Ever had a workshop day where tools suddenly feel off? The impact wrench hits softer. The spray gun loses its edge. Someone adjusts the regulator, someone blames the hose, and work slows down. Most times, it comes down to one thing: the compressed air supply struggles when your bays get busy. ELGi has seen this play out across workshops that expect their compressed air to stay steady under pressure.

The article describes a diagnostic method, on the basis of which it is possible to assess whether there is a loose connection in the clamping system (detection) and to determine which of them is loose (localization) and what extent of release occurred (quantification). The diagnostic method is based on comparing the drops in the natural frequencies of a measured system with respect to a reference system, which simulates the desired state. When analysing the drop in natural frequencies in order to locate the loosening, it is necessary to relate this drop to the position of the clamping joints within the considered mode shape. To determine the extent of loosening, it is necessary to know the relationship between the changes in natural frequencies and the modeled loosening of clamping joints.
