I. Kev Npaj Ua ntej Calibration
Cov cuab yeej npe: tooj liab zoo-tuning teeb ntsia hlau, siab-precision digital vernier calliper, txheem ntsuas ntsuas thaiv, thiab Qib 0 feeler gauge. Xws li cov ntaub ntawv tau txais cov tswv tsev computer.
Yam yuavtsum tau kawm uantej: Lub tshuab kub khiav yuav tsum tau txias tag rau hauv chav tsev kub (25 degree). Lub sensor yuav tsum tau fastened thiab ntsia rau hauv nws qhov chaw. Txhawm rau lav lub teeb pom kev zoo ib yam, qhib lub cuab yeej thiab tso cai rau nws kom sov li 15 feeb.
II. Txias-State Ob-Point Basic Calibration
Zero-point Calibration: Siv lub siab rau lub phaj kub khiav kom ua tiav nws txoj haujlwm xoom pib. Paub meej tias lub sensor sojntsuam yog tag nrho nrog lub phaj kub khiav tsis muaj qhov khoob los ntawm kev siv lub ntsuas ntsuas ntsuas. Nyob rau hauv lub host computer, kho tus nqi tam sim no hloov mus rau 0mm.
Tag Nrho -scale Calibration: Muab tus qauv ntsuas ntsuas ntsuas nruab nrab ntawm cov phaj kub khiav thiab cov ntsuas ntsuas ntsuas. Lub ntsuas ntsuas lub thickness yuav tsum sib haum mus rau lub sensor lub predetermined tag nrho -scale displacement tus nqi. Kho tus nqi tso zis tam sim no rau tus qauv ntsuas ntsuas qhov tuab hauv lub tshuab computer.
Linearity Verification: Xaiv peb lub ntsiab lus nruab nrab uas sib npaug sib npaug ntawm 0 thiab tag nrho cov nplai. Siv lub ntsuas ntsuas ntsuas ntsuas los sib piv cov ntsuas qhov ntsuas qhov ntsuas qhov ntsuas nrog qhov ntsuas qhov ntsuas qhov hloov pauv. Xyuas kom tseeb tias qhov kev ua yuam kev linearity tsawg dua lossis sib npaug li 0.1 hli. Kho qhov xoom taw tes thiab tag nrho scale coefficients yog tias tus nqi tshaj qhov ntau.
III. Kub Dynamic Calibration: Pib lub segmented cua sov qhov kev pab cuam ntawm tus kub khiav, nce qhov kub ntawm 50℃txhua 30 feeb. Nyob rau tib lub sijhawm, sau cov ntsuas kev hloov pauv qhov tseem ceeb ntawm lub sensor ntawm ntau qhov chaw kub.
Sib piv cov ntsuas qhov ntsuas nrog qhov theoretically xam tus nqi ntawm thermal expansion, ΔL=L × × ΔT. Zoo- kho lub sensor lub coaxiality kom tshem tawm cov kev ua yuam kev uas tshwm sim los ntawm installation misalignment yog qhov sib txawv tshaj 0.2 hli.
Tuav lub sensor tso zis tso tawm tus nqi rau ib teev tom qab cua sov rau qhov kev khiav hauj lwm kub kom paub tseeb tias nws yog ruaj khov thiab drift -dawb, nrog xoom drift tswj nyob rau hauv 0.05mm.
IV. Tswb Threshold Calibration
Kho qhov hloov pauv tshaj - txwv lub tswb ceeb toom raws li qhov kev nyab xeeb nthuav dav tshem tawm tau teev tseg hauv tus qauv kub khiav. Txhawm rau pib ceeb toom ntxov, qhov pib raug tsim los ntawm 90% ntawm kev nyab xeeb kev nyab xeeb.
Paub meej tias lub kaw lus tuaj yeem ua rau lub tswb nrov uas twb muaj lawm thiab pom qhov muag tsis pub dhau 1 thib ob thiab ib txhij tso tawm cov lus ceeb toom cuam tshuam rau lub ntsuas kub tswj qhov system los ntawm manually simulating qhov kev hloov pauv yuam kev.
V. Kev txheeb xyuas ntawm Post-Calibration
Paub meej tias qhov ntsuas qhov ua yuam kev rov ua dua yog tsawg dua lossis sib npaug ntawm 0.05mm thiab tsis muaj cov ntaub ntawv hla lossis ploj tom qab peb sib law liag tag nrho -stroke rau pem hauv ntej thiab thim rov qab kev sim..
Tsim ib daim ntawv qhia calibration los ntawm sau tag nrho cov ntaub ntawv calibration. Tom qab ntawd, nws yog ib qho tsim nyog yuav tsum tau ua kom rov ua kom rov zoo dua txhua peb lub hlis kom lav qhov tseeb ntawm kev saib xyuas lub sijhawm ntev.
Cov txheej txheem calibration no tau tag nrho nrog cov nqi qis -Hall effect displacement sensor uas koj tau xaiv rau kev tsim khoom hauv tsev. Nws tuaj yeem ua tiav sai sai ntawm - qhov chaw hauv qhov chaw txhaj tshuaj molding rhiav thiab tsis tas yuav tsum muaj cov cuab yeej ua haujlwm zoo tshaj plaws.
