Friction Performance of the Bionic Surfaces with Convex Domes

Abstract:

The bionic surfaces with convex domes were designed based on the bionic tribology. Using the self-made test-bed for measuring the plane friction coefficient, the friction coefficients between the samples and the belt were measured. The belt’s type used for tests is NN-100 and its number of plies is three, as a fixed contact surface. The samples consisted of the convex dome with spherical crown, convex cylinder and smooth rubber surface as a comparative sample as well. The influences of the press, temperature and loading time on the friction performance of the bionic surface with convex dome were analyzed by the friction coefficient in the different conditions. Compared with the measuring result of the smooth rubber surface, the increasing-friction effect of the bionic surface is analyzed and the influences on the bionic surface from the factors mentioned above are examined if they are the same with those on the smooth surface. According to the test results, the influences on the friction performance from the shape, dimension and hardness of the convex dome are discussed and the increasing-friction mechanism is analyzed.
