Abstract
A method for measuring the vibration damping of a part. The method comprises the steps of vibrating the part with a contactless vibrator, measuring the output vibrations of the part with a contactless measuring device, determining an input frequency for testing the part, the input frequency being a frequency which uses the smallest gain to cause the part to produce vibrations having an output amplitude equal to a predetermined target amplitude, providing an input to the part with the contactless vibrator such that the part vibrates at the input frequency, simultaneously interrupting the input and using the contactless measuring device to measure as a function of time an output amplitude of vibrations in the part, and determining the rate at which the vibrations in the part are damped.
