Main engine journal bearings vibrations dataset of automobile internal combustion engine under diverse climatic and varying operating conditions

The dataset includes vibration signatures from both healthy and faulty main engine journal bearings, captured with a tri-axial accelerometer mounted on the bearings' housing of an internal combustion engine. The engine was exposed to various climatic and operational conditions following MIL-STD-810G and was tested in a state-of-the-art climatic and vibration chamber to simulate real-world scenarios. The dataset comprises more than 500 files, with healthy and faulty bearings, each recorded under a range of climatic and operational conditions. This dataset is a valuable and reliable benchmark for researchers and practitioners to validate their diagnostic algorithms and models against real engine conditions as no such dataset is publicly available..
