Kwicandelo lokuvelisa ngokuchanekileyo kunye nokuhlolwa komgangatho, umatshini wokulinganisa onamakhonkco amathathu sesona sixhobo siphambili sokuqinisekisa ukuchaneka kwemveliso. Ukuchaneka kwedatha yawo yokulinganisa kuchaphazela ngokuthe ngqo umgangatho wemveliso kunye nokwenza ngcono iinkqubo zemveliso. Nangona kunjalo, impazamo yokuguqulwa kobushushu ebangelwa kukutshintsha kobushushu ngexesha lokusebenza kwezixhobo ibisoloko iyingxaki enzima echaphazela eli shishini. Isiseko segranite, esineempawu zayo ezibonakalayo kunye neenzuzo zesakhiwo, siye saba sisitshixo sokususa impazamo yokuguqulwa kobushushu yomatshini wokulinganisa onamakhonkco amathathu.
Izizathu kunye neengozi zeempazamo zokuguqulwa kobushushu kwiimashini zokulinganisa ezintathu
Xa umatshini wokulinganisa onama-three coordinate usebenza, ukusebenza kwemoto, ubushushu obuvelisa ukungqubana, kunye nokuguquguquka kobushushu bendalo konke oku kunokubangela utshintsho kubushushu bezixhobo. Isiseko somatshini wokulinganisa esenziwe ngezinto zesinyithi zemveli sinomlinganiselo ophezulu wokwandiswa kobushushu. Umzekelo, umlinganiselo wokwandiswa kobushushu bentsimbi eqhelekileyo umalunga ne-11×10⁻⁶/℃. Xa ubushushu bunyuka nge-10℃, isiseko sesinyithi esibude bemitha e-1 siya kwanda nge-110μm. Olu tshintsho luncinci luya kudluliselwa kwiprobe yokulinganisa ngesakhiwo somatshini, nto leyo ebangela ukuba indawo yokulinganisa itshintshe kwaye ekugqibeleni ibangele iimpazamo kwidatha yokulinganisa. Ekuhlolweni kweendawo ezichanekileyo, ezinje ngee-blades zenjini ye-aero kunye nee-molds ezichanekileyo, impazamo ye-0.01mm inokukhokelela ekungahambelani kwemveliso. Iimpazamo zokuguqulwa kobushushu zichaphazela kakhulu ukuthembeka kokulinganisa kunye nokusebenza kakuhle kwemveliso.
Iingenelo ezikhethekileyo zeziseko zegranite
I-coefficient ephantsi kakhulu yokwandiswa kobushushu, isalathiso sokulinganisa esizinzileyo
I-Granite lilitye lendalo eliyi-igneous elenziwe ngeenkqubo zejoloji kwiminyaka engamakhulu ezigidi. I-coefficient yayo yokwandiswa kobushushu iphantsi kakhulu, idla ngokuqala kwi-(4-8) ×10⁻⁶/℃, eyi-1/3 ukuya kwi-1/2 kuphela yezixhobo zesinyithi. Oku kuthetha ukuba phantsi kotshintsho olufanayo lobushushu, utshintsho lobungakanani besiseko se-granite luncinci kakhulu. Xa ubushushu obujikelezayo butshintshatshintsha, isiseko se-granite sinokugcina imo yejometri ezinzileyo, sibonelela ngereferensi eqinileyo yenkqubo yokulungelelanisa yomatshini wokulinganisa, siphephe ukuphambuka kwesikhundla seprobe yokulinganisa okubangelwa kukuguquguquka kwesiseko, kwaye sinciphise impembelelo yeempazamo zokuguquguquka kobushushu kwiziphumo zokulinganisa ezivela kwingcambu.
Ukuqina okuphezulu kunye nesakhiwo esifanayo thintela ukudluliselwa kwe-deformation
I-granite iqinile ngokwendlela ebukeka ngayo, inesakhiwo sekristale yangaphakathi esixineneyo nesifanayo, kwaye ubunzima bayo bunokufikelela kwi-6-7 kwisikali se-Mohs. Olu kuqina luphezulu lwenza ukuba isiseko se-granite singabi nakwenzeka ukuba siguqulwe sibe yi-elastic xa sithwele ubunzima bomatshini wokulinganisa ngokwawo kunye namandla angaphandle ngexesha lenkqubo yokulinganisa. Nokuba ukusebenza kwezixhobo kuvelisa ukungcangcazela okuncinci okanye amandla angalinganiyo endawo, isiseko se-granite sinokucinezela ngempumelelo ukudluliselwa kunye nokusasazwa kokuguquguquka ngeempawu zaso ezifanayo zesakhiwo, kuthintelwe ukuguquguquka ukuba kuqhutywe ukusuka kwisiseko ukuya kwindlela yokulinganisa, kuqinisekiswe ukuba i-probe yokulinganisa ihlala ikwimeko yokusebenza ezinzileyo, kwaye kuqinisekiswe ukuchaneka kwedatha yokulinganisa.
Ukusebenza kokunciphisa ubushushu ngokwendalo, ukufunxa ukungcangcazela nobushushu
Isakhiwo esikhethekileyo segranite siyinika ukusebenza okugqwesileyo kokufunxa. Xa ukungcangcazela okuveliswa kukusebenza komatshini wokulinganisa kudluliselwa kwisiseko segranite, amasuntswana angaphakathi eeminerali kunye neembobo ezincinci zinokuguqula amandla okufunxa abe ngamandla obushushu kwaye ziwasebenzise, zinciphise ngokukhawuleza ubukhulu bokungcangcazela. Okwangoku, olu phawu lokufunxa lukwanceda ekufunxeni ubushushu obuveliswa kukusebenza kwezixhobo, lunciphise izinga lokuqokelelwa kunye nokusasazwa kobushushu kwisiseko, kwaye lunciphise umngcipheko wokuguqulwa kobushushu bendawo okubangelwa kukusasazwa kobushushu obungalinganiyo. Kwimisebenzi yokulinganisa eqhubekayo ixesha elide, ukusebenza kokufunxa kwesiseko segranite kunokunciphisa kakhulu ukwenzeka kweempazamo zokuguqulwa kobushushu kwaye kuphucule uzinzo lokulinganisa.
Isiphumo sokusetyenziswa okusebenzayo kwesiseko segranite
Emva kokuba amashishini amaninzi okuvelisa etshintshe isiseko sesinyithi somatshini wokulinganisa ii-three-coordinate ngesiseko se-granite, ukuchaneka kokulinganisa kwaphucuka kakhulu. Emva kokuba ishishini elithile lokuvelisa iinxalenye zeemoto lizise umatshini wokulinganisa ii-three-coordinate onesiseko se-granite, impazamo yokulinganisa ibhloko yenjini yancitshiswa ukusuka kwi-±15μm yokuqala ukuya kwi-±5μm. Ukuphindaphinda kunye nokuphindaphinda kwedatha yokulinganisa kwaphucuka kakhulu, ukuthembeka kokuhlolwa komgangatho wemveliso kwaphucuka, kwaye izinga lokugweba kakubi kwemveliso elibangelwe ziimpazamo zokulinganisa lancitshiswa ngempumelelo. Iphucule ukusebenza kakuhle kwemveliso kunye nokukhuphisana kwamashishini.
Ukuqukumbela, isiseko segranite, esine-coefficient ephantsi kakhulu yokwandiswa kobushushu, ubulukhuni obuphezulu, ulwakhiwo olufanayo kunye nokusebenza kakuhle kokudambisa, sisusa impazamo yokuguqulwa kobushushu bomatshini wokulinganisa onama-three-coordinate kwiimilinganiselo ezahlukeneyo, sibonelela ngenkxaso esisiseko ezinzileyo nethembekileyo yokulinganisa ngokuchanekileyo, kwaye sibe yinxalenye ebalulekileyo yezixhobo zokulinganisa ezichanekileyo zanamhlanje.
