Intelligent bearing tester using labview

摘要

This paper presents the development of an intelligent and low-cost vibration monitoring and fault diagnostic system using Lab VIEW. The intelligent System is built with the aid of software LabVIEW 7.1 and DAQ card PCI-6042E for testing bearings with reference to the standard bearing. Both the bearings are connected to the common shaft of the vibrating segment and vibration analysis is carefully carried out using a piezo-electric sensor with advanced charge amplifier. The vibration signals from the standard and the bearing under test are signal conditioned and connected to the Terminal block (BNC-2120) at two different channels. Analysis is done with a LabVIEW based software program for the Time and Frequency domain study. The comparison between the standard and test bearing is studied based on the Fundamental and multitones of the signal from its random behavior in the frequency domain. The results and recommendations are displayed according to the condition of the bearing with an allowable tolerance. This paper has enlisted different varieties of bearings after the careful study in the nearest industry. If this unit could be fabricated in mass production, it could be a low cost version of the "Intelligent Bearing Testing System".
