Abstract
A damper mechanism was developed that provides high damping performance across a broad range of use by applying a preload force on the dynamic damper spring. The dynamic damper spring is located radially between the primary damper, which is positioned on the outside diameter, and the secondary spring positioned on the inside diameter. The damper mechanism was developed with preload and clearance settings configured for ease of assembly. The dimensions and increase in number of parts were also held down while realizing high damping performance and low inertia mass.
