Latest Patents: One of Liu's key patents is the "Multi-directional broadband tuned mass damper and design method thereof." This invention discloses a multi-directional broadband tuned mass damper that incorporates a first damping structure and a second damping structure on a rigid vibration damping frame. The first damping structure is designed with a control main frequency, while the second damping structure features two control main frequencies, with the second structure's control frequency being greater than that of the first. This synergistic design effectively broadens the control range for high frequencies, while multiple first damping structures manage the control main frequency of low frequencies. The isotropic mass and stiffness distribution characteristics are ensured by aligning the extension direction of both damping structures on the frame. Furthermore, the design allows for pre-configuration of the number and distribution of damping structures to meet varying control requirements.
