Dab tsi yog ultrasonic impedance analyzer?

Tus kws tshaj lij ultrasonic yog ib qho kev tshwj xeeb siv los ntsuas cov acoustic impedance tus yam ntxwv ntawm cov ntaub ntawv lossis cov khoom siv ntawm ultrasonic zaus. Nws cia kom pom kev tiv thaiv los ntawm suab zog pom raws li nws hais tawm los ntawm ib qho nruab nrab thiab yog cov cuab yeej tseem ceeb hauv cov acoustics, cov ntaub ntawv science, thiab kev sim tshuaj.

Tub ntxhais lub hauv paus ntsiab lus: acoustic impedance ntsuas ntsuas ntsuas kev ntsuas

Acoustic impedance (Z) yog ib qho khoom siv hauv cov khoom siv thiab sib npaug rau cov khoom ntawm nws qhov ntom ntom (ρ) thiab lub suab nrawm (v). Cov mis yog z = ρ × v. Cov cuab yeej ua cov ntsuas hauv qab no:
1. Cov paib kis tau: Ib lub cim ultrasonic ntawm cov paub ntau zaus thiab amplitude yog kis mus rau cov khoom raug ntsuas.
2. Kev txais tos txais: Lub teeb liab ultrasonic tau ntes tom qab kev xav lossis kis los ntawm cov khoom.
3. Cov kev suav cov ntaub ntawv: Qhov kev sib txawv thiab cov ntsiab lus sib txawv ntawm qhov xwm txheej thiab tau txais cov cim qhia tau muab piv, thiab lub acoustic impedance tus nqi yog xam tau siv tus qauv lub cev.

Daim ntawv thov tseem ceeb tshaj plaws

Ultrasonic impedance Analyzers muaj ntau yam kev siv. Lawv lub luag haujlwm tseem ceeb yog los txiav txim cov khoom siv lossis kuaj pom kev tsis xws luag los ntawm kev siv acoustic impedance sib txawv. Cov ntawv thov feem muaj xws li:
● Cov Khoom Siv R & D: Ntsuas cov acoustic impedance ntawm cov hlau, ceramics pab txhim kho cov ntaub ntawv tsim kho thiab ua haujlwm zoo.
Kev sim ua tsis zoo: Ntes cov khoom tsis xws luag xws li cov kab nrib pleb, npuas, thiab delamination nyob rau hauv cov ntaub ntawv. Thaum cov khoom siv muaj qhov tsis xws luag, lub acoustic impedance ntawm qhov chaw kho puas muaj qhov txawv, thiab qhov ntsuas tuaj yeem ntes qhov kev hloov no.
● Ntaus Kev Kuaj Ntaus: Siv rau kev ua tau zoo ntawm acoustic cov khoom siv xws li ultrasonic sensors, thiab ultrasonic probes los xyuas kom meej tias lawv cov acoustic impedance tsim qauv tsim.
● Biomedical: Hauv kev kho mob kho mob, nws tuaj yeem siv los tshawb xyuas cov khoom siv kho mob cov khoom, piv txwv, txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau lossis kev noj qab haus huv ntawm cov nqaij mos.

Cov ntsiab lus tseem ceeb

Thaum xaiv lossis siv cov ntsuas no, them nyiaj rau cov ntsiab lus hauv qab no, uas cuam tshuam ncaj qha ntsuas qhov tseeb thiab qhov muaj feem xyuam:
● Kev ntsuas ntau qhov ntau: Feem ntau npog cov hlua khi kom ntau, piv txwv li siv tau rau cov khoom sib txawv, thaum cov khoom qis dua rau cov qauv tuab).
Cleporterance Ntsuas ntsuas ntau yam: li ntsuas hauv Rayles, qhov no yuav tsum tau phim lub impedance ntawm cov khoom siv tau raug ntsuas (piv txwv li 413
●Cov Muaj tseeb thiab rov ua dua: Qhov tseeb dua ntxiv cov ntaub ntawv kev ntseeg tau yooj yim; Kev ua kom rov ua tiav cov kev ntsuas sib xws thoob plaws ntau qhov kev ntsuas.
● Kev sojntsuam: Xaiv raws li ntsuas ntsuas (kev xav lossis kis). Yuav kom haum rau cov qauv nrog kev nkag tau ntawm ib sab, thaum kis tau cov kev sib kis tau siv rau ntawm ob sab.
