Active Vibration Control Demo

Vibrations and related noise are always increasing in today vehicles. Indeed, engine downsizing, cylinder deactivation, Start & Stop and more generally powertrain electrification are new sources for NVH which disturb the passengers. Active cancellation of the vibrations generated by the powertrain is more and more considered by car manufacturers and we see more and more vibrating linear actuators in active mass damper or in active engine mounts. MMT has developed such vibrating actuators based on a moving magnet principle and we have built a demonstrator which shown in the video hereafter
