Design of Automatic Measuring and Testing System for End-face Friction and Wear Tester

End-face friction and wear experiment can simulate and test the tribological performance of the friction couple in case of face contacting.An automatic measuring and testing system for end-face friction and wear experiment was designed.Firstly,an automatic measuring and testing system of friction force was worked out on the basis of the established mathematic model of friction force and friction coefficient.Then,the intelligent testing and control system of end-face tester was studied.The experimental results indicate that the end-face friction and wear tester with the automatic measuring and testing system has the functions of the real-time measuring and testing,and can process the signals of the following parameters,i.e.load,velocity,temperature,friction force and friction coefficient.The processed signals can be shown in the form of table or graphical curve.Therefore,the designed tester can be used to evaluate the tribological properties of the testing materials real-timely,impersonally and quantitatively.
