Abstract:
A system for managing noise and vibration in a vehicle includes a housing defining an internal cavity. A compliant member is attached to the housing and further defines the internal cavity. A magnet is operatively fixed to the housing in the cavity and has a magnetic field. A coil is positioned in the cavity and is configured so that there is relative movement between the coil and the magnet in the magnetic field in response to movement of the compliant member relative to the housing. A resistor is in electrical communication with the coil to form an electrical circuit. Relative movement of the coil in the magnetic field induces a current in the circuit that creates an opposing magnetic field, thereby reducing transmitted dynamic forces.
