Yuav ua li cas xaiv txoj hlua dynamic zoo?

Cov hlua nce toj muaj peev xwm muab faib ua cov hlua dynamic thiab cov hlua static. Cov hlua dynamic muaj qhov ductility zoo yog li thaum muaj qhov poob, cov hlua tuaj yeem ncab mus rau qee qhov kom qeeb qhov kev puas tsuaj los ntawm kev poob sai rau tus neeg nce toj.

Muaj peb txoj kev siv ntawm txoj hlua dynamic: ib txoj hlua, ib nrab txoj hlua, thiab ob txoj hlua. Cov hlua uas sib haum rau ntau yam kev siv sib txawv yog txawv. Ib txoj hlua yog qhov siv dav tshaj plaws vim tias kev siv yooj yim thiab yooj yim rau kev khiav lag luam; Ib nrab txoj hlua, tseem hu ua ob txoj hlua, siv ob txoj hlua kom raug khi rau hauv thawj qhov chaw tiv thaiv tib lub sijhawm thaum nce toj, thiab tom qab ntawd ob txoj hlua raug khi rau hauv ntau qhov chaw tiv thaiv kom qhov kev taw qhia ntawm txoj hlua tuaj yeem hloov kho tau zoo thiab qhov kev sib txhuam ntawm txoj hlua tuaj yeem txo qis, tab sis kuj nce kev nyab xeeb vim muaj ob txoj hlua los tiv thaiv tus neeg nce toj. Txawm li cas los xij, nws tsis tshua siv hauv kev nce toj tiag tiag, vim tias txoj kev ua haujlwm ntawm hom hlua no nyuaj, thiab ntau tus neeg nce toj siv txoj kev ntawm kev sling thiab dai sai, uas kuj tuaj yeem kho qhov kev taw qhia ntawm ib txoj hlua zoo dua;
Txoj hlua ob chav yog los muab ob txoj hlua nyias nyias ua ke rau hauv ib qho, kom tiv thaiv kev sib tsoo ntawm txoj hlua raug txiav thiab poob. Feem ntau, ob txoj hlua ntawm tib lub hom, qauv, thiab pawg yog siv rau kev nce hlua; Cov hlua nrog txoj kab uas hla loj dua muaj peev xwm dais tau zoo dua, tiv taus kev sib txhuam, thiab ruaj khov, tab sis kuj hnyav dua. Rau kev nce hlua ib leeg, cov hlua nrog txoj kab uas hla ntawm 10.5-11 hli yog qhov tsim nyog rau cov haujlwm uas xav tau kev tiv thaiv kev hnav siab, xws li nce phab ntsa pob zeb loj, tsim cov dej khov, thiab cawm, feem ntau ntawm 70-80 g / m. 9.5-10.5 hli yog qhov tuab nruab nrab nrog qhov siv tau zoo tshaj plaws, feem ntau 60-70 g / m. Txoj hlua 9-9.5 hli yog qhov tsim nyog rau kev nce hlua hnyav lossis nce ceev, feem ntau ntawm 50-60 g / m. Txoj kab uas hla ntawm txoj hlua siv rau kev nce hlua ib nrab yog 8-9 hli, feem ntau tsuas yog 40-50 g / m. Lub txoj kab uas hla ntawm txoj hlua siv rau kev nce hlua yog li 8 hli, feem ntau tsuas yog 30-45g / m2.

Kev cuam tshuam
Lub zog cuam tshuam yog qhov qhia txog kev ua tau zoo ntawm txoj hlua, uas yog qhov muaj txiaj ntsig zoo rau cov neeg nce toj. Tus nqi qis dua, qhov kev ua tau zoo ntawm txoj hlua zoo dua, uas tuaj yeem tiv thaiv cov neeg nce toj zoo dua. Feem ntau, lub zog cuam tshuam ntawm txoj hlua qis dua 10KN.

Txoj kev ntsuas tshwj xeeb ntawm lub zog cuam tshuam yog: txoj hlua siv thawj zaug poob thaum nws hnyav 80kg (kilograms) thiab qhov poob factor (Fall Factor) yog 2, thiab qhov siab tshaj plaws uas txoj hlua dais. Ntawm lawv, qhov poob coefficient = qhov nrug ntsug ntawm qhov poob / qhov ntev ntawm txoj hlua zoo.

Kev kho dej tsis nkag
Thaum cov hlua ntub dej lawm, qhov hnyav yuav nce ntxiv, tus naj npawb ntawm kev ntog yuav txo qis, thiab cov hlua ntub yuav khov ntawm qhov kub qis thiab ua ib lub khob noom qab zib. Yog li ntawd, rau kev nce toj siab, nws yog qhov tsim nyog heev uas yuav tsum siv cov hlua tiv dej rau kev nce dej khov.

Tus naj npawb siab tshaj plaws ntawm kev poob
Tus naj npawb ntawm kev poob ntau tshaj plaws yog qhov qhia txog lub zog ntawm txoj hlua. Rau ib txoj hlua, tus naj npawb ntawm kev poob ntau tshaj plaws yog hais txog tus coefficient ntawm kev poob ntawm 1.78, thiab qhov hnyav ntawm cov khoom poob yog 80 kg; Rau ib nrab txoj hlua, qhov hnyav ntawm cov khoom poob yog 55 kg, thiab lwm yam mob tseem tsis hloov pauv. Feem ntau, tus naj npawb ntawm kev poob ntau tshaj plaws ntawm txoj hlua yog 6-30 zaug.

Kev nthuav dav
Qhov ductility ntawm txoj hlua muab faib ua dynamic ductility thiab static ductility. Dynamic ductility sawv cev rau feem pua ​​ntawm kev nthuav dav ntawm txoj hlua thaum txoj hlua dais qhov hnyav ntawm 80 kg thiab qhov poob coefficient yog 2. Static extensibility sawv cev rau feem pua ​​ntawm kev nthuav dav ntawm txoj hlua thaum nws dais qhov hnyav ntawm 80 kg ntawm so.
