Anti-vibration structure of barrel

Abstract

The invention relates to an anti-vibration structure of a barrel, and belongs to the technical field of vibration reduction of structural engineering. The anti-vibration structure comprises a barrel wall. Foundations are mounted at the upper end and the lower end of the barrel wall. A prestressed cable is fixedly connected between the two foundations. Multiple vibration reduction mass balls are fixedly mounted on the prestressed cable. Each vibration reduction mass ball and the barrel wall are connected through multiple damping consumption devices. The prestressed cable is arranged on the foundations between the top end and the bottom of a wind power tower, the vibration reduction mass balls located on the prestressed cable are connected to the barrel wall through the damping consumption devices, and therefore a damping vibration reduction structure in a shape of sugarcoated haws on a stick is formed; and the effect of vibration reduction is achieved through inertia force generated bymotion of the vibration reduction mass balls, and therefore the rigidity of the tower structure is improved.

Description

technical field [0001] The invention belongs to the technical field of structural engineering vibration reduction, and in particular relates to a cylinder vibration reduction structure. Background technique [0002] The tower structure will be subjected to strong wind loads and earthquakes during service, and the vibration forms mainly include lateral bending vibration, front and rear bending vibration and torsional vibration. The traditional seismic design method of structures relies on the strength, stiffness and ductility of the structure itself to resist the earthquake, but when the earthquake intensity reaches a certain level, the building structure will produce a large plastic deformation that cannot be recovered. Seismic design methods are neither economical nor expected. If the seismic performance of the structure is to be improved, the structure needs to have better energy dissipation capacity, but the final residual deformation of the structure must be very large....

Problems solved by technology

The traditional seismic design method of structures relies on the strength, stiffness and ductility of the structure itself to resist the earthquake, but when the earthquake intensity reaches a certain level, the building structure will produce a large plastic deformation that cannot be recovered. Seismic design methods are neither economical nor expected

If the seismic performance of the structure is to be improved, the structure needs to have better energy dissipation capacity, but the final residual deformation of the structure must be very large

In order to reduce or even eliminate the damage and residual deformation of the structure while ensuring the energy dissipation capacity of the structure, many scholars have developed various cylinder damping structures from different angles. Capability is difficult to guarantee
