1. Yield zog ntawmflange
Yog qhov kev txwv ntawm cov khoom siv hlau thaum cov khoom tshwm sim tshwm sim, uas yog, kev ntxhov siab tiv thaiv microplastic deformation. Rau cov khoom siv hlau uas tsis muaj qhov tshwm sim pom tseeb tshwm sim, qhov kev txwv tawm tau txhais tau tias yog qhov kev ntxhov siab ntawm 0.2% residual deformation, uas yog hu ua qhov txwv tsis pub dhau los yog lub zog tawm los.
Lub zog sab nraud ntau dua li lub zog tawm los yuav ua rau cov khoom tsis raug thiab tsis tuaj yeem hloov pauv. Yog tias qhov kev txwv tsis pub muaj cov pa roj carbon tsawg yog 207MPa, thaum ntau dua qhov kev txwv no nyob rau hauv qhov kev txiav txim ntawm sab nraud quab yuam, cov khoom yuav tsim deformation mus tas li, tsawg dua qhov no, cov khoom yuav rov qab zoo li qub.
(1) Rau cov ntaub ntawv uas pom tseeb tawm los tshwm sim, yield zog yog qhov kev ntxhov siab ntawm qhov taw tes tawm (yield tus nqi);
(2) Rau cov ntaub ntawv uas tsis muaj qhov tshwm sim pom tseeb tshwm sim, qhov kev ntxhov siab thaum qhov kev txwv qhov sib txawv ntawm qhov kev sib raug zoo ntawm kev ntxhov siab thiab cov kab mob nce mus txog tus nqi teev tseg (feem ntau yog 0.2% ntawm qhov ntsuas qhov deb). Nws feem ntau yog siv los ntsuas cov khoom siv kho tshuab thiab cov khoom siv ntawm cov khoom siv, thiab yog qhov txwv ntawm kev siv cov khoom siv. Vim tias nyob rau hauv qhov kev ntxhov siab tshaj qhov kev txwv tsis pub dhau ntawm cov khoom siv tom qab lub caj dab, lub zog nce ntxiv, kom cov khoom puas tsuaj, tsis tuaj yeem siv ib txwm. Thaum qhov kev ntxhov siab dhau qhov kev txwv elastic thiab nkag mus rau theem tawm, qhov deformation nce sai, uas ua rau tsis yog elastic deformation tab sis kuj yog ib feem ntawm cov yas deformation. Thaum qhov kev ntxhov siab nce mus txog qhov point B, cov yas strain nce sharply thiab cov kev ntxhov siab-strain fluctuates me ntsis, uas yog hu ua yield. Qhov siab tshaj plaws thiab qhov kev ntxhov siab tsawg kawg nkaus nyob rau theem no yog hu ua Upper yield point thiab qis yield point feem. Txij li thaum tus nqi ntawm qhov qis yield point yog qhov ruaj khov, nws yog hu ua yield point lossis yield zog (ReL lossis Rp0.2) raws li qhov ntsuas ntawm cov khoom tsis kam.
Qee cov hlau (xws li cov pa roj carbon siab) tsis muaj qhov tshwm sim pom tseeb tshwm sim, feem ntau tshwm sim ntawm cov kab yas deformation (0.2%) ntawm kev ntxhov siab raws li lub zog tawm los ntawm cov hlau, lub npe hu ua lub zog yield.

2. Kev txiav txim siab ntawmflangeyield zog
Qhov tshwj xeeb uas tsis yog qhov sib npaug ntawm lub zog elongation los yog qhov seem seem elongation kev ntxhov siab yuav tsum tau ntsuas rau cov khoom siv hlau yam tsis muaj qhov tshwm sim pom tseeb, thaum lub zog tawm los, lub zog tawm los sab saud thiab lub zog qis zog tuaj yeem ntsuas rau cov khoom siv hlau nrog cov txiaj ntsig pom tseeb. Feem ntau, tsuas yog lub zog tawm los ntsuas.
3. flangeyield zog standard
(1) Qhov kev ntxhov siab siab tshaj plaws hauv qhov sib piv txwv kev ntxhov siab-txoj kab nkhaus, uas ua raws li kev sib raug zoo, feem ntau yog sawv cev los ntawm σ P hauv ntiaj teb. Thaum qhov kev ntxhov siab tshaj σ P, cov khoom raug txiav txim siab los tawm. Muaj peb hom kev siv tau zoo tshaj plaws hauv kev tsim kho:
(2) Elastic txwv Qhov kev ntxhov siab siab tshaj plaws uas cov khoom tuaj yeem rov qab tau zoo tom qab tshem tawm tom qab kev thauj khoom, tsis muaj qhov seem seem deformation raws li tus qauv. Thoob ntiaj teb, nws feem ntau yog qhia raws li ReL. Cov khoom raug txiav txim siab los tawm thaum qhov kev ntxhov siab tshaj ReL.
(3) Lub zog tawm los yog raws li qee qhov seem deformation. Piv txwv li, 0.2% residual deformation kev ntxhov siab feem ntau yog siv los ua lub zog tawm los, thiab lub cim yog Rp0.2.
4. Cov yam ntxwv cuam tshuam rau kev tawm dag zog ntawmflange
(1) Internal yam yog: ua ke, koom haum, qauv, atomic xwm.
(2) Sab nraud yam muaj xws li qhov kub thiab txias, tus nqi lim thiab lub xeev kev ntxhov siab.
φ yog ib chav dav dav, hais txog txoj kab uas hla ntawm cov kav dej thiab lub luj tshib, hlau thiab lwm yam ntaub ntawv, kuj tuaj yeem hais tias yog txoj kab uas hla, xws li φ 609.6mm yog hais txog txoj kab uas hla ntawm 609.6mm.
