Data for the publication: Real-time hybrid simulations 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 real-time hybrid test setup, 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 real-time hybrid 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>Data uploaded in this repository is linked to a manuscript that is currently in review with Scientific Reports.Please be referred to the README.pdf file for more information about the data uploaded.Contact Tim C.

本数据集源自SHIVER项目（SHIVER）的第二次试验活动，于2023年春季在阿尔托大学（Aalto University）冰浪水池（Ice and Wave Tank）中开展。
本次水池试验旨在收集模型冰环境下的冰作用（ice action）、冰-结构相互作用（ice-structure interaction）、冰相似缩比（ice scaling）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（offshore structures，如海上风力发电机组、灯塔或航标）冰致振动的模型试验研究。
本次试验采用了SHIVER项目第一次试验活动中已使用过的实时混合试验装置（可跳转至论文链接、数据链接获取更多信息）。对该试验装置进行小幅修改后，即可测试不同直径与吃水线处外形的下部结构，并提升了数据可靠性。
本次试验还开展了专项实验以探究该实时混合试验装置的局限性，具体通过缩比结构模型触发实时混合仿真的失稳现象。本次采用的相似缩比方法在另一篇期刊论文中已有详细阐述。
