Insimbi enamandla amakhuluingasetshenziswa ezakhiweni zensimbi ukuze kugcinwe inani lensimbi esetshenzisiwe futhi kuncishiswe izindleko zokwenziwa kwesakhiwo sensimbi, ukuthutha nokufakwa.Njengoba izakhiwo zemishini yensimbi enamandla amakhulu zinomehluko ongenakuqhathaniswa nensimbi evamile, izazi zasekhaya nakwamanye amazwe zenze umsebenzi omningi wokucwaninga ngokusetshenziswa kwensimbi yesakhiwo esinamandla amakhulu eminyakeni yamuva.

Ngaphezu kokuklama kwamalungu okunengqondo, izakhiwo zensimbi ezinamandla aphezulu zidinga ukuxhumana okuphumelelayo phakathi kwamalungu ensimbi anamandla amakhulu ukuze enze isakhiwo esiphephile nesithembekile.

Inqubekelaphambili yocwaningo yezindlela ezimbili ezibalulekile zokuxhuma insimbi enamandla amakhulu (i-welding kanye ne-bolting) ekhaya nakwamanye amazwe iyethulwa, okuhlanganisa: ucwaningo mayelana nokusebenza okuthwala umthwalo wokuxhumeka kwensimbi enamandla kakhulu ye-butt-weld, ucwaningo mayelana nokuthwala umthwalo. ukusebenza koxhumo lwensimbi olunamandla aphezulu lwe-fillet-weld, ucwaningo ekusebenzeni okuthwala umthwalo we-bolting yohlobo lwensimbi oluqinile oluqinile, ucwaningo ngokusebenza okuthwala umthwalo we-bolting yohlobo lokucindezelwa kwensimbi ephezulu kanye nocwaningo nge-hydrogen- ukubambezeleka kokuphuka kwamabhawodi aqine kakhulu ebangeni le-12.9, njll., futhi kugqamisa inqubekelaphambili yocwaningo lweNyuvesi yaseTongji.I-Tongji University, ifinyeza inqubekelaphambili yocwaningo olukhona kanye nokubheka phambili ocwaningweni oluzayo.

Ukusetshenziswa kokulinganisa okungaphansi kwamandla ku-butt welding yensimbi enamandla amakhulu kunganciphisa izinga lokushisa lokushisa kwe-welding, kunciphise ukukhubazeka kwe-welding futhi kuthuthukise i-ductility ye-joint.

Kodwa-ke, ukufanisa okungaphansi kwamandla kungaba nomthelela obalulekile kumthamo wokuthwala umthwalo wejoyinti elishiselwe.Abacwaningi abaningi babonise ukuthi imiphumela yekhodi yaseYurophu engu-EC3 ekufanisweni okungaphansi kwamandla amalungiselelo okubala amandla wamalunga ashiselwe inengqondo noma iyalondoloza.

Isenzo sokuthambisa insimbi enamandla aphezulu ngemva kokushisela kanye nosayizi wezinga lokuthambisa kanye nendlela yokuqinisa insimbi, inqubo yokugingqika nokuzwela ekwelapheni ukushisa, ngenxa yensimbi enamandla kakhulu enqubweni yokugingqa kube ukwelashwa okukodwa noma ngaphezulu kokushisa, insimbi eseduze. i-weld kanye nokokufaka ukushisa kanye nokupholisa umjikelezo wokushisa umjikelezo, ukuze ingakwazi ukugcina izakhiwo zangempela zemishini, futhi ngenxa yalokho indawo ethinteke ukushisa.

Izici ezithize ezithinta amandla ejoyinti elishiselwe zihlanganisa amandla ento eshiselwe, ububanzi bendawo yokushisela, amandla wendawo othambisayo, ububanzi bendawo ethambile, isilinganiso sobubanzi nobukhulu bengxenye eshiselwe kanye ne-engeli ye-weld bevel.

I-1) izindlela ezahlukene zokuthatha umthwalo we-slip zinomthelela omkhulu ku-coefficient ephikisana nokushelela, futhi inani le-anti-slip coefficient yekhodi yaseShayina liyi-7% kuya ku-20% enkulu kunenani lekhodi yaseYurophu.

2) Endaweni eqhumayo, inani elilinganisiwe le-anti-slip coefficient yensimbi enamandla amakhulu liphakathi kuka-0.45 no-0.50 ngokuvumelana nekhodi yaseYurophu, futhi uma kucatshangelwa izinga elithile lesiqinisekiso sokuphepha, inani elihambisanayo lomklamo liphakathi 0.4 kanye no-0.45.

3) TI-coefficient emelene nokushelela yendawo ebomvu yokugqwala ngemva kokudubula ukuqhuma kwensimbi enamandla ngokuvamile kukhulu kunaleyo yendawo eqhumayo.

4) Tyena anti-slip coefficient ofphezulu tensilesintambo yobudeindawo yokuxubha ngokwezinkambiso zaseYurophu iseduze nenani elithathwe ngokwemithetho yamaShayina, i-anti-slip coefficient iyancipha ngokukhula kwebanga lamandla ensimbi.

5) Ukwelashwa okungaphezulu kwensimbi enamandla kakhulu eqhunyiswe futhi kuhlanganiswe ngopende ocebile nge-zinc kungakhuphula ukuzinza kwe-coefficient emelene nokushelela kwendawo yokungqubuzana, futhi izinga le-anti-slip coefficient livamise ukuba lincane kunezinye indawo. izindlela zokwelapha.Ugqinsi lukapende olunothe nge-zinc lwe-inorganic lusiza ekuthuthukisweni kwe-coefficient yokumelana nokushelela, futhi i-coefficient yokumelana nokushelela ye-coefficient ewugqinsi icishe ibe ngu-10% ephakeme kunaleyo ye-coefficient encane.
