Bassocontinuo Aeon

Harmonious shapes and performances without compromises. Carbon main structure (CFRP ENDOSKELETON) and highly cushioning techno gel on which float the shelves (LHPS SHELVES). An innovative and skillful material mix enhances the concept of perfection. REVOLUTION LINE was born to create a new standard and to explode some false myths. It is a product line born and designed to satisfy the most demanding enthusiast (AEON is the forefather and its name means “era” or “eternity”). It is tested with anti-seismic methodologies and certified thanks to cutting-edge devices that spotted its weak points and gave us the chance to fix them and develop a unique project.

AEON – The beginning of a new era

The experience gained during all these years challenged us towards a new goal. AEON was born after we reached it. The new REVOLUTION LINE enters a crowded market but it has that extra oomph. We read every day statements that exceed the concepts of physics basis. It seems that those that exaggerate the most win. Other times someone makes up some miraculous potion that has the only aim to mix up ideas. AEON – and the next devices included in the REVOLUTION LINE – is based on clear physics concepts and on serious data. We have not made up things and we have left nothing to chance. To establish a new standard, it is necessary to respect the consumer: is the rack that we have created the best available on the market? Probably not but we are well aware of what we are about to introduce.

CFRP ENDOSKELETON

Composite materials as system’s frame. Carbon fiber is an anisotropic material (it reacts differently to the different forces that stress it) that is used in the aerospace and automotive industry for its characteristics of high stiffness and lightweight. The CFRP (acronym for Carbon Fiber Reinforced Polymer) ENDOSKELETON is made of a BIDIRECTIONAL carbon and glass fiber sandwich structure reinforced with structural resins. The fibers orientation (optimized thanks to structural and accelerometric tests that have evidenced the critical stress points) made possible the creation of a very light main frame (around 600 grams) able to bear up to 140 times its weight. The CFRP ENDOSKELETON is a MONOCOQUE BODY, namely made of a unique monolithic element made in an aluminium machined solid plate. Monocoque bodies have no structural welding and this is their distinguishing feature. Monocoque bodies are the best that composite market can offer. (F1 cars have a safety airframe that is made using this technology).

LHPS SHELVES

Lightweight High Performance Sandwich is a material mix especially designed to enhance sound performances. Each shelf section has a mono directional carbon fiber shell 1 mm thick and a special polyurethane foam with overlapping epoxy resin that build out supporting ribs. The result is a perfect dispersion of residual vibrations (generated by the sources) in the form of heat, a very high resistance to compression and to static load and an optimum force distribution (as it is demonstrated by the modal analysis). The four techno gel dumpings on which it leans, allow the movement of the shelf in three directions and dramatically reduce direct vibrations generated by the sound pressure.

TSA – Technogel Shock Absorber

To describe this exceptional material we need only few words! Developed by Technogel Gmbh in cooperation with Bayer Chemical Company (it has been widely employed also in our ZEN LINE), Technogel is a unique “soft solid” material that joins together the 3D deformation of a fluid and the memory shape of a solid. It’s a completely non-toxic and stable polyurethane substance (made without using oils or plasticizers), at first developed for the medical field and now used in a wide range of applications. This material, exposed to dynamic stress, has demonstrated a degree of absorption and dispersion unique in its category.

EDT – Encapsulated Damper Technology

BASSOCONTINUO-Aeon-15

Here is the challenge! Where else could we place a high performance rack if not on the only material that can guarantees a very high absorption coefficient? Every foot is adjustable in height thanks to threads 1 point per inch, it has inside an elastomer cylinder 15 mm thick and 3 degrees of constraint (thus it maintains the necessary stability). Thanks to the material’s relative compliance (50 sh.) the foot easily adjusts to the surface and at the same time this compliance absorbs (and disperse in the form of heat) floor vibrations that are the vibrations that have a bigger strength (low frequency transverse waves). A simple but effective solution.

TACHYGRAPHIC CERTIFICATE

BASSOCONTINUO-Aeon-13

A tachygraphic certificate, that comes with every product, guarantees the perfect execution of the autoclave manufacturing process of the endoskeleton (and the shelf). The control of pressure, time and temperature is fundamental to achieve the best results. High temperature and pressure (120 C° and about 6 bars) inside the mould facilitate the hardening of the epossidic resin and the absence of air bubbles in the structure. This same procedure is required in the aeronautical and automotive sector to certify the coherence of the productive process.

TESTING PROCESS: Static structural analysis

BASSOCONTINUO-Aeon-14

To design a rack it is necessary to evaluate, first of all, which is the load that it can bear. AEON is the first rack with a carbon main structure that can bear a very high load (80 kg on bottom shelf, 60 kg on all the others) even if it has a total weight of 635 gr. An amazing result! The breaking point is even more astounding: the CFRP ENDOSKELETON can bear loads 500 times superior to its weight. The deformation curves show a straight trend and a very high static resistance. The deformation is inferior to 2 mm on a 800mm long arm, loaded in its central part with more than 120 kg. With the same load the horizontal deformation is inferior to 0,3 mm.

TESTING PROCESS: Shelf dynamic analysis

The modal analysis of the CFRP ENDOSKELETON and of the LHPS SHELF has been performed with a seismic shaker created to generate the vibrations of a source engine (analog or digital) and to understand what actually happens to a rack that undergoes direct stress. A three-axial accelerometer has been positioned in 42 points of the structure.

In this way we have recreated the vibrational movements obtained stimulating the structure with frequencies included between 20 Hz and 11 KHz. The subsequent analysis of the results evidenced the critical points of the prototype and gave us the opportunity to optimize the orientation of the carbon layers and maximize its performance.

TESTING PROCESS: Dynamic analysis of the structure

Once established the exact composition of the endoskeleton we have done the dynamic analysis of the entire structure. We have used a measuring hammer and four mono-axial accelerometers on 51 selected points so to recreate the structural net. With the EMA (Experimental Modal Analysis) and a dedicated software we have detected the parameters of the resonance frequencies, of the dampings and of the modal warps.

This study evidenced some criticality and gave us the opportunity to solve problems that had never been faced before in this market. The result is a highly performing rack – without compromises – at a very competitive price.

TESTING PROCESS: Transmissibility analysis

BASSOCONTINUO-Aeon-16

This was the most important phase. In this phase we were to find out if the project was correct: for the transmissibility analysis we have prepared a rack simulating a situation of operativity (we have loaded it with asymmetrical weights to simulate the presence of the electronic devices). We have performed the analysis stressing the deck with a seismic shaker able to create frequencies from 1Hz to 18 KHz from the distance of 1 meter. In this case the EDT (Encapsulated Damper Technology) module reacted perfectly and demonstrated its ability to damp vibrations, significantly reducing the peaks.

Today we can affirm that we have, once again, created a beautiful object with the usual high quality that is a trademark of all BASSOCONTINUO products. This rack is also the most technologically advanced device present on the market to this date.
