摘要： 为解决浮式平台在环境复杂海域中的安全和工作性能问题,提出提高浮台稳性的措施。本研究将摆臂浮子式波浪能转换装置搭载到浮式平台上,建立摆臂浮子阵列与浮式平台的多体耦合水动力学模型,利用AQWA水动力仿真软件开展数值模拟和参数化分析,揭示摆臂浮子阵列与浮式平台稳性间的相互作用机理,获得摆臂浮子形状及数量、波浪周期对浮式平台稳性影响的作用规律,寻得最佳的摆臂浮子搭载方式。研究结果表明,搭载摆臂浮子后的浮式平台能更好地降低垂荡和纵摇的晃动幅度,半球型摆臂浮子相比圆柱和圆锥型摆臂浮子能明显地降低平台的纵摇幅度;摆臂浮子阵列数量的增加会逐渐降低平台垂荡和纵摇的晃动幅度;在给定波高、改变周期的情况下,搭载摆臂浮子后的浮式平台能明显降低平台垂荡和纵摇晃动幅度,但随着摆臂浮子数量的增加,平台稳性提高程度越不明显。因此,若只考虑平台稳性因素,可搭载少量的摆臂浮子降低成本,若考虑波浪能装置给平台供电因素,可搭载多量的摆臂浮子提高供能。

Abstract: In order to solve the problem of safety and working performance of floating platform in complex environment sea area, the measures to improve the stability of floating platform were put forward. The swing arm float wave energy conversion device was mounted on the floating platform, a multi-body coupled hydrodynamic model of the swing arm float array and the floating platform was established, and the AQWA hydrodynamic simulation software was used to carry out numerical simulation and parametric analysis to reveal the interaction mechanism between the swing arm float array and the stability of the floating platform, and the effect of the shape and number of swing arm floats and the wave period on the stability of the floating platform were obtained, and the optimal swing arm float carrying method was found. The results showed that the floating platform equipped with swing arm float could better reduce the sloshing amplitude, and the hemispherical swing arm float could significantly reduce the pitch amplitude of the platform compared with cylindrical and conical swing arm floats. The increase of the number of swingarm float arrays would gradually reduce the shaking amplitude of the platform. In the case of a given wave height and changing the period, the floating platform equipped with swing arm floats could significantly reduce the shaking amplitude, but with the increase of the number of swing arm floats, the improvement of platform stability was less obvious. Therefore, if only the stability of the platform was considered, a small number of swing arm floats could be equipped to reduce costs, and if the wave energy device was considered to supply power to the platform, a large number of swing arm floats could be equipped to improve energy supply.

Key words: wave energy, swing-arm float array, floating platforms, wave absorption and roll reduction, AQWA simulation
