Abstract :
In this paper we introduce a bristle model for stick-slip friction. The friction force of the bristle model is generated by frictionless contact between a body and an infinite row of bristles. Each bristle is attached to the ground through a torsional spring so that, as the body moves, the bristles pivot and counteract its motion. We show that the bristle model exhibits stick-slip motion similar to that of the LuGre model. We then form a hybrid model by combining the LuGre and bristle models.
