Abstract

We developed a theoretical model and an experimental procedure to investigate the rolling friction coefficient in a micro rolling tribosystem. The procedure we suggest is based on the integration of the free oscillation equations of a microball on a spherical surface. The rolling friction coefficient was evaluated on the basis of the number and amplitude of the experimentally determined ball oscillations. The influence of condensing atmospheric water on the rolling friction coefficient at the level of rolling micro tribosystems was also determined.
