Euronaval 2018: Hutchinson STRACTIVE active noise and vibration control system for submarines and ships.

French Company Hutchinson presents STRACTIVE an active noise and vibration control system for submarines and ships at Euronaval 2018, the International Maritime and Naval Defense Exhibition in Paris, France. The STRACTIVE is fully developed and designed by Hutchinson to reduce noise and vibration aboard submarines and ships.

Active isolators cancel the incoming vibration by generating a dynamic force of same magnitude in opposite phase through the use of electro-dynamic actuators, thus improving the low frequency performance of the suspension. The goal is to improve the insulation of vibration in the range 10 to 1000 Hz even more – according to the needs of the application.

Active structure borne noise control is managed by introducing interior actuators in the transmission paths between the source of noise/vibration and the receiver.

The applications of STRACTIVE™ are endless: reactive silencer, electric motor, transformers, internal combustion engines, structures, pumps, to name a few. It is particularly suited for hybrid and diesel-electric propulsion rafted systems.
