Active control systems of noise and vibrations
INTRODUCTION
EXAMPLES OF APPLICATIONS
Active isolators cancel the incoming vibration by generating a dynamic force of same magnitude in opposite phase
through the use of electrodynamic actuators, thus improving the low frequency performance of the suspension.
through the use of electrodynamic actuators, thus improving the low frequency performance of the suspension.
The objective is to improve the insulation of vibration in the range 10 to 1000 Hz even more – according
to the needs of the application.
The applications of STRACTIVE are endless : reactive silencer, electric motor, transformers, internal
combustion engines, structures, pumps,...
EXAMPLES OF APPLICATIONS
➤Oceanographic research vessel : improves the threshold of sonar detection.
➤Extends crew shift.
➤ Submarines : reduce noises.
➤ Diesel engines / ventilation systems : reduction of air noises by active silencers.
➤ Machine tools : improvement of precision and life cycle of manufacturing tools
ADVANTAGES
