Analysis on the Friction Performance of the Bionic Surface with the Convex Domes for Increasing Friction

Abstract

The surface micro textures on the feet of the animals such as flies, geckos and tree frogs have been studied. According to the research result and the science of the bionic tribology, the bionic surfaces with the convex domes which possess the certain structural features are obtained. They can increase the friction coefficient. The increasing friction mechanism of the bionic surface with the convex domes is analyzed using the methods of theory analysis, simulation and experimental verification. The friction force between the bionic surface with the convex domes and the belt consists of the sliding friction force and the additional resistance resulting from the inlaying meshing effect. The contact transformation of the bionic surface with cylindrical convex domes and the belt is simulated by the software ANSYS. The increasing friction effect of the bionic surface with the cylindrical convex domes is verified by the experiments.
