Textron has developed an active vibration control system for rotor hubs in aircraft, reducing rotor-induced vibrations. The system includes motors driving weights to generate shear forces, controlled ...

Adaptive vibration control encompasses a suite of methods designed to attenuate unwanted oscillations in structures and machinery by dynamically adjusting control parameters in response to changing ...

The aerospace and defense industry continues to be a hotbed of patent innovation. Activity is driven by automation, environmental sustainability, and operational efficiency, and the growing importance ...

Ideally, an optical table’s vertical vibration response on isolators would be a single-degree-of-freedom system. The system would be symmetrical around the vertical axis, and a vertical force through ...

Lord has received its first production contract for active vibration control systems on the Hindustan Aeronautics (HAL) Dhruv Advanced Light Helicopter. The first production helicopter with the ...

Sikorsky Aircraft Corp. in Stratford, CT received a $6.8 million cost-plus-fixed-fee order against a previously awarded basic ordering agreement N00019-03-G-0003 for the development effort to modify, ...

KSI recommends and can offer onsite vibration surveys to determine the environmental information in buildings or facilities. If results indicate vibration amplitudes at frequencies above the equipment ...
