Aluminium profiles feem ntau yog siv los ua cov ntaub ntawv txhawb nqa, xws li cov khoom siv thav duab, ciam teb, kab teeb, brackets, thiab lwm yam. Kev suav ntawm deformation yog qhov tseem ceeb heev thaum xaiv aluminium profiles. Aluminium profiles nrog txawv phab ntsa thicknesses thiab sib txawv cross-section muaj txawv kev ntxhov siab deformations.
Yuav ua li cas los laij lub peev xwm ntawm kev lag luam aluminium profiles? Peb tsuas yog yuav tsum paub yuav ua li cas los xam cov deformation ntawm industrial aluminium profiles. Paub txog qhov deformation ntawm kev lag luam aluminium profiles, peb kuj tuaj yeem xam cov peev txheej ntawm cov khoom siv.
Yog li yuav ua li cas xam cov deformation raws li lub zog ntawm qhov profile?
Cia peb xub saib cov hauv paus ntsiab lus los txhim kho aluminium profiles. Muaj peb hom: tsau ntawm ib kawg, txhawb nqa ntawm ob qho kawg, thiab tsau ntawm ob qho kawg. Cov qauv kev suav rau kev quab yuam thiab deformation ntawm peb txoj kev kho no txawv.
Cia peb xub saib cov qauv rau kev xam cov deformation ntawm txhuas profiles nyob rau hauv static load:
Cov saum toj no yog cov qauv rau kev xam cov static load deformation thaum ib kawg yog tsau, ob qho tag nrho cov kev txhawb nqa, thiab ob qho tib si xaus. Nws tuaj yeem pom los ntawm cov qauv uas qhov deformation tus nqi yog qhov loj tshaj plaws thaum ib kawg yog kho, ua raws li kev txhawb nqa ntawm ob qho kawg, thiab qhov deformation tsawg tshaj plaws yog thaum ob qho tag nrho raug kho.
Cia peb saib cov qauv rau kev xam deformation nyob rau hauv tsis muaj load:
Qhov siab tshaj plaws tso cai khoov kev nyuaj siab ntawm aluminium profiles:
Tshaj qhov kev ntxhov siab no yuav ua rau cov txhuas profile tawg lossis tawg.
m: linear ceev ntawm txhuas profile (kg / cm3)
F: Load (N)
L: Aluminium profile ntev
E: Elastic modulus (68600N / mm2)
Kuv: collective inertia (cm4)
Z: Hla-sectional inertia (cm3)
g: 9.81 kwg
f: Deformation tus nqi (mm)
Muab piv txwv
Cov saum toj no yog cov mis laij lej rau lub zog deformation ntawm kev lag luam aluminium profiles. Noj 4545 txhuas profile ua piv txwv, peb twb paub lawm tias qhov ntev ntawm aluminium profile yog L = 500mm, lub load yog F = 800N (1kgf = 9.81N), thiab ob qho tag nrho yog ruaj khov, ces cov txhuas profile deformation tus nqi. = lub zog xam mis ntawm kev lag luam aluminium profiles yog: txoj kev suav yog: deformation tus nqi δ = (800 × 5003) / 192 × 70000 × 15.12 × 104≈ 0.05mm. Qhov no yog tus nqi deformation ntawm 4545 muaj txhuas profile.
Thaum peb paub qhov deformation ntawm industrial aluminium profiles, peb muab qhov ntev thiab deformation ntawm cov profiles rau hauv cov mis kom tau txais cov kabmob muaj peev xwm. Raws li txoj kev no, peb tuaj yeem muab piv txwv. Kev suav cov kabmob ntawm 1 meter 1 meter 1 meter siv 2020 kev lag luam aluminium profiles roughly qhia tau hais tias lub peev xwm thauj khoom yog 20KG. Yog hais tias tus ncej yog paved, lub peev xwm load-bearing yuav nce mus rau 40KG.
Aluminium profile deformation ceev xyuas lub rooj
Aluminium profile deformation ceev check lub rooj yog tsuas yog siv los piav txog tus nqi deformation tiav los ntawm txhuas profiles ntawm txawv specifications nyob rau hauv tus ntawm sab nraud rog nyob rau hauv txawv fixation txoj kev. Qhov nyiaj deformation no tuaj yeem siv los ua tus lej siv rau lub cev lub cev ntawm aluminium profile ncej; cov neeg tsim qauv siv tau cov duab hauv qab no kom ceev nrooj xam qhov deformation ntawm aluminium profiles ntawm txawv specifications nyob rau hauv ntau lub xeev;
Aluminium profile loj kam rau ua ntau yam
Aluminium profile torsion kam rau ua ntau yam
Aluminium profile transverse ncaj kab kam rau ua
Aluminium profile longitudinal ncaj kab kam rau ua
Aluminium profile kaum tolerance
Saum toj no peb tau teev cov txheej txheem qhov ntev ntawm qhov ntev ntawm cov txhuas profile hauv kev nthuav dav thiab muab cov ntaub ntawv ntxaws ntxaws, uas peb tuaj yeem siv los txiav txim siab seb aluminium profiles yog cov khoom tsim nyog. Rau txoj kev kuaj pom, thov mus saib daim duab schematic hauv qab no.
