Damper with magnetorheological suspension

Journal of Magnetism and Magnetic Materials, 2002
The paper presents a closed hydraulic circuit damper, having a magnetorheological suspension as a fluid medium, and an external field coil. The magnetorheological suspension is made of iron micro-particles in silicon oil. The volume ratio of the particles (mean diameter of 2.15mm and standard deviation of 0.40mm) is 25%.

Integrated numerical model for examining the performance of magnetorheological plastomer dampers: magnetorheological plastomer dampers

2023
Magnetorheological plastomers (MRPs) are composed of a soft polymer matrix, carbonyl iron powder (CIP) and magnetic and nonmagnetic particles. They have the potential to bring significant benefits to multiple industries and become the future of MRP dampers. MRPs are applied in the fields of damping, sensing, and medical devices.

Self-Powered Magnetorheological Dampers

Aerospace, 2006
This paper addresses the feasibility and effectiveness of a self-powered magnetorheological (MR) damper operated by the energy harvested from vibration and shock environment. For doing so, an energy-harvesting device is theoretically constructed and added to an MR damper.

The characteristics of regenerative magnetorheological damper

2016 IEEE Advanced Information Management, Communicates, Electronic and Automation Control Conference (IMCEC), 2016
Aiming at the problem of large energy consumption of the magnetorheological semi-active suspension, a kind of integrated regenerative magnetorheological damper is proposed. The improved polynomial model of the magneto rheological damper and the electromagnetic induction regenerative model are established.

Phenomenological Model for Magnetorheological Dampers

Journal of Engineering Mechanics, 1997
Semiactive control devices have received significant attention in recent years because they offer the adaptability of active control devices without requiring the associated large power sources. Magnetorheological (MR) dampers are semiactive control devices that use MR fluids to produce controllable dampers.

On the structural parameters of magnetorheological damper

International Journal of Applied Electromagnetics and Mechanics, 2010
A novel magnetorheological (MR) damper is presented in this paper. The check valves of the MR damper are configurated in order that the flow direction of the MR fluid is one-way, and the stretch damping force is greater than the compression damping force.

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.

Electromagnetic Design of a Magnetorheological Damper

Journal of Intelligent Material Systems and Structures, 2008
This study presents an electromagnetic design methodology for the magnetorheological (MR) damper. To improve the performance of the MR damper, the magnetic field should be effectively supplied to the MR fluid. Therefore, it is important that the magnetic circuit composed with the MR fluid, the ferromagnetic yoke for forming the magnetic flux path, and ...

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.
