Abstract

A damping device comprising a first element in the form of a bolt whose central rod portion, as a spring, forms a primary load path between structural elements between which the damping device is mounted, with a damping element of viscoelastic material loaded in shear between a pair of sleeves and forming a secondary load path, in parallel, with the primary load path to damp vibrations in the structural members.
