Frequency and current effects in a MR damper

International Journal of Vehicle Autonomous Systems, 2009
This paper deals with Magneto-Rheological (MR) damper modelling and identification. The effect of the frequency and current is analysed through a database of four experimental datasets with different displacement and current. The benchmarking of modified models of a literature model approach is done.

Variable Transmission Compliance With an MR Damper

Aerospace, 2004
This paper presents a novel transmission design that consists of a parallel combination of an MR damper and a compliant element together acting in series with an actuator. By adjusting the magnetic field to vary the amount of damping, the transmission can be switched between compliant and effectively rigid modes.

Hierarchical fuzzy identification of MR damper

SPIE Proceedings, 2009
Magneto-rheological (MR) dampers, recently, have found many successful applications in civil engineering and numerous area of mechanical engineering. When an MR damper is to be used for vibration suppression, an inevitable problem is to determine the input voltage so as to gain the desired restoring force determined from the control law. This is the

Study of the response time of MR dampers

SPIE Proceedings, 2009
Response time is an important parameter which determines the applied fields and practical vibration reduction effects of magnetorheological (MR) dampers. However, up to now, only a few papers discuss the test and analysis of response times. In this paper, the response time of a large-scale MR damper at different velocities and currents was firstly ...

Fault Detection for an Automotive MR Damper

IFAC Proceedings Volumes, 2012
Abstract Driving with faulty dampers can throw the car off balance sending it out of control. Common faults of Magneto Rheological (MR) dampers are loss of oil volume because oil leakage. A fault detection system for monitoring the damper condition is proposed.

Mathematical Modelling and Design and of MR Dampers

Volume 2, 2004
Most magnetorheological (MR) fluid devices are fixed-pole valve mode devices where the fluid flows through a magnetically active valve. Controlling the strength of the magnetic field inside the valve allows the rheological properties of the MR fluid to be varied.

Precise Stiffness Control with MR Dampers

2013
Mag can be used not only as controllable damping devices but also to emulate a controllable positive or negative stiffness in combination with the dissipative force. However, the dissipative nature of MR dampers constrains the stiffness control. This work formulates the problem of combined stiffness and damping control with MR dampers if the damper is ...
