Kwintsimi yokuvelisa ngengqiqo, isixhobo sokulinganisa esihlakaniphile se-3D, njengesixhobo esisisiseko sokuphumeza ukuhlolwa okuchanekileyo kunye nokulawulwa komgangatho, ukuchaneka komlinganiselo kuchaphazela ngokuthe ngqo umgangatho wokugqibela wemveliso. Isiseko, njengenxalenye esisiseko yokuxhasa isixhobo sokulinganisa, ukusebenza kwayo kokuchasana nokungcangcazela yinto ephambili emisela ukuthembeka kweziphumo zokulinganisa. Kwiminyaka yakutshanje, ukusetyenziswa kwezixhobo zegranite kwisiseko se-3D yezixhobo zokulinganisa ezikrelekrele kubangele utshintsho kwishishini. Idatha ibonisa ukuba xa kuthelekiswa neziseko zentsimbi etyhidiweyo, ukushukuma kweziseko zegranite kunyuke ukuya kuthi ga kwi-83%, oku kuzisa impumelelo entsha yetekhnoloji kumlinganiselo ochanekileyo.
Iimpembelelo zokungcangcazela kwizixhobo zokulinganisa ezikrelekrele ze-3D
Isixhobo sokulinganisa esikrelekrele se-3D sifumana idatha ye-dimensional-dimensional yezinto ngokusebenzisa iteknoloji efana ne-laser scanning kunye ne-optical imaging. Abenzi boluvo kunye nezinto ezichanekileyo zamehlo ngaphakathi kuyo zinovakalelo olugqithisileyo kungcangcazelo. Kwindawo yokuvelisa imveliso, ii-vibrations eziveliswa kukusebenza kwezixhobo zoomatshini, ukuqala kunye nokumiswa kwezixhobo, kunye nokuhamba kwabasebenzi kunokuphazamisa ukusebenza okuqhelekileyo kwezixhobo zokulinganisa. Kwanongcangcazelo oluncinci lunokubangela ukuba umqa welaser uguqe okanye ilensi ingcangcazele, okukhokelela ekutenxeni kwidatha eqokelelweyo ye-dimensional emithathu kwaye ibangele iimpazamo zomlinganiso. Kumashishini aneemfuno ezichaneke kakhulu ezinje nge-aerospace kunye neetshiphusi zombane, ezi mpazamo zinokukhokelela kwiimveliso ezingekho mgangathweni kwaye zide zichaphazele uzinzo lwenkqubo yokuvelisa.
Imida yokumelana nokungcangcazela kweziseko zentsimbi
Intsimbi yentsimbi ibisoloko iyinto esetyenziswa ngokuqhelekileyo kwisiseko sezixhobo zokulinganisa ezikrelekrele ze-3D zemveli ngenxa yexabiso eliphantsi kunye nokulula kokusetyenzwa kunye nokubumba. Nangona kunjalo, ulwakhiwo lwangaphakathi lwentsimbi etyhidiweyo luqulethe iipores ezincinci kwaye ulungelelwaniso lwekristale lukhululekile, nto leyo eyenza kube nzima ukuba ithobe amandla ngokufanelekileyo ngexesha lenkqubo yokuhambisa i-vibration. Xa ukushukuma kwangaphandle kuhanjiswa kwisiseko sentsimbi, amaza okugubha aya kubonakalisa ngokuphindaphindiweyo kwaye asasaze ngaphakathi kwesiseko, enze i-resonance phenomenon eqhubekayo. Ngokwedatha yovavanyo, kuthatha i-avareji malunga ne-600 millisecond kwisiseko sentsimbi ukuthobisa ngokupheleleyo ukungcangcazela kwaye ubuyele kwisimo esizinzileyo emva kokuphazamiseka. Ngethuba le nkqubo, ukuchaneka kokulinganisa kwesixhobo sokulinganisa kuchaphazeleka kakhulu, kwaye impazamo yokulinganisa ingaba phezulu njenge-± 5μm.
I-anti-vibration inzuzo yeziseko zegranite
I-Granite lilitye lendalo elenziwe ngenkqubo ye-geological kumakhulu ezigidi zeminyaka. Iikristale zayo zangaphakathi zamaminerali zixinene, isakhiwo sixinene kwaye siyafana, kwaye sinokumelana nokungcangcazela okugqwesileyo. Xa ii-vibrations zangaphandle zithunyelwa kwisiseko se-granite, i-microstructure yayo yangaphakathi inokuguqula ngokukhawuleza amandla okugubha kumandla obushushu, ukufezekisa ukuthotywa okusebenzayo. Idatha yovavanyo ibonisa ukuba emva kokuba phantsi kokuphazamiseka okufanayo kwe-vibration, isiseko segranite sinokuphinda sibuyisele uzinzo malunga ne-100 milliseconds, kunye nokusebenza kwayo kokuchasana nokungcangcazela kubhetele kakhulu kunoko kwesiseko sentsimbi, kunye ne-83% yokuphucula ukusebenza kwe-anti-vibration xa kuthelekiswa nentsimbi.
Ukongeza, ipropathi ephezulu yokumanzisa yegranite iyenza ikwazi ukufunxa ngokufanelekileyo ukungcangcazela kweefrikhwensi ezahlukeneyo. Ingaba i-high-frequency machine tool vibration okanye i-low-frequency ground vibration, isiseko segranite sinokunciphisa impembelelo yabo kwisixhobo sokulinganisa. Kwizicelo eziphathekayo, isixhobo sokulinganisa esihlakaniphile se-3D esinesiseko segranite sinokulawula impazamo yokulinganisa ngaphakathi kwe-± 0.8μm, ephucula kakhulu ukuchaneka nokuthembeka kwedatha yokulinganisa.
Izicelo zoShishino kunye neZibonelelo zexesha elizayo
Ukusetyenziswa kweziseko zegranite kwi-3D yezixhobo zokulinganisa ezihlakaniphile kubonise inzuzo ebalulekileyo kwiindawo ezininzi zokuvelisa eziphezulu. Kwimveliso yeetshiphusi ze-semiconductor, isiseko segranite sinceda isixhobo sokulinganisa amandla sifezekiseke ngokuchaneka okuphezulu kobungakanani kunye nokumila kweechips, ukuqinisekisa umlinganiselo wesivuno sokwenziwa kwetshiphu. Ekuhlolweni kwamacandelo e-aerospace, ukusebenza kwayo okuzinzileyo kokuchasana nokungcangcazela kuqinisekisa umlinganiselo ochanekileyo wamacandelo omhlaba ogobileyo onzima, unikezela isiqinisekiso sokusebenza ngokukhuselekileyo kweenqwelomoya.
Ngokuphuculwa okuqhubekayo kweemfuno ezichanekileyo kwishishini lokuvelisa, amathuba okusetyenziswa kweziseko zegranite kwintsimi ye-3D yezixhobo zokulinganisa ezihlakaniphile zibanzi. Kwixesha elizayo, ngokuqhubela phambili okuqhubekayo kwenzululwazi yemathiriyeli kunye nobuchwepheshe bokusetyenzwa, isiseko segranite siya kuphuculwa ngakumbi kuyilo, sibonelela ngenkxaso eyomeleleyo yokuphucula ukuchaneka kwezixhobo zokulinganisa ezikrelekrele ze-3D kunye nokukhuthaza ushishino lokuvelisa olukrelekrele ukuya kwinqanaba eliphezulu.
