Abstract:

In order to assess the security of the floating wave power generating device, the wave impact force on the primary floating body in extremely arduous condition was calculated. The linear wave theory and Morison equation were employed in the calculation. The finite element model for the wave-power generating device was established by adopting ANSYS software. During the simulation process, interface was utilized to convert the three-dimensional model to Workbench model. The displacement variety and harmonic driving response of the primary floating body with the wave impact force were obtained. The simulation results showed that the stress and displacement variety both reached their maximum values under the impact of the extreme wind and waves, while all within the required security range.
