Abstract：The friction coefficient has an important influence on the formation of friction-induced self-excited vibrations.However, in the experimental process, it is difficult to make an accurate control on the friction coefficient between two sliding surfaces.A finite element model of a metal reciprocating sliding system was established.The friction-induced vibrations during a reciprocating sliding process were simulated using the transient dynamic analysis and complex eigenvalue analysis.In the simulation, the friction coefficient between two friction contact surfaces was controlled precisely.The dynamic transient analysis results indicate that the friction coefficient has a significant effect on the continuation and magnitude of the friction-induced self-excited vibrations and it has a little influence on the frequency of friction-induced self-excited vibrations.The complex eigenvalue analysis results show that with the increase of the friction coefficient, the vibration mode of the metal reciprocating sliding system changes significantly.
