Ni ukubera iki imbaraga nyinshi-zipima Aluminiyumu isimbuza Titanium muri Exoskeletons ya Humanoid?

Mugihe umusaruro mwinshi wa robo ebyiri zabantu (nka Tesla Optimus, Boston Dynamics Atlas, hamwe na robo yungirije yinganda) byihuta muburyo bwo kohereza ibicuruzwa, guhitamo ibikoresho byubatswe byavuye mubikorwa byiza bigamije kuringaniza imbaraga, gukora imizigo, gusohora amashyanyarazi, hamwe nigiciro kinini cyo gukora.

Mugihe titanium alloys (Ti-6Al-4V) mumateka yiganjemo ikirere cyinshi cyane nikirere hamwe na exoskeletons ya gisirikare kubera imbaraga zabo zikomeye, imbaraga nyinshi-ziremereye zometse kuri aluminiyumu (7000 na 2000 ikurikirana hamwe na ceramic / anodised coatings) zirimo gusimbuza vuba titanium mubucuruzi bwa robot exoskeletons.

Inzitizi zubucuruzi za Titanium

Amavuta ya Titanium atanga imbaraga zidasanzwe zidasanzwe (> 900MPa), ariko agaragaza inzitizi zikomeye zo gukora robot nini cyane ya robo:

Imashini ikabije & Igikoresho cyo Kwambara Igiciro: Ubushyuhe buke bwa Titanium butera ubushyuhe bwinshi mugihe cyo gusya, bikaviramo gukata ibikoresho byihuse no kugabanuka kwibiryo.

Akaga gaterwa nubushyuhe bwa moteri: moteri yumuriro mwinshi imbere mumavi ya humanoid, ikibuno, nigitugu bitanga ubushyuhe bukomeza (80 ° C - 120 ° C). Ubushyuhe buke bwa Titanium butera imitego yubushyuhe, bishobora guteza moteri ya moteri.

Kugereranya: Titanium Alloy (Ti-6Al-4V) na Aluminium ifite imbaraga nyinshi (7075-T6 + MAO Coating)

Kugereranya ibikoresho bya Exoskeleton

Matrix iri hepfo igereranya Titanium Ti-6Al-4V na Aluminium ifite imbaraga nyinshi (7075-T6 + MAO Ceramic Coating):

Ibibazo

Q1: Ese aluminiyumu ifite imbaraga nyinshi ishobora guhuza titanium mubushobozi bwo gutwara imitwaro kumaguru ya muntu?

Igisubizo: Mugihe titanium ifite imbaraga zidasanzwe zingana, aluminium 7075-T6 igera kumbaraga zisa (imbaraga-nuburemere). Mugutezimbere uburebure bwurukuta hamwe na geometrie ya rubavu, ingingo ya aluminiyumu yakozwe itwara imitwaro ihwanye nuburemere buke hamwe nigiciro.

Q2: Nigute Oxidation ya Micro-Arc (MAO) irinda kwambara hejuru ya aluminiyumu mu ngingo za robo?

Igisubizo: MAO ikoresha plasma isohoka mumazi ya electrolyte yo mumazi kugirango ikure igicucu cyinshi, cristal ceramic ceramic ( Al ₂ O ₃) iturutse hanze ya aluminium. Uru rupapuro ntirushobora gukuramo kandi ruzamura ubukana bwa 500 - 1000 HV , rukarinda intera ihuriweho no kwambara.

Q3: Ni ukubera iki ubushyuhe bwumuriro ari ingenzi cyane kuri robot exoskeletons ya kimuntu?

Igisubizo: Humanoid ihuza inzu moteri yumuriro mwinshi wa moteri ikora ubudahwema mumashanyarazi. Ubushyuhe bukabije bwa Aluminium ( 130 - 180 W / m · K ) ikwirakwiza ubushyuhe bwa moteri mu kirere kidukikije, bikarinda gutwarwa n’ubushyuhe kandi bikongerera ubuzima moteri.

Q4: Amafaranga angahe yo kuzigama atanga aluminiyumu atanga hejuru ya titanium?

Igisubizo: Gusimbuza titanium na aluminiyumu ifite imbaraga nyinshi bigabanya amafaranga y’ibikoresho fatizo ku gipimo cya 60% - 70%  naho amafaranga yo gutunganya agera kuri 80% , bigatuma ibiciro rusange bya exoskeleton bigabanuka hejuru ya 70%.

Q5: Ese aluminium 7075-T6 irashobora guhangayikishwa no kwangirika kwangirika mubidukikije bya robo?

Igisubizo: Bare 7075-T6 irashobora kwibasirwa no kwangirika kwikirere. Gukoresha igicucu cyinshi cya anodize cyangwa MAO ceramic ceramic gifunga burundu hejuru yubutaka, bigatuma imiti irwanya imiti yangirika kandi ikangirika mugihe cyo gukora robot yo hanze.

Umwanzuro

Imbaraga nyinshi-ziremereye aluminiyumu itanga uburinganire bwiza bwimbaraga zihariye, kuramba hejuru, gucunga amashyuza, hamwe nigiciro cyogukoresha robot robot exoskeletons.

Kugirango uhindure ibikoresho byatoranijwe kubishushanyo mbonera bya robo:

Kugaragaza 7075-T6 cyangwa 2024-T3 Imyunyu ngugu ikomeye: Koresha 7075-T6 kumaguru nyamukuru, ikibuno, hamwe numugongo byubaka bisaba imbaraga nyinshi (> 500 MPa).

Manda ya Micro-Arc Oxidation (MAO) Ipitingi (20μm - 30μm): Saba ubuvuzi bwa MAO ceramic hejuru yintebe zambaye imyenda myinshi hamwe ningingo zubatswe kugirango ugere kuburemere burenze 500 HV.

Shyiramo Ibice Byuzuye Byubushyuhe: Shushanya amazu ya moteri yimodoka mu buryo bwa aluminium exoskeleton kugirango ukoreshe ibintu byinshi byogukoresha ubushyuhe (> 130 W / m · K) kugirango ukonje moteri.
