Abstract
The accurate estimation of real contact area plays an important role in predicting the mechanical contact situation and associated electrical contact resistance for engineering rough surfaces. In this work, an improved peak identification method is proposed to reconstruct the rough surface morphologies numerically. A universal calculation process of real contact area and load force under the progressive indentation depth for rough surfaces is developed. Furthermore, a three-dimensional finite element model for analyzing the mechanical contact problem is built and the electromechanical coupling simulation results are compared with that obtained by our novel calculation method. The proposed solution is beneficial for accurate calculation of contact area, which is featured by high aspect ratio in the case of micro-contact. The relationship between electrical contact resistance and load force is also captured in the initial contact process.
