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.本数据集包含从双轴转子系统（twin-spool rotor system）采集的原始振动数据，涵盖10种运行工况：联轴器不对中（Coupling misalignment）、高压盘1碰摩（HP disk 1 rubbing）、低压盘2碰摩（LP disk 2 rubbing）、轴承座1松动（Bearing pedestal 1 looseness）、轴承座1松动伴低压盘1不平衡（Bearing pedestal 1 looseness and LP disk 1 unbalance）、轴承座1松动伴高压盘1碰摩，碰摩间隙可变（Rubbing clearance changes）、轴承座1松动伴低压盘2碰摩，碰摩间隙可变、联轴器不对中伴低压盘2碰摩，碰摩间隙可变、联轴器不对中伴高压盘1碰摩，碰摩间隙可变、联轴器不对中伴低压盘2碰摩，不对中量可变（Misalignment amount changes）。针对每种工况，均在不同转速比与转速条件下采集数据。所有数据文件的标注信息均存储于"data label.xlsx"文件中。
