O faʻamatalaga alumini e masani ona faʻaaogaina e avea ma mea lagolago, e pei o faʻavaa meafaigaluega, tuaoi, faʻalava, puipui, ma isi. O le faʻatusatusaina o le faʻaleagaina e taua tele pe a filifilia faʻamatalaga alumini. Fa'amatalaga alumini fa'atasi ai ma mafiafia puipui eseese ma va'aiga fa'asaga eseese e eseese fa'alavelave fa'alavelave.
E faʻapefea ona faʻatusatusa le gafatia o le amoina o faʻamatalaga alumini alamanuia? E tatau ona tatou iloa pe faʻapefea ona fuafua le faʻaleagaina o faʻamatalaga alumini alamanuia. O le iloaina o le faʻaleagaina o faʻamatalaga alumini alamanuia, e mafai foi ona tatou faʻatusatusaina le gafatia o faʻamatalaga.
E faʻafefea la ona faʻatatau le deformation e faʻavae i luga o le malosi i luga o le talaaga?
Sei o tatou tilotilo muamua i auala autu e faʻaleleia ai faʻamatalaga alumini. E tolu ituaiga: faʻamau i le tasi pito, lagolago i pito e lua, ma faʻamau i pito e lua. O fua fa'atatau mo le malosi ma le deformation o nei auala fa'apipi'i e tolu e 'ese'ese.
Seʻi o tatou vaʻavaʻai muamua i le fua faʻatatau mo le faʻatusatusaina o le faʻaleagaina o faʻamatalaga alumini i lalo o le avega mamafa:
O loʻo i luga o fua faʻatatau mo le faʻatusatusaina o le faʻaleagaina o uta pe a faʻapipiʻi le tasi pito, o pito e lua e lagolagoina, ma faʻamau uma pito. E mafai ona vaʻaia mai le fua faʻatatau o le aofaʻi o le deformation e sili ona tele pe a faʻapipiʻi le tasi pito, sosoo ai ma le lagolago i pito uma e lua, ma o le faʻaletonu laʻititi pe a faʻamautu pito uma e lua.
Sei o tatou vaʻai i le fua faʻatatau mo le faʻatusatusaina o le deformation i lalo o le leai o se uta:
Le maualuga o le mamafa fa'atagaina o fa'amauga alumini:
O le fa'ateleina o lenei fa'amamafa e mafai ona ta'e pe malepe ai le fa'ailoga alumini.

O loʻo i luga o le fua faʻatatau mo le faʻaleagaina malosi o faʻamatalaga alumini alamanuia. O le faʻaaogaina o le 4545 alumini faʻataʻitaʻiga e fai ma faʻataʻitaʻiga, ua uma ona tatou iloa o le umi o le faʻailoga alumini o le L = 500mm, o le uta o le F = 800N (1kgf = 9.81N), ma o pito uma e lua o loʻo lagolagoina mau, ona faʻamauina lea o le aofaʻi o le faʻasologa o le alumini. = le fua fa'atatau o le fa'atatauga alumini alamanuia: o le metotia fa'atatau o le: deformation aofa'i δ = (800×5003) / 192×70000×15.12×104≈0.05mm. O le aofaʻi faʻaleagaina lea o le 4545 alamanuia alumini faʻamatalaga.
A tatou iloa le deformation o alamanuia alumini talaaga otooto, tatou tuu le umi ma deformation o talaaga otooto i le fua e maua ai le gafatia tauave. Faʻavae i luga o lenei metotia, e mafai ona tatou tuʻuina atu se faʻataʻitaʻiga. Ole fua fa'atatau ole 1 mita 1 mita 1 mita ile fa'aogaina ole 2020 alamanuia alumini fa'amatalaga fa'ata'ita'i fa'aalia o le avega-tauave e 20KG. Afai o le faʻavaa e faʻapipiʻiina, e mafai ona faʻateleina le gafatia o le uta i le 40KG.
Alumini profile deformation laulau siaki vave
O le alumini profile deformation vave siaki laulau e masani lava ona faʻaaogaina e faʻamatala ai le aofaʻi o le deformation na maua e faʻamatalaga alumini o faʻamatalaga eseese i lalo o le faatosinaga a le malosi i fafo i lalo o auala eseese. O lenei aofaiga deformation e mafai ona faʻaaogaina e fai ma faʻamatalaga numera mo meatotino faʻaletino o le faʻailoga faʻapipiʻi alumini; e mafai e tagata mamanu ona faʻaogaina le ata o loʻo i lalo e faʻatatau vave ai le deformation o faʻamatalaga alumini o faʻamatalaga eseese i setete eseese;
Aluminum profile lapopoa faapalepale laina
Aluminum profile torsion tolerance range
Fa'ailoga alumini fa'apalepale laina sa'o fa'asaga
Fa'ailoga alumini fa'apalepale laina sa'o umi
Fa'apalepale tulimanu fa'ailoga alumini
I luga aʻe ua matou lisiina le tulaga masani o le faʻapalepale o faʻamatalaga alumini faʻamatalaga auiliili ma tuʻuina atu faʻamatalaga auʻiliʻili, lea e mafai ona matou faʻaogaina e fai ma faʻavae e fuafua ai pe o faʻamatalaga alumini o ni oloa agavaa. Mo le auala e su'e ai, fa'amolemole fa'afeso'ota'i le fa'asologa o ata o lo'o i lalo.
