Abstract
The utility model belongs to the technical field of vibration dampers and relates to a vibration damping device with a vibration damping function arranged in a vessel housing and used for measuring self noise of the hydrophone. The vibration damper comprises a metal base welded with the vessel housing, a T-shaped vibration damping rubber block and metal clamps. The T-shaped vibration damping rubber block is fixed on the base via a bolt. The metal clamps are fixed on the vibration damping rubber block via blots. The vibration damper is characterized in that: the T-shaped vibration damping rubber block is connected with the vessel housing; housing vibration of a T-shaped vibration damping rubber block is changed by a longitudinal-transverse-longitudinal transmission mode so that vibration is largely attenuated; the vibration damping rubber block is T-shaped and the material of vibration damping rubber block is chloroprene rubber of Shore 60 DEG plus or minus 5 DEG in hardness. The vibration damper for the hydrophone has following beneficial effects: measurement of the hydrophone is less affected by the housing vibration so that measured data about water noise is accurate and reliable; and the vibration damper can be broadly applied to ships, submarines, underwater machinery equipment and other vibration dampers for hydrophones used for measuring and monitoring with requirements for vibration damping.
Description
Technical field
The invention belongs to damper technique field, relate to the vibration damping equipment that a kind of hydrophorce of measuring self noise to being installed on naval vessels housing plays damping effect.
Background technique
In the measurement of naval vessels self noise, hydrophorce is installed on the housing of naval vessels underwater portion, obtains naval vessels self water noise signal.Because the vibration of naval vessels housing can cause the electrical signal output of hydrophorce equally, therefore be to reduce the impact that hull vibration is measured naval vessels self water noise, reply measurement hydrophone is carried out vibration damping installation, and the effect of vibration damping is better, and the data of measurement are more accurate.Currently used oscillation damping method is between the fixture of fixed hydrophone, to pad the rubber plate of one deck 3mm.Because of the soundness requirement that hydrophorce is installed, fixture is very tight, and rubber plate has not had effectiveness in vibration suppression, in measurement result, must mix the composition that has hull vibration, and measurement accuracy is had to impact.
Summary of the invention
The object of this invention is to provide a kind of hydrophorce vibration damping equipment with effectiveness in vibration suppression.This damping device is in order to solve the problem that affects measurement accuracy because of effectiveness in vibration suppression.
Technological scheme of the present invention is,
A vibration damper, this hydrophorce vibration damper comprises metallic base, T shape damping rubber block and metal fixture; Metallic base is welded on naval vessels housing; T shape damping rubber block is bolted on metallic base; Metal fixture is bolted on damping rubber block.
First base is welded on naval vessels housing, by bolt, T shape damping rubber block is fixed on base.Between metal fixture and hydrophorce, pad after the rubber plate of one deck 3mm, then with two or four bolts, hydrophorce fixture is fixed on T shape damping rubber block.This vibration damper, makes to exist one to have certain thickness damping rubber block between hydrophorce fixture and naval vessels housing.Naval vessels hull vibration through the change of vertical-horizontal-vertical circulation way, makes vibration obtain a large amount of decay in T shape damping rubber block block rubber.When selecting rubber hardness 60 ° ± 5 ° of Shao Er, can there is obvious effectiveness in vibration suppression, can meet the installation soundness requirement of hydrophorce simultaneously.Adopt neoprene as vibration isolation rubber block of material, can sea water resistance long period of soaking, adapt to long-term work under water.
Effect of the present invention and benefit be, can make naval vessels self noise hydrophorce reduce the impact of hull vibration, and the data that water noise is measured more accurately and reliably, and can adapt to long-term stable operation in seawater.The present invention is widely used in to vibration damping, having the hydrophorce vibration damping of requirement to install in boats and ships, submarine, submarine mechanical equipment and other subaqueous survey.

Fig. 1 is the hydrophorce scheme of installation of prior art.
Fig. 2 is the side view of Fig. 1.
Fig. 3 is hydrophorce damper combination scheme of installation of the present invention.
Fig. 4 is the side view of Fig. 3.
In figure: 1 rubber plate, 2 hydrophorces, 3 fixture bolts, 4 metal fixtures, 5T shape damping rubber block, 6 block rubber bolts, 7 bases, 8 naval vessels housings.
Embodiment
Below in conjunction with technological scheme and accompanying drawing, describe the specific embodiment of the present invention in detail.
The specific embodiment of the present invention is as follows: with reference to Fig. 3, first base 7 is welded on naval vessels housing 8, by block rubber bolt 6 adapted spring pads and pad, T shape damping rubber block 5 is fixed on base 7.Again hydrophorce 2 is wound around to one deck 3mm rubber plate 1, with fixture 4, hydrophorce 2 is clamped, by fixture bolt 3 adapted nuts, spring pad and pad, fixture 4 is fixed on T shape damping rubber block 5.First hull vibration is delivered on block rubber by block rubber bolt 6 with compressional wave form, two shoulders by T shape damping rubber block 5 are transmitted to fixture bolt 3 again, because the form at two shoulder places changes, compressional wave becomes shear wave, finally by fixture bolt 3, with the form of compressional wave, is passed to hydrophorce again.Hull vibration through the change of vertical-horizontal-vertical circulation way, makes vibration obtain a large amount of decay in block rubber, makes hydrophorce greatly reduced by the impact of hull vibration.The rubber hardness of having selected in this example 62 ° of Shao Er, has produced obvious effectiveness in vibration suppression, and can meet the installation soundness requirement of hydrophorce.The vibration isolation rubber block of material adopting is in this example neoprene, has the performance of sea water resistance long period of soaking, can adapt to long-term work under water.
