Full and half-wavelength ultrasonic percussive drills [PDF]
, 2018 Ultrasonic-percussive drills are a leading technology for small rock drilling applications where power and weight-on-bit are at a premium. The concept uses ultrasonic vibrations to excite an oscillatory motion in a free-mass, which then delivers ...

On the formation of limit cycle of the friction-induced stick-slip vibration in oilwell drillstring
Petroleum, 2015 In this paper, the stick-slip vibration in oilwell drillstring is studied. The drilling system is modelled as a lumped-parameter torsional pendulum and the interaction between the drill bit and the rock is treated as Coulomb friction.
