Abstract
A vibration isolation apparatus is provided that includes a main spring and a tuned mass damper. The main spring has a first end and a second end, and is configured to resonate when vibrated within a predetermined frequency range with a first axial surge mode having a magnitude. The tuned mass damper is coupled to the main spring at a first axial position located substantially equidistantly between the main spring first end and the main spring second end and is configured to reduce the first axial surge mode magnitude at least 50% when the main spring is vibrated within the predetermined frequency range. Methods of manufacturing the vibration isolation apparatus are also provided.
