Ithonya lamaphutha emishini kwikhwalithi yama-hinges aqondile ayindilinga aguquguqukayo_achigre_talls

I-AFFEFFIMCE HINGE iyingxenye yemishini esebenzisa izici ezi-micro-elastic deformation kanye nezimpawu zokuvuselela zensimbi. Kuyindlela yokudluliselwa kwesinqumo esiphakeme esivumela ukuma okuqondile nokuhleleka okuhle. Isetshenziswa kakhulu kumadivayisi anjengepulatifomu yokuma okunembayo, imishini ye-Photolithography, kanye nokuhlola ama-microscopes.

Kunezici eziningana ezingathinta ukusebenza kwama-hinges aguqukayo. Lapho kwenziwa ama-hinges aguquguqukayo, kwenziwa okuthile okuthile, njengokucabanga ukuthi kuphela ukuphuma kwezimokala okwenzeka eHinge nokuthi lonke isakhiwo sonke liqinile. Kucatshangelwa futhi ukuthi kuphela ukuphuma kwe-deformation okwenzeka ngesikhathi sokusebenza, ngaphandle kokunwetshwa noma okunye ukukhubazeka. Kodwa-ke, ama-hinge ngokwawo anezinkinga ezenzeka, ezinjengesikhungo sokujikeleza angalungisi, ukugxilisa ingcindezi, kanye nezinguquko ezinkulu zokucindezela ngesikhundla sokuhlanganiswa. Izakhiwo ezibonakalayo kanye nezici zezemvelo zingathinta nokusebenza kwe-hinge.

Ekwakhiweni okuhlelekile, inhlanganisela yama-hinges amaningi kanye nezinduku zokuxhuma kuvamile. Kodwa-ke, amaphutha okucubungula phakathi kwale nhlanganisela angaholela ekuxhumaneni kwamakhona amakhona nemigqa eqondile, okwenza ukunyakaza kwendlela kuphambuke endaweni oyifunayo. Kube nokuhlaziywa okuphelele kwemithombo yephutha ezindaweni eziguqukayo ze-hinge, kufaka phakathi izingxoxo ekusebenzeni kwezinto ezibonakalayo, ukuklanywa kosayizi, ukudlidliza, ukuphazamiseka, amaphutha emishini, njll. Lokhu kuhlaziya kuhlose ukuqonda ukuzwela kwephutha ngalinye eliguquguqukayo ekusebenzeni kwe-hinge eguquguqukayo.

Ucwaningo lwangaphambilini lusebenzise izindlela ezifana nokwandiswa kochungechunge lweTaylor Series, indlela ye-Fination, kanye nokulingiswa kwezinombolo ukutadisha izindlela zokufuduka nokuhlangana okubangelwa amaphutha okukhiqiza ezindaweni eziguqukayo. Kodwa-ke, iningi lalezi zifundo ligxile ezimweni ngazinye futhi libe nemikhawulo ethile ngokuya ngobubanzi nemiphumela etholakele.

Leli phepha ligxile ekuhlaziyeni kwamaphutha amathathu emishini ezindaweni eziguquguqukayo eziyindilinga eziguquguqukayo: iphutha lokuma kwe-arc ye-incision eqondisweni ye-y, nephutha lokubeka eceleni kwe-axis ye-axis ye-X, ne-perpendicular Amafomula wokubala wokuqina wohlobo ngalunye lwephutha athathwe, futhi imiphumela iqinisekisiwe kusetshenziswa ukuhlaziywa kwe-Finate Element (FEA). Lolu cwaningo luhlinzeka ngokuqonda okubalulekile emklamweni wepharamitha kanye nokucutshungulwa kwama-hinges.

Ukuqhuba ukuhlaziywa, imodeli ye-Cantilever Beam Strading isungulwe kusetshenziswa isoftware ye-Ansys. Amaphoyinti ahlukene wokuqamba atholakala ngokushintsha amapharamitha wephutha, kanye nokubalwa kokulingisa kwenziwa kumaphoyinti wokuqamba ukuthola amaphutha wokuqina. Imiphumela etholwe ekuhlaziyweni kwamanani kanye nokuhlaziywa kwe-Finete Element kuqhathaniswa futhi kutholakale ukuthi kusesivumelwaneni esihle.

Imiphumela ikhombisa ukuthi amaphutha ekukhuliseni kwe-ARC eqondiswa e-Y kanye ne-perpendicality yomugqa we-axis banomthelela omkhulu ekuqineni kwe-hinge eguquguqukayo. Amaphutha ekukhuliseni kwe-arc enision e-X ukuqondisa abe nethonya elincane. Ngokusekelwe kulokhu okutholakele, kunconywa ukuthi kulawule ngokuqinile amaphutha wokubeka endaweni ye-Y kanye ne-perpendicality yomugqa we-axis, ngenkathi ucabanga ukunciphisa inani le-T / R ukuze unciphise umthelela wamaphutha wokubeka ku-X.

Ekuphetheni, lolu cwaningo luhlinzeka ngokuhlaziywa okuphelele kwamaphutha emishini ezindaweni ezinamakhanda aqondayo eziguquguqukayo kanye nomthelela wazo ekuqineni. Amafomula wokubala wokuqina wokuqina kanye nokuqinisekiswa kusetshenziswa ukuhlaziya okwenziwe nge-fincite kufaka isandla ekuqondeni ukwakheka kwepharamitha ye-hinge. Ucwaningo olwengeziwe lungenziwa ukuhlola ezinye izinhlobo zamaphutha emishini nemiphumela yazo ekusebenzeni kwama-hinges aguqukayo.
