Twin-Spool Rotor Misalignment, Looseness, and Rub-Impact Vibration Dataset

This dataset comprises raw vibration data acquired from a twin-spool rotor system under ten operational conditions: Coupling misalignment, HP disk 1 rubbing, LP disk 2 rubbing, Bearing pedestal 1 looseness, Bearing pedestal 1 looseness and LP disk 1 unbalance, Bearing Pedestal 1 Looseness and HP Disk 1 Rubbing (Rubbing clearance changes), Bearing Pedestal 1 Looseness and LP Disk 2 Rubbing (Rubbing clearance changes), Coupling misalignment and LP Disk 2 Rubbing (Rubbing clearance changes), Coupling misalignment and HP Disk 1 Rubbing (Rubbing clearance changes), Coupling misalignment and LP Disk 2 Rubbing (Misalignment amount changes). For each condition, data were collected under varying speed ratios and rotational speeds. All data files are annotated in the “data label.xlsx” file.
