Abstract
A vibration damper includes a suspended mass connected to a pipeline or similar structural member by a support ring and an assembly of interconnected, generally cylindrical damper members formed of an elastomer material suitable to be stressed in shear. The damper assembly is of modular construction so that the damper can be easily tuned to particular frequency and amplitude conditions of different pipes and spans, respectively.
