Active Vibration Control
Active vibration controller is used in a military aircraft and automobiles to analyze vibrations of the structural members in order to counter the vibrations and hence stabilize the structural members. This is used as part of active maintenance in automobiles, aircrafts and helicopters.
Vibration Stabilizer use Piezoelectric sensors attached at strategic locations of the moving parts feedback the vibrations that are analyzed and piezo electric actuators used to nullify the vibrations. This improves efficiency and life of moving parts.
Four channel vibration sensing
Power Amplified drives
ARM Cortex M4 for digital signal processing
Closed loop vibration control
Up to 1A capacitive load
Why “Active Vibration Control”
PRODUCT IN ACTION
Active vibration controller uses piezo-electric sensors to sense vibrations, sensitive frontend analog electronics sense the vibrations. Signal processing units in the system analyse the vibrations for frequency, phase and amplitude. Power amplifiers drive piezo actuators that apply counter vibrations to the structural member to reduce vibrations. Active vibration controllers are installed.
Aircrafts wings are subject to high degree of vibrations due to wind, active vibration controller installed on the structural member stabilizes this to improve stability.
Helicopter rotors need to function efficiently to improve flight, the rotors are fit with active vibration controllers to reduce wear and tear and hence improve efficiency.
