New damping technology based on mechanic impedance matching

Conventional vibration control technologies are still highly limited. Current damping systems fail to deal with low frequency ranges and extreme temperature scenarios.

In order to fill that gap MAG SOAR has developed a new technology able to enhance the performance of any vibration damping system by mechanical impedance coupling. Impedance is a term usually applied to electronics that represents the opposition or voltage that a circuit presents to a current; the equivalent to the resistance in direct current. Electrical engineers use transformers to multiply voltage and divide current or vice versa in order to adjust the circuit impedances and optimize the circuit power. The same concept can be defined for mechanical systems as Force to Speed ratio. However, up to now nobody has developed any effective analogue mechanical transformer to enhance the efficiency of a mechanical system.

Our ears: A perfect example of mechanical coupling

Surprisingly, nature offers a perfect example of mechanical impedance matching. Ears of most terrestrial animals are provided with mechanical impedance transformers. While the medium in the outer ear is obviously air, the medium in the inner ear is a liquid similar to water. Both of these elements present quite different mechanical impedances. Because of the difference in the impedances of the air and the liquid in the inner ear, an audition loss of about 30 dB should be expected. However, a set of small bones in the middle air (hammer, incus and stapes) compliantly attached, together with the different areas of the tympanic membrane and the oval window provides a mechanical advantage so that it compensates this audition loss. This mechanical impedance coupling is an example of mechanical transformer.

How does Z-Damper works?

Z-DAMPER follows the same working principle detailed on the paperZ-Damper: A New Paradigm for Attenuation of Vibrations”. This contactless magneto mechanism multiplies the input speed and reduces drastically the incoming force needed to achieve the necessary damping coefficient. Z-Damper technology can be used to control the vibration transfer in different mechanisms and to enhance other damping systems efficiency. It is also able to function at extreme temperature, higher and lower than any other damping system.

The northen lights are caused by the interaction between magnetic fields.

MAG SOAR BLOG TAKES OFF!

The magnetic energy´s faculties can be breathtaking. One of the most impressive proofs of this is the phenomenum know as the Northen Ligths, caused by the collision between the earth´s magnetic field and the solar wind. The acelerated electrons crushing against the atmosphere happen to offer us one of the most beautiful spectacles in the entire world.

The great potential of magnetic systems

MAG SOAR is well aware of the great potencial of magnetic force and that´s the reason why magnetism is used as main ingredient in the development of contactless mechanical systems which aplications range from aircraft mechanisms to space systems.

It all begun with the MAGDRIVE project, a magnetic gearbox optimized to work in cryogenic environments. The objective was to design, build and test a magnetic-superconductor non contact drive able to function at extremely low temperatures.

The results were outstanding: MAGDRIVE didn´t only satisfactorily pass every test but it also exceeded the initial expectations. The drive superconducting magnetic bearings were proven capable of suppressing every contact between moving parts. The lack of friction almost eliminates the fatigue of the system, one of the primary causes of the reduction of life time in all kinds of mechanical devices. Furthemore, it realeases the machinery from the constant need of lubrication and improves its efficiency.

The consequences and applications of this innovative system are countless. That is the reason which encouraged the team behind MAGDRIVE to create the spin-off company MAG SOAR.These are some of the products developed by MAG SOAR engineers:

To sum up, MAG SOAR´s objective is to take advantage of electromagnetic properties in order to unravel complex industry problems that traditional technologies have been unable to solve such as the high costs of maintenance and lubrication, mechanic limitations on extreme temperatures, problems caused by wear or fatigue…  In essence, MAG SOAR aim is to prove that magnetic systems can be the perfect choice to build and improve the present´s technology.
