Cov lus qhia rau kev txhim kho tag nrho cov kev ua tau zoo ntawm txhuas stranded hlau nrog aluminium alloy core

---

Qhov ntsuas tawg quab yuam ntawm tus neeg xyuas pib yog xam raws li lub zog ntawm tag nrho cov aluminium ib kab thiab txhawb nqa. Txawm yog, qhov tseeb braking quab yuam deviates los ntawm qhov tseeb xam tus nqi. Lub ntsiab yog vim li cas rau qhov no yog hais tias lub zog ntawm txhua txhua ib leeg tsis siv tag nrho. Yog li ntawd, Thaum tsim cov khoom lag luam tsis yog tsuas yog ua kom tau raws li qhov yuav tsum tau muaj zog tsawg kawg nkaus xwb tab sis kuj tseem yuav xav txog yuav ua li cas lub zog ntawm txhua lub xov hlau raug kaw.. Tsis yog nws tsuas yog siv tag nrho cov khoom siv, tab sis tag nrho cov kev ua tau zoo ntawm cov hlau kuj yuav zoo heev.

Nrog kev txhim kho txuas ntxiv ntawm lub zog hluav taws xob, ntau yam cov khoom tshiab tau los ua, xws li steel core aluminium strand, aluminium-clad steel tub ntxhais aluminium strand, aluminium-clad steel tub ntxhais aluminium alloy strand, aluminium alloy strand, aluminium alloy core aluminium strand, aluminium-clad steel tub ntxhais kub-resistant aluminium alloy strand, tus lwm yam. Txawm yog, tag nrho tensile kev ua tau zoo yog qhov teeb meem loj hauv kev tsim cov khoom siv nyiaj siv ua haujlwm.

Aluminium alloy core aluminium strand tag nrho cov kev ua tau zoo txhim kho kev txawj ntse

Thawj, los ntawm lub zog, kho cov uniformity ntawm txhua kab.

Txhua kab raws li qhov loj ntawm nws lub zog, qhov degree ntawm kev ntxhov siab-kev coj tus kheej yog txawv. Ib yam li qhov nro sensor muaj qhov zoo tshaj plaws tensile ntau yam, ntau tshaj nws qhov ntau yuav tsis tsuas yog ua rau cov khoom puas tab sis kuj ua rau deviations hauv cov ntaub ntawv. Aluminium ib kab kuj zoo ib yam, qhov sib txawv ntawm lub zog ntawm aluminium ib kab ntawm kev ntxhov siab ntawm cov degree ntawm bearing kuj txawv. Thaum cov kev sib txawv ntawm lub zog ntawm cov kab ib leeg tau tso tseg ua ke, qhov kev ntxhov siab yog uniformly faib rau txhua kab. Lub zog ntawm cov kab ib leeg yuav me me kom nqa cov degree ntawm kev tawg thaum ntxov, thaum lub zog ntawm ib kab yuav tsis ua nws lub luag haujlwm. Yog li ntawd, lub zog ntawm qhov sib txawv heev yog ib qho tseem ceeb parameter los kuaj kev siv cov khoom siv tshuab.

Ib xi nkoos, los ntawm elongation thiab seem txoj kab uas hla piv los kho qhov elongation thiab seem txoj kab uas hla ntawm qhov loj.

Lub elongation ntawm cov hlau hlau ntawm tag nrho cov tensile zog ntawm qhov cuam tshuam kuj zoo heev. Ntau qhov kev sim tau ua pov thawj tias tag nrho lub zog tensile ntawm aluminium clad steel cored aluminium strand yog ib qho yooj yim ua tsis tau qhov tshwm sim.. Lub ntsiab yog vim li cas rau qhov no yog hais tias lub elongation ntawm aluminium-clad steel yog me heev. Aluminium hlau mechanical zog ntawm kev siv tus nqi yog tsawg heev. Thaum lub txhuas hlau raug tso tseg, lub suab me me, qhov zoo dua nws ductility. Qhov siab dua qhov yuav tsum tau elongation ntawm cov hlau hlau. Lub elongation ntawm aluminium-clad steel hlau yog hais txog 1.0, thiab cov aluminium hlau kuj yog hais txog 1.0, ntxiv rau tus nqi ntawm expansion ntawm lub stranded suab, lub elongation ntawm steel hlau yog deb ntawm txaus. Yog li ntawd, cov hlau tsim rau aluminium-clad steel hlau tuaj yeem tsim nyog nce nws qhov sib piv, txo qhov sib txawv ntawm aluminium-clad steel hlau thiab txhuas hlau elongation, thiab ntau ua si rau txhua yam khoom ntawm aluminium hlau. Hauv luv, aluminium hlau elongation + vim lub suab elongation = steel hlau elongation.

Thib peb, los ntawm kev npaj ntawm cov qauv ntawm ib kab, elongation yog ntau dua nyob rau hauv txheej txheej txheej txheej txheej.

Qhov kev sim ua pov thawj tias feem ntau ntawm cov kab ib kab tawg yog tawg nyob rau hauv txheej txheej sab nraud. Lub elongation ntawm txheej txheej sab nraud kuj yog qhov tseem ceeb cuam tshuam rau tag nrho cov braking quab yuam. Thaum lub zog ntawm ib lub xaim yog qhov tseeb, qhov siab dua qhov elongation, qhov siab dua lub zog ntawm ib leeg hlau txhua yam khoom tuaj yeem ua kom tiav.

Feem ntau ntawm cov kev ua tau zoo tam sim no ntawm cov xaim tsis ua tiav tag nrho, cov npoo yog loj, txheej txheem yog txheej txheem ntev ntawm kev txheeb xyuas, xav tau ntau yam kev sim thiab kev txheeb xyuas cov ntaub ntawv, nov yog ib lub tswvyim xwb, hnyav hauv kev xyaum. Hauv luv, hauv kev tsim cov khoom, lub hom phiaj kawg yog nyob rau hauv cov hlau elongation rau 1%, tag nrho cov kab ib leeg tuaj yeem ua si rau qhov zoo tshaj plaws kom qhov kev ua tau zoo ntawm cov hlau yuav ua tau zoo dua qub.
