Description
Technical field
The invention belongs to structural health detection field, and in particular to a kind of multichannel water coincidence ultrasound of macrotype tubular structure
Detection means and its detection method.
Background technology
Macrotype tubular structure is widely used in aviation as air-liquid container, chemical industry smelting vessel and safety guarantee facility etc.
The fields such as space flight, national defence, chemical industry, medical treatment.Due to the generation of internal flaw (crackle, space, field trash) in manufacturing process, and
The evolution of defect and the generation of new defect (crackle, corrosion) during use so that the Non-Destructive Testing of structure becomes difficult.It is super
Sound detection technology, as most widely used, frequency of use highest, a kind of faster nothing of development in five big conventional non-destructive testing technologies
Detection technique is damaged, so that its detection range is wide, detection depth is big, defect location is accurate, high sensitivity, cost are low, easy to use, fast
Spend fast, harmless and the advantages that be easy to onsite application, become the primary selection of such a structure Non-Destructive Testing.
Supersonic detection method can be divided into three kinds of contact, liquid immersion type and empty coupling formula.Contact supersonic detection method is super
Sonic probe, by direct contact infection ultrasonic wave, generally reaches exclusion in a manner of daubing coupling agent between the two with measurand
The effect of air and good contact.Liquid immersion type supersonic detection method is that the ultrasonic wave-coupled between ultrasonic probe and measurand exists
Propagated in fluid passage.Empty coupling formula supersonic detection method is ultrasonic wave-coupled between ultrasonic probe and measurand in air
Middle propagation.For the ultrasound detection of macrotype tubular structure, contact supersonic detection method is due to the reason of daubing coupling agent, efficiency
Lowly, cost is higher, easily pollutes object to be measured, is difficult to automate.The decay of empty coupling formula supersonic detection method detection signal is serious,
Restricted application and easily by Environmental Noise Influence.Two methods relatively above, liquid immersion type supersonic detection method have it is non-contact,
The small, high sensitivity of detection signal decay, efficiency high, applied widely, cost is relatively low, clean environment firendly and is easy to the excellent of automation
Point, therefore as the primary selection of macrotype tubular structure.But due to structural volume is big, quality is big, into closed, be immersed in
To realize that the method for liquid immersion type ultrasound detection is not suitable for such a structure in tank.Therefore, realized by way of spraying water and coupling
The detection of liquid immersion type ultrasonic pulse-echo is the best approach of macrotype tubular structure.
For the above method, how to realize that water coincidence directly decides testing result.1985, Borislav
(US4507969) a kind of ultrasonic liquid jet probe is devised, main implementation is：A nozzle is made, by ultrasonic probe
Place wherein.Change fluid pressure and flow velocity by changing the shape for surrounding runner of being popped one's head in nozzle, by bottom surface portions of popping one's head in
Immerse in liquid, ultrasonic wave-coupled is ejected into measurand surface in a liquid.Detection signal can both be returned by ultrasonic pulse
The mode of ripple is received by same probe, can also be received by transmission mode by the probe of structure opposite side, wherein opposite side is visited
Head is also with identical water spray coupling process.Then, the Fred (4558598) of Boeing devises a kind of ultrasonic linear array
Nozzle, the ultrasonic detection in transmission mode for layer structure (such as honeycomb).The design will be linear by index luffing baffle plate
The ultrasonic transducer runner of array is completely separated, and the ultrasonic wave-coupled of each transducer transmitting sprays in water through respective runner
To body structure surface, detection signal is received by the ultrasonic probe of opposite side.With the extensive use of ultrasound detection, various ultrasound water sprays
Coupling device also emerges in an endless stream, wherein more representational such as US74327B2, US7607594B2, US7798003B2.On
Design principle and the structure for stating patent are all similar with Borislav design.
Relatively for foreign countries, domestic ultrasonic detecting technology is in a booming stage, also there is many scholars
Water spray coupled system is designed and applied.Xu Zhinong etc. (CN10268055A) devises one kind and is based on ultrasound measuring instrument
Immersion probe water spray coupling device, using dismountable multi-pipeline connection by the way of form probe downstream canal, by ultrasonic wave
Couple wherein and be ejected into body structure surface.Haibo Liu etc. (CN103962890A) devises a kind of hydrojet for ultrasound detection
Device, double-deck rectification is realized by double-layer porous sieve structure, it is laminar condition to control current.
Although the water spray coupled system of the above-mentioned detection of liquid immersion type ultrasonic pulse-echo both at home and abroad all design it is relatively reasonable feasible,
But still may not apply in large-scale, tubulose structure, it is mainly disadvantageous in that：1. current are after nozzle ejects
Water circulation system is formed by tank.For large scale system, because detection time is grown, and without sufficiently large tank, can cause
Serious current waste, and increase water scavenging system pressure.2. mainly for the ultrasound detection of planar structure, beam angle is seldom considered
Change, have ignored the beam angle calibration problem to tubular structure ultrasound examination, it is difficult to realize vertical incidence.3. it is mainly
Single pass ultrasound detection, and nozzle overall dimensions are larger, are not easy to integrated and site density the increase of multichannel, Jin Erwu
Method meets the ultrasound detection of large scale structure.
