Why vibration measurements?
Dynamics affects all the mechanical structures and equipment and vibration measurements are today the most reliable method to investigate them. The most varied causes originate vibrations: road on a car, turbulence on an airplane, unbalanced shafts on industrial machinery, strong wind on a building, the compressor on a refrigerator, the ignition of the launcher on a satellite, the electromagnetic field on a transformer, …
Despite the many forms they can take, vibrations are always the consequence of a load varying over time. They arise from a complex interaction between external, inertial, elastic and damping forces. They represent an undesirable effect because, in the mildest cases, they cause noise and discomfort. When resonance phenomena are encountered, they can instead generate from fatigue damages up to sudden breaks. Vibrations can also cause pathologies to the musculoskeletal system and exposition levels have to be monitored.
Given the wide variety of possible cases, vibration measurement activities can be very different. They range from the most immediate field surveys of the equipment operations, to modal analyses in which a known excitation must also be provided to measure the resonances of a structure. In Vicoter vibrational investigation can reach the size of a test campaign with the installation of hundreds of accelerometers, the study of numerous configurations and the use of advanced data analysis techniques such as transmissibility of anti-vibration mounts, order analysis, mission synthesis, Operational Deflection Shape (ODS), Transfer Path Analysis (TPA), Operational Modal Analysis (OMA), …
