Abstract
The utility model discloses a tuned mass damper structure for reducing pipe vibration. A whole outer ring is a divisible structure and formed by combining two identical and symmetrical half outer rings through two screws. A whole inner ring is a divisible structure and formed by combining two identical and symmetrical half inner rings through another two screws. A plurality of springs and dampers which are the same as the springs in number are circumferentially and symmetrically arranged between the whole outer ring and the whole inner ring to enable supporting rigidity of the outer ring and the dampers to be circumferentially isotropic. The inner diameter of the whole inner ring is smaller than the outer diameter of a clamped vibration-reducing pipe. When the vibration of a ready-made pipe is reduced, required rigidity of the springs and required damping of the dampers are obtained according to actual requirements by calculating, and then a manufactured tuned mass damper is fixed on an on-site pipe, thereby obtaining required vibration-reducing effect. The tuned mass damper structure for reducing the pipe vibration adopts the divisible structures and is simple in structure, high in reliability and easy to realize.
Description
Technical field
The utility model relates to a kind of tuned mass damper structure, especially relates to a kind of tuned mass damper structure that reduces pipe vibration.
Background technique
Research to vibration system control has become one of focus of current engineering machinery research field.According to whether needs absorb energy from the external world, the control of vibration system is divided into ACTIVE CONTROL and Passive Control.Theoretically, ACTIVE CONTROL is better than Passive Control, but owing in theory with reason such as engineering physical condition restriction, the installation of ACTIVE CONTROL system in structure need be revised structural design and be difficult to carry out.Use maximum, the most ripe relatively still passive control system at present on the engineering.
The vibration control of pipe-line system also is that so there are many difficulties in pipe vibration ACTIVE CONTROL method in the enforcement of reality, and by contrast, vibration passive control has more the possibility of enforcement.Tend in the general Passive Control that pipeline is added support and increase damping and support stiffness.But for the pipeline of many ready-made vibrations, can't handle the underlying issue of support, promptly many occasions can't support on-the-spot directly the increasing of pipeline, even perhaps increase support, expense is also than higher.In order to address this problem, can adopt tuned mass damper to come pipeline is carried out vibration damping.
Tuned mass damper is a vibration system of being made up of spring, damper and mass block, and its theoretical research is very ripe.The general suspension of tuned mass damper structurally, the mechanism of structure being carried out vibration control is: when structure produces vibration under the incentive action outside, driving the tuned mass damper system vibrates together, the inertial force that the tuned mass damper system produces reacts on the structure, tuning this inertial force, make its vibration produce tunning effect, thereby reach the purpose that reduces the structural vibration reaction main structure.Because the tuned mass damper suspension structuress of utilizing the gravity characteristic that adopt, the vertical vibration that can be used for horizontal pipe suppresses more, but is difficult to be applied to the vibration suppression of the Vertical direction of the vibration of substantially horizontal of existing pipeline and vertical pipe.
Summary of the invention
The purpose of this utility model is to provide a kind of tuned mass damper structure that reduces pipe vibration, be a kind of simple, be easy to realize, reliability is high, the tuned mass damper structure of can fine reduction ready-made Analysis of Pipe Vibrations.
In order to reach above-mentioned purpose, the technical solution adopted in the utility model is:
The utility model comprises whole outer shroud, whole interior ring, a plurality of spring and the damper identical with number springs; But whole outer shroud is the subdivision structure, synthesizes whole outer shroud by two half identical and symmetrical outer shrouds with two screws; But encircling in whole also is the subdivision structure, encircles in being put in order with two other screw is synthetic by two half identical and symmetrical interior rings; Whole outer shroud and whole in circumferential symmetry installation a plurality of springs and the damper identical between the ring with number springs, make the support stiffness of outer shroud and damping in circumferential isotropy.
The internal diameter of described whole interior ring is less than the external diameter that is held the vibration damping pipeline
Compare with the device of the ready-made pipe vibration of existing reduction, advantage of the present utility model is:
1) adopted the subdivision structure, simple in structure, the reliability height is easy to realize;
2) when reducing ready-made Analysis of Pipe Vibrations, require to calculate the rigidity of required spring and the damping of damper according to reality, just can obtain the effectiveness in vibration suppression that needs on the pipeline at the scene of then tuned mass damper of making being fixed on;
3) applied widely.Need the piping of vibration damping for the scene, after can adopting finite element to carry out system optimization to calculate, in different oscillating points different tuned mass dampers is set and gets final product.
