Platelike Dynamic Vibration Absorber.

The patent application describes platelike dynamic vibration absorbers for providing vibration suppression. Optimum values of their tuning and damping are specified. The dynamic absorbers are comprised either of a circular or an annular damped plate that is loaded at its outer perimeter by a rigid annular mass. The plates, which act as combined spring-and-damper components for the absorber systems considered, are attached either at their midpoint or around their inner perimeter to the vibrating item or structure of concern. The platelike absorbers are effective in suppressing the transmissibility at resonance across a mass-spring vibrator, and across circular and rectangular plates that have small internal damping and that are used to simulate bulkheads and panels.
