Abstract

Abstract : In order to resist the abrasion of sand and gravel, shellfish such as arca subcrenala lischke and arca inflata reeve have evolved non-smooth surface morphology with high wear resistance. In this paper, four biomimetic structures of prismatic, conical, ball crown and stripd were designed to study the abrasive wear behavior of different biomimetic structures. Built on the Discrete Element Method (DEM), the DEM model and its abrasive wear calculation model are established. By analyzing the changes of the contact bond field of the abrasive wear system, the non-uniform evolution process and wear law of the abrasive wear process of the four bionic structures are obtained. The research in this paper provides a new research method and means for the numerical simulation of wear behavior of biomimetic structures and the optimal design of biomimetic structures based on the surface morphology of biological non-smooth wear-resistant bodies.
