  • Patent number: 6666108
    Abstract: 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 region permits the structure to avoid the transfer of vibrational energy to particularly sensitive portions of the structure.

  • Patent number: 6564640
    Abstract: A smart skin structure has vibration energy managing and steering capabilities. The skin can be used to managing vibrations in the skin or shell of a system, subcomponent, device, or structure. The skin has sensors coupled to the skin to obtain a response to vibrations. Actuators integral with the skin can be selectively activated to apply forces to the skin to confine or redirect vibration energy to one or more predetermined skin regions. The forces applied by the actuators can be controlled to create confinement power flows. Further, the skin actuators can be controlled using spatial derivatives of the vibration forces. The structure can be used in, but is not limited to, watercraft, aircraft, space vehicles, automobiles, marine devices, industrial machinery, machine tools, home appliances, buildings, bridges, and offshore oil platforms.

  • Patent number: 6424887
    Abstract: A motor noise silencer reduces noise at a source, such as an unbalanced electromechanical motor. The silencer, in one embodiment, comprises a multi-layer shell and an integrated vibration-based cooling system. The shell has an inner layer, a middle sound and vibration absorbing layer, and an external layer. The middle layer offers a soft coupling between the outer and inner layers. Heat trapped within the silencer is channeled out by utilizing a vibratory motion of a source (i.e., motor) and motor support system. The silencer provides noise reduction while providing ventilation using vibration generated by the motor.

  • Patent number: 6394242
    Abstract: Undesirable vibrations are controlled in a mechanical structure by confining the vibrations to one or more specified areas of the structure and then dissipating the confined energy by damping. 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 to select a vibrational energy confinement region. Damping elements are concentrated in the vibration confinement region to dissipate the confined vibrational energy. Judicious selection of the confinement region permits the structure to avoid the transfer of vibrational energy to particularly sensitive portions of the structure, or to direct vibrational energy to a portion of the structure. Optimization procedures are presented for designing structures having optimized placement and selection of the vibration confinement device and damping devices.
