Siab ntau sib xws 1kHz ultrasonic impedance analyzer

Siab siab tau siv cov neeg yuam kev ultrasonic kom pom zoo rau ultrasound xa khoom

Yuav Ua Li CasTxhawm rau ntsuas kev ua tau zoo ntawm ultrasonic transducer?

Txhawm rau ntsuas qhov kev ua tau zoo ntawm kev co tshuab kev co ultrasonic, nws yog qhov tsim nyog los soj ntsuam los ntawm ob yam: tsis sib xws thiab txoj kev lees paub:

1) tsis muaj:

Lub impedance analyzer tuaj yeem siv los ntsuas kev ua tau zoo ntawm ntau yam xws li Piezoeltric Cerams, thiab tag nrho cov co tshuab ntxhua khaub ncaws (transducers ntxiv kub, pwm). Kev tsom xam ntawm cov khoom siv ultrasonic nrog cov neeg tsis sib haum xeeb, cov tsis tseem ceeb tshaj plaws yog raws li hauv qab no:

FS: Cov neeg kho tshuab cov kev ua haujlwm ntau zaus, piv txwv li cov kev ua haujlwm ntawm qhov kev cai vibration, yuav tsum tau ze rau cov nqi uas tsim nyog hauv tus qauv thiab yuav tsum phim lub zog hluav taws xob ua haujlwm.

Rau lub tshuab ntxuav, siab dua resonant zaus zaus muaj zaus muaj feem ntawm cov vibrator, qhov zoo dua.

Rau cov qauv yas lossis ultrasonic machining, yog tias lub tshuab raj lossis pwm tsim qauv tsis yog, cov neeg uas muaj peev xwm ntawm lub vibrator yuav hloov kho los ntawm kev ua haujlwm.

R1: Siv hluav taws xob tsis kam, cov tsis kam ntawm cov duab piezoelectric Vibrators, tus me dua zoo dua nyob hauv tib yam kev txhawb nqa. Rau kev ntxuav lossis vuam Vibrators, nws yog feem ntau ntawm5 ω thiab 20 ω. Yog tias nws loj dhau lawm, lub vibrator lossis vibrator lossis kev co cov txheej txheem yuav muaj teeb meem, xws li kev sib cav sib ceg lossis kev hloov pauv tau qis, thiab lub neej luv luv ntawm lub cev.

QM: Cov Tshuab Kho Kom Zoo, txiav txim siab los ntawm Txoj Kev Cwj Pwm Cluction, QM = FS / (F2 - F1), Hapher lub QM, qhov zoo dua, vim tias ntau dua cov QM, ntau dua cov vibrator efficiency; Tab sis qm yuav tsum phim lub zog hluav taws xob, tus nqi QM yog siab dhau lub zog hluav taws xob tsis phim.

Txog kev ntxuav lub vibrator, ntau dua tus nqi QM, qhov zoo dua. Feem ntau hais lus, cov qm ntawm kev tu vibrator yuav tsum tau nyob nruab nrab ntawm 500 thiab 1000. Yog tias nws tsawg dhau, lub vibrator efficiency yog tsawg. Yog tias nws tseem siab dhau, lub zog hluav taws xob tsis tuaj yeem sib phim.

Txog ultrasonic vuam lossis machining, QM tus nqi ntawm lub vibrator nws tus kheej feem ntau nyob ib ncig ntawm 500 ~, thiab tag nrho cov kab ke yog 1500 ~ 3000. Yog tias nws qis dhau, qhov kev co ua tau zoo, tab sis nws tsis tuaj yeem nyuaj, yog qhov nyuaj ua haujlwm ntawm cov khoom uas rov ua haujlwm ntau zaus, thiab cov cuab yeej tsis tuaj yeem ua haujlwm.

CT: Pub dawb capacitance, lub peev xwm muaj peev xwm ntawm lub piezoelectric ntaus ntawv ntawm 1 KHz. Tus nqi no yog sib xws nrog tus nqi ntsuas los ntawm cov ntsuas hluav taws xob. Tus nqi no rho tawm cov c1 muaj tseeb capacitance c0, c0 = C1. Thaum siv, sib npaug C0 nrog inductance.

Nyob rau hauv Circuit Tsim ntawm lub tshuab ntxhua khaub ncaws lossis tshuab ultrasonic, kom zoo tshaj c0 tuaj yeem nce lub zog hluav taws xob ntawm lub zog. Muaj ob txoj hauv kev rau kev siv lub inductor tshuav nyiaj li cas, thaum sib txuas thiab sib tshooj.

FP: anti - Revonations Zaus, tus uas muaj ib zaus ntawm cov ceg sib txuas ntawm cov piezoelectric vibrator. Ntawm qhov zaus no, lub impedance zmax ntawm lub piezoelectric vibrator yog qhov loj tshaj plaws. Yog tias anti - resonant impedance zmax yog tsawg, lub vibrator muaj teeb meem.

2) Graphics

Lub impedance analyzer muab tsib hom kev sib koom tes cov cim kos duab, thiab cov cim logarithmic muaj qhov tseem ceeb rau kev kuaj pom ntawm cov khoom siv piezoelectric. Qhov kev co kev ua haujlwm ntawm lub piezoelectric chrrator lossis lub kaw lus vibrating tuaj yeem raug txiav txim ncaj qha los ntawm cov qauv logarithmic, uas yog qhov ua rau pom tseeb thiab siv tau.

Nyob rau hauv ib txwm muaj xwm txheej, cov kev ua hauj lwm lub voj voog thiab kev nkhaus nkhaus yog raws li qhia hauv daim duab hauv qab no.

Ua yeeb yam:

Cov kev lag luam uas yog ib lub voj voog, thiab lub logarithmic graph muaj tsuas yog ib khub ntawm qhov tsawg kawg nkaus thiab qhov tseem ceeb tshaj plaws:
