Two Methods of Determining Damping of Free, Damped Systems.

reportActive / Technical Report | Accession Number: ADA060244 | Open PDF

Abstract:

This memorandum discusses a comparison that was made of two methods of determining damping coefficients of a free, damped system. Although both methods have been used in the calibration of the electronic circuitry that was used in the tests, they may also be used in mechanical damping tests of plates, beams, structures and materials.
