I ka loaʻa ʻana o nā kaʻa uila (EVs) i kaulana i ka honua holoʻokoʻa, ke piʻi nei ka koi no nā mea māmā a paʻa i kā lākou hana. Aluminum extrusion alloys ua puka mai e like me ka holoholona hihiu-hoʻololi i loko o kaʻoihana kaʻa,ʻoiai lākou e hāʻawi ana i nā pono he nui e like me ka hoʻonui ʻana i ka ikaika o ke kūkulu ʻana, ka hoʻemi kaumaha, a me ka hoʻonui ʻana i ka ikehu. Ma kēia ʻatikala, e ʻimi mākou i kekahi o nā hoʻohana hou ʻana o nā alumini extrusion alloys i nā EV, ʻoi aku hoʻi i nā pā pākaukau, nā pale kiaʻi, a me nā pā pā hoʻomaha.

Pākuʻi Paʻa a me ka Guardrail

ʻO ka pilikia mua no kapā pākaukauʻo ia ka mea, pono e loaʻa ka hana piha maikaʻi loa a me ke kumukūʻai kūpono a kūpono hoʻi. Ma lalo o nā kūlana o kēia manawa, ʻo ka alumini ka mea i makemake nui ʻia, ʻoi aku ka maikaʻi ma mua o ke kila a me ka carbon fiber reinforced plastic matrix composites (CFRP).

Aneane a pau kumu kaʻa lako manufacturing hui e hoʻohana alumini extrusions e hana i nā pā pākaukau, e like me BMW, Audi Group, Volvo, etc. Ma ka manawa like, kekahi mau hui i hoihoi loa i loko o Tesla's all-aluminum skateboard pā pahu pahu i hanaia o extruded aluminika, a ua hahai like, e like me ka BMW i20 EVs pā kaʻa, Audi's e-tron uila kaʻa pā, Pallets no Daimler's EQ laula o nā kaʻa uila a oi. Ua hana ʻia nā pā mua o Audi me nā ʻāpana alumini i hoʻoheheʻe ʻia, akā ua hoʻololi ʻia me ka alumini extruded. ʻO kāna mau pā pākaukau no nā BEV a me nā PHEV i hana ʻia me ka alumini extruded.

He mea pono e hoʻomaopopo i kekahi mau ʻoihana i hana i nā pallets mai ke kila ke hoʻololi nei i ka alumini. No ka laʻana, ʻo Nissan Motor Company's Leaf EV kaʻa uila i hoʻohana i ke kila e hana i nā pā pākaukau, akā ua hoʻololi ʻia i ka alumini extruded ma 2018; Volkswagen i mau wahi palupalu no ke kila pila pila, akā, kona hou BEV uila kaʻa pila pila like pū me kēia i alakai i ka hoʻohana 'ana i ka alumini extruded; Ua hoʻoholo ʻo AkelMittal e hoʻohana i ke kila ikaika kiʻekiʻe no ke kino o ke kaʻa Tesla Model 3, akā ma hope ua ʻike ʻo ia ʻaʻole i kūlike ke kino o ke kila i ka pilina o ka pā pahu pahu alumini, no laila ua hoʻololi ʻia i kahi kino alumini alumini.

ʻO ka pahu hoʻoluʻu alumini hou

I ka makahiki 2018, ua hoʻokumu ʻo Constellium's Brunel Advanced Solidification Technology Center i kahi hoʻolālā tray hou i kapa ʻia ʻo "cold aluminum", nona ka ikaika hoʻoluʻu ikaika no nā pā pākaukau. Me kēia hoʻolālā, ʻaʻohe pono no ka friction stir welding pili hou. Ua hōʻike ʻia nā hoʻāʻo ʻana ua pili paʻa ka pā anuanu a ʻaʻole e kahe, a i ka manawa like, maʻalahi a wikiwiki ka pilina. I ka hoʻāʻo ʻana me ke ʻano hoʻoluʻu hui ʻana, ua loaʻa kahi hopena hoʻoluʻu ʻoluʻolu loa, a ʻo ±2 °C wale nō ka haʻalele ʻana o ka mahana. No laila, hoʻolōʻihi ʻia ke ola lawelawe o ka pā pākaukau, a hoʻomaikaʻi ʻia ka hana palekana. Hana ʻia kekahi mau ʻāpana o ka pā mai ka alumini extruded a kulou, me ka ʻole o ka wili ʻana a i ʻole ke kuʻi ʻana, a hāʻule ka nui o ka hoʻolālā hou e 15%.

Hoʻokaʻaʻike me mākou no ka ninau hou aku.
