Abstract

Traditional rough surface contact models either neglect the interaction between asperities, resulting in inaccurate analysis results, or adopt exhaustive method because of considering interaction, resulting in a huge amount of calculation. In order to establish an efficient and accurate contact model for rough surfaces, the deformation distribution of asperities considering interaction is analyzed by exhaustive method, based on Green function. The results show that the deformation of the asperity still obeys the normal distribution approximately. Therefore, a fitting function is established to describe the distribution of asperities under micro-interaction through data analysis. Then, a new contact model for rough surfaces considering of microscopic interaction is established. Compared with the exhaustive method, the correctness of the model is verified, and the efficient and accurate analysis of rough surface is realized.
