| Abstract: | The micro profiles of rough surfaces influence heavily on the contact characteristics of machine joint surfaces. Although some researches on the normal contact stiffness of machine joint surfaces have been made, they were all based on statistical analysis of rough surfaces. So their results are all dependent on the scale. In order to solve this problem, the fractal model for normal contact stiffness of machine joint surfaces is built up under some given hypotheses based on Hertz contact theory between a sphere and a plane and the contact fractal theory between rough surfaces, which is independent upon the scale. The simulation results of the model are identical with that of the related experiment. |
