Abstract
Friction wear testing machine is generally used in researches of various friction wear mechanisms, explorations of influences factors, and property evaluations of friction pair materials. Measurement accuracy and automation level of the friction wear testing machine directly influence the precision of data acquisition and analysis processing, as well as the intuition of data displaying. Based on virtual instrument LabVIEW, a data acquisition system of friction wear testing machine was developed. Hardware of this data acquisition system mainly consists of sensors utilized as acquiring information on rotate speed, normal pressure, friction force and temperature, as well as signal conditioning module and data acquisition card. Utilizing the LabVIEW, data processing and interface displaying software was programmed. Debugging results confirmed that the developed system can accurately acquire the demand information when operating the friction wear testing machine, also intuitively display these obtained information in real-time. Therefore, the developed data acquisition system satisfies the demand of precisely acquiring information related to friction wear testing of experimental materials.
