Analysis of the effects of torsional impact tools on drill string stick–slip vibration

open access: yesEnergy Exploration & Exploitation
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.

Active Control of Drive Chain Torsional Vibration for DFIG-Based Wind Turbine

open access: yesEnergies, 2019
Due to the fast electric control of the doubly-fed induction generator (DFIG) when experiencing power grid disturbance or turbulent wind, the flexible drive chain of the wind turbine (WT) generates long-term torsional vibration, which shortens the ...
