Emkhakheni wokukhiqiza imishini yezokwelapha, ukunemba kokucubungula kwezingxenye zemishini ye-radiotherapy enembayo kuhlobene ngokuqondile nokusebenza kwemishini kanye nomthelela wokwelapha weziguli. Iplathifomu ye-XYZT yokunemba kwe-gantry yokunyakaza incike ezinhlelweni eziyingqayizivele zezingxenye zegwadle, enikeza isiqinisekiso esiqinile sokusika okunembile, ukubhoboza nokunye ukusebenza kwezilingisi zezicubu zomuntu.
Ukuzinza okuhle kakhulu kuqinisekisa ukuma okunembile
Ukucutshungulwa kwezingxenye zemishini yokwelapha nge-radiotherapy kudinga ukunemba kokuma okuphezulu kakhulu, futhi noma yikuphi ukuchezuka okuncane kungase kuthinte ukushiswa okunembile kwezicubu zesimila ngesikhathi sokwelashwa nge-radiotherapy. XYZT ngokunemba gantry ukunyakaza platform izingxenye granite, isakhiwo sangaphakathi aminyene futhi umfaniswano, nokusimama okuhle kakhulu. Ukuminyana kwayo kuphezulu njengokungu-2.6-2.7g/cm³, okungamelana ngempumelelo nokuphazamiseka kokudlidliza kwangaphandle, ngisho nasendaweni eyinkimbinkimbi yendawo yokusebenzela, kodwa futhi kunciphise i-amplitude yokudlidliza yeplathifomu ngaphezu kuka-80%. Lapho usika futhi umba izifanisi zezicubu zomuntu, izingxenye ze-granite zinikeza ukusekela okuqinile kweplatifomu ukuze kuqinisekiswe ukuma okunembile kwethuluzi noma ithuluzi lokusika, ngokunemba kokubeka kuze kufike ku-± 0.01mm. Isibonelo, lapho ucubungula amaqabunga e-collimator wemishini ye-radiotherapy, isikhundla nokuma kwamaqabunga kungalawulwa ngokunembile, ukuze imisebe ikwazi ukugxila ngokunembile endaweni yesimila, igweme ukulimala kwezicubu ezinempilo ezizungezile.
Ukuqina okuphezulu ukuhlangabezana nezidingo zomshini wokunemba okuphezulu
Inqubo yokusika nokubhoboza izifanisi zezicubu zomuntu inezidingo eziqinile ekuqineni kwemishini. Izingxenye ze-Granite zinokuqina okuphezulu namandla acindezelayo afinyelela ku-200-300MPa, angakwazi ukumelana namandla amakhulu okusika asetshenziswa ithuluzi enqubweni yokucubungula ngaphandle kokuguqulwa okusobala. Ngesikhathi sokusebenza kokumba kwe-simulation, isiteji singahlala sizinzile ukuvimbela ukufuduka kwendawo yokumba noma ukuphambuka kwembobo ngenxa yamandla. Endabeni yezingxenye zombhede wokwelapha wokwenziwa kwemishini ye-radiotherapy, ukumba okunembayo okuphezulu kuyadingeka entweni elingisa isakhiwo samathambo omuntu ukuze kufakwe izinto zokulungisa. Izingxenye ze-granite ze-XYZT precision gantry movement yesikhulumi zisekela ukusebenza okuzinzile kwesikhulumi, futhi iphutha lokunemba kwembobo yembobo lilawulwa ngaphakathi kwe-± 0.02mm, ukuqinisekisa ukuthi umbhede wokwelapha ungalungisa ngokunembile isikhundla sesiguli ngesikhathi sokusetshenziswa, futhi uhlangabezane nezidingo zemishini ye-radiotherapy yokubeka ngokunemba okuphezulu.
Ukuzinza kwe-thermal kugcina ukunemba komshini njalo
Enqubweni yokucubungula izingxenye zemishini yezokwelapha, ukusika ukushisa, izinguquko zokushisa kwemvelo nezinye izici zizothinta ukunemba kokucubungula. I-coefficient yokwandisa okushisayo kwegwadle iphansi kakhulu, ngokuvamile ku-5-7 × 10⁻⁶/℃, futhi usayizi ushintsha kancane kakhulu lapho izinga lokushisa lishintshashintsha. Lapho ucubungula ama-simulators wezicubu zomuntu isikhathi eside, ngisho noma izinga lokushisa le-workshop lishintshashintsha 5-10 ° C ngenxa yokusebenza kwemishini, isimo somoya kanye nezinye izizathu, isiteji esisekelwa izingxenye ze-granite sisengakwazi ukugcina usayizi ozinzile ukuze kuqinisekiswe ukuthi ukusika nokunemba kokumba akuthinteki. Isibonelo, ekusikeni okunembayo kwezinto ezilingisa izicubu ezithambile zomuntu, ukucaba nokuqedwa kwendawo yokusika kungaqinisekiswa ukuthi kuhlangabezana nezidingo zokujwayela kahle izingxenye zemishini ye-radiotherapy nezicubu zomuntu, futhi kuthuthukiswe ukuphepha nokusebenza kahle kwemishini ye-radiotherapy.
