Abstract:An intelligent measurement and control (MAC) system for friction and wear testers was developed by using the virtual instrument platform LabVIEW. The intelligent MAC system which takes a industrial PC as a core and integrates contains data acquisition, data processing, waveform display and environment control as a whole,realized the real-time detection of temperature, velocity, pressure ,torque and friction coefficient etc. It has extremely powerful and agile ability of data signal processing by the C subroutine embedded in LabVIEW, and provides a good platform for the future data processing. The friction and wear tester can simulate the actual working conditions, and carry out the friction and wear experiments under manifold kinetic modes.
Keywords:LabVIEW;friction and wear tester;measurement and control system;data processing
