Ball Rolling

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.

Main Components

LaB6 emitters are becoming increasingly popular as direct replacements for tungsten filaments in the electron guns of modern electron-beam instruments. These emitters offer order of magnitude increases in beam brightness, and, with appropriate care in operation, a corresponding increase in source lifetime. They are, however, an order of magnitude more expensive, and may be easily damaged (by improper vacuum conditions and thermal shock) during saturation/desaturation operations. These operations typically require several minutes of an operator's attention, which becomes tedious and subject to error, particularly since the emitter must be cooled during sample exchanges to minimize damage from random vacuum excursions. We have designed a control system for LaBg emitters which relieves the operator of the necessity for manually controlling the emitter power, minimizes the danger of accidental improper operation, and makes the use of these emitters routine on multi-user instruments.Figure 1 is a block schematic of the main components of the control system, and Figure 2 shows the control box.
