The birth of a revolutionary vibration isolation technology

Z-Damper is a vibration isolation system able to act as a dissipater and also to enhance the performance of any damping solution by mechanical impedance coupling.

This magneto mechanism is adaptable to low and high ranges of frequencies and it can substitute tuned vibration absorbers currently being used for the vibration control in automotive, energy or seismic applications.

Unlike other existing damping technologies, Z-Damper is capable of maintaining an optimum performance at extreme temperatures.

extreme temperature dampingThe EU funded FP7 Clean Sky program is boosting new technologies in order to improve safety and reduce the contamination levels of the aircraft systems. One of Clean Sky major projects is the development of a new counter-rotating open-rotor (CROR) engine capable of minimizing both noise and fuel consumption.

As the main project partner, Airbus is searching for technologies able to meet the exigent standards required for this large-scale project. Specifically, the fuselage-mounted turbofans need a very efficient isolation system to assure a reduction in the transmission of the vibrations to the aircraft structure. However, present damping technologies have a big limitation: they are not able to operate at the extreme temperature that the rotor engine may reach.

MAG SOAR in collaboration with Universidad de Alcalá has developed and tested three different prototypes specially optimized to reach Airbus requirements. Z-DAMPER project final meeting took place in UAH facilities. MAG SOAR and UAH researchers exposed to Airbus engineers the excellent vibration mitigation results obtained from the static and dynamic tests at temperatures up to 200ºC.Airbus-Z-Damper

Airbus, UAH and MAG SOAR teams were clearly satisfied by Z-DAMPER potential. "Z-Damper has demonstrated a unique damping performance, even in extreme temperature environments. We have insight the birth of a new vibration isolation technology which applications are only starting to be foreseen", stated Dr. Valiente, technical director of MAG SOAR and main project technical partner.

MAG SOAR presents Z-DAMPER in ESA 2016 mechanism workshop

MAG SOAR technical director exposed the project last advances to the interested parties

The Workshop on Gear Technology and Mechanisms Final presentation took place on ESA´s technical heart and incubator of the European space effort: The European Space Research and Technology Center, ESTEC, located in Noordwijk. (Netherlands)

The objective of the Workshop Gear Technology was to promote the discussion and exchange of ideas between European industry and academic institutions about research related to gear technology. Afterwards, the ESA Mechanisms section hosted the annual Final Presentation Days to disseminate the results of research and development activities.

Dr. Ignacio Valiente, MAG SOAR technical director, made a presentation about the last advances of FP7 Cleansky Z-Damper project. Z-Damper is a new damping technology able to resist extreme levels of vibrations at higher temperature than any other vibration control system. Z-DAMPER working principle is based on mechanical impedance coupling. This represents a completely original concept for vibration control as impedance matching has never before been used for damping purposes. Impedance coupling damping technology can be applied to vibrations control in many other fields such renewable energy or automotion. The working principle is detailed on the recently published paper: Z-Damper: a new paradigm for attenuation of vibrations.
