Steam turbine rotors are susceptible to bending during some operational evolutions, which can lead to excessive vibration and ultimately failure. Rotor bending that results in premature failure of ...

Sleek wind machines both on land and in the ocean intrigue many people. The units provide clean energy and contribute nothing to climate change. However, the early history of wind power in the U.S.

The same technology that vibrates cell phones and is used to counter vibrations locally in helicopter cabins could soon be used to better attenuate the shaking motion at the rotor hub, saving weight ...
