Abstract

Abstract

Two stochastic models on simple random system with friction were developed.One of them was a discrete model by a two-dimensional mean map applied to describe random stick-slip motion.The numerical examples show that external noise can reduce the complexity of the system behavior.Secondly,a probability model described was established with coexistence of stick-slip and slip motions.The numerical results point out that this model possesses pure stochastic behavior.
- stochastic frictional system,
- stick-slip motion,
- stochastic chaos
