摘要本文提出一种新型双体波浪能转换装置，其主体由浮标和可调节质心的摆体构成。利用AQWA进行频域仿真，获取装置的水动力参数，建立含黏性项的多自由度耦合的时域模型，并将水动力参数代入模型，分别开展规则波、不规则波的仿真，研究质心位置、PTO（Power Take-Off）阻尼对装置性能的影响，最终根据真实海况划分若干不规则波并分别开展仿真，研究装置在真实海况下的发电性能。结果表明：装置可通过调节配重位置在不同周期的波浪中高效发电，且装置在小波高情况下也可以有效利用波浪能量，具有持续的发电能力。

Abstract：This paper proposes a novel two-body wave energy converter (WEC). The WEC is composed of a buoy and a pendulum with a moveable mass block. A frequency-domain model was established by AQWA to calculate the hydrodynamic parameters of the WEC. A time-domain model with viscous terms and coupling of multi-degree-of-freedom was established. And the hydrodynamic parameters were substituted into the model. Then the simulation of regular and irregular waves was carried out respectively through the time-domain model to study the effects of the mass block position and PTO damping on the WEC. Finally, according to the real sea conditions, several irregular waves are simulated respectively to study the power generation performance of the WEC under the real sea conditions. The results show that: the WEC can generate power efficiently in waves of different periods by adjusting the position of the mass block, and the WEC can effectively utilize wave energy under the condition of wavelet height and has continuous power generation capacity.

Key words： wave energy converter two-body point absorber multi-DOF coupling nonlinear model irregular wave
