Abstract
The aim of this work is to analyze the axial nonlinear dynamics of a vibro-impact system used as a drilling tool. A parametric analysis investigates the effect that some design parameters have on the dynamic behavior of the system. Furthermore, a measure is proposed to evaluate the efficiency of the process, and used for design modifications of the current vibro-impact system. The results reveal the possibility of 85 % increase in the impact force transfer when compared with the original design.
