ABSTRACT:
A method of determining damping coefficients for a resilient web, involving: stretching a prescribed length of the web between a pair of pulleys mounted on a frame; attaching a prescribed test mass M.sub.0 upon this length at a prescribed distance L.sub.1 from one pulley; shaking the frame at resonance frequency f.sub.R, and the while deriving resonance-amplitude; and using the foregoing to determine web damping coefficients.
