Magnetic suspension can adapt to uneven road surfaces several hundred times per second, in fact it takes only a few milliseconds to adjust any one of the shock absorbers. As the viscosity of the liquid changes, it offers a difference in the damping. Another benefit is that these dampers easily offers the best of both worlds in the ride comfort/handling compromise that many other suspension systems are subjected to. However, several possibilities exist to make levitation viable, for example, the use of electronic stabilization or diamagnetic materials (since relative magnetic permeability is less than one 4 it can be shown that diamagnetic materials are stable along at least one. Magnetic dampers are designed with similar dimensions and connection points to other types of dampers so they are usually attached to the chassis of the vehicle similar to how a coil spring suspension would. If two magnets are mechanically constrained along a single axis, for example, and arranged to repel each other strongly, this will act to levitate one of the magnets above the other. Servomechanisms edit The Transrapid system uses servomechanisms to pull the train up from underneath the track and maintains a constant gap while travelling at high speed Main article: Electromagnetic suspension The attraction from a fixed strength magnet decreases with increased.

Eddy current damping (conductive metal influenced by field) tuned mass dampers in the levitated object electromagnets controlled by electronics Methods edit Mechanical constraint (in this case the lateral restrictions created by a box) can permit pseudo-levitation of permanent magnets For. The servo controls keep it safely at a constant distance from the track.

Induced currents edit Main article: electrodynamic suspension These schemes work due to repulsion due to Lenz's law. Magnetic suspension or magnetic ride control is used by a range of Cadillac vehicles and several other high end vehicles from General Motors (GM) like the Chevrolet Corvette. EMS magnetic levitation trains are based on this kind of levitation: The train wraps around the track, and is pulled upwards from below. Delphi Automotive ha sido la encargada de desarrollar la primera aplicacin industrial de un fluido cuya viscosidad vara ante la presencia de un campo magntico y lo ha denominado MagneRide. 6 Halbach arrays are also well-suited to magnetic levitation and stabilisation of gyroscopes and electric motor and generator spindles. Eddy current damping (conductive metal influenced by field) tuned mass dampers in the levitated object electromagnets controlled by electronics Methods edit Mechanical constraint (in this case the lateral restrictions created by a box) can permit pseudo-levitation of permanent magnets For. This effect requires non-ferromagnetic but highly conductive materials like aluminium or copper, as the ferromagnetic ones are also strongly attracted to the electromagnet (although at high frequencies the field can still be expelled) and tend to have a higher resistivity.

An electrical charge is sent to the liquid in the absorber which immediately changes the position of the particles in the liquid and its viscosity. Either system represents examples of ElectroMagnetic Suspension (EMS). Mechanical constraint (pseudo-levitation) edit With a small amount of mechanical constraint for stability, achieving pseudo-levitation is a relatively straightforward process. This ensures a comfortable ride along various road surfaces.

The forces acting on any paramagnetic object in any combinations of gravitational, electrostatic, and magnetostatic fields will make the object's position, at best, unstable along at least one axis, and it can be unstable equilibrium along all axes. Mechanical constraint (pseudo-levitation) edit With a small amount of mechanical constraint for stability, achieving pseudo-levitation is a relatively straightforward process. Nuestras estanteras son ideales para colocar todo tipo de cosas, desde objetos bonitos que quieras exponer hasta productos bsicos que necesitas tener a mano. From Earnshaw's theorem at least one stable axis must be present for the system to levitate successfully, but the other axes can be stabilized using ferromagnetism. An especially technologically interesting case of this comes when one uses a Halbach array instead of a single pole permanent magnet, as this almost doubles the field strength, which in turn almost doubles the strength of the eddy currents. Magnetic suspension reduces vibrations, bouncing, noise and body roll very effectively on all road surfaces and at any speed that the vehicle could travel. Another geometry is where the magnets are attracted, but constrained from touching by a tensile member, such as a string or cable. Litz wire made of wire thinner than the skin depth for the frequencies seen by the metal works much more efficiently than solid conductors. An electrical charge is sent to the liquid in the absorber which immediately changes the position of the particles in the liquid and its viscosity. Many systems use magnetic attraction pulling upwards against gravity for these kinds of systems as this gives some inherent lateral stability, but some use a combination of magnetic attraction and magnetic repulsion to push upwards.

Static stability edit Static stability means that any small displacement away from a stable equilibrium causes a net force to push it back to the equilibrium point. This effect requires non-ferromagnetic but highly conductive materials like aluminium or copper, as the ferromagnetic ones are also strongly attracted to the electromagnet (although at high frequencies the field can still be expelled) and tend to have a higher resistivity. These kinds of systems typically show an inherent stability, although extra damping is sometimes required. For example, the magnetic pressure of a magnetic field on a superconductor can be calculated by: where is the force per unit area in pascals, is the magnetic field just above the superconductor in teslas, and 4107 NA2 is the permeability.

MagneRide is an automotive adaptive suspension with Magnetorheological damper system developed by the Delphi Automotive corporation 1 2 and now owned by Beijing. Stable magnetic levitation can be achieved by measuring the position and speed of the object being levitated, and using a feedback loop which continuously adjusts one or more electromagnets to correct the object's motion, thus forming a servomechanism.

Although this type of suspension offers a very comfortable ride, sport settings can be applied or tuned into the system to cater for performance vehicles. Other companies, such as Ferrari and Audi are also known to use magnetic suspension in their vehicles.
