Abstract:
A method for reducing vibrational energy in a structure having a vibrating member using a vibration confinement device and a vibration damping element, the vibrating member having boundaries and vibrating relative to the boundaries, the method comprising:selecting a vibration confinement region in the vibrating member relative to the boundaries;determining an effective torsional stiffness and an effective translational stiffness for the vibration confinement device;determining an operating position relative to the boundaries for the vibration confinement device on the vibrating member to define a determined position;determining a damping position for the damping element on the vibrating member, within the vibration confinement region;positioning the vibration confinement device at the determined position, thereby confining vibrational energy to the vibration confinement region;positioning the damping element at the damping position of the vibrating member; anddissipating the vibrational energy from the vibration confinement region by the vibration damping element,wherein the vibration damping device is an active vibration damping device.
