Ubuchwepheshe be-Ultrasonic buye basetshenziswa kabanzi ensimbi, inqubo yokushisela ipulasitiki.Ngenxa yezidingo zayo eziphezulu zokusebenza ku-dynamics yesakhiwo, izindlela zokuklama zendabuko zokulingisa nokulungisa isikhunta azisakwazi ukuzivumelanisa nezidingo eziguqukayo zemikhiqizo yepulasitiki.Leli phepha liqala ngomgomo wokuthiwelding ultrasonic plastic, iqhuba imvamisa yemvelo kanye nokuhlaziywa kwe-modal ngokusebenzisa indlela yesici esilinganiselwe, idizayina amathuluzi amasha, ihlangabezana nokudlulisa okusebenzayo kanye nezidingo zomsebenzi wamandla wokudlidliza wokusabalalisa okufanayo.Enqubweni yokuklama kuhlanganiswe ne-ANSYS parametric modelling, isici sokwenziwa ngcono komklamo wokuhlola (DOE) kanye nemojula yesistimu yokuklama okungenzeka (PDS), umklamo wamapharamitha nomklamo oqinile, lungisa usayizi wejometri, ukwenza amathuluzi kanye nemvamisa engokwemvelo i-ultrasonic frequency match, i-modal amplitude ehambisanayo ngokulinganayo ebusweni, inciphisa inkinga yesakhiwo sendawo yokuhlushwa kokucindezeleka, Ngesikhathi esifanayo, inokuvumelana nezimo ezinhle ekushintsheni kwezinto ezibonakalayo kanye nemingcele yemvelo.Okuklanyiweamathuluzi e-ultrasonicingasetshenziswa ngemva kokucutshungulwa okukodwa, okugwema ukumosha isikhathi nezindleko ezibangelwa ukugqoka kwamathuluzi okuphindaphindiwe.
Njengokuxhumana kokuxhumana phakathi kwei-ultrasonic welder yepulasitikikanye nezinto ezibonakalayo, umsebenzi oyinhloko wekhanda lethuluzi le-ultrasonic ukudlulisa ukudlidliza komshini we-longitudinal kusuka kusiguquli se-amplitude kuya ezintweni ngokulinganayo nangempumelelo.Izinto ezisetshenziswayo ngokuvamile ziyi-alloy yekhwalithi ephezulu ye-aluminium noma i-titanium alloy.Ngenxa yokuthi ukwakheka kwezinto zepulasitiki kuyashintsha, ukubukeka kwezinkulungwane ezahlukene, inhloko yamathuluzi nayo izoshintsha.Ukuma kobuso obusebenzayo kufanele kuhambisane kahle nezinto ezibonakalayo, ukuze ungalimazi ipulasitiki lapho udlidliza;Ngesikhathi esifanayo, imvamisa ehleliwe ye-vibration yokuqala ye-longitudinal kufanele ihambisane nemvamisa yokuphuma komshini wokushisela, ngaphandle kwalokho amandla okudlidliza azosetshenziswa ngaphakathi.Uma ikhanda lamathuluzi lidlidliza, ukugxiliswa kwengcindezi yendawo kuzokwenziwa.Indlela yokuthuthukisa lezi zakhiwo zendawo nayo iyinkinga okufanele icatshangelwe ekwakhiweni.Leli phepha lidingida indlela yokusebenzisa inhloko yethuluzi lokuklama le-ANSYS ukuze kuthuthukiswe imingcele yedizayini.
Umklamo weuphondo lwe-welding kanye nesicizibaluleke kakhulu.Baningi basekhayaabahlinzeki bemishini ye-ultrasonicukukhiqiza ama-welders abo, kodwa ingxenye enkulu yabo kukhona ukulingisa okukhona, bese begqokisa njalo ukugqoka, ukuhlola, ngale ndlela yokulungiswa okuphindaphindiwe ukuze kuzuzwe inhloso yokuxhumanisa imvamisa yemishini kanye nemishini.Kuleli phepha, indlela yesici esilinganiselwe inganquma imvamisa lapho uklama umhlangano.Iphutha phakathi kwemiphumela yokuhlola yezinto ezisetshenziswayo kanye nemvamisa yokuklama ingaphansi kuka-1%.Ngasikhathi sinye, leli phepha lethula umqondo we-DFSS (Design For Six Sigma) ukuze ulungiselele futhi Udizayine amathuluzi ngokuqinile.Umqondo womklamo we-6-Sigma uwukuqoqa ngokugcwele izwi lamakhasimende ohlelweni lokuklama ukwenza umklamo ohlosiwe;Ukwengeza, ukuchezuka okungenzeka kwenqubo yokukhiqiza kufanele kucatshangelwe kusenesikhathi ukuze kuqinisekiswe ukuthi ikhwalithi yomkhiqizo wokugcina isatshalaliswa ngezinga elifanelekile.
