Abstract

The paper presents a physical and mathematical model of mass-spring system with friction that enables to clarify and to analyse the stick-slip motion. The essential novelty in this model is inclusion of tangent contact flexibility and damping, also of optional characteristics on static, kinematic and dynamic friction. The characteristics take into consideration the increase of the static friction force (coefficient) with increasing time of repose (stick mode duration), also the relationship of the motional friction force from the sliding velocity and acceleration for the slip mode. The model has been developed basing upon the results obtained from autors experimental study. Presented are computer simulation program and examples. T
