| Abstract: | The contact problem of joint interface plays a significant role to the dynamic characteristic of CNC machine tools,it＇s the major factor to determine the total stiffness and damping of machine tools system. The paper summarized the three models commonly used for researching the stiffness of mechanic joint interface in machine tools,namely Hertz contact model,G-W statistical contact model and fractal contact model. Meanwhile,based on W-M function,the 3-D topography of rough surface was simulated,and the meanings of fractal parameters G and D was analyzed. |
