Shock isolation systems using magnetorheological dampers

SPIE Proceedings, 2004
This study addresses the feasibility and applicability of a semiactive magnetorheological (MR) shock isolation system to replace a conventional passive shock isolation system for commercial-off-the-shelf (COTS) equipment. To this end, an analysis of a shock isolation system with an MR damper was theoretically developed.

Design and analysis of a magnetorheological damper for train suspension

SPIE Proceedings, 2004
This article aims at designing a magnetorheological (MR) fluid damper that is suitable for a semi-active train suspension system in order to improve its ride quality. A double-ended MR damper is designed, fabricated, and tested. Simulation is carried out by integrating the MR damper model in the secondary suspension of a full-scale railway vehicle ...

Experimental analysis of magnetorheological dampers for structural control

Smart Materials and Structures, 2003
The possibility of reducing structural response under strong external excitations such as earthquakes and wind storms via control systems is attracting the interest of a large number of researchers. In the field of civil structures, control systems based on semi-active devices seem to be close to feasible implementation.

Fuzzy modeling of a magnetorheological damper using ANFIS

Ninth IEEE International Conference on Fuzzy Systems. FUZZ- IEEE 2000 (Cat. No.00CH37063), 2002
The magnetorheological (MR) damper is a semi-active control device that has received much attention by the vibration control community. Of primary interest is its fast response to a variable control signal as well as its low power requirements. The highly nonlinear dynamic nature of this device, however, has proven to be a significant challenge for ...

Real time identification of structures with magnetorheological dampers

Proceedings of the 41st IEEE Conference on Decision and Control, 2002., 2003
A real-time identification algorithm for structures with magnetorheological dampers as energy dissipation devices is described. These dampers are modeled by the use of a modified LuGre dynamic friction model, whose internal state is calculated with a nonlinear observer. The convergence analysis for the identification-observer scheme is presented.

Preparation of magnetorheological fluid and its application in a magnetorheological damper

Physics of Fluids
To enhance the mechanical properties of built-in valve-type magnetorheological dampers, a new magnetorheological fluid (abbreviated as HCMN-MRF) prepared using hydroxylated carbon nanotubes (HCNT)-coated micrometer-sized carbonyl iron particles (CIPs) mixed with nano-sized iron particles (NIPs) was investigated in this study.

Design and modeling of magnetorheological dampers

2014
Magnetorheological (MR) damper is one type of semi-active devices that shows a great potential for vibration suppression and hazard mitigation of civil structures. One special advantage of the damper is that its damping characteristics can be adaptively and quickly altered by a varying magnetic field.
