Ngā Hangarau Hurihuri i roto i ngā Pūnaha Hiri Waka: He Whakamārama Whānui i te Hanganga me ngā Whakamahinga Ahumahi o ngā Hiri Tapa Hiki

Kupu Whakataki

I te mea kua whakatakotohia e Tesla Model Y tētahi paerewa ahumahi hou me te mahi hiri matapihi taumata IP68 me te whakatutukitanga o te BYD Seal EV i te taumata haruru hau i raro i te 60dB i te tere o te 120km/h, kei te whanake haere ngā hiri taha hiki waka mai i ngā wāhanga taketake ki ngā waeine hangarau matua i roto i ngā waka atamai. E ai ki ngā raraunga mai i te Society of Automotive Engineers of China i te tau 2024, kua eke te mākete pūnaha hiri waka o te ao ki te 5.2 piriona tāra US, me te pikinga o te ōwehenga o ngā wāhanga hiri atamai ki te 37%.

I. Te Wetewete Hangarau o ngā Hiri: Ngā Ahuhanga Ahu-Toru i roto i ngā Rauemi, ngā Tukanga, me te Whakaurunga Atamai

Te Whanaketanga o ngā Pūnaha Rauemi

• Ethylene – Propylene – Diene Monomer (EPDM): He rauemi tuku iho, ka taea te tu atu i ngā pāmahana mai i te – 50°C ki te 150°C, ā, he ātete UV mō te 2000 hāora (ngā raraunga mai i te taiwhanga o SAIC). Heoi, he ngoikoretanga tōna, he iti te roa o te hiri hihiri.
• Elastomer Thermoplastic (TPE): Ko te rauemi matua o te whakatipuranga hou. Ka whakamahia e te Tesla Model 3 he hanganga hiato paparanga-toru (anga pakari + paparanga pahuka + paninga ātete-mau), ka tutuki te roa o te huringa hiki o te 150,000 ngā wā, he pikinga 300% ki te whakataurite ki te EPDM.
• Ngā Rauemi Whakakotahi Whakaora-ā-Iho: Kua whakawhanakehia e BASF tētahi hangarau moroiti-kapi ka taea te whakatika aunoa i ngā kapiti tae atu ki te 0.5mm. Kua whakaritea kia tāutahia ki ngā tauira hiko parakore a Porsche i te tau 2026.

Mahere Whakarōpūtanga Hanganga

Ngā Tukanga Hanga Atamai
●Ka whakamahia e te Volkswagen ID.7 te tūnga taiaho mō te huihuinga, ka tutuki te tika o te ±0.1mm me te whakakore i te 92% o ngā haruru hiki.
●Nā te hoahoa pūhara TNGA a Toyota kua piki ake te pai o te tiaki mā te 70%, me te wā whakakapinga wāhanga kotahi iti iho i te 20 meneti.
II. Te Tātari i te Horopaki Taupānga Ahumahi Ngā Painga: Te Whakaurunga Hangarau mai i ngā Waka Pāhihi ki ngā Marae Motuhake
Hou – Te Marae Waka Pūngao
●Hiri Ārai Wai: Ka whakamahia e te pūnaha tuanui rā o XPeng X9 he hanganga arai e whā-paparanga, e kore ai e uru ki roto i te whare i raro i te ua o te 100mm/h (kua whakamanahia e CATARC).
●Mana Whakahaere Pūngao: Ka whakaitihia e Li L9 te whakamahinga hiko o ngā motuka matapihi mā te 12% mā roto i ngā hiri tauwehenga waku iti (μ ≤ 0.25).
Ngā Wāhanga Waka Motuhake
●Taraka Taumaha: Kei te Foton Auman EST ngā wāhanga hiri ātete-hinu, e pupuri ana i te modulus rapa neke atu i te 5MPa i roto i te taiao tino makariri o te –40°C.
●Ngā Waka mō ngā Huarahi-Kāore: Ka whakamahia e te Tank 500 Hi4 – T ngā hiri whakakaha-whakarewa, hei whakanui ake i te hohonutanga o te kaukaukau ki te 900mm.
Te Whakawhanuitanga o te Hanganga Atamai
●E whakauru ana te pūnaha iSeal 4.0 a Bosch i ngā pūoko moroiti e 16, e āhei ai te aroturuki i te wā-tūturu me te tiaki matapae i te tūnga hiri.
●Ka taea e te pūnaha whai a ZF i te poraka mekameka te whai i ngā tūemi raraunga matua e 18 pērā i ngā puranga rauemi mata me ngā tukanga whakaputa.
III. Ngā Aronga o te Whanaketanga Hangarau: Ngā Huringa Ahumahi i Kawea mai e te Whakaurunga Matatini
Ngā Pūnaha Taunekeneke Taiao
Kua whakawhanakehia e Continental tētahi rauemi hiri e aro ana ki te makuku me te tere pupuhi wai tae atu ki te 15%, e whakamaheretia ana kia whakamahia i roto i te raupapa Mercedes-Benz EQ i te tau 2027.
Ngā Pūnaha Hanga Tauwhiro
Kua whakaitihia e te rauemi TPU koiora a Covestro tōna tapuwae waro mā te 62%, ā, kua paahitia e ia te tiwhikete mekameka tuku mō te BMW iX3.
Hangarau Mahanga Mamati
Mā te tūāpapa whakatauira ANSYS ka taea te whakamātautau mariko o ngā pūnaha hiri, ka whakapotohia te huringa whanaketanga mā te 40% me te whakaiti i te para rauemi mā te 75%.
Whakamutunga
Mai i te hoahoa hanganga ngota o ngā rauemi ki te whakaurunga o ngā pūnaha whatunga atamai, kei te pakaru te hangarau hiri motuka i ngā rohe tuku iho. I te mea e whakaarohia ana e te kahui taraiwa motuhake a Waymo he paerewa pakari o te 2 miriona huringa, ka haere tonu tēnei whakataetae hangarau e pā ana ki te tika o te 0.01 – mirimita ki te akiaki i te umanga motuka ki te pono me te mohio teitei ake.
