Acceleration signals of rolling element bearings with artificial defects

This dataset includes the acceleration data acquired during an experimental study on rolling element bearings characterized by artificial defects on the outer ring. Signals were acquired for a number of operative conditions. These were characterized by different values of applied load, shaft rotation frequency and defect dimension. The uploaded files include: - a .rar archive containing all the acceleration signals as .txt files; - a readme file in .pdf format which contains information about the test bench, the test conditions and how to interpret the .txt files.本数据集包含针对外圈带有人工缺陷的滚动轴承（rolling element bearings）开展的实验研究所采集的加速度数据。研究针对多种运行工况采集了相关信号，各工况的区别在于施加的载荷、轴旋转频率以及缺陷尺寸的取值存在差异。上传文件包含以下内容：- 一个.rar压缩归档文件，其中以.txt格式存储了全部加速度信号；- 一份.pdf格式的说明文档，其中包含了试验台、试验工况以及如何解读.txt文件的相关信息。
