Abstract This paper presents a power take-off concept for the Moored, Multi-float and Multi-Mode Wave Energy Converter, (M4 WEC), based on oil hydraulic technology. The study shows the importance of having low max-to-mean mechanical power ratios, preliminary to the design of the oil-hydraulic power take-off. It explores the characteristics of the M4 WEC in order to achieve these lower power ratios and shows their impact on the preliminary sizing of the power take-off equipment. The power take-off concept, on the other hand, is derived from previous case studies and adapted to the M4 WEC with incremental developments on the mechanical interface with the WEC prime mover or float system and on the power take-off hydrostatic transmission.

M4 波浪能转换器的液压取力器概念

摘要 本文提出了一种基于油压技术的系泊多浮式多模式波浪能转换器（M4 WEC）的取力器概念。该研究表明，对于油压取力器的设计而言，具有较低的最大平均机械功率比的重要性。它探讨了 M4 WEC 的特性，以实现这些较低的功率比，并展示了它们对取力器设备初步选型的影响。另一方面，取力器概念源自之前的案例研究，并在与 WEC 原动机或浮动系统的机械接口以及取力器静液压传动装置的机械接口上进行了渐进式开发，以适应 M4 WEC。
