Abstract :
The variation of friction force between upper test specimen and nether test specimen is very complicated on the reciprocating wear tester. There are many factors exerting influence on it. Based on the bench test, a system is developed for measuring the variation of the friction force between upper and nether test-piece. The acquisition of anolog signals is done by pressure transducer. The digital signals can be get after A-D conversion basing on MCUAT89S52 and ADC0832. The analysis and calculation of the obtained data can also be achieved with PC in the system and VB is used to make the interface of PC. In order to reflect the running status much more directly and clearly, the real-time curve is also made to provide the foundation for the further investigation.
