Stick-slip fluctuations in granular drag [PDF]
Physical 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 Characteristics Study of the Drill String Based on PID Controller
Energies, 2023 In order to address the issue of drill string stick–slip vibration, which leads to drill bit wear and reduces the drilling velocity, we conducted a study on the characteristics of stick–slip vibration using a proportional-integral-derivative (PID ...

Stick-slip behaviour in sliding rubber contacs [PDF]
, 2023 The stick-slip phenomena play an important role in sliding contacts. The presence of that dynamic phenomena indicates that a sliding system can be regarded as a dynamic system consisting of masses, dampers and springs.

Hydraulic Conditions for Stick‐Slip Tremor Beneath an Alpine Glacier
Geophysical Research Letters, 2022 Accumulating evidence suggests that glacier basal motion can produce seismogenic stick‐slip events caused by frictional resistance at the ice‐bed interface.

From transmission error measurement to Pulley-Belt slip determination in serpentine belt drives : influence of tensioner and belt characteristics [PDF]
, 2009 Serpentine belt drives are often used in front end accessory drive of automotive engine. The accessories resistant torques are getting higher within new technological innovations as stater-alternator, and belt transmissions are always asked for higher ...

Contact dynamics from the atomic scale to nanostructured surfaces [PDF]
, 2007 The collective mechanical behavior of a multitude of small contacts affects the friction between sliding bodies on the macroscopic scale. The contacts are complicated systems involving many atoms, which are constantly deformed, ruptured and reformed.

Test on Stick-Slip Vibration of PDC Bit in Horizontal Wells
Shiyou jixie, 2023 Stick-slip vibration can lead to PDC bit damage and downhole instrument failure,while testing is a method commonly used to study the stick-slip vibration of drill string system in horizontal wells.In the paper,a micro PDC bit was designed to conduct rock

Modelling the tuned criticality in stick-slip friction during metal cutting [PDF]
, 2015 Cutting is a ubiquitous process in nature and man-made systems. Here we demonstrate that, based on morphological patterns observed in experiments, the friction behaviour of metal cutting exhibits a criticality with cutting speed as a tuned parameter. The
