This is a dataset publication with multiple measurements seperated into different .mat files created at the Institut für Fluidsystemtechnik (Cair of Fluid Systems) at the Technische Universität Darmstadt (Technical University of Darmstadt (https://ror.org/05n911h24)).The experimental data include dynamic characterisations of gas accumulators. The data was determined on a dynamic uni-axial test machine. Each measurement-file contains the measurement at a monofrequency harmonic excitation.This dataset publication also contains, in addition to the measurement files, an RDF (Resource Description Framework) 'METADATA.ttl' file in the RDF Turtle format containing some metadata of the measurements.The structure of the measurement- and RDF-data represent a interim stage on the way to FAIR measurement data and is therefore to be considered as work in progress.The different measurement files in the .mat format contain different time series and corresponding metadata. The various measurements differ in various parameters (e.g. excitation frequency, excitation amplitude, ambient temperature, etc.).The used RDF information model does not yet cover all the metadata stored in the various .mat measurement files.If you have further questions, please feel free to contact info*AT*fst.tu-darmstadt.de .Thank you.Yours sincerelyLICENSE NOTICE:This dataset is licensed under the 'CC-BY-4.0' License (https://creativecommons.org/licenses/by/4.0/)
