Abstract

A dynamic model of percussive drilling assuming a dry friction mechanism to explain the experimentally observed drop in penetration rate is presented. The inherent nonlinearity of the discontinuous impact process is modelled as a frictional pair, and this can generate the pattern of the impact forces close to reality. Despite quite radical simplifying assumptions, the model is able do describe the fall of material removal rate for a higher static loading with a good agreement to experimental investigations.
