Abstract
A method of determining damping performance of an article of manufacture includes moving an article of manufacture along a production line, directing a laser beam at a surface of the moving article and then measuring the velocity of a reflection of the beam simultaneously with measuring vibrational excitation in an environment of the production line. The method then includes calculating the damping performance of the moving article of manufacture based on the velocity and vibrational excitation measurements. The calculated damping performance may also be based on a predetermined correlation factor of damping performance of a reference article calculated based on the online system compared with damping performance of the reference article calculated in a controlled offline environment. A system for determining damping performance online is also provided.
