Kev tshawb nrhiav thiab kev txhim kho kev taw qhia ntawm ultrasonic nrhiav tshuab

Ultrasound nws tus kheej kev kawm

1. Laser ultrasound nrhiav tshuab

Laser ultrasonic nrhiav tshuab yog siv cov mem tes laser los tsim cov ultrasonic pulse los ntes cov workpiece. Lub laser tuaj yeem txhawb nqa ultrasonic nthwv dej los ntawm kev tsim cov nyhuv thermal elastic lossis siv cov khoom siv nruab nrab. Qhov zoo ntawm laser ultrasound yog feem ntau xav txog peb yam:

(1) tuaj yeem tshawb pom qhov ntev, laser ultrasound tuaj yeem ua rau kev nthuav dav ntev, qhov txo qis hauv cov txheej txheem nthuav tawm me me;

(2) Tsis yog kev sib cuag ncaj qha, tsis xav tau kev sib cuag ncaj qha lossis ze rau ntawm qhov chaw ua haujlwm, kev kuaj pom kev nyab xeeb siab;

(3) Kev kuaj xyuas siab.

Raws li qhov zoo saum toj no, laser ultrasonic nrhiav tau tshwj xeeb tshaj yog tsim rau lub sijhawm tiag tiag thiab kev tshawb nrhiav hauv online ntawm lub workpiece nyob rau hauv ib puag ncig hnyav, thiab cov txiaj ntsig kev tshawb pom tau tshwm sim los ntawm kev kuaj xyuas ultrasonic ceev.

Txawm li cas los xij, laser ultrasound kuj muaj qee qhov tsis zoo, xws li kev kuaj xyuas ultrasonic nrog kev daws teeb meem siab tab sis kuj tsis tshua muaj siab. Vim tias qhov kev kuaj pom muaj xws li laser thiab ultrasonic system, ua tiav laser ultrasonic nrhiav kom tau qhov system loj hauv ntim, complex hauv cov qauv thiab tus nqi siab.

Tam sim no, laser ultrasound tshuab yog tsim nyob rau hauv ob txoj kev:

(1) Kev tshawb fawb kev tshawb fawb ntawm laser ultrafast excitation mechanism thiab kev sib cuam tshuam thiab microscopic yam ntxwv ntawm laser thiab microscopic hais;

(2) Online positioning xyuas hauv industrially.

2.Electromagnetic ultrasonic nrhiav tshuab

Electromagnetic ultrasonic yoj (EMAT) yog siv cov txheej txheem electromagnetic induction los txhawb thiab tau txais ultrasonic tsis. Yog tias qhov hluav taws xob ntau zaus tau xa mus rau hauv ib lub kauj ze ntawm qhov ntsuas hlau, yuav muaj qhov cuam tshuam tam sim no ntawm tib zaus hauv cov hlau ntsuas. Yog tias qhov chaw sib nqus tas mus li raug siv sab nraum cov hlau ntsuas, qhov cuam tshuam tam sim no yuav tsim lub zog Lorentz ntawm tib zaus, uas ua rau cov ntsuas hlau ntsuas kom ua rau lub sijhawm vibration ntawm cov qauv siv lead ua ntawm cov ntsuas hlau, txhawm rau txhawb ultrasonic tsis. .

Electromagnetic ultrasonic transducer yog tsim los ntawm high-frequencycoil, sab nraud magnetic teb thiab ntsuas tus neeg xyuas pib. Thaum kuaj cov khoom ua haujlwm, peb ntu no koom ua ke ua kom tiav qhov kev hloov pauv ntawm cov thev naus laus zis ntawm electromagnetic ultrasound ntawm hluav taws xob, hlau nplaum thiab suab. Los ntawm kev hloov kho ntawm lub coil qauv thiab qhov chaw tso kawm, los yog kev hloov ntawm lub cev tsis muaj zog coil, hloov qhov xwm txheej quab yuam ntawm tus neeg xyuas pib kuaj, yog li tsim ntau hom ultrasound.

3.Cua-coupled ultrasound nrhiav tshuab

Huab cua sib txuas ultrasonic nrhiav kom tau thev naus laus zis yog ib qho tshiab tsis tiv tauj ultrasonic nondestructive kuaj txoj kev nrog huab cua raws li qhov nruab nrab coupling. Qhov zoo ntawm txoj kev no yog tsis sib cuag, tsis muaj kev cuam tshuam, thiab tsis muaj kev puas tsuaj kiag li, zam qee qhov tsis zoo ntawm kev kuaj ultrasound. Nyob rau hauv xyoo tas los no, huab cua-coupled ultrasonic nrhiav kom tau tshuab tau dav siv nyob rau hauv qhov tsis xws luag ntawm cov ntaub ntawv sib xyaw, kev ntsuam xyuas cov khoom siv, thiab kev tshawb nrhiav tsis siv neeg.

Tam sim no, kev tshawb fawb ntawm cov thev naus laus zis no feem ntau tsom rau cov yam ntxwv thiab kev xav ntawm huab cua coupling excitation ultrasonic teb, thiab kev tshawb fawb ntawm kev ua haujlwm siab thiab tsis tshua muaj suab nrov cua coupling sojntsuam. COMSOL multi-physical field simulation software yog siv los ua qauv thiab simulate cov huab cua-coupled ultrasonic teb, thiaj li los soj ntsuam qhov zoo, ntau thiab cov duab tsis xws luag hauv kev soj ntsuam ua haujlwm, uas txhim kho qhov kev tshawb pom zoo thiab muab kev tshawb fawb zoo rau daim ntawv thov. ntawm tsis sib cuag ultrasound.

Kawm txog kev siv tshuab ultrasound-pab

Ultrasound-pab thev naus laus zis kev tshawb fawb feem ntau yog hais txog nws ntawm lub hauv paus tsis hloov txoj kev ultrasound thiab lub hauv paus ntsiab lus ntawm kev siv lwm yam kev siv thev naus laus zis (xws li kev nrhiav thiab kev siv thev naus laus zis, kev tsim duab thev naus laus zis, thev naus laus zis thev naus laus zis, thiab lwm yam.) , thev naus laus zis ntawm kev kuaj xyuas ultrasonic cov kauj ruam (cov teeb liab tau txais, teeb liab tsom xam thiab kev ua tiav, cov duab tsis zoo) kev ua kom zoo, thiaj li tau txais txiaj ntsig zoo dua nrhiav pom.

1.Nerual network techn uaology

Neural network (NNs) yog tus qauv lej algorithmic uas coj tus cwj pwm coj tus cwj pwm ntawm tsiaj NNs thiab ua cov ntaub ntawv sib txuas ua ke. Lub network nyob ntawm qhov nyuaj ntawm qhov system thiab ua tiav lub hom phiaj ntawm kev ua cov ntaub ntawv los ntawm kev kho cov kev sib txuas ntawm ntau cov nodes.

2.3D imaging txheej txheem

Raws li ib qho tseem ceeb ntawm txoj kev loj hlob ntawm ultrasonic nrhiav auxiliary technology txoj kev loj hlob, 3 D imaging (Three-Dimensional Imaging) thev naus laus zis kuj tau nyiam ntau tus kws tshawb fawb hauv xyoo tas los no. Los ntawm kev ua kom pom cov duab 3D ntawm cov txiaj ntsig, cov txiaj ntsig kev tshawb pom muaj ntau qhov tshwj xeeb thiab nkag siab.
