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.

各向异性界面法向接触刚度和阻尼的建模

摘要-

当两个各向异性粗糙表面接触时，界面表现为接触各向异性或接触各向同性，这与微观尺度上的凹凸接触方位角密切相关。界面接触各向异性/各向同性会影响机械接头的法向接触刚度和阻尼。提出了两个各向异性粗糙表面之间的法向接触刚度和阻尼模型，其中包括粗糙肩肩接触和相邻粗糙相互作用的影响。并通过一系列仿真实验揭示了接触匹配度和接触各向异性对法向接触刚度和接触阻尼的影响规律。从而，
