Abstract

The invention provides a spherical surface TMD (Turning Mass Damper) shock absorption control device, which comprises a bottom plate component and a mass block component glidingly matched with the bottom plate component, wherein the weight of the mass block component is m; the top of the bottom plate component is provided with N concave spherical surfaces; the bottom of the mass block component is provided with N convex spherical surfaces glidingly matched with the concave spherical surfaces; the concave spherical surfaces and the convex spherical surfaces have the identical spherical surface radius R; a sliding friction pair is arranged between the convex spherical surfaces and the concave spherical surfaces; and a damping device is arranged between the mass block component and the bottom plate component. The spherical surface TMD shock absorption control device has the advantages that the additional damping can be increased through setting different friction factors; meanwhile, through a single pendulum simple harmonic moving principle, an elastic element of a traditional TMD is replaced; the design is scientific; the structure is compact; the operation and the use are convenient; the problems that for the existing TMD technology, the manufacturing cost is high, a greater installation space is needed, a structural element can be easily damaged, and the like can be solved; and the spherical surface TMD shock absorption control device is particularly applicable to the control of low-frequency vibration of a structure.

Description

Technical field [0001] The invention relates to a bridge vibration reduction and isolation control device, in particular to a spherical tuned mass damper vibration reduction control device. Background technique [0002] With the development of civil engineering, the aspect ratio of high-rise building structures has become larger and larger, and the span of bridge structures has also been increasing. As a result, the structure is relatively softer and softer, and the natural vibration frequency of the structure is decreasing. Under the external effects of strong winds, earthquakes, vehicle dynamics, crowds, etc., the structure can easily cause vibration or shaking. Relying on traditional methods to improve the rigidity of the structure is unreasonable from an economic and aesthetic point of view. The bearing capacity can meet the requirements, but the vibration of the structure will cause hazards such as certain parts of the structure, fatigue damage and even fracture of the weld ...
