本文介绍了一种适用于风洞实验中浮子系统动力学仿真的半实物实验装置的实现方法和技术问题。所提出的工作是基于浮动海上风力机比例模型的具体应用，即使该方法也适用于一般的浮动系统，受到风和海浪的同时作用。该装置基于两自由度系统，提供浮动系统沿浪涌和俯仰的运动。参考HIL测试方法的实施，深入分析了以下主题：比例问题、数值问题、机械系统特性、力校正、测量和信号处理。对于这些主题中的每一个，都介绍了方法方法，并描述了技术问题。然后报告了一组结果，以显示这种实验装置在不同海况下的有效性：静水、规则波和不规则波。
This paper presents the methodological and technical aspects of the implementation of a hardware-in-the-loop experimental setup, suitable to simulate the dynamics of a floating system in wind tunnel experiments. The presented work is based on the specific application of a floating offshore wind turbine scale model, even if the approach holds also for floating systems in general, being subjected to the simultaneous action of wind and waves. The setup is based on a two degrees-of-freedom system, providing the motion of the floating system along surge and pitch. With reference to the implementation of the HIL test methodology the following topics are thoroughly analyzed: scaling issues, numerical issues, mechanical system characterization, force corrections, measurement, and signal processing. For each of these topics the methodological approach is presented, and the technical issues are described. A subset of results is then reported to show the effectiveness of such experimental apparatus, for different sea states: still water, regular, and irregular waves.
