A torsional vibration damper having limit stops to limit the compression of the springs and to avoid overstraining of the springs. Spring retainers which seat on the driving and driven members have protrusions and recesses to minimize relative rubbing motion and wear and provide improved alignment of the spring seats in the assembly with the springs ...

Impact of Inertia Control of DFIG-Based WT on Torsional Vibration in Drivetrain
IEEE Transactions on Sustainable Energy, 2020As wind power reaches a high penetration in power systems, inertia control is required in grid codes to improve the system frequency dynamics. This supplemental control will couple the mechanical system of wind turbines (WTs) with the electrical system ...

Analysis of stick-slip reduction for a new torsional vibration tool based on PID control
Proceedings of the Institution of Mechanical Engineers, Part K: Journal of Multi-body Dynamics, 2020The phenomenon of stick-slip vibration is widespread in the exploration of deep and ultra-deep wells. It causes the reduction of the mechanical drilling rate and wastes the driving energy.
