Pafupipafupi ogwirizana 1khz akupanga impedical Perlerizer

Kuchuluka kwa pafupipafupi akupanga peresel Telerrizer ya ma transduces a ultrasounds

BwanjiKuyesa magwiridwe antchito a akupanga?

Kuti muone momwe akugwirira ntchito dongosolo la akupanga, ndikofunikira kusanthula mbali ziwiri: magawo ndi zovomerezeka:

1) magawo:

Perperical Perchzer itha kugwiritsidwa ntchito kuwunika magwiridwe antchito osiyanasiyana monga ma transalectic a piezzoelectric, ndi machitidwe onse osinthika (ma transducers kuphatikiza nyanga, nkhungu). Kusanthula kwa zida zopanga zida za chipangizo chokhala ndi Perserity Percher, magawo ofunikira kwambiri ali motere:

FS: Nthawi zambiri makina osinthika, mwachitsanzo, kugwiritsa ntchito pafupipafupi dongosolo la kugwedezeka, kuyenera kukhala pafupi ndi mtengo womwe wayembekezeredwa momwe mungathere ndipo ayenera kufanana ndi magetsi.

Makina oyeretsa, njira zapamwamba za kuperewera kwa Hebitor, zili bwino.

Kwa owotcha pulasitiki kapena akupanga makina, ngati nyanga kapena nkhungu singafanane, pafupipafupi za kusinthika kwa pibibrator isiya ntchito yogwira ntchito.

R1: kukana mwamphamvu, kukana kwa mndandanda wa magawo a pierzoelectric. Kutsuka kapena kuwotcherera kwa ma viberratoors, nthawi zambiri pakati5 ω ndi 20 ω. Ngati ndi yayikulu kwambiri, mabilogalamu kapena dongosolo logwedezeka limakhala ndi mavuto, monga njira yosinthira ya madera kapena yotsika kwambiri, komanso moyo wafupifupi wa pibibrator.

QM: Cholinga cha makina, chotsimikizika ndi njira yolowera, QM = FS / (F2 - F1), Hoyikira Qm, abwinoko, chifukwa apamwamba a QM, okwera kwambiri; Koma qm iyenera kufanana ndi magetsi, mtengo wa qm ndiwokwera kwambiri mphamvu sizikugwirizana.

Kuyeretsa nyongolotsi, mtengo wapamwamba wa QM, wabwino. Nthawi zambiri, Qm ya zm yoyeretsa iyenera kukhala pakati pa 500 ndi 1000. Ngati ndi yotsika kwambiri, kusinthasintha kwamphamvu kumakhala kochepa. Ngati ndiokwera kwambiri, mphamvu sizingafanane.

Pakupanga ma froding kapena makina, mtengo wa qm wa vibrator nthawi zambiri umakhala pafupifupi 500 ~ 1000, ndipo kachitidwe kali ndi 1500 ~ 3000 ~ 3000. Ngati ndi yotsika kwambiri, kuwononga mphamvu kuli kochepa, koma sikungakhale kwakukulu kwambiri, chifukwa mphamvu yapamwamba kwambiri yopapatiza, ndiye kuti, mphamvu sizivuta kugwira ntchito mobwerezabwereza.

CT: Camicacita yaulere, mtengo wa chipangizo cha piezoelectric pa 1 KHz. Mtengo uwu umakhala wosasintha ndi mtengo womwe umayesedwa ndi digito carter. Chomera ichi chimachotsa mphamvu ya mphamvu ya C1 kuti atenge stacitance capatance C0, C0 = CT - C1. Mukamagwiritsa ntchito, moyenera C0 ndi chifundo.

Mu kapangidwe ka makina ochapira kapena makina akupanga, moyenera C0 imatha kuwonjezera mphamvu ya mphamvu. Pali njira ziwiri zogwiritsira ntchito ndalama, zikufanana ndi zolemba zingapo.

FP: Anti - pafupipafupi, pafupipafupi, pafupipafupi nthambi yofanana ya piezoelectric. Pa pafupipafupi, zombukika za zmax wa piezoelectric fibraser ndiye wamkulu kwambiri. Ngati anti - kulowerera kotsalira zmax kuli kotsika, nyongayo ili ndi vuto.

2) Zojambula

Chidule Penler chimapereka mitundu isanu yolumikizirana mitundu isanu, ndipo chinda chagalasi chimakhala ndi tanthauzo lofunikira pakuzindikira piezoelertc zida. Kugwirira ntchito kugwedeza kwa piezoelectric ibrator kapena njira yozungulira imatha kuweruzidwa mwachindunji ndi chithunzi chagalasi, yomwe ndi yothandiza komanso yothandiza.

Nthawi zambiri, zovomerezeka ndi zomwe zimachitika zimawonetsera.

Chionetsero:

Circlence Circlence ndi bwalo limodzi, ndipo chithunzi chagalasi chimakhala ndi zochepa chabe komanso zokwanira kwambiri:
