Txoj kev ntawm cov hlau tensile xeem thiab nws cov kev ntsuas tsis

TENSILE TEST NTAWM COV KHOOM HLAU COV NTAUB NTAWV Cov Ntaub Ntawv Ntsuas Cov Qauv Ntsuas:
Kev siv cov ntaub ntawv ntsuas tensile tuaj yeem txiav txim siab cov cuab yeej siv cov khoom siv yooj yim, muaj zog, ua kom muaj zog, pailation, elongation, elongation, ntu shrinkage thiab lwm yam.
Tensile xeem qauv ua:
Cov hlau tensile feem ntau yog cov txheej txheem los ntawm cov duab thiab qhov loj me, cov duab thiab lwm yam duab, siv ib qho ntau yog siv puag ncig thiab duab plaub.
Qhov ntsuas tau tseem ceeb:
1, tawm lub zog: thaum cov khoom siv hlau qhia tawm qhov tshwm sim, qhov kev ntxhov siab uas tau mus txog cov khoom siv yas kom tsis muaj kev nce ntxiv hauv kev thauj khoom. Thaum cov khoom ntsuas ntsuas tsis pom tseeb, cov khoom tsim los tsim 0. 2% seem ntawm kev ntxhov siab rau nws cov txiaj ntsig.
2, tensile lub zog: hnoos qeev kom raug rau sab nraud rog (tom qab cov qoob loo rau sab nraud (tom qab cov qoob loo tawm) hauv cov txheej txheem ntawm cov kev ntxhov siab loj. Lub zog tensile sib txawv cov khoom hauv lub zog tensile tuaj yeem tiv thaiv kev ntxhov siab loj, qhov tseem ceeb ntawm lub cev yog tias nws muaj kev cuam tshuam loj deformation tiv thaiv. Lub zog tensile yog lub hauv paus rau nkig hlau xaiv.
3, elongation thiab ntu shrinkage:
Tom qab tawg elongation: tus thawj cim kev deb ntawm lub elongation thiab qhov feem pua ​​ntawm qhov kev xaiv tus thawj.
Tshooj Shrinkage: Necking ntawm qhov chaw hla ntawm qhov chaw loj ntawm qhov loj me thiab qhov feem pua ​​ntawm cov chaw hla kev qub.
4, Modulus ntawm elasticity: cov khoom nyob hauv theem tseem ceeb, piv txwv li kev ntxhov siab thiab txoj cai sib faib) coefficient hu ua modulus ntawm elasticity. Modulus ntawm elasticity tuaj yeem raug suav tias yog kev ntsuas ntawm cov khoom muaj kev ntxhov siab ntawm qhov ntsuas, yog li ntawd, qhov ntau dua cov nyiaj nyuaj, tsis muaj kev ntxhov siab ntawm qhov me. Nws yog qhov taw qhia ntawm lub peev xwm ntawm cov khoom uas los tiv thaiv ywj kev.
