This study focuses on the design and manufacturing methods of elastic scaled similarity models for large flexible wind turbine blades. Stiffness test results and modal test results of the scaled models were obtained via high-precision acquisition equipment. Ground modal tests and stiffness tests were conducted on the completed elastic scaled similarity models to collect their structural inherent characteristics, verify the error between test results and design values to ensure model accuracy, and generate data on the acceleration responses and deformation of flexibility control points of the models. The flexibility matrix derived from stiffness tests was compared with that obtained from simulations to analyze errors; the results of modal tests were compared with the modal frequencies and mode shapes calculated by software to analyze errors. The dataset mainly includes raw data of the models' acceleration responses and deformation of flexibility control points, data processing results, and relevant technical reports, with a total data volume of approximately 360 MB.
