Verification of a simplified rough surface contact analysis method using Herzian contact and interface betweeen asperities

Abstract

In industry, the demand for knowledge about contact conditions is quite significant. There are conventional methods called statistical methods to analyze contact conditions. Another relativery new method is direct simulation. However, there are still problems to be solved in terms of analysis accuracy and calculation cost. Therefore, in this study, we proposed simplified rough surface contact analysis using Herzian contact and interface betweeen asperities, and verified the validity of this method. As a result, numerical experimental evaluations confirmed that in a small number of asperities, the change trend is relatively close to that of Hertzian elastic contact theory.
