M001 - GVT Data and Nastran models (August 2024) (Models based on the publication: Effect of Wing Stiffness and Folding Wingtip Release Threshold on Gust Loads)

GVT Data and Nastran models of five wings with a flared folding wingtip, featuring different stiffness properties.The GVT data is the modal test input file automatically generated by NX/Simcenter when importing modal data from Simcenter TestLab. It contains the position of the sensors and the different mode shapesThe Nastran models are based on the models of the original publication but have been generated using different modelling techniques. These new models (Original) are updated using the model update procedure in Simcenter to achieve better correlation with the GVT data (Updated).

本数据集包含五款带有扩折式翼尖的机翼的地面振动试验（GVT）数据与Nastran模型，各机翼具备不同的刚度特性。其中GVT数据为NX/Simcenter从Simcenter TestLab导入模态数据时自动生成的模态测试输入文件，包含传感器位置与不同振型。Nastran模型以原始发表文献中的模型为基础，采用不同的建模技术生成；这些新模型（Original）通过Simcenter内置的模型更新流程进行更新，以实现与GVT数据（Updated）更优的相关性。
