摘要
基于势流理论,建立波浪与摆式波能转换装置作用的三维频域分析模型。应用数值模型对两种质量的摆式波能转换装置进行水动力分析,在考虑粘性阻尼作用的条件下,计算传动系统的最优扭阻系数。在最佳工况下,开展了波浪频率对摆板运动响应和俘获能量影响的系统研究,给出了波浪最佳频率范围、摆板振幅、能量俘获效率以及摆板表面的波动压强。
Based on the potential theory, a 3D frequency-domain model is set up for the simulation of wave interaction with pendulum wave energy converters ( WECs) . Hydrodynamic analysis is carried out for characteristic parameters of two WECs with different mass, and optimism power take-off ( PTO) torsional damping coefficients in consideration of viscous damping actions are obtained. Then on the foundation of the above best condition, systematic examination is carried out for the influence of incident wave frequency on body response and captured wave energy, and the optimism wave frequency ranges, amplitude, capture efficiency and fluctuating pressures on the pendulum plates are simulated.
