PT900 Dual-rotor System Fault Simulator

Product Description：

Advanced Mechanical Bearing Gear Fault Simulator Test Bed is prone to mechanical damage to its internal components after prolonged use, leading to wear and failure. Therefore, it is necessary to perform feature mining, classification, and prediction of fault categories for rotating machinery such as bearings, gearboxes, and shafts. Vibration  signal analysis is the most widely used research method in the diagnosis of rotating machinery faults. By collecting  vibration acceleration signals from components such as gears and bearings with different damage conditions during  operation, machine learning methods are applied to classify and predict signals, and potential features of fault data  are excavated. The rotating machinery fault simulation test bench can simulate and reproduce common fault vibration signals of rotating machinery, making it difficult to extract early fault features for reproduction. With the development and improvement of machine learning technology, researchers have applied machine learning models to fault  diagnosis, improving diagnostic accuracy.
