TAPERED-BAND CONFIGURATIONS FOR SURFACE DAMPING. PART I: ANALYSIS. PART II: PRELIMINARY EXPERIMENTAL STUDIES.
Abstract
Work is extended to the study of tapered bands as unit elements in the stacked-band configuration. The tapered-band configuration leads to damping results similar to the straight-band results of Lazan, et.al., with a somewhat more compact stacking arrangement. Analysis of the tapered-band unit is much more complex than that for the straight-band unit. Comparison of the resulting theory with the straight-band theory and with experiment is given. Using a previously designed multiple straight-band surface treatment as a model, several new multiple-band configurations were designed having constraining layers with tapered cross-sections. From these various designs one was chosen as the test specimen. To examine this treatment, it was attached to the flexplate of a large pendulum assembly, which was then set into oscillatory motion. The rate of decay of the motion was measured and used to determine the damping characteristics of the applied treatment.
