Abstract

The invention discloses an inertia mass amplification type tuned mass damper, and belongs to the technical field of structural vibration control. The inertia mass amplification type tuned mass dampercomprises a hollow box body, an I-shaped mass block, a gear a, a gear b, a rectangular frame, a steel ring, a viscous damper, a steel sheet, a spring, a rotating shaft and a ball. According to the inertia mass amplification type tuned mass damper, inertia damping force is enlarged by adjusting the radius ratio of the gear a and the gear b; damping parameters are conveniently changed by adjusting the mass of the mass block, the stiffness of the spring, and the like; the inertia mass amplification type tuned mass damper has the advantage of small design mass, the adverse effect of excessive additional gravity on a structure can be avoided, and performance of the structure is improved; the inertia mass amplification type tuned mass damper is reasonable in design and small in occupied floor space, can save more use area for buildings, and greatly improve use efficiency of the buildings; and the structure is simple, installation is convenient, and wide application prospects and developmentpotential are brought.

Description

technical field [0001] The invention belongs to the technical field of structural vibration control, in particular to an inertial mass amplifying tuned mass damper. Background technique [0002] With the continuous development of my country's economy and society, the construction of high-rise flexible structures such as super high-rise buildings and transmission towers is booming in my country, and will play an important role in social and economic development for a long time. As a disaster-prone country, my country has always focused on disaster prevention and mitigation design of building structures such as earthquake resistance and wind resistance. Ensuring the safety and comfort of these structures under the action of earthquakes and strong winds has become a key issue that needs to be urgently resolved. As a widely used passive control damper, tuned mass damper is widely used in the field of structural vibration control. However, in order to achieve the predetermined d...
