lagrange equation. The numerical simulation results show that when the installation distance (from the rotating center of the rocking pendulum to the barycenter of the vehicle) of the ocean kinetic energy converter is zero, under the excitation of rolling motion, the harvested energy is zero; when the installation distance is not zero, energy harvesting system shows the characteristics of a vibration system near the natural frequencies. It is also shown that the harvested power has a square relationship with the installation distance. And at each different frequency, there is a zero power point near the zero installation distance, which shows that the installation distance of the ocean kinetic energy converter should not be equal to zero. The zero-power installation distance is related to the excitation frequency and has nothing to do with the damping coefficient. The research results can provide a reference for the installation and deployment of ocean kinetic energy converters.
