CF-5200 Frequently Asked Questions

Question number FAQ-0597

The criteria for determining the natural frequency based on data obtained from impact tests, including FRF, PHASE, and COH, are as follows.

The MAG data from FRF does not have clear peaks, and at higher frequencies, the way measurements are taken can cause peaks to be flattened, making it difficult to make judgments.

It is necessary to change the method of supporting the test samples at the impact position and to make a comprehensive judgment based on a large amount of measurement data.
