Embodiment Construction

[0029] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0030] This embodiment discloses a vertically tuned mass damper, such as figure 1 As shown, it includes a guide rod 1, a mass block 2 and an elastic member 3, the guide rod 1 is vertically arranged, and the mass block 2 is slidably sleeved on the guide rod 1; the fixing of the elastic member 3 The end is relatively fixed to the main structure A, and the free end is connected to the mass block 2 . The elastic member 3 must be kept within its deformability range, that is, the elastic member 3 can be subjected to the interaction between the mass block 2 and the main structure A to produce an appropri...

Abstract

The invention belongs to the technical field of structure vibration reduction, and particularly relates to a vertical tuning mass damper. The damper comprises a guide rod, a mass block and an elasticpart, the guide rod is vertically arranged, and the mass block slidingly sleeves the guide rod; a fixed end of the elastic part is relatively fixed to a main structure body, and a free end is connected with the mass block. The vertical tuning mass damper aims at solving the problem that an existing vertical tuning mass damper is not good in vibration reduction effect. The mass block of the vertical tuning mass damper is not twisted in the vertical direction, and the vertical vibration effect of a control mode is better. According to the vertical tuning mass damper, the guide rod is verticallyarranged, the movement direction of the mass block is limited in the vertical direction, and torsional vibration of the damper is prevented, so that the vertical vibration prevention effect of the main structure body such as bridges is more remarkable.

Description

technical field [0001] The invention belongs to the technical field of structural vibration reduction, and in particular relates to a vertically tuned mass damper. Background technique [0002] Tuned mass dampers are widely used in civil and mechanical fields to control low-frequency vibrations of structures; such as the resonance of pedestrian bridges under pedestrian loads, the vibration of large aspect ratio structures under wind loads, and wind-induced vortex vibrations of bridges and cylindrical structures Wait. Both theory and practice have proved that tuned mass dampers have a good suppression effect on vibrations with excellent frequencies. In particular, with the continuous advancement of science and technology in structural calculation, construction technology and building materials, the span of bridges is getting larger and larger, so higher requirements are placed on the anti-vibration performance of bridges. [0003] For the case of controlling the unidirectio...
