I have been debating and writing about magnetorheological fluids and dampers on a few articles already, it's high time that I give you some information as to how they can be or how they are used.
Following are just some of their most common uses:
Constructions
Almost all of the structures found in an area where seismic activity occurs frequently employ magnetorheological dampers as vibratory dampers.
The best type of damper for structures built in earthquake-prone places is the semi-active one. They require little amount of electricity to operate which is an important element to think about as power outage during earthquakes are typically common.
Instead of utilising the key power source of the building to support the semi-active damper, they will do with just a supplemental power generator.
Bridges
Long bridges are also susceptible to crumpling due to seismic vibrations or surprisingly heavy loads. According to research the utilization of magnetorheological viscous damper can reduce the damage caused by gust winds, quake and heavy traffic loads.
Cars
The vehicle industry is one of the industries that utilize magnetorheological fluids and dampers the most. However , because MR liquid and damping system is kind of dear, they are only used in top of the range and expensive automobiles. The MR dampers are added in the suspension of cars like the Chevrolet Corvette, Audi R8 and Humvee.
Farming
Magnetorheological dampers are used in tractor cabin suspensions. The idea is very similar to that of semi- active vehicle suspensions. The aim of the dampers in tractor suspensions is to reduce the cabin movement - pitching, rolling and vertical.
Army
The MR fluid-embedded armor or suit has the advantages of standard clothing simple to wear and light-weight. However , once the MR fluid in the suit is turned on by circuits with flowing current, the armor can toughen in merely a millisecond and right away become bullet resistant.
I know that I would not be well placed to cover in detail the numerous uses of both magnetorheological liquid and magnetorheological damper in only 1 article. As you can see what I have provided above is just short yet useful information on how MR fluid dampers are being utilized.
To add some more information, I have included the benefits of magnetorheological dampers below:
MR liquid dampers don't need a seal or a bearing, but instead employ existing inexpensive elements found in passive dampers.
In the resonance passage, the MR dampers can be energized to offer a high damping level to protect the associated or main machine
The mandatory power to manipulate MR liquid dampers is comparatively low. The power requirement for effective resonance control is just around 10 W.
Just like every other damping system, magnetorheological fluid damping has its limitation. Outlined below are 2 of them:
High installation cost (which can often be counterbalanced by the added potency in performance it contribute)
Most MR dampers are still employing temporary magnets which need a magnetic field strength of 150-250 kA/m.
