基于 ARM 微处理器的气动变载荷摩擦磨损试验机测控系统
Friction and Wear Testing Machine Based on ARM Microprocessor of Pneumatic Load Measurement and Control System
摘要
Abstract
For the material surface characteristic research needs of the space operation process,a new changing load on the friction and wear tester based on the ARM microprocessor is proposed. The computer human-computer interaction interface and lower computer ARM unit is used to develop a measurement and control system of pneumatic variable load friction and wear testing machine. The loading mode using pneumatic and load forms included sine wave,square wave,sawtooth wave,triangle wave and random wave. ,Fuzzy-PID is used in pneumatic loading closed loop control to improve the dynamic loading performance. The influence of variable load on the tribological properties of material can be researched through measuring friction force,friction coefficient,wear,friction temperature and vibration parameters in experiment. Finally,the experiment results of A3 steel tribological properties prove that the proposed tester has stable performance and the test system is accurate and reliable.关键词
