> The Rincent Nord-Pas-de-Calais agency associated with Rincent ND Applications have performed a diagnosis of the quality of the fastenings of 42 facade cladding panels of a building.
Altogether 236 points were tested.
These tests consist of:
> to emit a pulse shock using a hammer equipped with a force sensor,
> to record, the vibratory response of the panels,
> after mathematical processing of the signals obtained, to analyze the curve V/F, result of the test, as a function of the frequency.
The "singular" points are highlighted by a high signal amplitude, associated with a low stiffness.
The analysis results in the examples of joined reports, with a color scale based on the calculated stiffness values.
