西储大学轴承实验数据（12Hz驱动端轴承全）.zip
【实例简介】西储大学轴承实验数据（12Hz驱动端轴承全），该实验台包括一个2 马力（1.5KW）的电动机，一个扭矩传感器/ 译码器，一个功率测试计,还有电子控制器(图中没显示) 。待检测的轴承支撑着电动机的转轴,驱动端轴承为SKF6205 ，风扇端轴承为SKF6203 ，下表中分别列出了两种轴承的几何尺寸和各部件的故障频率。轴承用电火花加工单点损伤，损伤直径分为（0.007英寸=7 mils =0.177 8 mm，0.014英寸=14 mils =0.355 6 mm ，0.021英寸=21 mils =0.533 4 mm，0.028英寸=28 mils =1.016 mm ，0.04英寸=40 mils =1.016 mm。（1英寸=25.4mm）其中，轴承外圈的损伤点在时钟:3 点钟、6 点钟、12 点钟3 个不同位置进行设置。电动机风扇端和驱动端的轴承座上方各放置一个加速度传感器用来采集故障轴承的振动加速度信号。振动信号由16 通道数据记录仪采集得到，采样频率为12 kHz，驱动端轴承故障还包含采样频率为48 kHz 的数据。功率和转速通过扭矩传感器/ 译码器测得。
