Vibration suppression

Suppression using inerters

The Group develops passive vibration suppression devices with a recent emphasis on using inerters.

An inerter is a two-terminal element, with the property that the force applied is proportional to the relative acceleration across its terminals.  It completes the mechanical-electrical force-current analogy, providing the mechanical equivalent to a capacitor. The device is geared with the result that its apparent mass is far greater than the actual mass of the device.

Semi-active dampers

Semi-active dampers were conceived in early 1970s as controllable devices with time-variable dissipative properties. Since then these devices were closely studied, developed and applied.

Electro-hydraulic and magneto-rheological semi-active dampers received major attention in the research group. Electro-hydraulic dampers were investigated in the context of load and vibration control in helicopter rotors in collaboration with AgustaWestland.
