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
