Study on contact property simulation of random rough surface

Based on the idea of reverse engineering, random numerical rough surface with roughness and waviness was generated with Matlab. The data transfer module was programmed. The rough surface was reconstructed in Pro/E. The solid was transferred to ANSYS and computed with substructure method. Thus, the process was realized from random rough surface generation with computer to FEA between two rough surfaces. The stress distribution of the rough surface was obtained. The basis is supported for the surface design and mechanical failure trace analysis with the method.
