【摘要】 文章利用拉格朗日方程推导了含惯性摆波能发电装置之浮标在规则波作用下的七自由度运动方程。为了验证所推导公式的正确性,制作了一个物理模型,并对无负载阻尼工况在水槽中进行了模型试验。借助商业软件AQWA-LINE计算浮标的附加质量、辐射阻尼系数及波浪扰动力。利用文中推导的方程,计算了浮标及摆锤的运动响应,并将理论计算得到的结果与实验结果进行了比较。最后,分析了负载阻尼系数对浮标纵摇运动、摆锤纵摇运动、摆锤相对纵摇运动及波能转换效率的影响。更多还原

【Abstract】 Seven differential equations of motions which are used to describe the behavior of a buoy with inertial pendulum wave energy extractor in regular waves are derived by application of Lagrange equations.To verify the validity of the theoretical formulas derived, a physical model was developed, and the model tests for the case in the absence of power take-off damping in regular waves were conducted in a wave flume. The added mass, radiation damping and the wave exciting forces on the buoy are obtained by commercial software AQWA-LINE. Based on the derived equations, the motion responses of the buoy and the inertial pendulum are calculated, and the theoretical results are compared with the experimental results. The influence of the power take-off damping on the pitch motions of the buoy and pendulum, relative pendulum oscillation as well as the wave energy conversion efficiency is discussed.更多还原
