Vibration control by confinement of vibration energy

摘要

Undesirable vibrations are controlled in a mechanical structure by confining the vibrations to one or more specified areas of the structure. Vibration confinement is achieved using a confinement device which effectively applies both translational and torsional forces to the structure. The strength of the translational and torsional forces, and the position of the confinement device are chosen by the designer to select a vibrational energy confinement region. Judicious selection of the confinement a region permits the structure to avoid the transfer of vibrational energy to particularly sensitive portions of the structure.
