Yini i-ultrasonic impedance analyzer?

I-Ultrasonic Impedance Analyzer iyithuluzi elikhethekile elisetshenziselwa ukukala izici ze-acoustic ukungcola kwezinto zokwakha noma amadivaysi kuma-ultrasonic. Icacisa ukumelana okuhlangane nayo ngamandla anomsindo njengoba isakaza nge-medium futhi iyithuluzi eliyisisekelo emikhakheni yama-acoustics, isayensi yezinto zokwakha, kanye nokuhlolwa kwezimboni.

Isimiso Esiyisisekelo: I-Acoustic Imperance Ukulinganisa Logic

I-Acoustic Impodance (Z) impahla engokwemvelo yezinto ezibonakalayo futhi ilingana nomkhiqizo wobude bayo (ρ) kanye nejubane lomsindo (v). Ifomula yi-Z = ρ × ×. Ithuluzi lenza izilinganiso ezilandelayo:
1
2. Ukwemukelwa kwesiginali: Isiginali ye-ultrasonic ithathwe ngemuva kokukhombisa noma ukuhambisa kusuka entweni.
I-3. Ukubalwa kwedatha: Ukuphakama kanye nokwehluka kwesigaba phakathi kwesigameko futhi kutholwe amasiginali atholwayo aqhathaniswa, futhi inani le-acoustic litedance libalwa kusetshenziswa imodeli yenyama.

Izimo eziphambili zesicelo

Abahlaziyi be-Ultrasonic Impladance banokusetshenziswa okuhlukahlukene. Umsebenzi wabo oyisisekelo ukunquma izakhiwo zezinto ezibonakalayo noma ukuthola iziphambeko ngokusebenzisa umehluko wokuphazamiseka kwe-acoustic. Izicelo ezijwayelekile zifaka:
● Izinto ezibonakalayo R & D: Ukulinganisa i-acoustic ukungcola kwezinsimbi, ubumba, kanye nezinto zokwenziwa okuhlanganisiwe kusiza ukwandisa ukwakhiwa kwezinto ezibonakalayo kanye namasu wokucubungula.
● Ukuhlolwa okungahambi kahle: Ukuthola iziphambeko ezifana nemifantu, ama-bubble, kanye nokuhlekisa ngaphakathi kwezinto zokwakha. Lapho impahla inesici, ukungcola kwe-acoustic endaweni yokuphekela kuhluke kakhulu kusuka kuleyo ndawo ejwayelekile, futhi ithuluzi lingathola lolu shintsho.
● Ukuhlolwa kwensiza: Kusetshenziselwa ukulinganiswa kokusebenza kwamadivayisi we-acoustic afana nezinzwa ze-ultrasonic, ama-transcuduc kanye nezinketho ze-ultrasonic ukuqinisekisa ukuthi i-acoustic inverdance yazo ehambelana nezidingo zokwakheka.
● I-Biomedical: Emkhakheni wezokwelapha, ingasetshenziselwa ukuhlaziya izakhiwo zezicubu, ngokwesibonelo, ukusiza ukunquma ubukhulu bethambo noma impilo yezicubu ezithambile.

Amapharamitha asemqoka wezobuchwepheshe

Lapho ukhetha noma usebenzisa leli thuluzi, naka amapharamitha asemqoka alandelayo, athinta ngqo ukulinganisa ukulinganisa nokusebenza:
● Ukulinganisa imvamisa uhla: imvamisa ihlanganisa i-khz iye e-MHZ ebangeni le-MHz, idinga ukuqhathanisa amabhande ajwayelekile ezihlakalo ezihlukile (isb.
● Uhla lokulinganisa lokuvimbela: Kukalwa kuma-rayles, leli banga kufanele lifane nokuvinjwa kwezinto ezisetshenziswayo (e.g., cishe ama-413 rayle for air futhi acishe abe ngu-10 ^ 7
● Ukunemba nokuphindaphinda: Ukunemba okuphezulu kukhulisa ukuthembeka kwedatha; Ukuphindaphinda kuqinisekisa ukuvumelana kwezilinganiso eziningi.
● Uhlobo lwe-PROBE: Khetha kususelwa kwindlela yokulinganisa (ukuboniswa noma ukuhambisa). Ukuboniswa kulungele amasampula ngokufinyelela ohlangothini olulodwa, ngenkathi ukuhambisa kudinga ukufinyelela ezinhlangothini zombili.
