Data for "Load application in wind turbine blades modelled as reduced-order multibody structures in the floating frame of reference formulation"

<p dir="ltr">This dataset includes the input and result files of the isotropic beam numerical models used for the paper "Load application in wind turbine blades modelled as reduced-order multibody structures in the floating frame of reference formulation", as well as the scripts used to produce the plots in the paper.</p><p dir="ltr">In this paper, a method for transferring distributed loads calculated by BEM-based aerodynamic codes to a multibody reduced-order model based on the floating frame of reference formulation (FFRF) is presented. The model is based on solid finite elements and reduced using the Hurty/Craig-Bampton method and interface reduction based on interface modes. Two versions of this model are introduced to avoid applying loads to its internal DOFs, by including internal interfaces at the load application cross-sections, either described by interface modes (IM) or using a minimum strain energy (MSE) formulation. These are implemented in the general multibody dynamics code <a href="https://github.com/jgerstmayr/EXUDYN" rel="noreferrer" target="_blank">Exuydn</a>.</p><p dir="ltr">The following models are compared:</p><ul><li>Exudyn - Reduced-order FFRF model with interface modes</li><li>Exudyn - Reduced-order FFRF model with interface modes + IM load interfaces</li><li>Exudyn - Reduced-order FFRF model with interface modes + MSE load interfaces</li><li>Abaqus - Solid C3D20R elements</li><li><a href="https://www.hawc2.dk/" rel="noreferrer" target="_blank">HAWC2</a> - Beam elements-based FFRF model</li></ul><p dir="ltr">More information can be found on the "readme" file.</p><p dir="ltr"><u>List of individual files and licenses:</u></p><ul><li>Folder <b>plots</b>: © Technical University of Denmark 2025 <a href="https://opensource.org/license/mit" rel="noreferrer" target="_blank">MIT</a></li><li>Folder <b>models</b>:</li><li><ul><li>Subfolders <b>funcsExudyn</b> and <b>exudyn</b>: © Technical University of Denmark 2025 <a href="https://opensource.org/license/mit" rel="noreferrer" target="_blank">MIT</a></li><li>Subfolders <b>hawc2</b>, <b>abaqus</b> and <b>exudyn/results</b>: <a href="https://creativecommons.org/licenses/by/4.0/" rel="noreferrer" target="_blank">CCBY-4.0</a></li></ul></li><li><b>readme.md</b>: <a href="https://creativecommons.org/licenses/by/4.0/" rel="noreferrer" target="_blank">CCBY-4.0</a></li></ul><p><br></p>
