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 ...

Traditional isolators are built with metal springs or rubber blocks. They have low internal damping and generally are only effective at frequencies near 10 Hz. They also offer little to no isolation ...

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 ...

Vibration motors are the silent workhorses behind tactile feedback in wearables and handheld devices. These compact actuators convert electrical signals into physical cues, enriching user interaction.

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 ...

An accelerometer-based active vibration-control system for CNC machine tools is designed to improve machining productivity by maximizing material removal rate (MRR), with the result that tool-head ...

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