Applications/Examples of results
One of the most important steps in preparing for impact measurement is determining the reference points. The purpose of selecting reference points is to adequately capture all relevant modes of the chosen points. The decision-making process is often based on individual experience, numerical simulations, or visual assessments of measurement data. However, this approach can be very labor-intensive and prone to errors. Choosing the wrong reference point can lead to modes being missed or insufficient detection, which may adversely affect the quality of the results. These errors are often not recognized until the later stages of modal analysis, and in the worst case, modes may not appear in any transfer function and go completely unrecognized. Making corrections or repeating modal analysis measurements is a waste of time and cost.
