PEEK摩擦信号分形维数与表面形貌相关性试验研究
Research on Correlation of Friction Signals and Surface Topography of PEEK
摘要
Abstract
In order to investigate the correlation of friction force and coefficient signals of PEEK/QT400 and initial surface topography of PEEK,friction and wear tests of PEEK/QT400 were carried out on an UMT-3MT wear tester with same velocity and different loads.The fractal behaviors of initial surfaces topography and friction signals were studied with fractal theory and the fractal dimension of them were calculated using structure function measurement method.Results show that the initial surface of PEEK and friction signals both have obvious fractal characteristics,under the same velocity and same initial surface,the value of fractal dimension increases with the increases of contact load,and under the same velocity and different loads,friction signals of preliminary running-in stage and initial surfaces of PEEK are both positive correlations.关键词
