Problems solved by technology

Since the tuned mass damper mostly adopts the suspension structure using gravity characteristics, it can be used for the vertical vibration suppression of horizontal pipelines, but it is difficult to apply to the horizontal vibration of existing pipelines and the vertical vibration suppression of vertical pipelines

Embodiment Construction

[0019] The present invention will be further described below in conjunction with the drawings and embodiments.

[0020] Such as figure 1 , figure 2 As shown, the present invention includes a whole outer ring 1, a whole inner ring 2, a plurality of springs 7 and the same number of dampers 8 as the springs 7; the whole outer ring 1 is a split structure consisting of two identical and symmetrical half outer rings Ring 3 uses two screws 4 to form a complete outer ring 1; the whole inner ring 2 is also a split structure, and two identical and symmetrical half inner rings 5 ​​are used to form a complete outer ring 2 with the other two screws 6; A combination of four springs and four dampers are installed symmetrically between the outer ring 1 and the entire inner ring 2 in the circumferential direction. The entire outer ring 1 and the entire inner ring 2 form a complete tuned mass damper 11 through multiple sets of springs 7 and dampers 8.

[0021] The inner diameter of the integral in...

Abstract

The invention discloses a tuned mass damper structure for reducing pipeline vibration. In the invention, an entire outer ring is in a dividable structure and is formed by combining two identical and symmetrical half outer rings by using two bolts; an entire inner ring is also in a dividable structure and is formed by combining two identical and symmetrical half inner rings by using another two bolts; a plurality of springs and dampers having the same number with the springs are circumferentially and symmetrically arranged between the entire outer ring and the entire inner ring, thus the supporting rigidities and the damping performances of the outer ring in all directions of the circumference are same; and the inner diameter of the entire inner ring is smaller than the outer diameter of a clamped damping pipeline. When the vibration of the traditional pipeline is needed to be reduced, the rigidity of the springs and the damping of the dampers are calculated as actually required, and then a manufactured tuned mass damper is fixed on the pipeline on the spot, thus a required damping effect can be obtained. The damper is in a dividable structure and has the advantages of simple structure, high reliability and easiness for realization.

Description

Technical field [0001] The invention relates to a tuned mass damper structure, in particular to a tuned mass damper structure for reducing pipeline vibration. Background technique [0002] The research on vibration system control has become one of the hot spots in the field of engineering machinery research today. According to the need to absorb energy from the outside, the control of the vibration system is divided into active control and passive control. Theoretically, active control is better than passive control, but due to the theoretical and practical engineering conditions, the installation of active control system in the structure requires modification of the structural design and is difficult to implement. At present, passive control systems are the most widely used and relatively mature in engineering. [0003] The same is true for the vibration control of the pipeline system. There are many difficulties in the actual implementation of the pipeline vibration active cont...
