Project factsheet
In Chile high up in the mountains a plant is built with high-tech disk antennas to study the cosmos. Cartridges for detection of different wavelengths are placed in a trump underneath the disk. The cartridges consist of delicate structures and materials for mirrors, lenses and electrical components. The surrounding tower consists of fibreglass. Because the least vibration could possible cause large accuracy loss, possible resonance should be avoided. The natural (Eigenfrequencies) of the structure were therefore calculated, and it was verified that these frequencies were spaciously away from the Eigenfrequencies of the trump to avoid vibration coupling.
For a safe transportation to Chile, the structure was calculated to be able to resist considerable g-forces without causing permanent deformation.
