Design analysis of a magnetorheological damper

SPIE Proceedings, 2005
The design method of a cylindrical magnetorheological (MR) damper is established. The viscosity model is used to describe the viscous characteristics of the MR fluids subject to an applied magnetic field. The equation for the damping force is derived to provide the theoretical foundation for the design of the damper.

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.

Investigations of a Magnetorheological Fluid Damper

IEEE Transactions on Magnetics, 2004
This paper presents the results of a study of a magnetorheological fluid (MRF) damper. The principle could be used for such applications as seismic protectors for civil structure (where the dimensions are chosen to handle the greatest forces) or shock absorbers for the automotive industry (where the dimensions are chosen to accommodate heating effects).

Analysis and Design of Magnetorheological Damper

Advanced Materials Research, 2010
Magnetorheological (MR) dampers are the semi-active control devices that use MR fluids to produce controllable dampers. In this paper, the design method of the cylindrical MR damper is established. Bingham model is used to describe the constitutive behavior of MR fluids subject to an applied magnetic field. The equation for the damping force is derived

Magnetorheological dampers in shear mode

Smart Materials and Structures, 2007
In this study, three types of shear mode damper using magnetorheological (MR) fluids are theoretically analyzed: linear, rotary drum, and rotary disk dampers. The damping performance of these shear mode MR dampers is characterized in terms of the damping coefficient, which is the ratio of the equivalent viscous damping at field-on status to the damping

Heating effects on magnetorheological dampers

2010
Over the past decades, scientists and engineers have tried to develop and improve various devices and control systems in order to mitigate and prevent civil structures against external dynamic forces such as strong wind and earthquakes. Indeed, damping devices absorb and dissipate the energy input during an earthquake, for instance and thus make ...
