Description
Technical field
The utility model belongs to the technical field that pipe vibration noise is effectively controlled, and formed three-dimensional pipeline dynamic vibration absorber, the pipeline vibration-absorbing denoising technological method particularly by wire rope, pipeline being connected with associated mass and formation can be to pipeline axial, radially and the vibration of three directions reversing around the axis three-dimensional pipeline dynamic vibration absorber that control effectively and absorb.
Background technique
Pipeline is widely used in various commercial plants and living facilities, and a large amount of pipeline ubiquities that use vibrate the problems large, noise is high both at home and abroad at present.A lot of about pipe vibration noise problem researcher, its method probably can be divided into two classes.One class is to start with from pipeline configuration, material, adopts elasticity pipeline section, with absorbing, damping material, makes tube wall and in pipeline, adds (the Kong Jianyi etc. such as pulsation dampening, the control research of submarine vibration noise, noise and vibration control, 2006,26 (5)).Such measures need to be considered the impact that it produces pipeline inner fluid, implements more complicated and expense is higher, is difficult for popularizing.Another kind of is dynamic absorber technology, by add dynamic vibration absorber outward at tube wall, controls pipe vibration (Liu Yaozong etc., passive type dynamic absorber Research progress, mechanical engineering journal, 2007,43 (3); State of Zhao moves etc., the research of the complete initiatively absorbing technology experiment of Diesel Piping System, noise and vibration control, 2007,27 (5)).Dynamic vibration absorber can be used as subtense angle and is attached directly in main pipe system, and be not subject to that pipeline is high temperature resistant, restriction that high pressure and anti-leak etc. require.Whether according to it, need the external world that energy is provided, that dynamic vibration absorber can be divided into is active, passive type etc.Owing to there is the unfavorable features such as guarantee that complex structure, manufacture cost are high, need outside resources, active bump leveller has very large narrow limitation in actual applications.Passive type bump leveller is the main flow of engineering application, and correlative study has also obtained many new developments.Wherein multi-freedom degree dynamic vibration absorber can reduce associated mass, but improves the efficiency of shaking, and makes the compacter practicality of structure of bump leveller, therefore becomes the important developing direction of dynamic absorber technology and study hotspot.
Summary of the invention
The utility model is exactly the problem for the Noise and Vibration Control existence of above-mentioned pipeline, a kind of three-dimensional pipeline dynamic vibration absorber that pipe vibration noise is control effectively and pipe vibration noise control method thereof are provided, three-dimensional pipeline dynamic vibration absorber is comprised of associated mass ring, wire rope, retaining ring, connecting bolt, pipeline and screw, wherein associated mass ring is comprised of main ring and regulating ring, can be along any direction free vibration, wherein regulating ring is to finely tune for quality.Retaining ring is tightly placed on pipeline outer wall, retaining ring and uniform six circular ports of opposite position above associated mass ring, and wire rope inserts in circular port, and its two ends are connected with associated mass ring with retaining ring respectively by screw.Retaining ring and associated mass ring are all designed to the form of two semicircular ring docking, and utilizing connecting bolt is an annulus by two semi-ring docking, to facilitate installation.
As the wire rope quantity of elastic element, be at least 3 and be arranged symmetrically with, to guarantee that radial rigidity is symmetrical, must be consistent with radial rigidity by regulating wire rope axial length to realize axial rigidity; Outer surface sulfuration one deck rubber layer of wire rope, to increase the damping of bump leveller, and then increases absorbing frequency bandwidth, to adapt to the fluctuation of pipe vibration frequency.
Compared with the prior art, tool has the following advantages the utility model:
(1) utilize elasticity and the damping characteristic of wire rope, can to pipeline axial, radially and the vibration of three directions reversing around axis controlled and absorbed, can obtain and fall low noise effect simultaneously;
(2) overcome the measure that need to change pipeline configuration and material and implement the shortcoming complicated, expense is higher, can be made into the form of two semicircular ring docking, easy to use, and be not subject to that pipeline is high pressure resistant, restriction that anti-leak etc. requires;
(3) adopt passive type dynamic absorber principle design, overcome the shortcomings such as guarantee that active power bump leveller complex structure, manufacture cost are high, need outside resources.

Embodiment
Example below in conjunction with accompanying drawing further illustrates.Three-dimensional pipeline dynamic vibration absorber of the present utility model is comprised of associated mass ring, wire rope 2, retaining ring 3, connecting bolt 4 and screw 6, and in figure, 5 is pipeline.Wherein associated mass ring is comprised of main ring 1 and regulating ring 7, can be along any direction free vibration, and wherein regulating ring 7 is finely tuned for quality.Retaining ring 3 is tightly placed on the outer wall of pipeline 5, retaining ring 3 and uniform six circular ports above associated mass ring, and wire rope 2 inserts in these holes, and its two ends are connected with associated mass ring with retaining ring 3 respectively by screw 6.Retaining ring 3 and associated mass ring are all designed to the form of two semicircular ring docking, and can utilize connecting bolt 4 is an annulus by two semi-ring docking, to facilitate installation.As the wire rope quantity of elastic element, be at least 3 and be arranged symmetrically with, to guarantee that radial rigidity is symmetrical, must be consistent with radial rigidity by regulating wire rope axial length to realize axial rigidity; Outer surface sulfuration one deck rubber layer 8 of wire rope, to increase the damping of bump leveller, and then increases absorbing frequency bandwidth, to adapt to the fluctuation of pipe vibration frequency.This dynamic vibration absorber can be transferred to the vibrational energy of pipeline 5 on associated mass ring, and utilizes the damping characteristic of wire rope 2 that vibrational energy is consumed gradually, sponged.By rational structure and parameters is set, if length, rigidity, sth. made by twisting by controlling wire rope 2 are to regulating its elasticity and damping characteristic with the parameter such as bending part curvature, by controlling the parameters such as density, internal-and external diameter length of associated mass ring, regulate its size and quality size etc., can to pipeline axial, radially and the vibration of three directions reversing around axis controlled and absorbed, can obtain and fall low noise effect simultaneously.
