Application 09/328,918
to confine vibrational energy to the vibration confinement
region of the structure;
a vibration detector disposed on the vibrating member
to generate a vibration signal;
a controller to receive the vibration signal and
generate a confinement device control signal in response
thereto, the confinement device control signal being
transmitted to the active vibration confinement device to
control at least one of the effective translational spring
constant, the effective torsional spring constant and the
selected location; and
an actuator provided on the vibration confinement device to
adjust at least one of the effective translational spring
constant, and the effective torsional spring constant in
response to the confinement device control signal.
32. An apparatus for confining vibrational energy in a
structure having a vibrating member comprising:
a vibration confinement device located in a preselected
vibration confinement region contained within boundaries of the
vibrating member, the vibrating confinement device has an
effective translational spring constant and an effective
torsional spring constant, and confines vibrational energy in the
vibrating member to the vibration confinement region of the
structure, wherein the vibration confinement device is selected
from the group comprising at least one translational spring
attached to the vibrating member to apply translational spring
forces to the vibrating member, at least one torsional spring
attached to the vibrating member to apply torsional spring forces
to the vibrating member, and an active vibration confinement
device.
