Portable Ultrasonic Impedance Ntsuas Analysis

Portable Ultrasonic Impedance Ntsuas Analysis

Kev piav qhia:

Kev ntsuas kev ntsuas, qhov tseem ceeb yog daim ntawv tso cai, logarithmic teeb ntawm ob lub graphics (ob lub duab yog qhov tseem ceeb ntawm kev tsim nyog tsim nyog), thiab ntau tshaj li ib lub teb tsis muaj: resonance zaus Fs, qhov ua siab tshaj plaws Gmax, bandwidth F2 F1, qhov zoo tshaj plaws Qm, dawb tsis muaj peev xwm CT, dynamic tsis kam R1, dynamic inductance L1, dynamic capacitance C1, static capacitance C0, zoo electromechanical coupling coefficient Keff.
Kev ntsuas ntsuas tau yooj yim dua thiab yooj yim dua, kuj muaj ntau lub sij hawm ntau cov cuab yeej los ntawm Agilent / HP, xws li: HP Impedance Gain-Phase Analyzer 4294A, Agilent E5100A, Network Analyzer, HP 3563A, Control System Analyzer thiab lwm yam Nws kuj yog ib qho yooj yim los siv HS520A (los ntawm cov kws tsim khoom lossis cov neeg ua haujlwm rau cov neeg ua haujlwm).
HS520A yog le HS70A thiab HS80A, ib tiam tshiab ntawm cov Cheeb Tsam Cheeb Tsam Ultrasonic.

Peb cov khoom muaj plaub qhov zoo tshaj plaws

Cov cuab yeej twv yog qhov tseem ceeb tshaj plaws ntawm cov khoom tshev khoom zoo, yog li qhov khoom ntawm "credibility" tseem ceeb heev. Peb cov khoom muaj plaub qhov zoo tshaj plaws:

1. Tsinghua University thiab Suav Academy ntawm Sciences Lub Tsev Kawm Ntawv ntawm Acoustics koom tes tsim technology.

     2. Txij li thaum xyoo 2001, peb cov HS60A / 70A series ntawm cov khoom muag mus rau kev ua lag luam tau 15 xyoo, txhiab tus neeg siv nyob rau hauv txoj kev ua lag luam, tau rais los ua qhov tseeb ntawm kev ntsuas kev lag luam hauv ultrasound.

3. Tau ntau tshaj li ntawm 15 lub xyoos dhau los, ntau tshaj 200 lub tsev kawm ntawv tau siv peb cov twj, vim lawv feem ntau muaj ntau tshaj li 20,000 ntawm cov twj paj nruag, 4294A. Peb lub twj paj nruag tau raug kuaj ntau lub sij hawm nrog Txawv Agilent instruments. Nws hloov tawm tias cov txiaj ntsig ntawm peb lub twj paj nruag yog kev ncaj ncees.

4. Peb lub twj paj nruag tau siv los ntawm ntau lub German thiab US ultrasonic xeem cov tuam txhab uas muag ua cov khoom seev cev. Qhov ntsuas yog tus yuam sij rau kev tswj kom zoo.

Kev Qhia:

Cov ntawv thov:
Piezoelectric ceramics, transducers, ultrasonic tu cav tov, ultrasonic yas vuam tshuab, underwater acoustic, magnetostrictive ntaub ntawv, ultrasonic li., Ultrasonic atomization, reversing radar, ultrasonic li, phacoemulsification, ultrasonic motors, thiab lwm yam li siv piezoelectric thiab ultrasound.

Ultrasonic HS 520A caij analyzer yuav muab cov duab cim nram qab no:

1) qhov kev tso npe ntawm GBF coordinate curve:
Rau txoj kab laug sab: abscissa - nkag qhov tiag tiag G, ordinate - admitance imaginary part B
Ntawm sab xis ntawm qhov nkhaus: liab - nkag qhov tiag G, xiav - nkag fab xav hauv seem B, qhov feem pua

2) Kev sib koom tes nruab nrab RXF coordinate curve:

Lem nkhaus: Abscissa - Empedance qhov tiag tiag R, Abscissa - Impedance fab xav hauv siab X

Txoj Kev Ntaus Laj: Liab - Huv Zem Xeem R, Xiav - Kev Xeem Impedance X, Ntsug - Zaus

3) impedance ntawm txoj kev tswj hwm txoj kev sib txawv hauv lub ZOP (ZθF coordinate curve):

Liab - impedance hom | Z |, xiav - xaj hluav taws xob, theem - zaus

4) Txoj kev nkag tebchaws Ncig Tebchaws txoj kev tswjhwm Yi-

Liab - kev nkag tuaj hom | Y |, xiav - xaj qhua, rhais - zaus

5) Qhov kev sib txuas lus ntawm qhov chaw logarithmic:

Lem nkhaus: abscissa - admittance real part G, ordinate - admitance fab xav hauv siab B

Txoj Kev Nkag Siab: Liab - Logarithm ntawm Impedance Modulus Lg | Z |, Xiav - Xeem Zaj, Ntsug - Zaus
