Kev tsim cov kem hlau thiab kev txhawb nqa
1. Cov qauv ntawm tus qauv ncej
Daim ntawv seem kem: lub thawv zoo li cas, welded I-puab, H-puab hlau, yeeb nkab puag ncig, thiab lwm yam
Kev kwv yees seem: Raws li 1.2N axial compression members, 3 ~ 4 txheej rau kev hloov pauv cross-section, qhov tuab yuav tsum tsis pub tshaj 100 hli
Qhov dav ntawm phaj rau qhov sib piv ntawm qhov tuab, saib cov lus hauv qab no
Qhov sib piv ntawm qhov nyias nyias: Cov ncej ntau txheej (£ 12 txheej) yuav tsum tsis txhob loj dua 120 thaum 6 txog 8 degrees ntawm kev tiv thaiv, thiab yuav tsum tsis txhob loj dua 100 thaum 9 degrees ntawm kev tiv thaiv. Thaum lub zog tiv thaiv yog 6, 7, 8 thiab 9 degrees, qhov siab ntawm cov ncej siab (> 12 plag tsev) yog 120, 80 thiab 60, raws li.
Cov "Cov Cai Kev Siv Tshuab rau Cov Qauv Hlau hauv Cov Tsev Siab Siab" (JGJ99-98) hais tias: thaum xam qhov ruaj khov nyob rau hauv kev sib xyaw ua ke ntawm lub ntiajteb txawj nqus thiab cua lossis av qeeg, yog tias tus nqi txheem ntawm kev hloov chaw ntawm cov plag tsev tsis tshaj 1/250 ntawm qhov siab ntawm cov ncej, qhov ntev ntawm cov ncej nrog kev txhawb nqa (lossis phab ntsa shear) tuaj yeem yog m = 1.0; Thaum tus nqi txheem ntawm kev hloov chaw ntawm cov plag tsev tsis tshaj 1/1000 ntawm qhov siab, qhov ntev ntawm cov ncej ntshiab kuj tuaj yeem suav los ntawm Wu cov qauv hloov chaw sab.
GB50017 rau cov thav duab txhawb nqa tau muab faib ua cov thav duab txhawb nqa muaj zog thiab cov thav duab txhawb nqa tsis muaj zog.
2, kem thiab beam kev sib txuas
★ Hom ntawv feem ntau: kev sib txuas ruaj khov
★ Vuam tag nrho
★ Tag nrho bolted
★ Kev sib xyaw ua ke ntawm kev vuam bolt
★ Zoo dua daim ntawv vuam tag nrho: pob txha sib koom ua ke (Aub pob txha), qhov kawg ntawm lub nqaj nrog axils, ntu ntawm lub nqaj cantilever
★ Daim ntawv txuas yooj ywm: txuas lub kaum sab xis hlau, phaj kawg, kev txhawb nqa
★ Kev sib txuas semi-rigid: phaj kawg - hom kev sib txuas bolt siab, sab saud thiab qis dua lub kaum sab xis hlau thiab hom kev sib txuas bolt siab
Zhuo Meng Shanghai Auto Co., Ltd. tau cog lus tias yuav muag MG&MAUXS cov khoom siv tsheb.
