Intelligent Vibrations

Basically, the only new principle involved is that instead of the power being generated by the relaxive motion of conductors and fluxes, it is produced by the modial interactions of magneto-reluctance and capacitive directance.

What is so special about (2^64-1)?

It is the root of a story I heard when I was a kid that sparked an interest in me in math. One of my first early steps to becoming an engineer.

Was it the number of corn grains to be paid for the invention of the chess game?

From the technical point of view you rae wrong in the explanation of the ways it works.

"From the technical point of view you rae wrong in the explanation of the ways it works."

What then is your correct explanation?

The correcting systems induce forces in the structure. Those forces are either generated between parts of the structure or they take as "reference" additional masses especially in case of high frequencies. Such forces can be generated by different types of motors. In bridges for instance the cables are tensioned more or less with help of hydraulic cylinders in order to reduce effects of wind or vibrations generated by the moving load. In other systems the reference mass is bound with the structure via an electrodynamic motor or via piezo linear motors. The motors are piloted either by force or acceleration measurements. In fact the system tries to generate a phase shift of 180° between the disturbance and the compensating effect. Imagine 2 loud speakers connected mechanically to each-other. One provides the first with a signal which moves the membranes, on the membranes an accelerometer determines the acceleration and this signal is used to control the current through the second loud speaker in such a way that the membranes will have the lowest acceleration possible. The second coil motor will compensate the forces generated by the first. Of course since the system is active it depends on the apparition of an error signal (acceleration in this example) and since it needs an error to react it will not compensate totally the disturbance.

In the bridge systems the tension in the cables is measured by force ring transducers and the variations are used to pilot the pressure in the cylinders. I simplify but the principles are correct. The reductions are very spectacular they can reach 80..90% of the amplitudes without compensating systems.

This appears technically correct, so far as it goes. The real challenge with using intelligence to damp out vibrations is that the reaction time of the system is often much longer than the vibrations it is trying to control, which means that Fourier decomposition may need to be enhanced by predictive algorithms.

But I suggest you follow the link in post #3 for a full and elegant description of the mechanical aspects of the system that you described.

I remember a study made several years ado by an MIT team. The conclusion (one of them) was that a conference is highly appreciated when nobody understands what was said. There is a general feeling that if one does not understand the level is very high and nobody has the courage to say "what do you mean?"

Yes, I have attended such conferences (the first such being on Dielectric Waveguides). Fortunately, there has always been someone there who has the knowledge and the strength of character to cut through the carp with an apparently innocent question. (Once you've seen it a couple of times, you can learn when to do that yourself)

Regarding the present thread, I believe that the barrackers understand the actual topic all too well.

Not to mention the Turboencabulator which is a necessary accessory when dealing with magneto-reluctance and capacitive directance.

This marvelous component was concieved over a half century ago and described in detail, "The Turbo-Encabulator in Industry," by J. H. Quick, in Student's Quarterly Journal, Institution of Electrical Engineers, London, 1944.

The Turbo-Encabulator in Industry

Wunderbar historetic contrabulation. Do you know where I can find an example for my collection of technical artefacts?

Regret that J. H. Quick is the only known expert on the Turbo-Encabulator. There are no know surviving examples with the possible of exception of one of the UK contributors to the CR4 Forums.

He told me that he had a repository of rare antiques, artifacts, etc. that defy description in a vault 3 m X 3 m X 3 m. It just may be possible that he has the only surviving example of the Turbo-Encablator!

Sometimes, I really enjoy being a nerd.

"artefacts, etc. that defy description"

Clearly not including the turbo-encablator, then - since JHQ described it in such loving and lucid modern verse.

And I don't believe there would be space in such a modest vault for any other items if it included the version with the hydrocoptic marzelvances - which is most certainly the one that I would desire - had I sufficient space.
