Ngabe abakhiqizi bephrofayili ye-Aluminium bebala kanjani umthamo wamaphrofayili 'wokuthwala umthwalo?

Amaphrofayli we-Aluminium asetshenziswa kakhulu njengezinto zokwesekwa, njengezinsizakusebenza zemishini, imingcele, imishayo, amabakaki, njll. Ukubalwa kokungcola kubaluleke kakhulu lapho ukhetha amaphrofayili we-aluminium. Amaphrofayli we-Aluminium anobukhulu obuhlukahlukene odongeni kanye nezingxenye ezahlukahlukene zesiphambano zinokukhubazeka okuhlukile kwengcindezi.

Ungakubala kanjani umthamo othwala umthwalo wamaphrofayili we-aluminium wezimboni? Sidinga nje ukwazi ukuthi singabalwa kanjani ukubalwa kwamaphrofayili we-aluminium wezimboni. Ukwazi ukuguqulwa kwamaphrofayili we-aluminium we-alunum wezimboni, futhi singakwazi ukubala umthamo othwala umthwalo wamaphrofayili.

Ngakho-ke ukuthi ubala kanjani i-defformation ngokususelwa kumandla kuphrofayela?

Ake siqale ukubheka izindlela eziphambili zokulungisa amaphrofayili we-aluminium. Kunezinhlobo ezintathu: ezilungiselelwe ekugcineni okukodwa, ezisekelwa emikhawulweni yomibili, futhi zilungiswe emikhawulweni yomibili. Amafomula wokubala amandla kanye ne-deformation yalezi zindlela ezintathu zokulungisa ahlukile.

Ake siqale sibheke ifomula yokubala deformation of Aluminium Amaphrofayili ngaphansi kwemithwalo ye-tuli:

Lokhu okungenhla kukhona amafomula wokubala i-static umthwalo defformation lapho kulungiswa umkhawulo owodwa, zombili iziphetho ziyasekelwa, futhi zombili iziphetho zilungisiwe. Kungabonakala kusuka kwifomula yokuthi inani le-defformation likhulu kakhulu lapho ukuphela okukodwa kulungiswa, kulandelwe ukusekelwa kuzo zombili iziphetho, futhi i-deformation encane kunazo zonke lapho zombili iziphetho zilungisiwe.

Ake sibheke ifomula yokubala i-deformation ngaphansi komthwalo:

Ubukhulu bokuqashelwa kwengcindezi ye-aluminium profiles:

Ukudlula le ngcindezi kungadala ukuthi iphrofayili ye-aluminium ibe ukuqhekeka noma ihlukane.

M: Ubuningi obuqondile bephrofayili ye-aluminium (kg / cm3)

F: Layisha (n)

L: Ubude bephrofayili ye-Aluminium

E: I-Elastic Modulus (68600N / MM2)

I: I-Inertia ehlanganisiwe (cm4)

Nikeza isibonelo

Lokhu okungenhla kuyindlela yokubala ye-Force Deformation yamaphrofayili we-aluminium wezimboni. Ukuthatha iphrofayili ye-aluminium engu-4545 njengesibonelo, sesivele sazi ukuthi ubude bephrofayili ye-aluminium ngu-L = 500mm, umthwalo u-F = 800n (1kgf = 900) = Ifomula yokubala yamandla yamaphrofayili we-aluminium we-aluminium yi: Indlela yokubala yilena: Inani lokukhubazeka Δ = (800 × 5003) / 192 × 70000 × 15.12 × 104.05mm. Le yinani lokuchazwa kwephrofayili ye-Aluminium ye-4545 yezimboni.

Lapho sazi ukuguqulwa kwamaphrofayili we-aluminium zezimboni, sibeka ubude kanye ne-deformation of the profiles kwifomula ukuze uthole umthamo wokuthwala. Ngokusekelwe kule ndlela, singanikeza isibonelo. Ukubalwa okubalwa kwemitha kwemitha engu-1 metret 1 imitha 1 imitha usebenzisa amaphrofayili we-aluminium angama-2020 wezimboni akhombisa ngokusobala ukuthi umthamo othwala umthwalo ngu-20kg. Uma uhlaka luvinjelwe, umthamo othwala umthwalo ungakhushulwa uye ku-40kg.

I-Aluminium Profile Deformation Itafula Lokuhlola Okusheshayo

Ithebula le-Aluminium Deformation Quick Check Ithebula lisetshenziselwa ikakhulukazi ukuchaza inani le-defformation elitholwe amaphrofayili we-aluminium ezincazelo ezahlukahlukene ngaphansi kwethonya lamabutho angaphandle. Le mali defformation ingasetshenziswa njengereferensi yezinombolo yezindawo ezibonakalayo zohlaka lwephrofayili ye-aluminium; Abaqambi bangasebenzisa lesi sibalo esilandelayo ukuze balale ngokushesha ukuguquguquka kwamaphrofayili we-aluminium ezincazelo ezahlukahlukene ezifundeni ezahlukene;

Ibanga le-Aluminium Place Usayizi wokubekezelelana

I-Aluminium Profilion Torsion Ukubekezelela Ububanzi

I-Aluminium Profile Transverse Iqonde ukubekezelelana

I-Aluminium Profile Profile

I-Aluminium Profile Angle Ukubekezelelana

Ngaphezulu sibhale uhla lokubekezelelana olujwayelekile lwamaphrofayili we-aluminium ngokuningiliziwe futhi lunikeze imininingwane eningiliziwe, esingayisebenzisa njengesisekelo sokunquma ukuthi amaphrofayili we-aluminium ayimikhiqizo efanelekile. Ngendlela yokutholwa, sicela ubheke umdwebo we-schematic ngezansi.
