Tsim ntawm I Beam

Oct 25, 2023 Tso lus

Ib qho I beam yog tsim los ntawm kev siv ob lub dav hlau ntev-tawm-tawm hu ua flange, txuas los ntawm cov khoom siv txuas txuas hu ua web. Tag nrho lub cev ntawm tus qauv no muaj ib qho I lossis H-shaped cross-section. Ib sab ntawm cov hlau, cov kab teeb ua los ntawm aluminium alloys thiab cov hlau tsis tshua muaj hlau kuj tseem siv tau rau ntau lub hom phiaj xws li txuas hniav, lub tsev thav duab, thiab lwm yam.

 

I beams yog tsim nyob rau hauv ntau qhov ntev, thicknesses, widths, thiab lwm yam specs rau ntau yam kev siv. Cov neeg siv khoom faib cov kab no raws li lawv cov khoom siv thiab qhov ntau thiab tsawg. Piv txwv li, ib tug 12-inch in-depth thiab 20 phaus / ko taw nyob rau hauv hnyav beam yog teev li 12 × 20. Cov neeg cog lus xaiv qhov ntev ntawm cov kab teeb rau lawv qhov project xav tau. Thaum txiav txim siab, cov hauv qab no yuav tsum tau xav txog:

Deflection.Lub thickness yuav tsum txaus txaus kom txo qhov deflection.

Kev vibration. Kev vibration me me li sai tau yuav tsum tau tsom thaum xaiv. Qhov nruj thiab qhov loj ntawm lub nqaj yog qhov tseem ceeb hauv qhov no.

Khoov. Lub cev lub cev yuav tsum muaj zog txaus los tiv thaiv kev tawm dag zog. Txwv tsis pub khoov tshwm sim.

Buckling.Torsional kev nyuaj siab ua rau kuv beam rau buckle uas tuaj yeem ua rau qhov tsis xav tau. Flanges yuav tsum tau xaiv raws li.

Kev ntxhov siab.Xaiv qhov I beam nrog txoj cai web thickness yog qhov tseem ceeb los tiv thaiv rippling los yog buckling nyob rau hauv nro.

 

Kuv beams yog tsim los khoov es buckle thaum nyob rau hauv siab load. Qhov ceev ntawm lub beam yog non-uniform. Cov cheeb tsam, qhov twg cov axial fibers nyob, muaj qhov ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom. Beams uas muaj qhov me me hla ntu yog qhov zoo tshaj plaws vim tias cov khoom siv tsawg yog xav tau yam tsis muaj kev cuam tshuam cov duab uas xav tau.
