Simulation of Hot Forging

Ukulingisa kwe-Hot Forging

Kuthunyelwe nguAdmin

I-Hot Forging iyinqubo yokwakha esetshenziselwa ukukhiqiza izingxenye zensimbi ezihlukahlukene,okuhlanganisa izingxenye zezimoto kanye ne-aerospace.Selokhu kwaba khona kusukela ngekhulu lamashumi amabili.Kodwa-ke, kunezici ezimbalwa okufanele zicatshangelwe lapho uklama inqubo yokubumba eshisayo.Lokhu kufaka phakathi ukuthengiseka kwezinto, ukusatshalaliswa kwezinga lokushisa kanye nomphumela wokusalungiswa.Ngaphezu kwalokho, i-microstructure yengxenye ehlanganisiwe kufanele ibalwe kahle.I-Hot Forging ihlanganisa amazinga okushisa aphezuluokuholela ekushintsheni okuphawulekayo kwesakhiwo endaweni engaphezulu yesiqephu somsebenzi.Ngaphezu kwalokhu, inqubo yokubumba ingase futhi ibangele ukwakheka kwezindawo ezine-oxidized.Inqubo yokubumba ivamise ukusetshenziselwa ukukhiqiza izingxenye ezinejometri eyinkimbinkimbi ye-3D.Ngakho-ke, ukunemba kwemodeli kubalulekile ekufaniseni okuphumelelayo.Ngokuvamile, izinhlobo ezintathu zezindlela zokumodela zisetshenziswa ukulingisa inqubo: amasu e-FE (Fuzzy EM), ukulandelela emuva, kanye nesici esilinganiselwe.I-Hot Forging iyinqubo yokukhiqiza ebalulekile yezingxenye ezibalulekile zokuphepha.Lokhu kungenxa yokuthi ivumela ukubunjwa kwezingxenye zensimbi ezinemithwalo ephezulu yokusebenza.Njengoba izinga lokushisa liphakeme kakhulu, lingenza kube lula ukwakheka kwensimbi ethambile futhi imelana nokuguqulwa.Kunezinhlobo ezimbili eziyinhloko zokuqamba: i-open die forging kanye ne-forging yesitolo semishini.Izibonelelo ezijwayelekile zokuqamba zingasukela kweshumi lamamilimitha ukuya kumamilimitha ambalwa.Ngenxa yalokhu, ukungafani phakathi kokufa kungabangela izinkinga ezinkulu.Ngokuya ohlotsheni lwempahla eyenziwayo, izinhlobo ezahlukene zokufa zingadingeka.Futhi, ukubumba okushisayo kungadinga izinyathelo ezengeziwe zokucubungula, njengokwelashwa kokushisa noma ukuqeda.Naphezu kokubaluleka kwakho, ukubumba okushisayo akunembile njengokubumba okubandayo.Lokhu kungenxa yokuthi ukwanda okushisayo kwempahla ngesikhathi senqubo yokubumba kungathinta ukunemba komkhiqizo oqediwe.Ngaphezu kwalokho, ukusetshenziswa kokusatshalaliswa kwezinga lokushisa okungafani nakho kungaveza izinguquko ezibalulekile ku-microstructure yengxenye ehlanganisiwe.Ngakho-ke, kubaluleke kakhulu ukuqinisekisa ukuthi insimbi ehlanganisiwe inamandla adingekayo kanye nokuqina.Ukuze ulingise inqubo yokuqamba,kufanele kusetshenziswe izindlela ezintathu zokumodela eziyisisekelo.Okokuqala, indlela yesici esinqunyelwe ingasetshenziswa ukulingisa inqubo yokwenza.Okwesibili, indlela ye-FE ingasetshenziswa ukunquma ukusatshalaliswa kwezinga lokushisa engxenyeni engumgunyathi.Okokugcina, inqubo yokulandela umkhondo yokubuyela emuva ingasetshenziswa ukuklama inqubo yokubumba eshisayo.Ukuze ubale ukusabalalisa izinga lokushisa okulungile,inqubo yokubumba kufanele yenziwe ngendlela elawulwayo.Lokhu kungenxa yokuthi kubalulekile ukucabangela okusalungiswa kanye nokushelela kwemiphetho ebukhali.Ukwengeza, ukusetshenziswa kwezinto ezikhethekile zokufa ezingamelana nokushisa okuphezulu nakho kunconywa.Olunye udaba okufanele lubhekwe ukukhethwa komshini wokwakha.Ukukhetha umshini ofanele kunethonya elikhulu ekusabalaliseni izinga lokushisa kwengxenye efojiwe.Okokugcina, kubalulekile ukucabangela izikhathi zokugcinwa nezokuthutha.Ukuze unqume izinga lokushisa elifanele lokubumba, kusetshenziswe amandla amakhulu okubumba atholakalayo.Ngesikhathi senqubo, i-forging die ingaphansi kwemithwalo ephezulu yemishini namakhemikhali.Ngale mithwalo, i-die kufanele imelane nezinhlobonhlobo zezinhlobonhlobo ezishisayo namakhemikhali.Ngaphezu kwalokho, kunezingcindezi ezibalulekile eziyinsalela.
