Ubushakashatsi niterambere ryiterambere rya tekinoroji ya ultrasonic

Ultrasound ubwayo yiga tekinike

1. Tekinoroji ya Laser ultrasound

Ikoreshwa rya tekinoroji ya Laser ultrasonic nugukoresha laser ya pulsed kugirango itange ultrasonic pulse kugirango umenye akazi. Lazeri irashobora gukangura ultrasonic waves itanga ingufu za elastique yumuriro cyangwa ikoresheje ibikoresho byo hagati. Ibyiza bya ultrasound ya laser bigaragarira cyane mubintu bitatu:

(1) Irashobora kuba intera ndende, laser ultrasound irashobora kuba intera ndende, kwiyongera mubikorwa byo gukwirakwiza ni bito;

(2) Guhuza bitaziguye, ntukeneye guhuza bitaziguye cyangwa hafi yakazi, umutekano wo gutahura ni mwinshi;

(3) Icyemezo cyo gutahura cyane.

Ukurikije ibyiza byavuzwe haruguru, laser ultrasonic detection irakwiriye cyane cyane mugihe nyacyo no kumurongo wo gutahura igihangano cyakorewe ahantu habi, kandi ibisubizo byo gutahura byerekanwa na ultrasonic scanning imaging.

Nyamara, ultrasound ya laser nayo ifite ibibi bimwe na bimwe, nka ultrasonic detection ifite imiterere ihanitse ariko ikagabanuka cyane. Kuberako sisitemu yo gutahura ikubiyemo sisitemu ya laser na ultrasonic, sisitemu yuzuye ya laser ultrasonic sisitemu nini nini mubunini, igoye mumiterere kandi ihenze cyane.

Kugeza ubu, tekinoroji ya laser ultrasound iratera imbere mubyerekezo bibiri:

.

(2) Gukurikirana imyanya kumurongo mubikorwa byinganda.

2.Tekinoroji ya electromagnetic ultrasonic

Electromagnetic ultrasonic wave (EMAT) nugukoresha uburyo bwa electromagnetic induction yo gukangura no kwakira imiraba ya ultrasonic. Niba amashanyarazi yumurongo mwinshi azunguruka muri coil hafi yubuso bwicyuma cyapimwe, hazabaho umuyoboro uterwa numurongo umwe mubyuma byapimwe. Niba umurima wa magnetiki uhoraho ushyizwe hanze yicyuma cyapimwe, umuyoboro watewe uzana ingufu za Lorentz yumurongo umwe, ikora kumurongo wapimwe wapimwe kugirango itume ihindagurika ryigihe cyimiterere ya kirisiti yicyuma cyapimwe, kugirango itere imiraba ya ultrasonic .

Electromagnetic ultrasonic transducer igizwe na frequency-coilcoil, umurima wa magneti wo hanze hamwe nuyobora. Iyo ugerageza igihangano, ibi bice bitatu byitabira hamwe kugirango birangize guhinduranya tekinoroji yibanze ya ultrasound ya electromagnetic hagati yamashanyarazi, magnetisme nijwi. Binyuze muguhindura imiterere ya coil hamwe nu mwanya wabyo, cyangwa guhindura ibipimo bifatika bya coil-yumurongo mwinshi, Guhindura imbaraga zumuyoboro wapimwe, bityo bikabyara ubwoko butandukanye bwa ultrasound.

3.Ikoreshwa rya tekinoroji ya ultrasound

Ikoranabuhanga rya ultrasonic detection tekinoroji nuburyo bushya budahuza ultrasonic nondestructive uburyo bwo gupima hamwe numwuka nkuburyo bwo guhuza. Ibyiza byubu buryo ni ukudahuza, kudatera, no kutangiza rwose, wirinda ibibi bimwe na bimwe byerekana ultrasound. Mu myaka yashize, tekinoroji ya ultrasonic yo gutahura ikirere yakoreshejwe cyane mugutahura inenge yibikoresho, gusuzuma imikorere, no gutahura byikora.

Kugeza ubu, ubushakashatsi bw’ikoranabuhanga bwibanze cyane cyane ku biranga n’imyumvire y’imyuka ihumanya ikirere ultrasonic, hamwe nubushakashatsi bwakozwe neza hamwe n’urusaku ruke rwo mu kirere. Porogaramu ya simusiga ya COMSOL ikoreshwa muburyo bwo kwerekana no kwigana umurima wa ultrasonic uhujwe n’ikirere, kugira ngo usesengure inenge zujuje ubuziranenge, ubwinshi n’amashusho mu mirimo yagenzuwe, biteza imbere imikorere ikanatanga ubushakashatsi bwingirakamaro mu bikorwa bifatika. ya ultrasound idahuza.

Kwiga kuri tekinoroji ifashwa na ultrasound

Ubushakashatsi bwa tekinoroji ya Ultrasound bwerekeza cyane cyane ku kudahindura uburyo n’amahame ya ultrasound, hashingiwe ku gukoresha izindi nzego z’ikoranabuhanga (nko gushaka amakuru no gutunganya ikoranabuhanga, ikoranabuhanga ryerekana amashusho, ikoranabuhanga ry’ubwenge, n'ibindi) , tekinoroji yintambwe yo gutahura ultrasonic (kugura ibimenyetso, gusesengura ibimenyetso no gutunganya, kwerekana amashusho), kugirango ubone ibisubizo nyabyo byo gutahura.

1.Numuyoboro wa tekinorojiology

Umuyoboro wa Neural (NNs) ni algorithm ya mibare ya algorithmic yigana ibiranga imyitwarire yinyamaswa NNs kandi ikora ikwirakwizwa ryamakuru atunganijwe. Umuyoboro uterwa nuburyo bugoye bwa sisitemu kandi ugera ku ntego yo gutunganya amakuru uhindura amasano hagati yumubare munini wa node.

2.3 D tekinike yo gufata amashusho

Nicyerekezo cyingenzi cyiterambere cyiterambere rya ultrasonic detection yubufasha bwikoranabuhanga, tekinoroji ya 3 D yerekana amashusho (Three-Dimensional Imaging) nayo yashishikaje intiti nyinshi mumyaka yashize. Mugaragaza amashusho ya 3D yibisubizo, ibisubizo byo gutahura birasobanutse kandi byihuse.
