CF-5200 Frequently Asked Questions
Question number FAQ-0597
The criteria for determining the natural frequency from the data obtained by impact testing to determine FRF, PHASE, and COH are as follows:
The FRF MAG data lacks a clear peak, and because of the high frequency, the peak may be distorted depending on the measurement method, making it difficult to make a judgment.
It is necessary to make a comprehensive judgment based on a large amount of measurement data, by changing the striking position and the method of supporting the test specimen.
