Semi-active control of crankshaft skyhook based on magnetorheological torsional damper
Frontiers in Materials, 2022 The purpose of this study was to solve the problem that the damping of rubber or silicone oil torsional dampers used in crankshafts is not adjustable and cannot effectively control torsional vibration at different resonant frequencies.

No Effect of Steady Rotation on Solid $^4$He in a Torsional Oscillator [PDF]
, 2015 We have measured the response of a torsional oscillator containing polycrystalline hcp solid $^{4}$He to applied steady rotation in an attempt to verify the observations of several other groups that were initially interpreted as evidence for macroscopic ...

Analysis of the effects of torsional impact tools on drill string stick–slip vibration
Energy Exploration & ExploitationTorsional 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
Energies, 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 ...
