Magneto-Rheological Fluid Technology

Resumo

Increasingly, Magneto-rheological (MR) fluid technology has been successfully employed in various applications across various fields. This technology has received significant attention due to its adaptability in the operation of semi-active control systems requiring small power sources. It can potentially deliver highly reliable mechanical operations, managed by a magnetic field as the external operating power. To summarize current magneto-rheological technology, MR fluid can be described as a controllable material that is included in the group of smart materials that have the unique ability to change yield stress. This property can be used in MR devices to generate and control force. The aim of this chapter is to review recent research into MR fluid technology by describing the important factors affecting MR devices design, such as MR fluid properties, operational modes, magnetic materials, and magnetic circuits.
