One of the effect of the presence of the friction forces in mechanical systems is the stick-slip phenomenon. A numerical-experimental study of the vibration response of a single degree of freedom system, with Coulomb friction damping non¬linearity, is described. Particular emphasis is placed upon the numerical description of the friction force. The mass behaviour in the range frequency in which two to ten stops per cycle occur are investigated and discussed. The comparision of the experimental results to those obtained from the simulations shows a good agreement.

Abstract
One of the effect of the presence of the friction forces in mechanical systems is the stick-slip phenomenon. A numerical-experimental study of the vibration response of a single degree of freedom system, with Coulomb friction damping non¬linearity, is described. Particular emphasis is placed upon the numerical description of the friction force. The mass behaviour in the range frequency in which two to ten stops per cycle occur are investigated and discussed. The comparision of the experimental results to those obtained from the simulations shows a good agreement.
