I-Granite vs. I-Cast Iron: Ukutyhila i-Thermal Deformation Differences yeSiseko seSiseko soMlinganiso oMathathu oLungelelaniso kunye noMfanekiso weThermal.

Kwintsimi yokulinganisa ngokuchanekileyo, umatshini wokulinganisa ulungelelwaniso oluthathu luyisixhobo esisisiseko sokulawula umgangatho wemveliso, kwaye isiseko sisebenza njengesiseko sokusebenza kwayo okuzinzile. Ukusebenza kwayo kwe-thermal deformation inquma ngokuthe ngqo ukuchaneka komlinganiselo. I-Granite kunye nentsimbi etyhidiweyo, njengezixhobo ezibini ezisisiseko, ziye zatsala ingqalelo enkulu kwiiyantlukwano zabo kwi-thermal deformation. Ngobuchwephesha bokubona ubuchwephesha bemifanekiso eshushu, sinokutyhila ngokuthe ngqo umahluko obalulekileyo kuzinzo lwe-thermal phakathi kwezi zimbini, ukubonelela ngesiseko senzululwazi sokukhethwa kwezixhobo kushishino oluchanekileyo lokuvelisa.

Ukuguqulwa kweThermal: "Umbulali ongabonakaliyo" ochaphazela ukuchaneka koMlinganiso olungelelanisiweyo
Umatshini wokulinganisa ulungelelwaniso-ntathu ufumana idatha ye-three-dimensional ngokusebenzisa uqhagamshelwano lweprobe kunye nento elinganiswayo. Nayiphi na i-thermal deformation yesiseko iya kubangela ukuba ireferensi yokulinganisa itshintshe. Kwimeko yoshishino, izinto ezifana nokuveliswa kobushushu ngexesha lokusebenza kwesixhobo kunye nokuguquguquka kweqondo lobushushu lokusingqongileyo konke kunokubangela ukwanda kwe-thermal okanye ukucutheka kwesiseko. Ukuguqulwa okuncinci kwe-thermal kunokubangela ukuphambuka kwendawo kwiprobe yokulinganisa, ekugqibeleni kukhokelela kwiimpazamo zokulinganisa. Kumashishini aneemfuno ezichaneke kakhulu ezinje nge-aerospace kunye ne-semiconductors, iimpazamo ezibangelwa yi-thermal deformation zingakhokelela ekukhutshweni kwemveliso okanye ukuthotywa kokusebenza. Ngoko ke, ukuzinza kwe-thermal yesiseko kubaluleke kakhulu.
Umfanekiso oshushu: Ubona umahluko kwi-thermal deformation
Imifanekiso ye-Thermal inokuguqula ukuhanjiswa kobushushu kumphezulu wento ibe yimifanekiso ebonakalayo. Ngokuhlalutya utshintsho lweqondo lokushisa kwiindawo ezahlukeneyo, banokubonisa ngokubonakalayo imeko ye-thermal deformation. Kuvavanyo, sikhethe i-granite kunye nentsimbi yentsimbi elungelelanisiweyo emithathu yokulinganisa iziseko zenkcazo efanayo, silinganisa ukuveliswa kobushushu ngexesha lokusebenza kwesixhobo esiphantsi kwendawo enye, kwaye sasebenzisa umfanekiso oshushu ukurekhoda utshintsho lobushushu kunye neenkqubo zokutshintsha ubushushu kuzo zombini.
Isiseko sentsimbi yokuphosa: Ukuguqulwa okubalulekileyo kwe-thermal kunye nokuzinza okuxhalabisayo
Umfanekiso we-thermal imaging ubonisa ukuba emva kokuba isiseko sentsimbi sisebenze imizuzu engama-30, kukho ukusabalalisa okungalinganiyo kobushushu bomhlaba. Ngenxa yokungalingani kwe-thermal conductivity yensimbi etyhidiweyo, iqondo lokushisa kwindawo yendawo yesiseko likhuphuka ngokukhawuleza, kwaye umahluko phakathi kweqondo lokushisa eliphezulu kunye nelona liphantsi linokufikelela kwi-8-10 ℃. Ngaphantsi kwesenzo soxinzelelo lwe-thermal, isiseko sensimbi esityhidiweyo sifumana i-deformations encinci ebonakalayo kwiso lenyama. Kwafunyaniswa ngezixhobo zokulinganisa ezichanekileyo ezichanekileyo ukuba utshintsho kwisayizi yalo yomgca lufikelele kwi-0.02-0.03mm. Olu tshintsho lunokubangela ukuba impazamo yomlinganiselo yande iye kuthi ga kwi-±5μm, ichaphazele ngokunzulu ukuchaneka komlinganiselo. Ukongeza, emva kokuba isiseko sentsimbi siyeke ukusebenza, ubushushu buyaphela kancinci kwaye kuthatha ixesha elingange-1 ukuya kwiiyure ezi-2 ukubuyela kwimeko yokuqala, nto leyo inciphisa kakhulu amandla okusebenza okuqhubekayo kwesixhobo.
Isiseko seGranite: Ukuzinza okugqwesileyo kwe-thermal kuqinisekisa ukuchaneka komlinganiselo
Ngokwahlukileyo, isiseko segranite sibonisa ukuzinza okuhle kakhulu kwe-thermal ngexesha lokusebenza. Imifanekiso ye-Thermal imaging ibonisa ukuba ukuhanjiswa kweqondo lokushisa kumphezulu kufana. Emva kweyure enye yokusebenza, umahluko omkhulu wobushushu kwisiseko somgangatho yi-1-2 ℃ kuphela. Oku kubangelwe kwi-coefficient ephantsi kakhulu yokwandiswa kwe-thermal yegranite (5-7 × 10⁻⁶/℃) kunye nokufana kwayo okuhle kakhulu kwe-thermal conductivity. Emva kokuvavanya, ukuhluka komgca we-linear dimensional base granite phantsi kweemeko ezifanayo zokusebenza zingaphantsi kwe-0.005mm, kwaye impazamo yokulinganisa inokulawulwa ngaphakathi kwe-± 1μm. Nangona emva kokusebenza kwexesha elide eliqhubekayo, isiseko segranite sisakwazi ukugcina imilo ezinzileyo, kwaye emva kokuyeka ukusebenza, ubushushu bubuyela ngokukhawuleza kwisimo esizinzile, sinika ireferensi ethembekileyo yokulinganisa okulandelayo.

Ngomboniso ocacileyo kunye nokuthelekiswa kwedatha yomfanekiso we-thermal, inzuzo yegranite kwi-thermal stability ibonakala. Kumashishini okuvelisa alandela umlinganiselo ophezulu wokuchaneka, ukukhetha umatshini wokulinganisa ukulungelelanisa ezintathu kunye nesiseko segranite kunokunciphisa ngokufanelekileyo iimpazamo zokulinganisa ezibangelwa ukuguqulwa kwe-thermal kunye nokuphucula ukuchaneka kunye nokusebenza kakuhle kokuhlolwa kwemveliso. Ngoshishino lokuvelisa oluya kufikelela ekuchanekeni okuphezulu kunye nobukrelekrele, iziseko zegranite, kunye nokuzinza kwazo okubalaseleyo kwe-thermal, zibopheleleke ukuba zibe yeyona nto ikhethwayo koomatshini bokulinganisa abalungelelanisiweyo abathathu kunye nezixhobo ezichanekileyo ngakumbi, ukuqhuba umgangatho wolawulo lweshishini ukuya kwindawo entsha.
