Rolling Bearing Dataset

This rolling bearing dataset was collected using the QPZZ-II rotating machinery fault simulation test rig developed by Jiangsu Qianpeng Diagnostic Engineering Co., Ltd. The bearing used in the experiment was model NU205EM. An electromyographic-type acceleration sensor was used in this experiment, which was placed in the horizontal X and vertical Y directions of the bearing housing on the test rig. Under the conditions of a rotational speed of 1200 r/min and a sampling frequency of 5120 Hz, normal state (Norm), inner ring fault (IRF1, IRF2), rolling body fault (BF1, BF2), and outer ring fault (ORF1, ORF2) were collected.

本滚动轴承数据集采用江苏千鹏诊断工程有限公司研发的QPZZ-II旋转机械故障模拟测试台进行收集。实验中所使用的轴承型号为NU205EM。实验中采用了肌电图式加速度传感器，并将其置于测试台轴承座水平X轴和垂直Y轴方向。在转速为1200转/分钟和采样频率为5120赫兹的条件下，收集了正常状态（Norm）、内圈故障（IRF1, IRF2）、滚动体故障（BF1, BF2）和外圈故障（ORF1, ORF2）的数据。
