| Abstract |
In mechanical systems, the machining surfaces of various components, especially those
subjected to precision machining such as the roller and track surfaces in feed systems, often exhibit
non-Gaussian roughness characteristics, which significantly differ from the Gaussian surface model
widely adopted in traditional contact models. In order to thoroughly investigate the influence mechanism of characteristic parameters of non-Gaussian rough surfaces on the contact performance of
mechanical interfaces, this study specifically constructs a contact model for non-Gaussian rough surfaces. This model elaborately elucidates the complex effects of skewness and kurtosis, two key parameters, on contact force, actual contact area, and contact stiffness. Thus, it deepens the understanding
of contact characteristics of non-Gaussian rough surfaces and provides a theoretical basis for the analysis and optimization of the contact performance between rollers and tracks in feed systems. |
