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

The impact of multidirectional excitation on the stick–slip vibration characteristics of a drill string [PDF]
Stick–slip vibration is a common phenomenon in ultra-deep drilling that significantly impacts the failure of both drill bits and drill tools. The most direct and efficacious approach to alleviating the stick–slip vibration of the drill string in the ...

On the stick-slip vibration in the suspension of a freight wagon [PDF]
Damping based on the dry friction is frequently in suspensions of the freight wagons. The paper presents some aspects of vertical vibration of freight wagons. It uses a simple model considering that the vehicle was reduced to a mass suspended on a wheel,

The inhibition mechanism of ultrasonic vibration on stick-slip phenomenon of sliding friction pair [PDF]
Frictional vibration often occurs during sliding, commonly referred to as the stick-slip phenomenon. It is more likely to occur in the range of the Stribeck curve, where friction and velocity have negative gradient characteristics.

Suppression of Drill-String Stick-Slip Vibration [PDF]
We investigate experimentally and numerically suppression of drill-string torsional vibration while drilling by using a sliding mode control. The experiments are conducted on the novel experimental drilling rig developed at the University of Aberdeen [1]

Analysis of the effects of torsional impact tools on drill string stick–slip vibration
Torsional impactor is widely used in deep and ultra-deep wells because it can suppress stick–slip vibration and increase ROP. As the direct factor affecting torsional impactor effect, it's working parameters study is still not sufficient.
