The invention overcomes the defects of the prior art and provides the vibration absorber which can meet the operating environment requirements of a product needing both vibration damping and heat dissipation; the vibration absorber is especially suitable for the vibration damping of the small-scale articles with high accuracy requirements such as rubidium clocks, etc.
Description
Technical field
The present invention relates to a kind of vibration damping equipment, be particularly useful for that rubidium clock etc. is small-sized, the vibration damping of high-precision requirement object.
Background technique
Along with improving constantly of science and technology, in the contour dynamic carrier of automobile, aircraft and guided missile, need to use rubidium clock that the temporal frequency benchmark of low aging, high accuracy and stability is provided.But because the structure of rubidium clock itself is relatively more accurate, the circuit more complicated, the influence that output frequency is vibrated is bigger, therefore how to improve the anti-vibration performance of rubidium clock, and the effect of rubidium clock in high dynamic environment played conclusive effect.In order to improve the anti-vibration performance of rubidium clock, except carrying out reasonable structural design (mainly being the form structure, mounting point, means of fixation etc. of quantum physics part), data from every side, all mentioned the increase vibration damping to reduce the dither magnitude, concrete oscillation damping method, measure have not still all been arranged.
Vibration damper (a kind of vibration damping equipment) is generally adopted in Vibration Absorption Designing on the star at present, and is comparatively suitable at the vibration damping object that volume is bigger; For little module of volume (crystal oscillator module) or printed board (answering machine crystal oscillation circuit plate) vibration damping, then adopt the outer wrap damping materials or clog method such as vibration damping silicone rubber pad all around.Above-mentioned vibration damping object is compared with small-sized rubidium clock, the general less problem that does not have heat radiation of power consumption, so all do not consider the heat radiation requirement in these Vibration Absorption Designings.And rubidium clock 124 ml volumes sizes only, start power consumption 18W, the stable power consumption normal temperature under is 7 watts, if do not consider heat radiation, temperature range that will its proper functioning of shortening.
Summary of the invention
Technology of the present invention is dealt with problems and is: overcome the deficiencies in the prior art, the vibration damping equipment that provides a kind of working environment that is fit to the product that not only needs vibration damping but also needs dispel the heat to require.
Technical solution of the present invention is: a kind of vibration damping equipment, comprise one with the box body for the treatment of vibration damping body form coupling, inlay or paste damping material on this box side wall and the top blind flange, damping ring is installed in the box body bottom, uniform winding heat sink material on the damping ring, the described vibration damping object for the treatment of is placed on the damping ring; Wherein, described heat sink material preparation process is as follows:
At first, take out inner core, obtain the external shield wire netting shielding wire;
Then the external shield wire netting flattened, promptly obtain heat sink material by the segment shortening.
Also comprise liner plate, liner plate with treat to be placed on the damping ring after the vibration damping object is fixed together.
Described by the segment shortening, shorten back length and be controlled at 45%～54% of external shield wire netting pressing back length.
Described damping material adopts silicone rubber.
Described damping ring adopts the silicone rubber post, or silicon rubber loop.
The present invention compared with prior art beneficial effect is:
(1) the present invention improves the anti-seismic performance of complete machine by mechanical vibration damping, by adopting the heat conduction damping ring, and strengthen model machine and external heat conduction by the self-control heat sink material, increase and to treat the heat dissipation potential of vibration damping object and bottom box body, thereby satisfy the working environment requirement of the product that this not only needs vibration damping of similar rubidium clock but also needs dispel the heat.
(2) heat sink material of the present invention adopts the outer wire netting of shielding wire commonly used to make, this heat sink material radiating effect is good, and this heat sink material is netted flexible structure, can not increase the rigidity of whole system, therefore when satisfying the heat radiation requirement, can cooperate the vibration isolation rubber material to reach the favorable damping performance.
(3) damping material of the present invention etc. is selected the space industry versatile material for use, and it is convenient to implement, the lighter weight of vibration damping part, and damping property is easy to regulate.

Embodiment
Be example with the rubidium clock below, introduce apparatus of the present invention in detail.
Shown in Fig. 1～4,1 is the vibration damping box body; 2 is the vibration isolation rubber post; 3 is vibration damping box body head cover plate; 4 is heat sink material; 5 is the vibration isolation rubber circle.
Rubidium clock is fixed on the liner plate effect of this liner plate by 4 screws: one side relative fixed product space increases heat diffusion area on the other hand; Embedding 8 silicone rubber posts around box body 1 on the sidewall, according to the size for the treatment of damping body, is 1mm apart from the gap generally, rubber column length with treat that the damping body height is consistent.Embed 4 silicone rubber pads on box body head cover plate 3, the rubber pad height should guarantee that rubber pad contacts no gap with treating damping body under the situation that does not have distortion; In the box body bottom, place a silicon rubber loop,
The damping ring external diameter is generally being treated in the damping body bottom surface, helps as far as possible greatly like this guaranteeing to treat that damping body is steady; Heat sink material around the home uniformly on damping ring is determined the number of turns according to temperature and vibration test, is 0.216kg as the weight of damping body, and the cross-sectional diameter of damping ring is 5mm, and the damping ring internal diameter is 66mm, and shore hardness is the silicone rubber of 22 degree.The number of turns that heat sink material twines is 15 circles, and writhing number is relatively poor greater than 15 number of turns vibration dampings, and writhing number is bad less than the heat radiation of 15 number of turns, therefore selects for use and twines 15 circles, after winding two ends is welded together.Cover head cover plate, fastening by screw all around.According to the actual vibration test requirements document, if will be on original vibration damping basis further vibration damping, damping ring can be made hollow, to satisfy further vibration damping requirement.
Heat sink material is to adopt used shielding wire (title: ART-100 usually, model: 19 * 0.1) self-control forms, its working process is: with shielding wire, after taking out inner core, the external shield wire netting is flattened, shortens by segment by hand, generally shorten to the external shield wire netting and flatten about half of back length, for example former being about is 125mm, is about 62mm after the shortening.
By above-mentioned cooling measure, the operating temperature range of model machine can reach-40-+75 ℃.
The sinusoidal initial conditions of vibration test is seen Fig. 5, and random vibration condition is: the total root mean square acceleration of 10～2000Hz is 5.5grms:
Table 1
Table 1 is different vibration damping scheme comparison of test results results.As can be seen from the table, the effectiveness in vibration suppression of 15 circles is best, has solved heat dissipation problem simultaneously, and has satisfied requirement on electric performance.
Test by experiment, vibration reducing measure are effectively, have been reduced to 2-3g from the 5g magnitude of importing.
The unspecified part of the present invention belongs to general knowledge as well known to those skilled in the art.
