Ultrasound ka boeona thuto ea tekheniki

1. Theknoloji ea ho lemoha ka laser ultrasound

Theknoloji ea ho lemoha mahlaseli a laser ke ho sebelisa laser ea pulsed ho hlahisa pulse ea ultrasonic ho lemoha mosebetsi.Laser e ka susumetsa maqhubu a ultrasonic ka ho hlahisa phello ea mocheso oa mocheso kapa ka ho sebelisa thepa ea bohareng.Melemo ea laser ultrasound e bonahala haholo ka likarolo tse tharo:

(1) E ka ba ho lemoha sebaka se selelele, laser ultrasound e ka ba propagation ea sebaka se selelele, ho fokotseha ha mokhoa oa ho phatlalatsa ho nyenyane;

(2) Kopano e sa tobang, ha e hloke ho kopana ka ho toba kapa haufi le workpiece, ts'ireletso ea ho lemoha e phahame;

(3) Tharollo e phahameng ea ho lemoha.

Ho itšetlehile ka melemo e ka holimo, laser ultrasonic discovery e loketse ka ho khetheha bakeng sa ho lemoha nako ea sebele le ea marang-rang ea mosebetsi sebakeng se thata, 'me liphetho tsa ho lemoha li bontšoa ke litšoantšo tse potlakileng tsa ultrasonic scanning.

Leha ho le joalo, laser ultrasound le eona e na le mefokolo e itseng, joalo ka ho lemoha ha ultrasonic ka qeto e phahameng empa e batla e le tlase haholo.Hobane mokhoa oa ho lemoha o kenyelletsa tsamaiso ea laser le ea ultrasonic, mokhoa o feletseng oa ho lemoha laser ultrasonic o moholo ka bongata, o rarahaneng ka sebopeho le theko e phahameng.

Hona joale, theknoloji ea laser ultrasound e ntse e tsoela pele ka litsela tse peli:

(1) Lipatlisiso tsa thuto mabapi le mochine oa laser ultrafast excitation le tšebelisano le litšobotsi tse nyenyane tsa laser le microscopic particles;

(2) Online positioning monitoring in industry.

2.Theknoloji ea tlhahlobo ea motlakase ea ultrasonic

Electromagnetic ultrasonic wave (EMAT) ke ts'ebeliso ea mokhoa oa ho kenya motlakase oa motlakase ho susumetsa le ho amohela maqhubu a ultrasonic.Haeba motlakase oa maqhubu a phahameng a pota-potiloe ka har'a coil haufi le holim'a tšepe e lekantsoeng, ho tla ba le motlakase o susumelitsoeng oa maqhubu a tšoanang ka tšepe e lekantsoeng.Haeba matla a khoheli a sa khaotseng a sebelisoa ka ntle ho tšepe e lekantsoeng, motlakase o kentsoeng o tla hlahisa matla a Lorentz a maqhubu a tšoanang, a sebetsang holim'a lesela la tšepe le lekantsoeng ho etsa hore ho thothomele nako le nako ea sebopeho sa kristale sa tšepe e lekantsoeng, ho susumetsa maqhubu a ultrasonic. .

Electromagnetic ultrasonic transducer e entsoe ka high-frequencycoil, matla a khoheli a kantle le conductor e lekantsoeng.Ha ho lekoa sesebelisoa, likarolo tsena tse tharo li nka karolo hammoho ho phethela phetoho ea theknoloji ea mantlha ea electromagnetic ultrasound lipakeng tsa motlakase, makenete le molumo.Ka ho lokisoa ha sebopeho sa li-coil le boemo ba ho behoa, kapa ho lokisoa ha mekhoa ea 'mele ea sekhahla se phahameng sa maqhubu, Ho fetola boemo ba matla a mokhanni ea lekiloeng, kahoo ho hlahisa mefuta e sa tšoaneng ea ultrasound.

3.Theknoloji ea ho lemoha ultrasound e kopantsoeng le moea

Theknoloji ea ho lemoha moea e kopantsoeng ke moea ke mokhoa o mocha oa tlhahlobo o sa amaneng le o sa senyeheng o nang le moea e le mokhoa oa ho kopanya.Melemo ea mokhoa ona ha e kopane, ha e hlasele, ebile ha e senye ka ho feletseng, ho qoba mefokolo e meng ea ho lemoha ha ultrasound ea setso.Lilemong tsa morao tjena, theknoloji ea ho lemoha ultrasonic e kopantsoeng le moea e 'nile ea sebelisoa haholo ho lemoha sekoli sa thepa e kopantsoeng, tlhahlobo ea ts'ebetso ea thepa, le ho lemoha ka mokhoa o itekanetseng.

Hajoale, lipatlisiso tsa thekenoloji ena li shebane haholo le litšoaneleho le mohopolo oa moea oa coupling excitation ultrasonic field, le lipatlisiso tsa ts'ebetso e phahameng le probe ea moea o tlase oa lerata.The COMSOL Multi-physical field simulation software e sebelisetsoa ho etsa mohlala le ho etsisa tšimo ea ultrasonic e kopantsoeng le moea, e le ho sekaseka bofokoli ba boleng, palo le litšoantšo mesebetsing e hlahlobiloeng, e ntlafatsang ts'ebetso ea ho lemoha le ho fana ka tlhahlobo e molemo bakeng sa ts'ebeliso e sebetsang. ea ultrasound e sa amaneng le motho.

Ithute ka theknoloji e thusoang ke ultrasound

Patlisiso ea thekenoloji e thusitsoeng ke Ultrasound haholo-holo e bua ka eona motheong oa ho se fetole mokhoa le molao-motheo oa ultrasound, motheong oa ho sebelisa likarolo tse ling tsa theknoloji (joalo ka ho fumana tlhahisoleseling le theknoloji ea ho sebetsa, theknoloji ea tlhahiso ea litšoantšo, theknoloji ea bohlale ba maiketsetso, jj.) , thekenoloji ea mehato ea ho lemoha ultrasonic (ho fumana matšoao, tlhahlobo ea matšoao le ho sebetsa, ho nahana ka phoso) ho ntlafatsa, e le ho fumana liphetho tse nepahetseng haholoanyane tsa ho lemoha.

1.Nerual network techology

Neural network (NNs) ke mokhoa oa algorithmic oa lipalo o etsisang litšobotsi tsa boits'oaro ba liphoofolo tsa NN mme o etsa ts'ebetso ea tlhaiso-leseling e bapileng.Marang-rang a itšetlehile ka ho rarahana ha tsamaiso 'me a finyella morero oa ho sebetsana le tlhahisoleseding ka ho lokisa likamano pakeng tsa palo e kholo ea li-node.

2.Mokhoa oa ho etsa litšoantšo oa 3D

E le tataiso ea bohlokoa ea nts'etsopele ea nts'etsopele ea theknoloji e thusang ea ultrasonic ho lemoha, theknoloji ea 3D imaging (Three-Dimensional Imaging) e boetse e hohetse tlhokomelo ea litsebi tse ngata lilemong tsa morao tjena.Ka ho bonts'a litšoantšo tsa 3D tsa liphetho, liphetho tsa ho sibolla li hlakile ebile li hlakile.
