Data for the publication: Hardware‑in‑the‑Loop experiments in model ice for analysis of ice‑induced vibrations of offshore structures

These data refer to the second test campaign of the SHIVER project, conducted in the Ice and Wave tank of Aalto University in spring 2023.Basin tests were performed to gather data on ice action, ice-structure interaction, ice scaling and limitations of real-time hybrid simulations in model ice to improve model tests of ice-induced vibration of offshore structures (e.g., offshore wind turbines, lighthouses or channel markers).Tests were conducted with a hybrid testing technique, which already had been used during the first test campaign of the SHIVER project (go to publication, go to data). Small modification of the setup allowed to test substructures with different diameters and shape at the water line and improved data reliability. Specific experiments were conducted to investigate the limitations of the Hardware-in-the-Loop test setup. Thereby structural models have been scaled to initiate instability of the real-time hybrid simulations. The applied scaling method is explained in more detail in a separate journal publication.<br>Please be referred to the README.pdf file for more information about the data uploaded.Contact Tim C.

本数据集对应SHIVER项目的第二次测试试验，于2023年春季在阿尔托大学（Aalto University）冰浪水池中完成。本次水池试验旨在采集冰力学行为、冰-结构相互作用、模型冰尺度效应以及实时混合仿真在模型冰场景下的局限性相关数据，以优化近海结构物（如海上风力发电机组、灯塔或航道航标）冰致振动的模型试验研究。本次试验采用混合测试技术，该技术已在SHIVER项目的首次测试试验中得到应用（详见相关文献、相关数据集）。试验装置仅经过小幅调整，即可测试吃水线处不同直径与外形的结构子系统，并有效提升了数据可靠性。此外还开展了专项试验，以探究硬件在环（Hardware-in-the-Loop）测试装置的局限性：试验中通过对结构模型进行尺度缩放，触发实时混合仿真出现失稳现象。本次采用的尺度缩放方法已在另一篇期刊论文中进行了详细说明。如需了解本次上传数据集的更多细节，请参阅README.pdf文件。如需获取额外相关信息，请联系蒂姆·C·哈默（Tim C.
