I. Damper Assembly Description
1. The damper assembly includes a spherical elastomer bearing member, which is operable for accommodating relative motion and vibration.
2. Additionally, the damper assembly features a flat elastomer bearing member, which also operates for accommodating relative motion and vibration.
3. The assembly includes a substantially rigid transition shim disposed between the spherical elastomer bearing member and the flat elastomer bearing member. This shim couples the spherical elastomer bearing member to the flat elastomer bearing member.
4. Furthermore, the damper assembly comprises a tension member attached to the substantially rigid transition shim. This tension member is operable for prepressing the spherical elastomer bearing member and increasing the cocking stiffness of the damper assembly.
