Bearing Fault Prediction System Design Based on LabVIEW

摘要

High-precision machine tools are important equipment of production line in general [1]. However, there hasbeen more difficult on failure prediction and maintenance of its spindle bearings. There are no timely replacement of thebearing when the failure occurs will result in decreased equipment utilization. This paper designed a set of bearing failureprediction system based on LabVIEW programming environment aiming at the need of the maintenance of machine toolspindle bearing in production line. The system will predict the bearing failure through the analysis of the size precision ofthe parts machined by bearing. The system mainly consists of two parts, data acquisition system and data analysis system.It has functions of data analysis and calculation, data storage and display and alarms, etc.
