Abstract In order to deeply study effects of propulsion force and exciting frequency on characteristics of a rock crushing system with down-the-hole (DTH) hammer in rock fragmentation process, a dynamic model considering local contact and complete contact states between DTH hammer and rock was established based on spring, damper, slider and other components. Dynamic equations of the system under different states were established, respectively. The continuous dimensionless dynamic differential equations of the rock crushing system were established based on the step function. Runge-Kutta method was used to solve the equations, and obtain displacement diagram, velocity one, phase plane one and Poincaré sectional view of the DTH drill bit under different conditions. The results showed that the motion state of the rock crushing system changes with variation of propulsion, when the system is in the period-1 state, it is relatively stable and its rock crushing efficiency is best; with increase in exciting force frequency, the stable range of the system expands, but the rock crushing efficiency drops; the study results of dynamic characteristics of the rock crushing system provide a theoretical basis for determining parameters of DTH hammer under actual working conditions.

Key words： DTH hammer dynamic model rock crushing efficiency periodic motion chaotic motion
