The Research Of Testing And Controlling System Of Friction Material Capability Testing Machine

The advanced testing and controlling technology of friction testing machine has the vital significance regarding the friction material capability research thorough development. With the great development of computer technique, automatization testing technique is being mature little by little, so it is a very important content of friction material capability testing technique to use automatization testing technique to friction testing machine. This article develops the testing and controlling system of friction material capability testing machine, are precisely these technical and friction testing machine organic synthesis product.This thesis discusses the design and implementation of the testing and controlling system of friction material capability testing machine. The main content of this thesis includes a detailed scheme of the system is put forward and the whole structure is designed based on analyzing the measure principle of test signal and realization objective of the system, the selection of hardware, the design of signal processing and resisting disturbance. And then the software design is analyzed and the pivotal technology of software is discussed. Finally the design of the software function modular and the software interface is accomplished by use of Visual Basic 6.0.The testing and controlling system developed in this task implement experiment datum's real-time collection about pressure, moment, temperature, rotate speed and friction coefficient, analysis processing, the data curve fitting, the memory, the record printing, and control output. The system has simple operation, reliable data and good reappearance. Through the experimental proofs which carries in this friction testing machine, this testing and controlling system has steady performance, friendly interface and well adaptability and reliability. It has important meaning to raising the standard of testing and controlling of friction testing machine.Finally, this thesis provides a summary of the research work and made some recommendations for the future research.
