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

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.

Experimental Test Bench for Magnetorheological Damper

AIP Conference Proceedings, 2009
In the paper it is presented a non conventional method to characterize the work of a semi‐active damper with magnetorheological fluid, using a modified Charpy pendulum. In order to obtain different impact velocities, the pendulum can be launched at different angles; in this way, it is modified the kinetic energy before the impact, which can be ...

Skyhook damping with linearized magnetorheological dampers

SPIE Proceedings, 2004
In recent years, much research has focused on the development of effective control strategies for smart fluid dampers. In particular, skyhook control principles are frequently shown to demonstrate significant performance improvements over conventional passive systems.

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.

Modeling of magnetorheological damper using ANFIS

2017 29th Chinese Control And Decision Conference (CCDC), 2017
Magnetorheological (MR) damper is a semi-active actuator, it responds to a variable control signal very fast in the meanwhile it requires a very low power. Due to the highly nonlinear dynamic nature, it is difficult to characterize the behavior of this actuator.

Experimental Investigation on Magnetorheological Damper’s Characterization

Advanced Materials Research, 2015
Magnetorheological (MR) damper is one of the most advanced application of semi active devices. Its use is increasing day by day due to its huge advantages and wide range of application. The force delivered by MR damper can be varied by changing the viscosity of its internal MR fluids.

Adaptive control of magnetorheological fluid damper

2017 52nd International Universities Power Engineering Conference (UPEC), 2017
This paper discusses an adaptive algorithm to control a magnetorheological fluid vibration isolator operating under varying frequency of the vibration source. The algorithm provides automatic tuning of the isolator properties by controlling the viscosity of magnetorheological fluid in the throttle channels.

Nonlinear Structural Control Using Magnetorheological Damper

2013
This chapter provides an introduction to semi active control of base isolated buildings using magnetorheological (MR) dampers. Recently developed nonlinear control algorithms are discussed. First a fuzzy logic control (FLC) is designed to decide how much voltage is required to be supplied to the MR damper for a desired structural response.
