Vibration dataset of main journal bearings in internal combustion engines 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..本数据集涵盖健康与故障状态下内燃机主轴承轴颈的振动特征信号，数据通过安装于内燃机轴承座上的三轴加速度计（tri-axial accelerometer）采集获取。受试内燃机按照美军标MIL-STD-810G的规范，被置于各类气候与运行工况环境中，并在最先进的气候振动试验箱内完成测试，以模拟真实应用场景。本数据集共包含超过500个文件，涵盖健康与故障轴承的样本，所有样本均在多种气候与运行工况下完成记录。鉴于目前尚无公开的同类数据集，本数据集可为研究人员与工程从业者验证其诊断算法及模型在真实内燃机工况下的性能，提供极具价值且可靠的基准测试资源。
