摘　　要：本文基于前期对振荡浮子式波能发电装置的研究,提出一种与采油平台结合的新型波浪能发电装置,并采用水动力学软件Ansys-AQWA进行数值模拟,计算了不同波况条件下的发电装置受力与运动响应。分析发电装置稳定性和输出功率表明：在振荡浮子与采油平台导管架相结合的状态下,装置运行正常,平台稳定,波能利用率并未受到显著影响,初步验证了设计的可行性。通过频域计算,发现装置发电理想波频区间为1.2~2.0Hz;通过时域计算,发现浮子垂向平均最大位移、最大速度、最大加速度与波浪波高成正相关,垂向平均最大加速度与波浪周期成负相关,垂向平均最大波浪力与波浪周期成正相关,上述成果将为后续研究与试验提供一定的数据支持。Based on the former studies on oscillating-buoy type wave energy converter,a new wave energy converterwas proposed in the present paper,which is combined with the oil platform.The hydrodynamic software Ansys-AQWA was employed to carry out all the numerical simulations.The forces on the device and corresponding movement responses were calculated under various wave conditions.The stability and output power analysis indicates：the operational stabilities of the wave energy device and platforms are good.The wave energy absorption ratio is not affected by the platform,which has demonstrate that the feasibility of the proposed design.It was found that 1.2~2.0Hz is the optimal wave frequency zone.On the other hand,the vertical mean maximum movement,maximum velocities and accelerations are in the positive correlation to the incident wave height.The vertical mean maximum accelerations are in the negative correlation to the incident wave periods.In addition,the vertical mean maximum wave forces are in the positive correlation to the wave periods.The above results will provide sufficient data support to the further studies.
