Automotive Magneto-Rheological Dampers:Modelling and Parameter Identification using contrast-based Fruit Fly Optimisation [PDF]

, 2018
The present study discusses the mechanical behaviour and modelling of a prototype automotive magneto-rheological (MR) damper, which presents different viscous damping coefficients in jounce and rebound. The force generated by the MR damper is measured at

A Magnetorheological Fluid Damper for Rotor Applications [PDF]

International Journal of Rotating Machinery, 2004
Even though we are still far from industrial applications, in the last decade there has been increasing attention directed toward the employment of electrorheological (ER) and magnetorheological (MR) fluids in active bearings and active squeeze film dampers in rotordynamics.

Control of transtibial prosthetic limb with magnetorheological fluid damper by using a fuzzy PID controller

Journal of Low Frequency Noise, Vibration and Active Control, 2018
The damping characteristic of a healthy limb changes throughout the gait cycle. However, for amputees who are wearing mechanically passive damping prosthesis, the lack of ability to change the damping values might expose them to injuries and health ...

Design of a frictionless magnetorheological damper with a high dynamic force range

Advances in Mechanical Engineering, 2019
This article discusses an increase in dynamic force range in a spring–damper unit achieved by elimination of sealings’ friction. This friction is a part of damping force that cannot be controlled; therefore, it is undesirable in magnetorheological ...
