| Abstract: | In this paper,we investigate a low dimensional model of percussive drilling with vibro-impact to mimic the nonlinear dynamics of the bounded progression.Nonholonomity which arises in the stick-slip caused by the impact during drilling fails to be correctly identified via the classical techniques.A reduced model without non-holonomity is derived by the introduction of a new state variable, of which averaging technique is employed successfully to detect the periodic motions.Local bifurcations are presented di... |
