Ithonya lamaphutha emishini kwikhwalithi yama-hinges aqondile ayindilinga aguquguqukayo_achigre_talls1

Andisiwe

I-Flexible Hinge iyindlela eguquguqukayo kakhulu esebenzisa izici ze-micro-elastic deformation kanye nezimpawu zokuvuselela zensimbi. Isebenza njengendlela yokuhambisa ephezulu yokususa okuphezulu, isetshenziswa kabanzi kumadivayisi ahlukahlukene okuhlekisa okuhle, amapulatifomu wokubeka izinto ngokunemba, ama-photolithography kanye nokuhlola ama-microscopes, nokuningi. Ngenxa yokucubungula kwayo okuhlanganisiwe nokubumba, inezici eziyingqayizivele njengezingesici semishini, asikho isikhala sokukhwelana, akukho ukufukula okuphezulu.

Kodwa-ke, kunezici eziningana ezingathinta ukusebenza okusebenzayo kwama-hinges aguqukayo. Lapho kwenziwa ama-hinges aguqukayo, kwenziwa imibono ethile, njengokucabanga ukuthi ukuguquguquka kokunwebeka kuphela okwenzeka eHinge ngenkathi konke okunye kubhekwa njengomzimba oqinile. Kucatshangelwa futhi ukuthi kuphela i-deformation ekhoneni eyenzeka ngesikhathi somsebenzi, ngaphandle kokunwetshwa noma okunye ukukhubazeka. Ngaphezu kwalokho, ama-hinge uqobo anezinkinga ezenzeka, ezinjengesikhungo sokujikeleza angalungisi, ukugxilisa ingcindezi, izinguquko ezinkulu zokucindezela, izinguquko ezinkulu zokucindezela ngesikhundla sokuhlangana, kanye nethonya lemvelo elikulo.

Ekwakhiweni okuhlelekile, ukuhanjiswa okuhlanganisiwe ekhoneni kanye nomugqa oqondile kungabangelwa ukucubungula amaphutha phakathi kokuhlanganiswa kwezinduku eziningana nezinduku zokuxhuma. Lokhu kungaholela ekuphambukeni okuphambukayo kusuka kwithrekhi efanelekile. Izincwadi ezibanzi zihlaziye imithombo yephutha yezinqubo eziguqukayo ze-hinge, zixoxa ngokusebenza kwezinto ezibonakalayo, ukwakhiwa kosayizi, ukudlidliza, ukuphazamiseka, amaphutha emishini, nokuningi. Lezi zifundo zinikezela ngemininingwane ebalulekile ekusokeni kwephutha ngalinye eliguquguqukayo kanye nokuhlanganiswa kwendlela yokufuduka okubangelwa amaphutha okukhiqiza.

Leli phepha lihlose ukuhlaziya izinhlobo ezintathu zamaphutha emishini ye-stical aguquguqukayo hinge futhi uthole ifomu lokubala ukuqina lapho la maphutha ekhona. Ubukhulu be-hinge kanye namapharamitha wephutha asetshenziselwa ukubala ukuqina futhi aqinisekise imiphumela ngokuhlaziywa kwesekhi (fea). Lokhu kuhlaziywa kunikeza imininingwane ebalulekile yokwakheka kwepharamitha kanye nokucutshungulwa kwe-hinge.

Izinhlobo ezintathu zamaphutha emishini ehlaziywe kuleli phepha zifaka iphutha lokuma kwe-notch arc endaweni ye-Y, iphutha le-notch arc emugqeni we-x. Uhlobo ngalunye lwephutha luhlaziywa ngokwahlukana, futhi amaphutha wokuqina abalwa ngokususelwa kuma-coefficients wephutha namapharamitha we-hinge. Amafomula we-Stiffness ERROR ARREC aqhathaniswa futhi aqinisekiswe ngokulingisa kwe-FEA.

Imiphumela yokuhlaziywa kwamanani kanye nokulingisa kwe-FEA ikhombisa isivumelwano esihle. Ama-curves aqinile ama-curve atholwe ngaphansi kwamanani ahlukene we-hinge parameter akhombisa ukuthi ama-coefficients ephutha anomthelela omkhulu ekuqineni. Amaphutha wokuma ezinkombeni ze-Y no-X abe nethonya elikhulu, ngenkathi iphutha le-perpendicularline lithinta ukuqina. Ngokuqonda la maphutha nemiphumela yazo, ukuklama okusebenzayo kanye nezinqubo zemishini kungaqaliswa ukunciphisa umthelela wazo ku-hinge eguquguqukayo.

Ekuphetheni, amaphutha wemishini anama-hinge aguquguqukayo aqondile anomthelela oqondile ekusebenzeni kwabo ukuqina. Leli phepha lihlinzeka ngokuhlaziywa okuphelele kwezinhlobo ezintathu zamaphutha emishini futhi ziveza amafomula wokuqina wokuqina ngohlobo ngalunye lwephutha. Imiphumela iqinisekisiwe nge-Fea Simulations, igqamisa ukubaluleka kokulawula amaphutha wokuma namaphutha we-perpendicality ukuze wenze kahle ukusebenza kwama-hinges aguqukayo. Ukutholwa kwalolu cwaningo kungasebenza njengesethenjwa esibalulekile ekuklameni nezinqubo zokukhiqiza ezimbonini ezahlukahlukene.
