Mechanism and solutions of stick-slip vibration of near-horizontal directional drilling in underground coal mine

open access: yesMeikuang Anquan, 2022
Stick-slip vibration generally exists in the process of drilling and construction, and near-horizontal directional drilling in underground coal mines is no exception.

Dynamic analysis of coal stick-slip impact based on physical information neural network

open access: yesMeikuang Anquan, 2023
At present, physical information neural network has become a new paradigm for numerical calculation of engineering mechanics. It can solve partial differential equations by integrating the physical mechanism of neural network in the case of unlabeled ...

Effect of stick-slip on magneto-rheological elastomer with a magnetic field

open access: yesFriction, 2017
This study investigated the stick-slip characteristics of a magneto-rheological elastomer (MRE) against an aluminum plate. Herein, the MRE was manufactured, and a stick-slip tester was employed to evaluate the stick-slip performance of the MRE under ...

Multiscale Stick-Slip Dynamics of Adhesive Tape Peeling [PDF]

open access: yes, 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 ...

Discussion of Stick-Slip Dynamics of 2DOF Sliding Systems Based on Dynamic Vibration Absorbers Analysis

open access: yesLubricants, 2022
In this study, we discussed the occurrence condition stick-slip model based on a 2DOF system, in which a 1DOF system model commonly used in stick-slip analysis was attached on an elastic foundation.

Stick-slip fluctuations in granular drag [PDF]

open access: yesPhysical Review E, 2001
We study fluctuations in the drag force experienced by an object moving through a granular medium. The successive formation and collapse of jammed states give a stick-slip nature to the fluctuations which are periodic at small depths but become "stepped" at large depths, a transition which we interpret as a consequence of the long-range nature of the ...

Stick-slip vibration behaviors of BHA and its control method in highly-deviated wells

open access: yesAlexandria Engineering Journal, 2022
Stick-slip vibration is a common phenomenon met in oil gas drilling, especially in the complex trajectory wells such as highly-deviated wells, it will cause the earlier failure of BHA (bottom hole assembly) and lower drilling efficiency.

Role of friction-induced torque in stick-slip motion [PDF]

open access: yes, 2010
We present a minimal quasistatic 1D model describing the kinematics of the transition from static friction to stick-slip motion of a linear elastic block on a rigid plane.

Strong dynamical effects during stick-slip adhesive peeling [PDF]

open access: yes, 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 ...
