Distributed Smart Material Arrays For Low Frequency Broadband Active Noise And Vibration Suppression In Vehicles And Light Structures

The subject of the project is the creation of an integrated modular system of active reduction of a wide range of low-frequency vibrations and noise for use in transport and other related applications.

Active systems have many advantages over classic passive systems, such as the ability to adapt and address the entire range of frequencies, as well as low weight and volume.

The system is based on consumed actuator components of two types of intelligent (electrically active) materials:

  • Piezoelectric materials capable of exerting large forces over a wide range of frequencies, with the main objective of controlling mechanical oscillations.
  • Electroactive polymers, which will be used to create specialized speaker arrays for noise control.
