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..本数据集包含健康与故障主发动机轴颈轴承的振动特征信号，采用安装在内燃机轴承座上的三轴加速度传感器采集得到。 该内燃机依据MIL-STD-810G标准设定了多种气候与运行工况，并在当前最先进的气候与振动试验箱中开展测试，以模拟真实应用场景。 本数据集涵盖超过500份数据文件，包含健康与故障轴承样本，所有样本均在多种气候与运行工况下完成采集。 由于目前尚无公开可用的同类数据集，本数据集可为研究人员与工程从业者针对真实发动机工况验证其诊断算法与模型提供极具价值且可靠的基准。
