Uncontrolled vibration creates multiple problems in metalcutting operations. Varying forces in the cutting process cause vibration and tool chatter that degrade part surface quality, quickly wear or ...

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 ...

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 ...

This is achieved through the continuous measurement of floor vibration, which is countered in real time by expanding and contracting piezoelectric actuators to cancel out floor motion. Initially ...

Large machines typically require attaching their frames or beds to a concrete foundation, often called a reaction or inertia mass. Equipment requiring isolation is ...
