ABSTRACT:
A damped instrument kinematic mount providing novel damping features to protect instruments from damaging flight loads. The mounting scheme utilizes any number of identical strut elements to greatly reduce manufacturing complexity and costs. Improved kinematic mount performance is achieved by arranging the six strut configuration to approximately uncouple the mount suspension modes. A spherical joint damper is located at strut flexure locations and utilizes a viscoelastic damping material that deforms in shear. Alternatively, cylindrical slot mount dampers are placed at strut flexure locations. The cylindrical slot mount dampers use o-rings or washers placed within the slotted machined mount bar stock. The kinematic mounts can then be arranged in a classical truss arrangement pattern or other configuration providing desired damping characteristics.
