The aim of this work is to analyze the axial nonlinear dynamics of a drilling tool. The force at four impact surfaces are analyzed. Then, a parametric analysis is performed to investigate the effect that some parameters have on the dynamic behavior of the axial nonlinear dynamics of a drilling tool. 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 and 125% increase in the mud flow operating range, when compared with the original design.
