[摘 要] 在旋转类的机械部件中滚动轴承是特别容易出现故障的一个零部件，很多旋转类的机械故障都与滚动轴承有关。由于滚动轴承的设计存在问题，使用方法不佳，安装方法不当，使得轴承在使用了一段时间以后会出现很多种类的故障。因此，为了减少此类事情的发生，国内外已经掀起了一股研究滚动轴承故障的热潮，并且在现有的技术的状况下已经取得了显著的成绩并有良好的发展。而振动状态的分析是滚动轴承的状态监测和故障诊断最常用也是最重要的一种手段。为了进行振动状态的分析，设计故障诊断实验平台就显得极为迫切。39609
本文针对现有的滚动轴承实验台存在的优点与不足，提出了便于更换的滚动轴承故障诊断实验平台。以自行研制的实验平台为基础搭配MATLAB软件和WINDOWS操作系统，搭配传感器，信号采集卡进行分析。
本文设计的实验平台能够按照要求完成既定的任务，能够研究滚动轴承的故障类型并进行实验模拟，取得成功。

Roller Bearing Fault Diagnosis Test Platform Design
Abstract: Rolling is a rotary type machine parts most prone to failure of a part, a plurality of rotating machinery fault class and status are related to the rolling bearing. Because of the design problem and installed due to poor or rolling bearings Rolling in use for some time in the future there will be a variety of failures. Therefore, the home and abroad has set off a wave of Rolling to reduce such things from happening. Bearing Fault boom, and in the situation existing technology has made remarkable achievements and good development. The analysis of the state of the status of the rolling bearing vibration monitoring and fault diagnosis of the most common and the most important as a means. For the analysis of vibration state design fault diagnosis test platform becomes extremely urgent.
In this paper, the advantages and disadvantages of the existing Rolling bench, proposes convenience with the change of rolling bearing fault diagnosis experiment platform. With self-developed experimental platform based on MATLAB software with WINDOWS operating system with sensors, signal acquisition card for analysis.
This design of experimental platform in accordance with the requirements to complete a given task, to study the type of rolling bearing fault simulation and experiment to succeed.
Keywords: rolling; troubleshooting; vibration signal; experimental platform
