ACTIVE INERTIAL DAMPER SYSTEM AND METHOD

ACTIVE INERTIAL DAMPER SYSTEM AND METHOD

An active inertial damper system (100) and method for damping vibrations (V1,V2) in a structure (11). An inertial mass (2) is supported by a support frame (1) via spring means (3) to form a mass-spring system (2,3) having a resonance frequency (fn). A controller (6) is configured to control a force...

Zusammenfassung:An active inertial damper system (100) and method for damping vibrations (V1,V2) in a structure (11). An inertial mass (2) is supported by a support frame (1) via spring means (3) to form a mass-spring system (2,3) having a resonance frequency (fn). A controller (6) is configured to control a force actuator (4) to adapt the driving force (Fd) as a function of measured vibrations (V1,V2). The controller (6) comprises a filter (H) determining a magnitude (M) of the driving force (Fd) as a function of frequency (f) for the measured vibrations (V1,V2) in the structure (11). The filter (H) is configured to provide an anti-resonance dip in the magnitude (M) of the driving force (Fd) at the resonance frequency (fn) of the mass-spring system (2,3) to suppress resonant behaviour of the mass-spring system (2,3) itself.
