Canards in stiction: on solutions of a friction oscillator by regularization [PDF]
, 2017 We study the solutions of a friction oscillator subject to stiction. This discontinuous model is non-Filippov, and the concept of Filippov solution cannot be used. Furthermore some Carath\'eodory solutions are unphysical.

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 ...

Measurement and Analysis of Downhole Drill String Vibration Signal
Applied Sciences, 2021 Downhole drill string vibration data can provide an effective reference for research drill string vibration during drilling. In this paper, the research group used a storage-type downhole vibration measurement equipment equipped with an orthogonal, three-

Acoustically-induced slip in sheared granular layers: application to dynamic earthquake triggering [PDF]
, 2015 A fundamental mystery in earthquake physics is ``how can an earthquake be triggered by distant seismic sources?'' Here, we use discrete element method simulations of a granular layer, during stick-slip, that is subject to transient vibrational excitation

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 ...

Multiscale Stick-Slip Dynamics of Adhesive Tape Peeling [PDF]
, 2015 Using a high-speed camera, we follow the propagation of the detachment front during the peeling of an adhesive tape from a flat surface. In a given range of peeling velocity, this front displays a multiscale unstable dynamics, entangling two well ...
