| Abstract: | Dynamics of a two-degree of freedom vibration system which is under harmonic force and contains the non-smooth mechanical factors clearance and friction is studied in this paper.The sticking and sliding periodic vibration and the bifurcation characteristics presented with increasing or decreasing the exciting frequency of this piecewise smooth vibration system is revealed by means of numerical simulation.The influence of the friction coefficient on the periodic impact vibration,bifurcation and sliding-sticking phase of the system is analyzed. |
