Lub cev hnyav transducer yog ib qho khoom siv uas hloov lub zog siv los ntawm ib daim ntawv mus rau lwm qhov. Lub xovtooj ntawm tes kuj yog qhov nro thiab lub siab sensor, uas hloov lub zog siv rau lub xovtooj ntawm tes mus rau hauv lub ntsuas hluav taws xob ntsuas hluav taws xob thiab tso tawm rau ntawm cov khoom ntsuas. Yog li ntawd, lub load cell, zoo li lwm yam sensors, yuav tsum tau siv ua ke nrog cov zaub ntsuas.
Tam sim no, feem ntau siv hom khoom hnyav hauv I kev lag luam daim ntawv thov yog qhov ntsuas ntsuas hom load cell. Lub strain gauge load cell kuj shortens thiab thickens lub strain gauge thaum nws raug quab yuam. Qhov no, nyob rau hauv lem, ua rau qhov tsis kam ntawm lub strain gauge hloov, uas tuaj yeem hloov mus rau hauv qhov ntsuas tus nqi zog.
Rau qhov hloov pauv voltage thiab cov zis tso tawm rau ntawm lub 'meter', vim qhov kev hloov pauv ntawm cov zis yog proportional rau tus nqi ntawm qhov hnyav, qhov hnyav ntawm cov khoom tuaj yeem txiav txim siab los ntawm qhov hloov pauv voltage.
Cia peb tham txog lub hauv paus ntsiab lus ntawm kev ua hauj lwm kom meej: lub elastic lub cev ntawm lub load cell yog elastically deformed nyob rau hauv qhov kev txiav txim ntawm sab nraud quab yuam kom cov kuj strain gauge pasted rau nws nto kuj deformed. Tom qab qhov ntsuas qhov ntsuas qhov ntsuas tau deformed, nws cov nqi kuj yuav tshwm sim. Hloov pauv, thiab tom qab ntawd hloov qhov kev hloov pauv no mus rau hauv lub teeb liab hluav taws xob los ntawm kev ntsuas ntsuas hluav taws xob, yog li ua tiav cov txheej txheem ntawm kev hloov lub zog sab nraud rau hauv lub teeb liab hluav taws xob. Nws tuaj yeem pom tau tias qhov kev kuaj xyuas Circuit Court, lub cev elastic thiab qhov ntsuas qhov ntsuas qhov ntsuas yog qhov tseem ceeb ntawm qhov kev tiv thaiv kab mob load cell.
Tom qab ntawd peb yuav piav qhia txog lub hauv paus ntsiab lus ntawm lub xov tooj ntawm tes thiab peb lub ntsiab lus ntawm nws lub cev muaj pes tsawg leeg, uas yog [nrhiav Circuit Court ( kis tau tus mob cable), elastic lub cev thiab tiv thaiv kab mob ntsuas]:
1. Kev kuaj xyuas Circuit Court (hloov cable)
Lub luag haujlwm ntawm kev kuaj xyuas Circuit Court yog los hloov qhov kev hloov pauv ntawm qhov ntsuas qhov ntsuas tsis kam mus rau hauv qhov hluav taws xob tso tawm. Vim tias tus choj Wheatstone muaj ntau yam zoo, xws li nws tuaj yeem cuam tshuam qhov cuam tshuam ntawm qhov kub thiab txias, nws tuaj yeem cuam tshuam kev cuam tshuam ntawm lub zog sab nraud, thiab nws tuaj yeem yooj yim daws cov teeb meem them nyiaj ntawm lub xov tooj ntawm tes.
Stern txuas hniav yog dav siv nyob rau hauv load cells. Vim tias tag nrho - choj sib npaug- caj npab choj muaj qhov siab tshaj plaws, qhov tsis sib xws ntawm txhua caj npab yog tib yam, thiab kev cuam tshuam ntawm ntau yam kev cuam tshuam tuaj yeem yooj yim tshem tawm ib leeg, yog li cov kab hluav taws xob tag nrho siv tag nrho - choj sib npaug - caj npab.
2. Elastomers
Ib qho elastomer yog - cov tswv cuab nrog cov qauv tshwj xeeb. Nws muaj ob txoj haujlwm. Thawj yog tias nws dais lub zog sab nraud ntawm lub xov tooj ntawm tes, tsim cov tshuaj tiv thaiv rau sab nraud quab yuam, thiab ua tiav cov txiaj ntsig zoo li qub; kev thab plaub, nws yuav tsum tsim kom muaj - zoo strain teb, thiaj li hais tias tus Resistance strain gauge
Nws yog qhov zoo tshaj plaws los ua kom tiav txoj haujlwm hloov dua siab tshiab ntawm jujube hluav taws xob teeb liab.
3. Resistance strain gauge
Ib qho kev ntsuas kev tiv thaiv kab mob yog ib qho kev tiv thaiv xaim mechanically faib rau ntawm lub substrate ua los ntawm cov khoom siv organic, uas yog, qhov ntsuas ntsuas. Ib qho ntawm nws qhov tseem ceeb tsis yog qhov rhiab heev coefficient K. Thaum nws ob qhov kawg raug rau F quab yuam, nws yuav elongate, uas yog hais tias, deform. Cia nws elongated, nws transverse
Tus ntoo khaub lig-sectional cheeb tsam raug txo, uas yog, nws tus ntoo khaub lig-sectional vojvoog vojvoog yog txo. Kev sib piv ntawm qhov kev hloov pauv ntawm qhov kev hloov pauv (tus txheeb ze hloov hauv qhov tsis kam) ntawm qhov ntsuas qhov ntsuas qhov tsis kam thiab qhov elongation tus nqi (tus txheeb ze hloov qhov ntev) ntawm cov hlau tsis kam. Nws yuav tsum tau muab sau tseg tias qhov luaj li cas ntawm rhiab heev coefficient K tus nqi yog txiav txim los ntawm cov khoom ntawm cov hlau kuj hlau.
Ib qho kev txiav txim siab tas li los ntawm qhov xwm txheej, nws tsis muaj dab tsi ua nrog cov duab thiab qhov loj ntawm qhov ntsuas qhov ntsuas. Tus nqi K ntawm cov khoom sib txawv feem ntau yog nyob nruab nrab ntawm 1.7 thiab -3.6; Qhov thib ob, tus nqi K yog qhov tsis muaj qhov ntau, uas yog, nws tsis muaj qhov loj me. Hauv cov khoom siv tshuab, OL / L yog hu ua strain, qhia tias yog ε, thiab nws feem ntau siv los qhia elasticity.
Yog tias nws loj heev, nws tsis yooj yim heev, thiab nws feem ntau siv los ua ib chav tsev ntawm millionths ntawm nws, sau ua uε.
