Abstract
The utility model relates to a tunable vibration absorbing device for pipelines of ship systems. The vibration absorbing device comprises a metal clamping ring; a hollow vibration absorbing ring is arranged in the metal clamping ring and spliced by sector-shaped vibration absorbing blocks closely attached to the inner wall of the metal clamping ring circumferentially; and each sector-shaped vibration absorbing block comprises an outer elastic component and an inner elastic component, a middle mass block is arranged between each outer elastic component and each inner elastic component, and the outer elastic component, the middle mass block and the inner elastic component are connected as a whole. During usage, the vibration absorbing device can block transmission routes of vibration when penetrated in the pipelines so as to achieve vibration absorption and isolation effects; when frequencies of flexural and longitudinal waves transmitting along the pipelines vary, the rigidity of the device is changed through loosening or tightening a bolt to change the most effective vibration abatement frequency range which is then changed to a high frequency or low frequency direction, so that the maximum vibration abatement effect is guaranteed in all obvious vibration components.
Description
Technical field
The utility model relates to pipeline noise reduction technology field, is specifically related to a kind of tunable pipeline shock-absorbing means of marine system pipeline.
Background technique
Pipeline vibration control is the important technical links of vibration reduction of ship noise reduction, but the vibration of establishment equipment and medium is by the transmission of pipeline.Existing ship pipeline vibration control gear generally adopts elastic support, comprises that the measures such as vibration isolator, sulfuration clamp ring, vibration isolator reduce pipeline vibration by the transmission of support zone to hull.Elastic support has is installing wide band vibration isolating effect on the Frequency point, but frequency range outstanding in the pipeline vibration do not possessed additional advantage, these outstanding frequency ranges can't realize effective vibration isolation and the vibration damping of pipeline vibration by still obviously outstanding after the isolation of elastic support.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of tunable pipeline shock-absorbing means for the deficiency that above-mentioned prior art exists, and it suppresses the outstanding frequency range in the pipeline vibration by tuning absorbing, realizes the maximum vibration isolating effect of pipeline vibration isolation.
The utility model is that the technological scheme that the problem of the above-mentioned proposition of solution adopts is: comprise the metal clamping ring, hollow absorbing ring is set in the metal clamping ring, described hollow absorbing ring is by being spliced along the fan-shaped absorber block of circumferentially being close to metal clamping ring inwall, described fan-shaped absorber block includes outer elastic element and interior elastic element, between inside and outside elastic element, be installed on the intermediate mass piece, and outer elastic element, intermediate mass piece and interior elastic element three are linked into one.
Press such scheme, described fan-shaped absorber block outer arced surface and metal clamping ring inwall phase configuration, intrados and pipeline external diameter phase configuration, fan-shaped absorber block bilateral symmetry arranges groove, makes its cross section be approximate T-shape.
Press such scheme, described hollow absorbing ring is spliced by the fan-shaped absorber block of even numbered blocks, and common fan-shaped absorber block is 4 ~ 8.
Press such scheme, the inside and outside elastic element of described fan-shaped absorber block is made by rubber, and the intermediate mass piece is slug, and three's sulfuration is integrated.
Press such scheme, described metal clamping ring consists of semicircular ring by two, and the joint of semicircular ring is arranged the lug of bending, and the lug place installs adjusting bolt and nut.
Press such scheme, described metal clamping ring and hollow absorbing annulate shaft are to isometric.
The beneficial effects of the utility model are: when 1, using it is threaded onto in the pipeline, when the bending that the vibration source excitation produces and extensional vibration are propagated along pipeline, arrive tunable pipeline shock-absorbing means, tunable pipeline shock-absorbing means is adjusted to the frequency of appointment, the impedance of its middle mass block has resilient characteristic and surpasses the unit mass impedance of pipeline at absolute value, hinder the propagation path of vibration, reached the absorbing vibration isolating effect to pipeline; 2, when the frequency change of the flexural wave of propagating along pipeline and longitudinal wave, by loosening or tight a bolt the rigidity of modifier, change its most effective vibration suppression frequency range, it is moved on to high frequency or low frequency direction, to guarantee at all the most obvious oscillating components maximum inhibition of vibration being arranged.
