Study of the Dynamic Behaviour of the Friction Coeficient of Electrographite Brushes

The research reported in this paper represent the continuation of the revious work on the problem of the friction coefficient of brushes under a pulsating current. In the first part and experimental investigation has been conducted to determine the behaviour of the friction coefficient during transient conditions. Using the results of the experimental investigations, a dynamic model of the friction process has been developed that helps to predict behaviour of the friction coefficient of brushes under real working conditions. The process has been simulated using a bond graph based modelling approach.
