Note générale : tribology Langues : Anglais (eng) Mots-clés : joint  surface;  elliptical  asperities;  unit  area;  contact  stiffness;  macro/micro  parameter Index. décimale : 621.5 Energie pneumatique. Machinerie et outils. Réfrigération Résumé : Based on the Greenwood and Williamson theory, an assumption about the contact-area size of asperities on rough surfaces is proposed under the premise that the height of these asperities on rough surfaces is a Gaussian distribution. A formula has been derived to measure the number of asperities on 2D surfaces. The contact stiffness on a unit length of a 1D outline and that on a unit area of 2D surfaces are presented based on a formula for determining the number of asperities. The relationship between macro parameters, such as contact stiffness and micro parameters on the joint surface, is established.
