A smart skin structure (100) 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 (102) 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 (102) 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. |
