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（SHIVER）的第二次试验批次，于2023年春季在阿尔托大学冰波试验水池（Ice and Wave Tank）中开展。本次水池试验旨在获取模型冰环境下的冰作用、冰-结构相互作用、冰相似缩尺以及实时混合仿真（real-time hybrid simulation）局限性相关数据，以优化海洋结构物（如海上风力发电机组、灯塔或航标）的冰致振动模型试验。
该试验采用了混合试验技术，该技术已在SHIVER项目的第一次试验批次中使用（详见相关出版物、详见本数据集页面）。对试验装置进行小幅修改后，可测试吃水线处不同直径与形状的下部结构，并提升了数据可靠性。
此外开展了专项试验，以探究硬件在环（Hardware-in-the-Loop）试验装置的局限性。通过对结构模型进行缩尺处理，触发实时混合仿真的失稳现象。本次试验采用的缩尺方法详见已发表的独立期刊论文。
