Modal test surveys (EMA, OMA)
To determine the dynamic behaviour of oscillating systems we use experimental modal survey tests (EMA). The available test facility is fully mobile and can hence be used at any suitable test site. Modal survey tests can be accomplished using the step sine or MIMO technology. Sophisticated modal analysis technologies are available to optimally estimate the modal parameters.
We additionally perform so called output-only modal survey tests on basis of data generated during vibration testing using our analysis software.
In recent years also micro vibration characterisations of sensitive test items under simulated space conditions have increasingly gained importance. In this area IABG has developed reliable procedures to accurately determine these micro vibrations.
