The self-synchronized phenomena generated in a coupled self-excited oscillators acting on Coulomb's friction are analytically investigated. This system consists of two nonlinear self-excited oscillators coupled in series. In this system, the stick-slip vibration often occurs resulting from the friction. The shooting method is improved in order to analyze the discontinuous systems. As results, there are unstable regions based on saddle-node or period-doubling bifurcation alternately exist on the branch of Model, which the blocks vibrate nearly in-phase. In this relation, we analytically show that such unstable regions are caused by internal resonance by dealing with variational equation of the model which the same oscillators are coupled.
