Magnetic suspension Reological How does it work?

This type of suspension system for the first time in 2002 by GM on Cadillac Seville STS model was fitted . And then on many other cars including Chevrolet and Buick were built . This product by Audi R8 and TT models that will be unveiled in Germany .

Factor that distinguishes this type of suspension system is the absence of any other types of electromagnetic valves - mechanical . Instead, the magnetic suspension system based on Mgntvryvlvzhykal fluid (MR) is designed . This fluid is a smart fluid that works directly with Mnatys .
MR fluid is oil usually like a tiny magnet particle size in the range of micro- meter is filled . When the magnetic field is influenced by fluid intelligence , so that the fluid viscosity is higher in solid Vyskvlastyk say.

The MR fluid to an average of 20 to 40 % iron , which is based on mineral oil are suspended . The carrier fluid kinetics of oil , water and glycol. This type of fluid is used to prevent fine particles from being deposited seeds Mykrvyy iron .
When the coil vibration absorber ( shock absorber ) is the MR fluid does not enter the energy system , the system is in Off Position smart fluid and the particles are randomly sector . Able to move freely throughout the fluid . In this case , our damper system functions like a conventional suspension system with the old fluid .
On Position Whenever the system is in a magnetic field is applied to the system , the smart fluid inside the damper is applied . In this way, the particles flow along the body of the damper are arranged like a magnet to iron particles in a particular direction to take . The iron particles are usually orientated perpendicular to the direction of fluid motion is smart . Or the viscosity of the fluid resistance force depends on the intensity of the magnetic field and its power.

Thanks to applying the ECU in most cars with different suspension modes that are selected by the driver to switch between states is done in a fraction of a second . Vehicle and the road condition monitoring sensors and the controller to the damper characteristics close to 1,000 times per second to change .
For example , consider the Audi TT . Normal or Sport mode, the driver can press a button to change your suspension . In this mode the dampers respond with the appropriate choice of state gives itself . In fact, according to the driver selection decisions ECU to determine the damper characteristics , need to perform the reaction vehicle . Using MR fluid drive ensures stable and better for you . The Vehicle Stability Control system in different climatic conditions and the road is completed . Despite the MR fluid ECU computer system can generate a wide range of Damping forces and rapid response appropriate to apply .

Among the advantages of magnetic fields can be pointed to the lack of effect of temperature on it . MR fluid range between - 40 ° C to 105 degrees Celsius .
The biggest disadvantage of this system is its cost . So far just over half a million vehicles worldwide Mgntvryvlvzhykal suspension is installed . No doubt the problem is gone, the cost of this system is definitely the best of the suspension system . Since cars Acura MDX, Audi TT, Audi R8, Cadilac DTS, SRX, STS, Chevrolet Corvette, Ferrari 599 GTB and Holden HSV Commodore suspension of benefits.

It is likely that the fluids in the car next Smart Car clutch be used by the system by pressing the push-button 4WD vehicles can have many applications .
