Active devices to attenuate structure born noise with active damping strategy

The stand-alone active damping device (ADD) has been designed to introduce significant damping in all observable structural modes from 20Hz to 2kHz.

The device consists of:
- A sealed electro-mechanical actuator to be attached to the structure to be damped. The actuator also includes a vibration sensor and its conditioning electronics.

- A remote electronic box, including the actuator power electronics and the controller, as well as performance monitoring interfaces.

In-situ integration is simple; up to 15% damping has been achieved on industrial production machines on first attempt without preliminary knowledge of the machine dynamics.
