Point-Absorbing Wave Energy Converter Based on Nonlinear Pendulum Stiffness Mechanism
摘要
Abstract
In order to achieve stable capture of ocean low-frequency wave energy,a point-absorbing wave energy converter based on a nonlinear pendulum stiffness mechanism was designed.A compact pendulum stiffening device was constructed through addition of simple tensile elastic elements between the pendu-lums.The force analysis of the nonlinear stiffness structure was carried out the time domain dynamic model of the nonlinear wave energy converter was established based on the Cummins equation,and the wave energy conversion characteristics of the point absorption wave energy converter under the action of regular waves were analyzed.Numerical simulation shows that through introduction of an appropriate nonlinear pendulum stiffness mechanism,the motion response of the system under wave excitation can be improved,and the frequency corresponding to the peak motion response of the system under wave excita-tion can be reduced,thereby improving the system's capture efficiency of low-frequency energy.关键词
