  • Patent number: 12571447
    Abstract: Disclosed are a multi-directional broadband tuned mass damper and a design method thereof, since a first damping structure and a second damping structure are set on a rigid vibration damping frame, and the first damping structure is provided with a control main frequency, the second damping structure is provided with two control main frequencies, the control main frequency of the second damping structure is greater than that of the first damping structure; under the synergistic effect, the second damping structure mainly effectively broadens the control range for high frequencies, and a plurality of first damping structures control the control main frequency of a low frequency one-to-one, thereby controlling the full frequency, and the extension direction of the first damping structure is the same as that of the second damping structure on the rigid vibration damping frame, ensuring isotropic mass and stiffness distribution characteristics thereof; and furthermore, when using different control frequency range
    Type: Grant
