Ndi zinthu ziti zomwe zili bwino panjinga zamagetsi zamagetsi?

M'dziko lamakono,mipando yamagetsi yamagetsi, monga njira yoyendera pang'onopang'ono yomwe ikubwera, yadziwika pang'onopang'ono ndi okalamba ambiri ndi olumala. Ndi kupita patsogolo kwa anthu ndi chitukuko cha sayansi ndi teknoloji, mitundu ndi masanjidwe a mipando yamagetsi yamagetsi yakhala Yowonjezereka, ponena za zipangizo zokha, pali mitundu yambiri, monga carbon steel, aluminiyamu alloy, magnesium alloy, ndi apamwamba. -grade carbon CHIKWANGWANI, Azamlengalenga titaniyamu zotayidwa aloyi, etc. Choncho tikayang'anizana ndi zipangizo zosiyanasiyana, ife Momwe kusankha njinga yamagetsi yamagetsi yotsika mtengo? Ndi zinthu ziti zomwe zili bwino panjinga zamagetsi zamagetsi?

Choyamba, zomwe tiyenera kudziwa ndikuti gulu lililonse ndi momwe amagwiritsira ntchito komanso malo ogwiritsira ntchito ndizosiyana, zomwe zimabweretsanso kusiyanitsa kwa zinthu zogulidwa. Pakufunidwa kosiyanaku, tikukupatsani kuchokera kuzinthu zotsatirazi Malingaliro ndi mafotokozedwe ena.

Zida wamba zimagawidwa kukhala zitsulo za kaboni, zitsulo zotayidwa, aloyi yazamlengalenga titaniyamu ndi aloyi ya magnesium. Sitidzalankhula za kaboni fiber pakadali pano (mtengo wapamwamba ndi ntchito zochepa);

1. Chitsulo cha carbon:

Mafelemu achitsulo cha kaboni amagwiritsidwa ntchito makamaka panjinga zolemetsa zolemetsa komanso mitundu ina yopangidwa ndi mafakitale ang'onoang'ono. Ma wheelchair olemetsa amagwiritsa ntchito mafelemu achitsulo kuti alimbikitse kulimba kwa thupi komanso kuyendetsa bwino. Mwachitsanzo, mafelemu a magalimoto akuluakulu ambiri amakhala zitsulo. Pachifukwa chomwecho, magalimoto amatha kugwiritsa ntchito aluminiyamu. Zipando zamagudumu zopangidwa m'mafakitale ang'onoang'ono zimagwiritsa ntchito mafelemu achitsulo chifukwa izi zimafuna njira zochepetsera komanso zowotcherera ndipo ndizotsika mtengo kumanga.

2. Aluminiyamu aloyi & titaniyamu zotayidwa aloyi

Aluminiyamu aloyi ndi titaniyamu-aluminiyamu aloyi, mafelemu awiriwa amatenga gawo lalikulu pamsika wama wheelchair. Ndi mitundu iwiri yosiyana ya aluminiyamu, 7001 ndi 7003, zomwe zikutanthauza kuti zipangizo zina zosakanikirana zimawonjezeredwa ku zipangizo za aluminiyamu. Zopangidwa ndi zitsulo zosapanga dzimbiri, zomwe zimafanana ndizochepa kwambiri komanso mphamvu zambiri, kukana kwapulasitiki komanso kukana dzimbiri. Kufotokozera momveka bwino, ndizopepuka, zamphamvu komanso zosavuta kuzikonza, pomwe titaniyamu-aluminium alloy imakhala ndi mphamvu zambiri komanso kukana dzimbiri. Amagwiritsidwa ntchito kwambiri pazamlengalenga, motero amatchedwanso aerospace titanium aluminium alloy. Chifukwa titaniyamu ili ndi malo osungunuka kwambiri, omwe amatha kufika madigiri a 1942, omwe ndi oposa 900 madigiri apamwamba kuposa golide, kukonza kwake ndi kuwotcherera kwake kumakhala kovuta kwambiri. Sizingapangidwe ndi mafakitale ang'onoang'ono opangira zinthu, kotero kuti titaniyamu aluminiyamu yoyendetsa ndege imakwera ma Wheelchairs opangidwa ndi alloy ndi okwera mtengo kwambiri. Posankha kugula, choyambiriracho ndi choyenera kwa ogwiritsa ntchito omwe amawagwiritsa ntchito pafupipafupi, misewu yabwino komanso malo oyendetsa galimoto, pomwe ogwiritsa ntchito pafupipafupi, kuyenda pafupipafupi, komanso kuyendetsa galimoto pafupipafupi m'maenje ndi misewu yopingasa amatha kusankha mipando yamtundu wa titaniyamu-aluminium alloy. . .

3. Magnesium aloyi

Magnesium alloy ndi aloyi yochokera ku magnesium ndikuwonjezeredwa ndi zinthu zina. Makhalidwe ake ndi: kachulukidwe kakang'ono, mphamvu yayikulu, modulus yayikulu yotanuka, kutentha kwabwino, kuyamwa kwabwino, komanso kutha kupirira katundu wazotengera kuposa ma aluminiyamu aloyi. Masiku ano, ma aloyi a magnesium-aluminium amagwiritsidwa ntchito kwambiri. Ndichitsulo chopepuka pakati pa zitsulo zothandiza. Mphamvu yokoka ya magnesium ndi pafupifupi 2/3 ya aluminiyamu ndi 1/4 yachitsulo. Cholinga chogwiritsira ntchito magnesium alloy pa chimango cha olumala ndikukwaniritsa kulemera kopepuka kutengera aluminum alloy. quantification" cholinga.

Pamwambapa pali zinthu zingapo wamba chimango cha olumala. Mutha kusankha molingana ndi malo omwe mumagwiritsa ntchito komanso momwe mulili.
