Study on Drill String Stick-slip Vibration Pattern Under Bit-Rock Interaction
Shiyou jixie, 2023 Stick-slip vibration leads to high-frequency shear stress on drill string and premature fatigue of drill string.Therefor,the torsional vibration model of drill string system considering bit-rock interaction was built by coupling the bit-rock interaction ...

Stick-Slip Motion and Phase Transition in a Block-Spring System
, 2002 We study numerically stick slip motions in a model of blocks and springs being pulled slowly. The sliding friction is assumed to change dynamically with a state variable.

Strong dynamical effects during stick-slip adhesive peeling [PDF]
, 2013 We consider the classical problem of the stick-slip dynamics observed when peeling a roller adhesive tape at a constant velocity. From fast imaging recordings, we extract the dependencies of the stick and slip phases durations with the imposed peeling ...

Study on suppressing of stick-slip using dynamic vibration absorber
Nihon Kikai Gakkai ronbunshu, 2019 This study discussed design criteria for suppressing stick-slip using dynamic vibration absorber. First, a simplified analytical model that can quantify the effect of the dynamic vibration absorber on the occurrence and nonoccurrence conditions of stick ...

Stick-slip instabilities in sheared granular flow: the role of friction and acoustic vibrations
, 2015 We propose a theory of shear flow in dense granular materials. A key ingredient of the theory is an effective temperature that determines how the material responds to external driving forces such as shear stresses and vibrations. We show that, within our

Study of the influences of rotary table speed on stick-slip vibration of the drilling system
Petroleum, 2015 Stick-slip vibration presents one of the major causes of drilling problems, such as premature tool failures, low drilling efficiency and poor wellbore quality.
