Intelligent Control System for Ceramics Ball Test Rig
An intelligent control system for ceramics ball rolling contact fatigue test rig based on LabVIEW was designed. The system consists of four functional blocks, which are data acquisition block, signal processing block, state recognition block and diagnosis decision-making block. The data in the test process such as load, vibration, speed, fatigue life and so on, are collected and recorded automatically. This system can alarm or shutdown once the test rig state is abnormal or the truncate time is satisfied. By using wavelet transform and other methods in the vibration signal processing and analysis, the failure parts can be detected accurately according to the spectral characteristics and the fault characteristic frequency of the parts. The intelligent control system has practical advantages. The high precision, fast response, low cost, accurate judgment and convenience manipulation are very desirable for ceramics ball rolling contact fatigue experiment.
