The HGL Rotational ODS+OMA features a solution to determine the structural parameters Natural Frequencies, Damping and Mode Shapes of rotating parts. This is archieved by the specialized evaluating of measurements conducted used one or more sensors rotationg with the part and a corresponding tacho signal. The transmission of the sensor signals is  done via sliprings or telemetry. The determination of the modal parameters is done by the use of the Operational Modal Analysis, the "OMA" ....
