ABSTRACT:
An apparatus for damping dynamic response in a primary structure, includes a secondary mass, and a spring and a viscoelastic element, the spring and viscoelastic element interposed between the primary structure and the secondary mass. The apparatus may include a housing for the secondary mass, the spring and the viscoelastic element, should the spring, viscoelastic element, or both the spring and viscoelastic element, be interposed between the secondary mass and the housing. A method for damping dynamic response in a primary structure is also disclosed.
