Frequency response function dataset of flexible and rigid rotor-foundation systems for dynamic substructuring
Listed in REDU - Unicamp Institutional Research Data Repository
This dataset provides experimental frequency response functions (FRFs) of a rotor-foundation system for the application and validation of dynamic substructuring techniques, including coupling, decoupling and virtual point transformations.
Description
The data were obtained from impact testing using accelerometers on an adjustable test rig, considering two configurations: a flexible rotor (6 mm diameter) and a rigid rotor (25 mm diameter).
Measurements were performed at the bearing supports for the structure alone and for the assembled system under multiple operating conditions. The dataset consists of MATLAB (.mat) files containing FRFs and associated frequency vectors, with measurement points distributed in three spatial directions. It enables direct use in modal analysis and rotor-foundation interaction studies.
