[detailed description of the invention]

Referring to shown in Figure of description 1 to accompanying drawing 18, the present invention filters for one full frequency band structure changes, magnetize, inhales Echoing centrifugal Rose Box, it is by base plate 6, wave filter 8, U-shaped separation of particles module 3, oil returning tube 7, inner core 15, helical flow path 17, several parts such as filter core 18, outer barrel 19 and end cap 25 composition.Wherein, described wave filter 8, U-shaped separation of particles module 2, oil return Cylinder 7, outer barrel 19 are sequentially placed on base plate 6.

Described wave filter 8 is for inputting hydraulic oil, and the pulsation pressure of the high, medium and low frequency range that can decay in hydraulic system Power, and suppression flowed fluctuation.Described wave filter 8 is by input pipe 81, shell 88, efferent duct 89, S type elastic thin-wall 87, the filtering of H type Several parts compositions such as device 812 and cascaded H mode filter 813.

Wherein, described input pipe 81 is connected to one end of shell 89, and itself and a hydraulic oil inlet 1 are docked；Described efferent duct 811 other ends being connected to shell 89, itself and U-shaped separation of particles module 3 are docked.Described S type elastic thin-wall 87 is along the footpath of shell In being installed on shell 88, in it, form expansion chamber 71 and contraction chamber 72.The axis of described input pipe 81 and efferent duct 89 does not exists On same axis, so can improve the filter effect of more than 10%.

Described input pipe 81, efferent duct 89 and S type elastic thin-wall 87 are collectively forming a S type cavity volume wave filter, thus decay Hydraulic system high frequency pressure pulsations.The filter transmission coefficient obtained after processing by lumped-parameter method is:

$\mathrm{\γ}=\frac{1}{1+{(\frac{2\mathrm{\π}f}{Z}\·\frac{\frac{2}{3}{k}_1{D}^3+k_2{d}^{2}L}{{d_I}^2\·a})}^2}$

Velocity of sound L contraction chamber length D expansion chamber diameter Z characteristic impedance in a medium

γ transmission coefficient f pressure oscillation frequency d_IInput pipe diameter d contraction chamber diameter

k₁Expansion chamber coefficient k₂Contraction chamber coefficient

From above formula, S type cavity volume wave filter is similar with the electric capacity effect in circuit.The pressure pulse wave of different frequency leads to When crossing this wave filter, transmission coefficient is different with frequency.Frequency is the highest, then transmission coefficient is the least, and this shows the pressure arteries and veins of high frequency Dynamic ripple is decayed the most severe when device after filtering, thus serves the effect eliminating high frequency pressure pulsations.Meanwhile, the present invention In S type holding cavity structure, transitions smooth between expansion chamber and contraction chamber, contribute to reducing the system pressure that cavity diameter sudden change brings Loss.The input pipe of wave filter and efferent duct the most on the same axis, can improve the filter effect of more than 10%.

The design principle of described S type cavity volume wave filter is as follows: when the flow of change enters the swollen of S type cavity volume by input pipe During swollen chamber, liquid flow exceedes average discharge, and the expansion chamber of expansion can absorb unnecessary liquid flow, and releases liquid when less than average discharge Stream, thus absorption pressure pulsation energy.The combination of multiple expansion chamber and contraction chamber then improves the fluctuation pressure of wave filter and absorbs Ability, namely filtering performance.Use curved surface to smoothly transit between expansion chamber and contraction chamber, then avoid by fluid boundary sudden change band That comes loses along stroke pressure and heating.

Described S type elastic thin-wall 87 weakens hydraulic system medium-high frequency pressure fluctuation by being forced to mechanical oscillation.By lump The S type elastic thin-wall intrinsic frequency that parametric method obtains after processing is:

$f_m=\frac{k^{2}h}{2{\mathrm{\πR}}^2}\·\sqrt{\frac{E}{12\mathrm{\ρ}(1+\mathrm{\η})(1-{\mathrm{\μ}}^2)}}$

K S type elastic thin-walled structures coefficient h S type elastic thin-wall thickness R S type elastic thin-wall radius

The mass density of the Young's modulus ρ S type elastic thin-wall of E S type elastic thin-wall

The Poisson's ratio of the current-carrying factor mu S type elastic thin-wall of η S type elastic thin-wall.

Substitute into actual parameter, above formula is carried out simulation analysis it is found that S type elastic thin-wall 87 intrinsic frequency generally than The intrinsic frequency of H mode filter is high, and its attenuation band is also wide than H mode filter.In relatively wide frequency band range, S Type elastic thin-wall has good attenuating to pressure fluctuation.Meanwhile, the S type elastic thin-wall in the filter construction of the present invention Radius is bigger and relatively thin, and its intrinsic frequency, closer to Mid Frequency, can realize having the medium-high frequency pressure fluctuation in hydraulic system Effect decay.

The design principle of described S type elastic thin-wall 87 is as follows: when producing intermediate frequency pressure fluctuation in pipeline, S type cavity volume is to pressure The damping capacity of fluctuation is more weak, flows into the periodically pulsing pressure continuous action of wave filter S type cavity volume at S type elastic thin-wall 87 Inside and outside wall on, owing to having between inside and outside wall, pillar is fixing to be connected, and inside and outside elastic thin-wall does week by the frequency of fluctuation pressure simultaneously Phase property is vibrated, and this forced vibration consumes the pressure fluctuation energy of fluid, thus realizes the filtering of Mid Frequency pressure.By the principle of virtual work Understanding, elastic thin-wall consumes ability and potential energy during its forced vibration and the direct phase of kinetic energy sum of fluid pulsation pressure energy Closing, in order to improve Mid Frequency filtering performance, the radial design of elastic thin-wall is much larger than pipe radius, and the thickness of thin-walled is relatively Little, representative value is less than 0.1mm.

Further, resonance series cavity volume I84 and parallel resonance are formed between described S type elastic thin-wall 87 and shell 88 Cavity volume 85.The outside of described resonance series cavity volume I84 sets a resonance series cavity volume II83, described resonance series cavity volume I84 and string Allying the communists shakes is connected by a taper insertion pipe 82 between cavity volume II83, and described taper is inserted the wider place of pipe 82 opening and is positioned at series connection altogether Shaking in cavity volume II83, its taper angle is 10 °.The resistance of some taper structure changes is uniformly had in the axial direction of described S type elastic thin-wall 87 Buddhist nun hole 86.

Described H mode filter 812 is positioned at parallel resonance cavity volume 85, and it is connected with taper structure changes damping hole 86.Institute State the wider place of taper structure changes damping hole 86 opening and be positioned at resonance series cavity volume I84 and parallel resonance cavity volume 85, its taper angle It it is 10 °.The wave filter natural angular frequency obtained after processing by lumped-parameter method is:

Described cascaded H mode filter 813 is positioned at resonance series cavity volume I84 and resonance series cavity volume II83, and it also and is bored Deformation structure damping hole 86 is connected.After processing by lumped-parameter method, two natural angular frequencies of cascaded H mode filter 813 are:

${\mathrm{\ω}}_1=\frac{\sqrt{\mathrm{\π}}a}{\sqrt{2}\sqrt{{\frac{{\mathrm{\πl}}_1({d_2}^2{l}_2+{d_4}^2{l}_4)}{4{d_1}^2}}_1+\frac{{{\mathrm{\πd}}_4}^2{l}_4{l}_3}{4{d_3}^2}+\sqrt{{\[{\frac{{\mathrm{\πl}}_1({d_2}^2{l}_2+{d_4}^2{l}_4)}{4{d_1}^2}}_1-\frac{{{\mathrm{\πd}}_4}^2{l}_4{l}_3}{4{d_3}^2}\]}^2+\frac{{\mathrm{\π}}^2{d_4}^4{l_4}^2{l}_1{l}_3}{4d_1^2{d}_3^2}}}}$

${\mathrm{\ω}}_2=\frac{\sqrt{\mathrm{\π}}a}{\sqrt{2}\sqrt{{\frac{{\mathrm{\πl}}_1({d_2}^2{l}_2+{d_4}^2{l}_4)}{4{d_1}^2}}_1+\frac{{{\mathrm{\πd}}_4}^2{l}_4{l}_3}{4{d_3}^2}-\sqrt{{\[{\frac{{\mathrm{\πl}}_1({d_2}^2{l}_2+{d_4}^2{l}_4)}{4{d_1}^2}}_1-\frac{{{\mathrm{\πd}}_4}^2{l}_4{l}_3}{4{d_3}^2}\]}^2+\frac{{\mathrm{\π}}^2{d_4}^4{l_4}^2{l}_1{l}_3}{4d_1^2{d}_3^2}}}}$

Described H mode filter 812 and cascaded H mode filter 813 are axially symmetrical set, and form the filtering of connection in series-parallel H type Device, for broadening frequency filtering scope and make overall structure more compact.The multiple connection in series-parallel H types of the present invention circumferentially interface distributions Wave filter (only depicts 2) in figure, separate with dividing plate 820 each other, and the resonance bands of these multiple wave filters is different, Whole medium and low frequency filtering frequency range can be covered, it is achieved the entire spectrum filtering of medium and low frequency section after combining comprehensively.

All can be found by Fig. 6 H mode filter and cascaded H mode filter frequency characteristic and formula, cascaded H mode filter has 2 Individual natural angular frequency, at crest, filter effect is preferable, does not the most substantially have filter effect at trough；H mode filter has 1 Natural angular frequency, at crest, filter effect is preferable equally, does not the most substantially have filter effect at trough；Select suitably filter Ripple device parameter, makes the natural angular frequency of H mode filter just fall between 2 natural angular frequencies of cascaded H mode filter, such as figure Shown in 7, in certain frequency range, both defined the natural reonant frequency peak value of 3 next-door neighbours, in this frequency range, no matter The fluctuating frequency of pressure is at crest or all can guarantee that preferable filter effect at trough.Multiple connection in series-parallel H mode filter structures The bank of filters become both can cover whole medium and low frequency section, it is achieved the entire spectrum filtering of medium and low frequency section.

Further, described taper structure changes damping hole 86 is made up of cone shaped elastic damping hole pipe 16 and slot apertures 15, taper Narrow end is opened on elastic thin-wall 7.Wherein the Young's modulus of cone shaped elastic damping hole pipe 16 is wanted than the Young's modulus of elastic thin-wall 7 Greatly, can be with change in fluid pressure stretching or compression；The Young's modulus of slot apertures 15 is than the Young's modulus of cone shaped elastic damping hole pipe 16 Want big, can be with fluid opened by pressure or closedown.Therefore when the fluctuating frequency of pressure falls at high band, c-type cavity volume filter construction rises Filter action, cone shaped elastic damping hole pipe 16 and slot apertures 15 are all in Figure 10 (a) state；And when ripple frequency falls at Mid Frequency Time, filter construction becomes c-type cavity volume filter construction and elastic thin-wall 7 filter structure concurs, and cone shaped elastic damps Hole pipe 16 and slot apertures 15 are all in Figure 10 (a) state；When ripple frequency falls at some specific Frequency, filter construction Become plug-in type connection in series-parallel H mode filter, c-type cavity volume filter construction and elastic thin-wall filter structure to concur, taper Elastic damping hole pipe 16 and slot apertures 15 are all in Figure 10 (b) state, due to the intrinsic frequency quilt of plug-in type connection in series-parallel H mode filter It is designed as consistent with these particular low frequency ripple frequencies, the system that fundamental frequency energy is big can be played preferable filter effect；Work as arteries and veins Dynamic frequency fall the low-frequency range beyond some CF time, cone shaped elastic damping hole pipe 16 and slot apertures 15 are all in Figure 10 (c) State.The design of such structure changes wave filter both ensure that the full frequency band full working scope filtering of hydraulic system, reduces again normal work The pressure loss of wave filter under condition, it is ensured that the hydraulic pressure rigidity of system.

The present invention can also the pulsation decay of solid line operating mode self-adaptive pressure.When hydraulic system working conditions change, both executive components Suddenly stop or running, and when the opening of valve changes, the characteristic impedance of pipe-line system can be caused to undergo mutation, so that former pipe Pressure curve with change in location in time in road changes the most therewith, then the position of pressure peak also changes.Due to the present invention The axial length of wave filter be designed as pulsing wavelength, and the connection in series-parallel H mode filter group of wave filter more than system main pressure Cavity volume length, the length of S type cavity volume wave filter and the length of elastic thin-wall and wave filter axial length equal, it is ensured that pressure Peak is constantly in the effective range of wave filter；And the taper structure changes damping hole of connection in series-parallel H mode filter is opened On elastic thin-wall, be uniformly distributed in the axial direction so that pressure peak change in location to the performance of wave filter almost without shadow Ring, it is achieved thereby that operating mode adaptive-filtering function.Suitable in view of three kinds of filter structure axial dimensions and wave filter, this is relatively Big size also ensure that hydraulic filter possesses stronger pressure fluctuation damping capacity.

The method that the hydraulic filter using the present invention carries out hydraulic pulsation filtering is as follows:

1), hydraulic fluid enters S type cavity volume wave filter by input pipe, and the cavity volume of expansion absorbs unnecessary liquid flow, completes height The filtering of pressure fluctuation frequently；

2), by S type elastic thin-wall 87 forced vibration, consume the pressure fluctuation energy of fluid, complete intermediate frequency pressure fluctuation Filtering；

3), by connection in series-parallel H mode filter group, and taper structure changes damping hole, taper insertion pipe and fluid produce altogether Shake, consume pulsation energy, complete the filtering of low frequency pulsation；

4), the axial length of wave filter is designed as more than hydraulic system main pressure pulsation wavelength, and the filter of connection in series-parallel H type Ripple device length, S type cavity volume filter length and S type elastic thin-wall 87 length are equal with filter length, make pressure peak position It is constantly in the effective range of wave filter, it is achieved the filtering of pressure fluctuation when system condition changes；

5), by the flexible of the cone shaped elastic damping hole pipe of taper structure changes damping hole and the switch of slot apertures, pressure is completed Pulsation adaptive-filtering.
