AnemOSC

Oscillator generated by string tension and wind power.

The anemOSC consists of 5 elements:

Lashing straps.
Two stakes 1.30m (steel 10/20 from 3 / 4 ")
Four carabiners.
Four strings of reinforcement.
Stakes..

AnemOSC project consists of 3 stages:

Implementation and preliminary tests.
Test with appropriate experimental conditions and re-evaluation
Software development hardware.

1. Implementation and preliminary tests.

El anemOSC fue probado en mayo/ 2008:

3 knots (6 Km/h). in Punta de Lobos / Pichilemu / VI región / Chile. --Pronstics--.

3 knots(6 Km/h) in Santo Domingo / V región / Chile. --Pronstics--.

First experiments showed that anemOSC works perfectly and that the limiting factor so far is wind.

The ideal is to activate it with a minimum of 22 knots (41 km / h), which condition occurs between October and January. It is expected that the great tension of the tie strap and strong winds causing severe vibration that would come into resonance at times generating frequencies between 60-80 Hz that emerge between harmonic frequencies given by the sound of the wind. This is a psycho-acoustic experienc

Además la cuerda (correa de amarre) debería graficar la frecuencia resultante incluyendo los armónicos que se generen.

2. Test with appropriate experimental conditions and re-evaluation.

This second stage will take place between October and January or in the event of power to implement it in optimal wind conditions (22 knots).

AneOSC Once installed on the site with the right conditions, are measured, first, the wind conditions optimal for different tie straps and on the other hand, the response of the various belts (thickness, length Material, thickness). Frequency is measured by microphones previously filtered and analyzed the possibility of measuring frequency by other means (persepción of participants and sensors to the date of this report is still being evaluated)

3. Software development hardware. .

With data from previous phases, will proceed to the generation of a new structure that would remove the "key " or "ratchet adjustment" and fix the straps tie at fixed distances with adjustable tension system.

The belts are tensioned by an electric winch to be activated from the outputs delivered by the sensors that capture the frequency of oscillation of anemOSC. This tension can be generated and therefore the swing you wan
