Lub siab - cov lus teb siab siab rau kev kuaj lub siab zoo hloov kho, nrog cov kev siv dav hauv aerospace, tsheb tshuab, lub zog thiab kev saib xyuas lub zog. Tsis zoo li ib txwm heftors, nws ntaKev teb zoo heev, Qhov dav ntau zaus band, thiabsiab rhiab, enable tiag tiag - lub sijhawm ntes ntawm kev hloov siab sai sai. Yog li, nws tau dhau los ua cov cuab yeej tseem ceeb rau kev ntsuas siab nyob rau hauv high- muaj ib puag ncig muaj zog. Hauv tsab xov xwm no, peb yuav piav qhia meej txog nws cov ntsiab cai ua hauj lwm, thiab cov ntawv thov raug nyob hauv ntau daim duab ua piv txwv thiab kev ua haujlwm ntawm kev ntsuas.
Ua Haujlwm Cov Ntsiab Cai
High - zaus teb siab siab cov ntsiab lus siab ib txwm ua haujlwm raws li covPiezoelectric nyhuvCov. Piezoelectric cov ntaub ntawv (xws li quartz thiab pzt ceramics) tsim hluav taws xob cov nqi raws cov lus qhia tshwj xeeb thaum raug rau sab nraud. Kev txuam nrog cov nqi no yog sib npaug rau cov kev thov nias. Vim tias cov lus teb sai sai dynamic muaj peev xwm ntawm cov efficzoelectric, xws sensors tuaj yeem ceev ceev siab hloov cov paib.
Cov kev sib raug zoo ntawm cov zis them ntawm cov ntaub ntawv piezoelectric thiab lub zog tuaj yeem qhia los ntawm cov qauv:Q = d × F (Q
Cov mis no qhia tau tias tus nqi tsim tau nce ntxiv raws li lub zog thov nce.
Txij li thaum lub npe cov cim uas tau ua los ntawm cov khoom siv tsis muaj zog heev, lub siab {} {impedance amplities ampleger amplay mus rau hauv cov cim hluav taws xob ntsuas. Kev Hloov Siab Tshaj Tawm Tseem Ceeb Tshaj kom muaj kev lim tawm qis- zaus suab nrov thiab khaws cov paib siab hloov cov paib.
Hauv kev xyaum, cov teeb hluav taws xob qaug hluav taws xob tso zis tawm los ntawm lub piezoelectric sensor yog thawj cov lus qhia rau lub prepplifier nrog cov tswv yim tawm tswv yim siab. Tomqab kev hloov dua siab tshiab, cov teeb liab tuaj yeem ua ntxiv los ntawm kev ua kom zoo dua los ntawm kev ua kom dav dav thiab nrhiav tau cov voj voog ua ntej tau ua raws li cov twj kaw neeg lossis cov ntaub ntawv kaw cia. Qhov tseem ceeb ntawm kev ntsuas lub voj voos lus dag hauv lub preamplifier nrog cov tswv yim tawm tswv yim zoo, uas ua haujlwm rau ob lub luag haujlwm tseem ceeb:
Converting the high-impedance output of the sensor to a low-impedance output;
Amplifying Hluav Taws Xob Hluav Taws Xob hluav taws xob los ntawm lub sensor.
PEAMPLIERS muaj ob qho kev teeb tsa Circuit Court sib koom tes:
·Voltage amplifiers nrog cov lus qhia tseem ceeb: lawv cov zis hluav taws xob yog ib feem ntawm cov tswv yim voltage (piv txwv li, lub sensor cov zis);
·Kev tsim kho lub capactor: lawv cov zis hluav taws xob yog sib npaug rau cov nqi ntxiv.
Tshwj xeeb, muaj kev cuam tshuam ntawm cable ntev variation rau kev coj ua amplifiers yog negligible. Qhov txiaj ntsig no tau ua rau nce ntxiv daim ntawv thov kev ua kom zoo tshaj plaws.
Raws li pom nyob rau hauv lub cim sib npaug ntawm lub piezoelectric sensor txuas nrog lub voj voog Circuit Court (Daim duab (daim duab sib npaug ntawm cov duab hluav taws xob ua tau zoo tshaj plaws {{zaus teb. Txawm li cas los xij, thaum lub zog ua yeeb yam ntawm lub piezoelectric keeb yog zoo li qub, cov zis hluav taws xob ntawm cov lus tawm ntawm lub zog thiab cov dej ntws tawm ntawm lub sensor nws tus kheej. Yog li ntawd, piezoelrictric sensors tsis tuaj yeem siv rau kev ntsuas lub zog zoo li qub. Nws tseem yog ib qho tseem ceeb kom nco ntsoov tias kev sib txuas cable nruab nrab ntawm lub piezoelectric sensor thiab cov piefflifier tsis tuaj yeem hloov tsis tau, lwm yam ntsuas tsis raug yuav raug qhia.
Daim duab saum toj no qhia tau cov nqi hluav taws xob amplifier, uas feem ntau siv raws li cov tswv yim hluav taws xob ntawm lub piezoelectric sensor. Nws muaj cov lus pom zoo thiab lub siab- Tau txais kev ua haujlwm zoo tshaj plaws. Theoretical suav qhia tias txawm tias qhov txuas txuas cable ntev tshaj 100 metres, qhov rhiab heev ingpifier tsis tau hloov pauv tsis tau} Qhov no yog nws cov npe nrov tshaj plaws.
Piezoelrictric sensors muaj cov tsis zoo linearity thaum ntsuas qhov kev ntsuas tsis tshua muaj kev sib kis, feem ntau yog vim tus tsis muaj kev sib kis, feem ntau yog vim tus tsis muaj zog ntawm lub zog hluav taws xob {{cov kabmob. Txhawm rau hais txog qhov no, ib lub zog (Prestressed Qhov no tsis tsuas yog tshem tawm cov tsis muaj tseeb nyob rau hauv qis - papt} Kev thov sib chwv ntawm sab hauv thiab sab nraud ntawm sensor thiab txhim kho rigidity. Tshwj xeeb, lub tshuab ntsuas hluav taws xob tsuas yog ntsuas cov quab yuam tensile, hloov nrees - compression quab yuam, shear zog, thiab torque tom qab teloading.
Qauv qauv tsim
Tus qauv tsim ntawm siab - zaus teb siab sensors yuav tsum tau ua kom tau raws li qhov yuav tsum tau ua kom muaj kev ntsuas siab thiab siab} precision dynasaral ntsuas. Lawv cov qauv feem ntau suav nrog cov ntsiab lus hauv qab no:
Piezoelectric caij: Raws li cov ntsiab lus tseem ceeb, nws yog feem ntau yog ua los ntawm cov ntaub ntawv nrog cov lus teb ceev thiab zoo thermal stability, xws li quartz lossis pzt ceramics. Nws cov duab tuaj yeem yog cylindrical, ntawv - zoo li, lossis conical, nyob ntawm cov kev thov muab teev tshwj xeeb.
Neeg kho tshuab kis tiv thaiv: Cov teeb liab siab feem ntau kis tau rau lub piezoelectric kis los ntawm cov neeg kho tshuab kis (xws li diaphragms lossis txheej txheem cais). Cov feem no yuav tsum muaj kev kub ntxhov thiab tsis ntev los ua kom muaj kev sib kis uas tsis muaj qhov sib kis ntawm qhov siab ntawm- zaus siab.
Tsev nyob: Lub tsev sensor feem ntau yog ua los ntawm cov ntaub ntawv hlau (xws li cov hlau hlau lossis titanium alloy) kom hloov kho cov chaw hnyav. Nws yuav tsum muaj kev sib khi tau zoo los tiv thaiv kev cuam tshuam los ntawm lwm qhov (xws li ya raws lossis cov roj corrosive) ntawm lub ntsuas kev ua haujlwm.
Cov Hlau Hlau: Cov paib zis feem ntau siv coaxial clesles lossis micro txuas rau kom muaj teeb liab kev ncaj ncees thiab anti {}}} kev cuam tshuam muaj peev xwm.
