Kwintsimi yokwenziwa ngokuchanekileyo kunye nokuhlolwa komgangatho, umatshini wokulinganisa ulungelelwaniso ezintathu sisixhobo esisisiseko sokuqinisekisa ukuchaneka kwemveliso. Ukuchaneka kwedatha yokulinganisa kwayo kuchaphazela ngokuthe ngqo umgangatho wemveliso kunye nokulungiswa kweenkqubo zokuvelisa. Nangona kunjalo, impazamo ye-thermal deformation ebangelwa utshintsho lweqondo lokushisa ngexesha lokusebenza kwezixhobo ihlala iyingxaki enzima ephazamisa ishishini. Isiseko se-granite, esineempawu ezibonakalayo ezibonakalayo kunye neenzuzo zesakhiwo, sibe ngundoqo ekupheliseni impazamo ye-thermal deformation yomatshini wokulinganisa ezintathu.
Izizathu kunye neengozi zeempazamo zokuguqulwa kwe-thermal kumatshini wokulinganisa ukulungelelanisa ezintathu
Xa umatshini wokulinganisa onemigangatho emithathu usebenza, ukubaleka kwemoto, ukukhuhlana okuvelisa ubushushu, kunye nokuguquguquka kobushushu bendalo yonke kunokubangela utshintsho kubushushu besixhobo. Isiseko somatshini wokulinganisa owenziwe ngezinto zetsimbi zendabuko zine-coefficient ephezulu yokwandiswa kwe-thermal. Ngokomzekelo, i-coefficient yokwandiswa kwe-thermal yentsimbi eqhelekileyo imalunga ne-11 × 10⁻⁶/℃. Xa iqondo lobushushu linyuka nge-10℃, isiseko sesinyithi esinemitha e-1 ubude siya kunyuka nge-110μm. Olu tshintsho oluncinci luya kudluliselwa kwiprobe yokulinganisa ngesakhiwo somatshini, okwenza ukuba indawo yokulinganisa itshintshe kwaye ekugqibeleni ibangele iimpazamo kwidatha yokulinganisa. Ekuhlolweni kwamacandelo achanekileyo, anje nge-injini ye-aero blades kunye nokubumba okuchanekileyo, impazamo ye-0.01mm inokukhokelela ekungahambelani kwemveliso. Iimpazamo ze-thermal deformation zichaphazela kakhulu ukuthembeka komlinganiselo kunye nokusebenza kakuhle kwemveliso.
Iinzuzo zeempawu zeziseko zegranite
I-Ultra-low coefficient yokwandiswa kwe-thermal, ireferensi yomlinganiselo ozinzileyo
Igranite lilitye lendalo elivuthayo elenziwe ngenkqubo yejoloji kwisithuba esingamakhulu ezigidi zeminyaka. I-coefficient yayo yokwandiswa kwe-thermal iphantsi kakhulu, ngokuqhelekileyo ukusuka kwi-(4-8) × 10⁻⁶/℃, eyi-1/3 kuphela kwi-1/2 yezinto zensimbi. Oku kuthetha ukuba phantsi kwenguqu efanayo yeqondo lokushisa, utshintsho lobungakanani besiseko segranite sincinci kakhulu. Xa iqondo lobushushu ambient eguquguqukayo, isiseko granite unako ukugcina imilo yejiyometri ezinzile, inika isalathiso esiluqilima inkqubo ulungelelwaniso umatshini wokulinganisa, ukuphepha ukutenxa isikhundla sokulinganisa probe okubangelwa deformation isiseko, kunye nokunciphisa impembelelo yeempazamo deformation thermal kwiziphumo umlinganiselo ukusuka ingcambu.
Ukuqina okuphezulu kunye nesakhiwo esifanayo sicinezela ukuhanjiswa kwe-deformation
I-Granite inzima kwi-texture, kunye ne-dense and uniform internal structure crystal crystal, kwaye ubunzima bayo bunokufikelela kwi-6-7 kwisikali se-Mohs. Oku kuqina okuphezulu kwenza isiseko se-granite sincinci ukuba singene kwi-elastic deformation xa sithwala ubunzima bomatshini wokulinganisa ngokwawo kunye namandla angaphandle ngexesha lenkqubo yokulinganisa. Nangona umsebenzi wesixhobo uvelisa ukungcangcazela okuncinci okanye amandla angalinganiyo asekuhlaleni, isiseko segranite sinokucinezela ngokufanelekileyo ukuhanjiswa kunye nokusabalalisa kwe-deformation kunye neempawu zayo zesakhiwo esifanayo, ukuthintela ukuguqulwa kuqhutywe ukusuka kwisiseko ukuya kwindlela yokulinganisa, ukuqinisekisa ukuba i-probe yokulinganisa ihlala ikwimeko esebenzayo, kwaye iqinisekisa ukuchaneka kwedatha yokulinganisa.
Ukusebenza kokudambisa kwendalo, ukufunxa ukungcangcazela kunye nobushushu
I-microstructure ekhethekileyo yegranite iyinika umsebenzi obalaseleyo wokudambisa. Xa i-vibration eyenziwa ngokusebenza komatshini wokulinganisa idluliselwa kwisiseko se-granite, iincinci zangaphakathi zamaminerali kunye neepore ezincinci ziyakwazi ukuguqula amandla okugubha kumandla obushushu kwaye zidle, ngokukhawuleza zinciphisa i-vibration amplitude. Ngeli xesha, olu phawu lokuthomalalisa lukwanceda ukufunxa ubushushu obuveliswa kukusebenza kwesixhobo, ukucotha isantya sokuqokelelwa kunye nokusasazwa kweqondo lobushushu kwisiseko, kunye nokunciphisa umngcipheko wokuguqulwa kwe-thermal yendawo okubangelwa kukusasazwa kobushushu obungalinganiyo. Kwimisebenzi eqhubekayo yokulinganisa ixesha elide, ukusebenza okumanzi kwesiseko segranite kunokunciphisa kakhulu ukwenzeka kweempazamo zokuguqulwa kwe-thermal kunye nokuphucula ukuzinza komlinganiselo.
Isiphumo esisebenzayo sokusetyenziswa kwesiseko segranite
Emva kokuba amashishini amaninzi okuvelisa athathe indawo yesiseko sesinyithi somtshini wokulinganisa ulungelelwaniso oluthathu kunye nesiseko segranite, ukuchaneka komlinganiselo kwaphuculwa kakhulu. Emva kokuba ishishini elithile elenza iinxalenye zemoto lazise umatshini wokulinganisa onezilungelelanisi-ntathu oxhotyiswe ngesiseko segranite, impazamo yomlinganiselo webhloko ye-injini iye yancitshiswa ukusuka kweyokuqala ±15μm ukuya ku-±5μm. Ukuphinda-phinda kunye nokuveliswa kwakhona kwedatha yokulinganisa kuye kwaphuculwa kakhulu, ukuthembeka kokuhlolwa komgangatho wemveliso kuye kwaphuculwa, kwaye izinga lokugwetywa kwemveliso okubangelwa iimpazamo zokulinganisa kwancitshiswa ngokufanelekileyo. Iphucule impumelelo yemveliso kunye nokhuphiswano lwamashishini.
Ukuqukumbela, isiseko segranite, esine-coefficient ephantsi kakhulu yokwandiswa kwe-thermal, ukuqina okuphezulu, ukwakheka okufanayo kunye nokusebenza okugqwesileyo kokuthomalalisa, kuphelisa impazamo yokuguqulwa kwe-thermal yomatshini wokulinganisa ulungelelwaniso oluthathu ukusuka kwimilinganiselo emininzi, ukubonelela ngenkxaso esisiseko ezinzileyo nethembekileyo yokulinganisa ngokuchanekileyo, kwaye iye yaba yinto ebaluleke kakhulu kwisixhobo sokulinganisa okuphezulu.
