| Abstract |
When two anisotropic rough surfaces contact, the interface is shown as the contact anisotropy or contact isotropy, which closely relates to the asperity contact azimuthal angles on the microscopic scale. The interfacial contact anisotropy/isotropy will influence the normal contact stiffness and damping of mechanical joints. A normal contact stiffness and damping model between two anisotropic rough surfaces is proposed, which includes the effects of the asperity shoulder-to-shoulder contact and adjacent asperity interaction. And the influence laws of the contacting match degree and the contact anisotropy on the normal contact stiffness and contact damping are revealed by a series of simulation experiments. Thereby, the normal contact stiffness and damping can be controlled by adjusting the surface topographic features and the contacting orientation between mechanical parts. |
