Study on the Development of Passive MR Damper with Displacement-Dependent Damping Characteristics

open access: yesJournal of Fluid Science and Technology, 2010
In this paper, we propose a new concept of a magneto-rheological (MR) fluid damper, which is a passive MR fluid damper. The passive MR damper has no electrical devices, such as a sensor, power supply and controller, and hence, it has an advantage in ...

Vibration control of spar‐type floating offshore wind turbine towers using a tuned mass‐damper‐inerter

open access: yesStructural Control & Health Monitoring, 2019
This paper investigates the use of a passive tuned mass‐damper‐inerter (TMDI) for vibration control of spar‐type floating offshore wind turbine towers. The TMDI is a relatively new concept as a passive vibration control device. The configuration consists
