Heating of Magnetorheological Fluid Dampers

Journal of Intelligent Material Systems and Structures, 1999
This paper presents experimental and theoretical studies on heat generation and dissipation of fieldcontrollable, magneto-rheological (MR) fluid shock absorbers. Since MR fluid dampers are energy-dissipating devices, the issues of heat generation and dissipation are important.

Skyhook Isolation with Magnetorheological Damper

2006 6th World Congress on Intelligent Control and Automation, 2006
Magnetorheological (MR) damper is a kind of semi-active device. Its damping can be controlled by input electrical currents. In this paper, a modified bi-viscous and hysteretic model is proposed to describe the bi-viscous and hysteretic behaviors of MR damper. The model parameters have direct physical significance to the MR damper properties.

Analysis of magnetorheological fluid damper

Journal of Central South University of Technology, 2007
Magnetorheological fluids(MRF) are smart materials consisting of silicon oil and very small soft-magnetic particles. In a magnetic field, the viscosity and the flow behaviour of the fluid are considerably changed. MRF damper is a device to give damping by the shear stress of MR fluids.

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 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.

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

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 ...
