Kodi Opanga Mbiri ya Aluminiyamu Amawerengera Bwanji Mbiri Yonyamula Katunduyo?

Mbiri za aluminiyamu zimagwiritsidwa ntchito ngati zipangizo zothandizira, monga mafelemu a zipangizo, malire, matabwa, mabatani, ndi zina zotero. Kuwerengera kwa mapindikidwe ndikofunikira kwambiri posankha mbiri ya aluminiyamu. Mbiri za aluminiyamu zokhala ndi makulidwe osiyanasiyana a khoma ndi magawo osiyanasiyana ophatikizika amakhala ndi zovuta zosiyanasiyana.

Momwe mungawerengere kuchuluka kwa katundu wamaprofayilo a aluminiyamu yamafakitale? Timangofunika kudziwa momwe tingawerengere mapindikidwe a mbiri ya aluminiyamu yamafakitale. Podziwa mapindikidwe a mbiri ya aluminiyamu yamafakitale, titha kuwerengeranso mphamvu yonyamula katundu wambiri.

Ndiye momwe mungawerengere ma deformation potengera mphamvu pa mbiri?

Tiyeni tiyang'ane kaye njira zazikulu zokonzera mbiri ya aluminiyamu. Pali mitundu itatu: yokhazikika kumapeto kumodzi, yothandizidwa pa malekezero onse awiri, ndi yokhazikika pamapeto onse awiri. Njira zowerengera mphamvu ndi kusinthika kwa njira zitatu zokonzera izi ndizosiyana.

Tiyeni tiyang'ane kaye njira yowerengera ma deformation a aluminiyamu pansi pa static load:

Zomwe zili pamwambazi ndizomwe zimawerengetsera static load deformation pamene mapeto amodzi akhazikika, malekezero onse amathandizidwa, ndipo mapeto onse amakhazikika. Zitha kuwoneka kuchokera ku ndondomeko kuti chiwerengero cha deformation ndi chachikulu kwambiri pamene mapeto amodzi akhazikika, kutsatiridwa ndi chithandizo pa malekezero onse awiri, ndipo kusinthika kochepa kwambiri ndi pamene mapeto onse akhazikika.

Tiyeni tiwone njira yowerengera deformation popanda katundu:

Kupsyinjika kwakukulu kovomerezeka kwa mbiri ya aluminiyamu:

Kupitilira kupsinjika uku kungayambitse mbiri ya aluminiyamu kusweka kapena kusweka.

m: kachulukidwe kakang'ono ka mbiri ya aluminiyamu (kg/cm3)

F: Katundu (N)

L: Kutalika kwa mbiri ya Aluminium

E: Elastic modulus (68600N/mm2)

I: Collective Inertia (cm4)

Z: Inertia yam'mbali (cm3)

g: 9.81N/kgf

f: kuchuluka kwa kusintha (mm)

Perekani chitsanzo

Zomwe zili pamwambazi ndi njira yowerengera mphamvu yosinthira mbiri ya aluminiyamu yamafakitale. Kutengera mbiri ya aluminiyamu ya 4545 monga chitsanzo, tikudziwa kale kuti kutalika kwa mbiri ya aluminiyamu ndi L = 500mm, katunduyo ndi F = 800N (1kgf = 9.81N), ndipo malekezero onse awiri amathandizidwa mokhazikika, ndiye kuchuluka kwa mawonekedwe a aluminiyamu. = mphamvu mawerengedwe chilinganizo cha mbiri zotayidwa mafakitale ndi: mawerengedwe njira ndi: mapindikidwe kuchuluka δ = (800×5003) / 192×70000×15.12×104≈0.05mm. Uku ndiye kuchuluka kwa mawonekedwe a 4545 mafakitale aluminiyamu.

Tikadziwa mapindikidwe a mbiri ya aluminiyamu yamafakitale, timayika kutalika ndi kusinthika kwa ma profayilo kuti tipeze mphamvu. Kutengera njira iyi, titha kupereka chitsanzo. Kuwerengera katundu wa 1 mita 1 mita 1 mita pogwiritsa ntchito mbiri ya aluminiyamu yamafakitale 2020 kukuwonetsa kuti mphamvu yonyamula katundu ndi 20KG. Ngati chimango chapangidwa, mphamvu yonyamula katundu imatha kuonjezedwa mpaka 40KG.

Aluminium mbiri deformation mwachangu cheke tebulo

The aluminiyamu mbiri deformation mwamsanga cheke tebulo makamaka ntchito kufotokoza deformation kuchuluka akwaniritsa ndi aluminiyumu mbiri za specifications motsogozedwa ndi mphamvu zakunja pansi njira zosiyanasiyana fixation. Kuchuluka kwa deformation kumeneku kungagwiritsidwe ntchito ngati nambala yowerengera zinthu zakuthupi za chimango cha aluminiyamu; okonza angagwiritse ntchito chiwerengero chotsatirachi kuti awerenge mofulumira mapindikidwe a mbiri ya aluminiyamu yazinthu zosiyanasiyana m'mayiko osiyanasiyana;

Aluminium mbiri kukula kulolerana osiyanasiyana

Aluminium mbiri torsion tolerance range

Mbiri ya aluminiyamu yopingasa mizere yowongoka

Aluminiyamu mbiri longitudinal molunjika mzere kulolerana

Aluminiyamu mbiri angle kulolerana

Pamwambapa talemba mndandanda wamtundu wa aluminiyamu wololera mwatsatanetsatane ndikupereka zambiri, zomwe titha kugwiritsa ntchito ngati maziko kuti tidziwe ngati mbiri ya aluminiyamu ndi zinthu zoyenerera. Kuti mupeze njira yodziwira, chonde onani chithunzi chomwe chili pansipa.
