Scope

This standard recommends the method of measuring mechanical admittance and other frequency response functions by using a vibrator not connected to the structure to generate pulse excitation, and provides basic guidelines for selecting and using measuring and analyzing instruments. This standard is applicable to the accurate measurement of admittance, acceleration admittance and displacement admittance under shock excitation, which can be used for both driving point admittance measurement and transfer admittance measurement. Shock excitation method can also be used for rough measurement of frequency response function. The signal analysis methods involved in this standard are all based on discrete Fourier transform, and their application scope is only limited by the ability and experience of the instruments implementing these methods, and does not exclude the use of other methods currently under development.
