Title:
KINEMATIC MOUNT FOR ATTENUATION MACHINE
Document Type and Number:
Japanese Patent JPH11174173
Kind Code:
A
Abstract:

To obtain a kinematic mount where a new attenuation function is mounted, by arranging an attenuation means and a mechanical support means so that desirable performance characteristics can be provided.

A bending region 62 is formed by the notch of a bar stock used as a machine-supporting means. A spherical damper 46 is constituted of two partial shells 48 and 50 that are arranged concentrically. The partial shells 48 and 50 are mutually connected by a relatively soft layer 52 made of a viscoelastic (VEM) attenuation material being joined to the inner surface of the shell 48. The spherical damper 46 is deformed under a lauching load. Any bending operation at the center of a rotation operates the spherical damper 46 by causing the attenuation viscoelastic layer 52 to be subjected to shear deformation and hence scattering a vibration energy in the form of heat. By selecting an appropriate VEM, a considerable degree of attenuation can be achieved in a suspension vibration mode.
