Amaphrofayili e-aluminium asetshenziswa kakhulu njengezinto zokusekela, njengamafreyimu wemishini, imingcele, imishayo, abakaki, njll. Ukubalwa kokuguqulwa kubaluleke kakhulu lapho ukhetha amaphrofayili e-aluminium. Amaphrofayili e-aluminium anobukhulu obuhlukene bodonga kanye nezigaba ezihlukene ezihlukene anokukhubazeka okuhlukile kokucindezeleka.
Ungabala kanjani umthamo wokuthwala umthwalo wamaphrofayili e-aluminium yezimboni? Sidinga kuphela ukwazi ukuthi singabala kanjani ukuguqulwa kwamaphrofayili e-aluminium yezimboni. Ukwazi ukuguqulwa kwamaphrofayili e-aluminium yezimboni, singakwazi futhi ukubala umthamo wokuthwala umthwalo wamaphrofayili.
Ngakho kanjani ukubala deformation ngokusekelwe amandla kuphrofayela?
Ake siqale sibheke izindlela eziyinhloko zokulungisa amaphrofayili e-aluminium. Kunezinhlobo ezintathu: ezigxilile ekugcineni, ezisekelwe kuzo zombili iziphetho, futhi zilungiswe kuzo zombili iziphetho. Amafomula wokubala amandla kanye nokuguqulwa kwalezi zindlela ezintathu zokulungisa ahlukile.
Ake siqale sibheke ifomula yokubala ukuguqulwa kwamaphrofayili e-aluminium ngaphansi komthwalo omile:
Okungenhla amafomula okubala ukuwohloka komthwalo omile lapho isiphetho esisodwa silungisiwe, zombili iziphetho ziyasekelwa, futhi zombili iziphetho zilungisiwe. Kungabonakala kufomula ukuthi inani le-deformation likhulu kakhulu lapho isiphetho esisodwa silungisiwe, kulandelwa ukusekelwa kuzo zombili iziphetho, futhi ukuwohloka okuncane kakhulu yilapho zombili iziphetho zilungisiwe.
Ake sibheke ifomula yokubala i-deformation ngaphansi komthwalo:
Ingcindezi enkulu yokugoba evunyelwe yamaphrofayili e-aluminium:
Ukweqa lokhu kucindezeleka kungase kubangele ukuthi iphrofayela ye-aluminium iqhekeke noma iphuke.
m: ukuminyana komugqa wephrofayili ye-aluminium (kg/cm3)
F: Layisha (N)
L: Ubude bephrofayili ye-Aluminium
E: Imoduli ye-elastic (68600N/mm2)
I: inertia ehlangene (cm4)
Z: Inertia ye-cross-sectional (cm3)
g: 9.81N/kgf
f: Inani lokuguqulwa (mm)
Nikeza isibonelo
Okungenhla ifomula yokubala ye-force deformation yamaphrofayili e-aluminium yezimboni. Ukuthatha iphrofayili ye-aluminium engu-4545 njengesibonelo, sesivele sazi ukuthi ubude bephrofayela ye-aluminium yi-L = 500mm, umthwalo ngu-F = 800N (1kgf = 9.81N), futhi zombili iziphetho zisekelwa ngokuqinile, khona-ke inani lephrofayili ye-aluminium deformation = ifomula yokubala yamandla yamaphrofayili e-aluminium yezimboni ithi: indlela yokubala ithi: inani lokuguquguquka δ = (800×5003) / 192×70000×15.12×104≈0.05mm. Leli inani le-deformation yephrofayili ye-aluminium yezimboni engu-4545.
Uma sazi ukuguqulwa kwamaphrofayili e-aluminium yezimboni, sibeka ubude nokuguqulwa kwamaphrofayili kufomula ukuze sithole umthamo wokuthwala. Ngokusekelwe kule ndlela, singanikeza isibonelo. Isibalo esithwala umthwalo esiyimitha elingu-1 imitha elingu-1 imitha sisebenzisa amaphrofayili e-aluminium yezimboni zika-2020 cishe sibonisa ukuthi umthamo wokuthwala umthwalo ungama-20KG. Uma ifreyimu igandayiwe, umthamo wokuthwala umthwalo unganyuswa ube ngu-40KG.
Ithebula lokuhlola elisheshayo le-aluminium deformation deformation
Ithebula lokuhlola iphrofayili ye-aluminium esheshayo lisetshenziselwa ukuchaza inani le-deformation elizuzwe amaphrofayili e-aluminium emininingwane ehlukene ngaphansi kwethonya lamandla angaphandle ngaphansi kwezindlela ezihlukene zokulungisa. Leli nani le-deformation lingasetshenziswa njengereferensi yezinombolo yezakhiwo ezibonakalayo zohlaka lwephrofayela ye-aluminium; abaklami bangasebenzisa isibalo esilandelayo ukubala ngokushesha ukuguqulwa kwamaphrofayili we-aluminium wezinto ezicacisiwe ezahlukene ezifundeni ezahlukene;
Ibanga lokubekezelela usayizi wephrofayela ye-aluminium
Ibanga lokubekezelela iphrofayili ye-aluminium
Iphrofayili ye-aluminium eguquguqukayo yokubekezelelana komugqa oqondile
Ukubekezelela komugqa oqondile wephrofayela ye-aluminium ubude
Ukubekezelela i-engeli yephrofayela ye-aluminium
Ngenhla sibhale ububanzi obujwayelekile bokubekezelelana kwe-aluminium ngokuningiliziwe futhi sanikeza idatha enemininingwane, esingayisebenzisa njengesisekelo sokunquma ukuthi amaphrofayili e-aluminium ayimikhiqizo efanelekile yini. Ukuze uthole indlela yokuthola, sicela ubhekisele kumdwebo wohlelo ongezansi.
