Momwe Wrench ya Digital Torque Imagwirira ntchito: Kuchokera ku Sensor mpaka Kuwonetsa

Ma torque a digito amayezera ma torque pakompyuta ndikuwonetsa zotsatira zake pazenera. M'mapangidwe amtundu wokhazikika, kukweza wrench kumapangitsa kuti pakhale kasinthasintha kakang'ono ka zinthu zomveka. Ma geji a strain amayankha kusinthika kumeneku, ndikupanga chizindikiro chamagetsi kuti zinthu zamagetsi zizikhala, kusinthana ndikusintha kukhala kuwerenga kwa torque. Chiwonetsero ndi gawo lomaliza la ndondomekoyi. Kukonzekera kwake, kuwerenga kwamoyo komanso kusungidwa kwapamwamba kumatha kufotokozera zinthu zosiyanasiyana, kotero kumvetsetsa komwe mtengo uliwonse umachokera kumathandiza kufotokoza zomwe chida chikuwonetsa.

Momwe Ma Torque Amagwiritsidwira Ntchito Imapanga Chizindikiro cha Sensor

Elastic Deformation M'kati mwa Chida

Kugwiritsa ntchito mphamvu pa chogwirira kumapanga torque pa axis ya fastener. Mkati mwa wrench, katunduyo amatulutsanso kapindika kakang'ono kamene kamanyamulira. Chomverera chapangidwa kuti chiziyankha modziwikiratu mkati mwa momwe chimagwirira ntchito, kulola chida kuti chigwirizane ndi kuyankhidwa kwake ndi torque yomwe yagwiritsidwa ntchito.

Uku ndikusinthika kwa elasticity: chinthucho chimakonda kubwerera ku mawonekedwe ake pomwe katunduyo achotsedwa. Izi sizikutanthauza kuti wrench iyenera kupindika mowonekera. Kuyenda kofunikira pakuyezera kungakhale kochepa kwambiri kuti musawone.

Kukonzekera kwa makina kumasiyana pakati pa mapangidwe. Sensa imatha kuyankha kupindika kapena kugwedezeka, kutengera momwe chida chimanyamulira ndikuzindikira katundu. Kuyika kwa ma sensing ndi gauge kumatsata kapangidwe ka makina.

Momwe Strain Gauge Imazindikirira Kusinthako

Choyezera cholumikizira chimasintha mphamvu yamagetsi pamene pamwamba pake imatambasuka kapena kukanikiza. Kukonza ma geji mumayendedwe a mlatho kumathandizira kuti magetsi azitha kuzindikira kusintha kwakung'ono ngati kusiyanasiyana kwamagetsi.

Kutulutsa kwa mlatho kumasintha ndi katundu pa sensing element. Poyesa yankho limenelo, zamagetsi zimatha kutsata torque yomwe ikugwiritsidwa ntchito. Kuyeza komweko sikufuna cholozera kapena kusuntha kowoneka kuti kuwonetse kusintha.

Panthawiyi, chidacho chimakhala ndi mphamvu yamagetsi pakukweza. Palibe nambala yomaliza yosonyezedwa mu N·m.

Momwe Zamagetsi Zimasinthira Chizindikiro Kukhala Digital Data

Kusangalatsa kwa Bridge, Kukulitsa ndi Kusefa

Sensa yokhazikitsidwa ndi mlatho imafunikira kusangalatsa kwamagetsi kuti kusintha kwake kutheke kutulutsa kutulutsa koyezera. Chizindikiro chotsatira chiyenera kukhala choyenera pa gawo lotsatira la dongosolo la kuyeza.

Kukulitsa kumabweretsa chizindikiro chaching'ono munjira yothandiza poyezera. Kusefa kumathandiza kulamulira zigawo zosafunika za chizindikiro, monga phokoso lamagetsi, zomwe zingasokoneze zotsatira zake. Pamodzi ndi chisangalalo, izi zimakonzekeretsa sensa linanena bungwe kutembenuka.

Awa ndi magawo ogwirira ntchito, osati magawo olekanitsa pa board board. Zida zina zimaphatikiza ntchito zingapo mkati mwa dera lophatikizika. Kukhazikitsa kwawo kumaphatikizanso kusankha pa liwiro la kuyankha ndi phokoso, kotero chiwonetsero chomveka chokha sichiwulula momwe zida zamagetsi zoyambira zimasinthira katundu.

Kusintha kwa Analogi kupita Pa digito

Analogi-to-digital converter, kapena ADC, imayimira chizindikiro chamagetsi chokhazikika ngati chiwerengero cha nambala. Purosesa imatha kugwiritsa ntchito zomwezi kuwerengera mtengo wa torque ndikuwongolera zowonetsera.

Digitization imapangitsa kuti muyeso upezeke pokonza manambala. Chidacho chitha kugwiritsa ntchito miyeso yotsatizana kuti isinthe mawonekedwe amoyo, kusunga nsonga yoyezera kapena kufananiza kuwerenga ndi chandamale chomwe mwasankha. The converter amapereka deta; kukonza kumatsimikizira momwe detayo imagwiritsidwira ntchito.

Momwe Digital Data Imakhalira Kuwerenga kwa Torque

Kugwirizana ndi Kutulutsa kwa Sensor ku Torque Yodziwika

Kutulutsa kwa chosinthira sichofunika kwenikweni mu newton-metres. Dongosolo loyezera lophatikizidwa limafunikira mgwirizano pakati pa kuyankha kwake kwamagetsi ndi torque yodziwika.

Ubale umenewo umalola chida kumasulira kusintha kwa sensa kutulutsa kusintha kwa torque yomwe ikuwonetsedwa. Calibration imafananiza zisonyezo za chidacho ndi ziwerengero zomwe zimatchulidwa. Pamene kusintha kuli kofunika, ndizochitika zosiyana; kungoyesa kokha sikungokonza chida.

Kutembenuka kungagwiritse ntchito ma coefficients osungidwa kapena makonzedwe ena oyenerana ndi mapangidwewo. Zirizonse zomwe zakhazikitsidwa, ubalewu umagwira ntchito ku dongosolo lonse la kuyeza, kuyambira pa chinthu chonyamulidwa mpaka pachiwonetsero. Kuwerengera kosinthira kosasinthika kumakhala kothandiza pokhapokha ngati kukugwirizana ndi kuchuluka komwe akuyezedwa.

Zero Offset ndi Engineering Units

Dongosolo loyezera litha kukhala ndi chotsitsa: kutulutsa kosawerengeka ngakhale katundu woyezedwa ndi zero. Ntchito yowerengera zero imakhazikitsa zomwe zimagwiritsidwa ntchito powerenga motsatira, kutsatira malangizo a chida.

Zeroing ndi ma calibration amayankha mafunso osiyanasiyana. Kukhazikitsa ziro yotsitsidwa sikuwonetsa kuti chidacho chimawerengedwa bwino pama torque ake onse. Offset amafotokoza cholakwika poyambira; phindu limafotokoza kukula kwa yankho. Kuwongolera poyambira pakokha sikukhazikitsa ubale pakati pa nthawi yoyezera.

Chidacho chikatsimikizira torque, imatha kuwonetsa kuchuluka kwake mugawo lothandizira monga N·m kapena ft·lb. Kusintha unit kumasintha chiwerengero cha chiwerengero cha kuchuluka. Sichimapanga torque yosiyana yakuthupi pamgwirizano.

Zomwe Chiwonetserocho Chimawonetsa Panthawi ndi Pambuyo Kulimbitsa

Torque Yamoyo, Peak Torque ndi Kukhazikitsa Chandamale

Chotsatira chandamale ndi mtengo womwe walowetsedwa kuti agwire ntchito. Kuwerenga kwamoyo kumayimira torque yoyezedwa pamene katundu akusintha. Kuwerenga pachimake kumasunga mtengo woyezera kwambiri womwe umatengedwa panthawi yoyezera yomwe chida.

Mfundo zimenezi zimagwira ntchito zosiyanasiyana. Cholingacho chimauza wogwiritsa ntchito mtengo womwe wasankhidwa; si umboni kuti torque iyi idagwiritsidwa ntchito kale. Chiwongola dzanja chosungidwa chikhoza kuwonekabe mphamvu ikachepetsedwa, pomwe chiwonetsero chotsatira chikutsatira muyeso wosinthika.

InuBar wrench ya digito ya ratchet imatchula mitundu ya PEAK ndi TRACK, P0-P9 torque presets, ndi zidziwitso zomveka komanso zowoneka bwino. Izi zikufotokozera momwe chida chimaperekera komanso kugwiritsa ntchito zidziwitso zoyezera. Chenjezo sichiyenera kutanthauziridwa ngati kuyimitsidwa kodziwikiratu.

Mukamawerenga za YouBar digito torque wrench range, fananizani ndi zomwe zikuwonetsedwa ndi zomwe mukufuna. Pazofunikira zomwe zimapitilira zomwe zasindikizidwa, kambiranani za muyeso ndi zowonetsera zachitsanzo china.
