MWMOTE-MLLM: A cluster-level difficulty-aware oversampling multimodal large language model framework for imbalanced fault diagnosis of rolling bearings in horizontal reactors

The horizontal reactor serves as a critical piece of equipment in petrochemical production and operates under extreme conditions, including high temperature, high pressure, and strong corrosion. Under such conditions, rolling bearings are prone to faults caused by excessive vibration and lubrication failure, which may...
