IEEE/ASME Transactions on Mechatronics, 2020
In this article, a new two-dimensional piezoelectric actuator driven vibration stage is proposed and prototyped. A double parallel four-bar linkage structure with double-layer flexible hinges is designed to guide the motion and reduce the displacement coupling effect between the two directions.

Shunted magnetostrictive devices in vibration control
Smart Materials and Structures, 2020Abstract Structural vibrations in rotating machinery may lead to imprecise motion control, excessive noise, or even structural damage. Magnetostrictive materials can dissipate unwanted vibrations via hysteresis, eddy currents, and joule heating while exhibiting an electrically-tunable elastic modulus.

Active Vibration Control and Isolation for Micromachined Devices
Journal of Mechanical Design, 2008Some harsh environments contain high frequency, high amplitude mechanical vibrations. Unfortunately some very useful components, such as micro-electro-mechanical systems (MEMS) gyroscopes, can be very sensitive to these high frequency mechanical vibrations.

Controlling Floor Vibration with Active and Passive Devices
The Shock and Vibration Digest, 2003This paper reviews research, conducted by the authors over the last decade, pertaining to the control of ex- cessive floor vibration using active and passive devices. The active device studied uses a proof-mass actuator to deliver the control force to the floor system. Effectiveness and stabil- ity characteristics for a single-input/single-output (SISO)

DESIGN AND PERFORMANCE OF A PASSIVE VIBRATION CONTROL DEVICE FOR HAWT
Proceedings of the 8th International Conference on Computational Methods in Structural Dynamics and Earthquake Engineering (COMPDYN 2015), 2023This study proposes an innovative technique for reducing wind-induced stress at the base of a horizontal axis wind turbine (HAWT) and its foundation. The technique involves the use of a relaxed base constraint composed of rotational springs and friction devices in parallel, which dissipate energy to reduce bending moment demand while limiting ...
