Abstract:
A method of measuring vibration damping of a part, comprising the steps of:(1) vibrating said part at a selected frequency, with a vibrator located adjacent a test portion of said part;(2) measuring an amplitude of vibration of said part during said vibrating;(3) deactivating said vibrator such that said amplitude decays;(4) measuring a decay time of said amplitude over a selected range of decay;(5) repeating each of said steps 1, 2, 3 and 4 with said vibrator respectively located adjacent each one of a series of spaced apart test portions of said part to obtain a series of decay times; and(6) determining a value associated with said series of test portions representative of vibration damping of said part and related to said selected frequency.
