摘　　要：对一种海底铰接摆式波浪能转换装置进行了模型建立及控制优化。分析了装置的水动力特性,考虑黏性阻尼,研究了压载和负载阻尼的控制对装置的波能转换功率和效率的影响。指出对海底铰接摆式波能转换装置而言,由于多数周期附加转动惯量较装置本身的转动惯量大很多,因此压载控制对波能转换功率和效率的影响较小,而负载阻尼的控制则表现出较好的效果和可行性。Modeling and system optimization of a bottom-hinged flap-type wave energy converter are introduced in the present paper.Hydrodynamic analysis is conducted by taking the viscous damping into account and moreover,and the effects of water ballast and external power take-off damping variables on the power out and conversion efficiency are given. It is noted that in most cases the added moment of inertia is much larger than the intrinsic inertia for a bottom-hinged flap-type wave energy converter,and that the influence of the ballast control on the flap is less important. However,the effect of the power take-off damping is satisfactory and the optimal damping is given.
