Uxhumano lwebhawodi lwamandla aphezulu ludlula induku enkulu yokuqinisa ibholithi yokuzenzisa ngaphakathi kwepuleti lokuxhuma ipuleti lokunamathisela ucezu, okwanele ukukhiqiza ukungqubuzana okuningi, ukuze kuthuthukiswe ubuqotho nokuqina kokuxhumana, lapho ukugunda, ngokuhambisana nezidingo ukuklama nokucindezeleka kuhlukile, kungahlukaniswa ngohlobo lokungqubuzana kokuxhumeka kwebhawudi yamandla aphezulu namandla aphezulu okuxhumanisa uhlobo lwengcindezi emibili, umehluko obalulekile phakathi kwezimo ezimbili zomkhawulo uhlukile, nakuba kuwuhlobo olufanayo lwebhawodi, kodwa ukubala indlela, izidingo, ububanzi bokufaka isicelo kuhluke kakhulu.Ekuklanyweni kwe-shear, uxhumano lwe-braction friction ye-bolt yamandla aphezulu ibhekisela kumandla amakhulu okungqubuzana okungenzeka ahlinzekwe ngamandla okuqinisa ibhawodi phakathi kwamandla angaphandle okugunda kanye nendawo yokuxhumana yepuleti njengomkhawulo. isimo, okungukuthi, ukuqinisekisa ukuthi amandla okugunda kwangaphakathi nangaphandle kokuxhuma awedluli amandla amakhulu okungqubuzana phakathi nayo yonke isevisi.isikhathi.Ngeke kube khona ukuguqulwa kwesiliphu esihlobene sepuleti (ikhala langempela phakathi kwesikulufu nodonga lwembobo lihlala ligcinwe).Ekuklanyweni kokugunda, uhlobo lokucindezela okuxhunywa kwebhawodi lamandla aphezulu luvunyelwe kumandla ogunda angaphandle adlula amandla amakhulu okungqubuzana. , isihlobo esishelelayo phakathi kokuwohloka kwepuleti elixhunyiwe, kuze kube yilapho kuthintana nebhawodi nodonga lwembobo, bese kuxhunywa ku-shear ye-shaft ye-bolt kanye nokucindezela odongeni lwembobo kanye nokungqubuzana phakathi kwamandla ahlangene wephaneli elingaphezulu kokuxhumana, ekugcineni kushear ku-shaft noma ukucindezela ukonakala kodonga lwembobo njengoba kwamukele ngisho nesimo somkhawulo wokugunda.Ngamafuphi, uhlobo lokungqubuzana amabhawodi anamandla amakhulu kanye nohlobo oluthwala ukucindezela amabhawodi anamandla aphezulu awuhlobo olufanayo lwamabhawodi, kodwa umklamo
Ukushelela akucatshangwa.Ibhawodi enamandla amakhulu ohlobo lwefriction ayikwazi ukushelela, ibhawodi alinawo amandla okugunda, uma ushelele, umklamo uthathwa njengofinyelela esimweni sokwehluleka, uvuthiwe kubuchwepheshe; nemishudo inamandla okugunda.Umonakalo wokugcina ulingana nalowo wamabhawudi ajwayelekile (i-shear yebhawodi noma i-steel plate crushing). Ngokombono wokusetshenziswa:
Ukuxhunywa kwebhawodi kwelungu eliyinhloko lesakhiwo sesakhiwo ngokuvamile kwenziwa ngebholidi enamandla kakhulu.Amabholithi avamile angasetshenziswa kabusha, amabhawodi anamandla amakhulu awakwazi ukuphinda asetshenziswe.Amabhawodi anamandla aphezulu asetshenziswa ngokuvamile ukuze kuxhunywe unomphela.
Ama-bolts anamandla aphezulu ama-bolts ane-prestressed, uhlobo lwe-friction ne-torque wrench ukuze kusetshenziswe i-prestress enqunyiwe, uhlobo lokucindezela olususa ikhanda le-plum.Ama-bolts avamile anokusebenza okungalungile kwe-shear futhi angasetshenziswa ezingxenyeni zesakhiwo sesibili.Amabhawodi ajwayelekile adinga ukuqiniswa kuphela.
Amabhawodi ajwayelekile ngokuvamile ayikilasi 4.4, ikilasi 4.8, ikilasi 5.6 kanye nekilasi 8.8.Amabhawodi anamandla aphezulu ngokuvamile angu-8.8 no-10.9, angu-10.9 iningi lawo.
8.8 yizinga elifanayo nelithi 8.8S.Izakhiwo zemishini kanye nezindlela zokubala zebhawodi ezejwayelekile kanye nebhawodi lamandla aphezulu zihlukile.Ingcindezi yebhawodi enamandla kakhulu okokuqala ngqa ngokusebenzisa i-pretension P ngaphakathi kwayo, bese kuba ukumelana nokungqubuzana phakathi kwendawo yokuxhumana yesiqeshana sokuxhuma ukuthwala umthwalo wangaphandle, futhi umshudo ojwayelekile uthwala ngqo umthwalo wangaphandle.
Ukuxhumeka kwebholithi yamandla aphezulu kunezinzuzo zokwakha okulula, ukusebenza kahle kwemishini, okungenakugwemeka, ukumelana nokukhathala, nangaphansi kwesenzo somthwalo oguquguqukayo, okuyindlela yokuxhumana ethembisa kakhulu.
Ibhawodi lamandla aphezulu ukusebenzisa isikrufu esikhethekile ukuqinisa inati, ukuze ibhawudi likhiqize ukuzenzisa okukhulu nokulawulwayo, ngokusebenzisa i-nati nepuleti, ukuze lixhunywe inani elifanayo lokucindezela kwangaphambili.Ngaphansi kwesenzo se-pre-pressure. , amandla amakhulu okungqubuzana azokwenziwa endaweni yocezu oluxhunyiwe.Ngokusobala, inqobo nje uma amandla e-axial engaphansi kwalokhu kuqhuma kwamandla, ilungu ngeke lishelele futhi ukuxhumana ngeke konakale.Lesi yisimiso sokuxhuma kwebhawodi lamandla aphezulu.
Uxhumano lwebhawodi lamandla amakhulu luncike emandleni okungqubuzana phakathi kwezindawo zokuthintana zezingxenye ezixhumayo ukuze kuvinjelwe ukushelela okufanayo.Ukuze ube namandla anele okushayisana ezindaweni ezithintana naye, kuyadingeka ukwandisa amandla okubamba kanye ne-coefficient yokungqubuzana kwezindawo zokuthintana zamalungu.Amandla okubamba phakathi kwamalungu atholwa ngokusebenzisa ukuzenzisa kumabhawodi, ngakho-ke amabhawodi kufanele zenziwe ngensimbi enamandla amakhulu, yingakho zibizwa ngokuthi izixhumanisi zamabhawodi aphezulu.
Ekuxhumekeni kwebhawodi lamandla amakhulu, i-coefficient yokungqubuzana inethonya elikhulu kumthamo wokuthwala.Ukuhlola kubonisa ukuthi i-coefficient yokushayisana ithintwa ikakhulukazi uhlobo lwendawo yokuthintana nezinto ze-component.Ukuze kwandiswe i-coefficient yokungqubuzana kwendawo yokuthintana. , izindlela ezifana nokuqhunyiswa kwesihlabathi nokuhlanza ibhulashi lezintambo zivame ukusetshenziswa ekwakhiweni ukuze kuphathwe indawo yokuxhumana yezingxenye ngaphakathi kwebanga lokuxhuma.
