Usually, ESA shake tables are used to replicate the take-off vibrations of a satellite. The large object observed here does not apply to satellites. Here is an 8-ton cooling system passing through an earthquake simulation.
Made in Belgium, and the parameters cover 6 x 4 x 5 m. Designed to eliminate heat from industrial data centers, using only 5th of the energy of traditional structures.
The system stayed in the 3-hour journey to the ESA test center (Noordwijk, the Netherlands) in order to pass the test and prove that it can function even with earthquakes with peak acceleration in 1G on 3 axes, which exceeds the situation in Fukushima in 2011 For promotion in the Japanese market, it is especially important to take care of earthquake resistance. For testing, the multi-axis hydraulic device Hydra was used - one of the most powerful in the center. Hydraulic drives move the 18-ton shake table in all three orthogonal axes at the same time, like an airplane simulator. Movement is controlled by a network of 36 parallel computers. Installation is fixed by seismic mass, supported by springs and shock absorbers. During testing, you can use 512 channels of measurement of acceleration.
The ESA Testing Center in the Netherlands is the largest of its kind in Europe and provides a full range of equipment for all aspects of satellite testing.
