Iiprofayili ze-Aluminiyam zisetyenziswa kakhulu njengezixhobo zenkxaso, ezifana nezakhelo zezixhobo, imida, imiqadi, izibiyeli, njl njl. Ukubalwa kwe-deformation kubaluleke kakhulu xa ukhetha iiprofayili ze-aluminium. Iiprofayili ze-Aluminiyam ezinobunzima obuhlukeneyo bodonga kunye namacandelo ahlukeneyo ahlukeneyo aneenguqu ezahlukeneyo zoxinzelelo.
Indlela yokubala umthamo wokuthwala umthwalo weeprofayili ze-aluminium ye-industrial? Sidinga kuphela ukwazi ukubala njani ukuguqulwa kweeprofayili ze-aluminium ye-industrial. Ukwazi ukuguqulwa kweeprofayili ze-aluminium yezoshishino, sinokubala umthamo wokuthwala umthwalo weeprofayili.
Ngoko ke ubala njani i-deformation esekelwe kumandla kwiprofayili?
Makhe siqale sijonge iindlela eziphambili zokulungisa iiprofayili ze-aluminium. Kukho iintlobo ezintathu: ezilungisiweyo kwelinye icala, zixhaswe kuzo zombini iziphelo, kwaye zilungiswe kuzo zombini iziphelo. Iifomula zokubala zamandla kunye nokuguqulwa kwezi ndlela zintathu zokulungisa zahlukile.
Makhe siqale sijonge ifomula yokubala ukuguqulwa kweeprofayili ze-aluminium phantsi komthwalo omileyo:
Ezi zingentla ziyifomula zokubala ukuguqulwa komthwalo we-static xa isiphelo esinye sisisigxina, zombini iziphelo zixhaswa, kwaye zombini iziphelo zilungisiwe. Inokubonwa kwifomyula ukuba isixa-mali se-deformation sikhulu kakhulu xa esinye isiphelo sisisigxina, silandelwa yinkxaso kuzo zombini iziphelo, kwaye i-deformation encinci xa iziphelo zombini zilungiswa.
Makhe sijonge kwifomula yokubala i-deformation phantsi komthwalo:
Olona xinzelelo luvumelekileyo lokugoba lweeprofayile ze-aluminiyam:
Ukugqithisa olu xinzelelo kunokubangela ukuba iprofayili ye-aluminium iqhekeze okanye iphuke.
m: ingxinano yomgca weprofayile yealuminiyam (kg/cm3)
F: Layisha (N)
L: Ubude beprofayili yeAluminiyam
E: Imodyuli yeelastiki (68600N/mm2)
Mna: inertia edibeneyo (cm4)
Z: Inertia yamacandelo (cm3)
g: 9.81N/kgf
f: Imali yotshintsho (mm)
Yenza umzekelo
Oku ngasentla yifomula yokubala yokuguqulwa kwamandla kwiiprofayili ze-aluminium ye-industrial. Ukuthatha iphrofayili ye-aluminium ye-4545 njengomzekelo, sele sisazi ukuba ubude beprofayili ye-aluminium yi-L = 500mm, umthwalo ngu-F = 800N (1kgf = 9.81N), kwaye zombini iziphelo zixhaswa ngokusisigxina, ngoko ke i-aluminium iprofayili ye-deformation = iformula yokubala amandla yeeprofayili ze-aluminium yoshishino yile: indlela yokubala: isixa se-deformation δ = (800 × 5003) / 192 × 70000 × 15.12 × 104≈0.05mm. Le yimali yokuguqulwa kweprofayili ye-4545 ye-aluminium yoshishino.
Xa sisazi i-deformation yeeprofayili ze-aluminium ye-industrial, sibeka ubude kunye nokuguqulwa kweeprofayili kwifomula yokufumana umthamo wokuthwala. Ngokusekelwe kule ndlela, sinokunika umzekelo. Ukubalwa komthwalo wemitha ye-1 imitha ye-1 imitha usebenzisa i-2020 yeeprofayili ze-aluminium ye-industrial ibonisa ngokucacileyo ukuba umthamo wokuthwala umthwalo ngu-20KG. Ukuba isakhelo silungisiwe, umthamo wokuthwala umthwalo unokunyuswa ukuya kwi-40KG.
Aluminiyam iprofayile deformation ngokukhawuleza itheyibhile khangela
I-aluminium yeprofayili ye-deformation ekhawulezayo itafile yokutshekisha isetyenziselwa ukuchaza inani le-deformation eliphunyezwe ngamaprofayili e-aluminium yeenkcukacha ezahlukeneyo phantsi kweempembelelo zamandla angaphandle phantsi kweendlela ezahlukeneyo zokulungiswa. Le mali yokuguqulwa inokusetyenziswa njengereferensi yamanani kwiipropati ezibonakalayo zesakhelo seprofayili ye-aluminium; abaqulunqi bangasebenzisa lo mzobo ulandelayo ukubala ngokukhawuleza ukuguqulwa kweeprofayili ze-aluminium kwiinkcazo ezahlukeneyo kumazwe ahlukeneyo;
Ubungakanani beprofayili yeAluminiyam yokunyamezela
Uluhlu lokunyamezela iprofayili yeAluminiyam
Iprofayile yeAluminiyam enqamlezileyo ukunyamezelana komgca othe ngqo
Iprofayili yeAluminiyam yokunyamezela umgca othe ngqo
Ukunyamezela i-angle yeprofayili ye-aluminium
Ngaphezulu sidwelise uluhlu oluqhelekileyo lokunyamezelana kwe-aluminiyam ngokweenkcukacha kwaye sanikezela ngedatha eneenkcukacha, esinokuzisebenzisa njengesiseko sokugqiba ukuba ngaba iiprofayili ze-aluminium ziyimveliso efanelekileyo. Kwindlela yobhaqo, nceda ubhekisele kumzobo weskimu ongezantsi.
