| 摘 要： | 针对不同固体材料在不同条件下的摩擦磨损实验要求,设计了一种基于ARM微处理器的气动变载荷摩擦磨损试验机测控系统。采用气动加载方式,加载形式包括正弦波、方波、锯齿波、三角波、随机波等。气动加载采用Fuzzy-PID闭环控制,提高了动态加载性能。可通过测量实验中的摩擦力、摩擦系数、磨损量、温度、振动等参数来研究变载荷对材料摩擦磨损性能的影响。最后对A3钢材料的摩擦磨损性能进行试验,证明该试验机性能稳定,测控系统准确可靠。 |

| 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. |
