Iziteshi zensimbiziyisici esibalulekile sezimboni zokwakha nezokukhiqiza, ezaziwa ngokuguquguquka kwazo namandla azo. Njengoba zibunjwe njengo-“C” noma “U,” lezi zakhi zesakhiwo zisetshenziswa ezinhlotsheni ezahlukene zokusebenza kusukela ozimele bokwakha kuya ekusekeleni imishayo. Ukuqonda amandla eziteshi zensimbi kubalulekile konjiniyela, abakhi bezakhiwo, kanye nabakhi lapho beklama izakhiwo ezidinga ukuqina nokuzinza.
Amandla e-isiteshi sensimbikunqunywa yizici eziningana, okuhlanganisa izakhiwo zayo zezinto, ubukhulu, kanye nemithwalo ethile eyenzelwe ukumelana nayo. Insimbi, njengezinto ezibonakalayo, yaziwa ngamandla ayo aphezulu okuthambekela, okuvumela ukuthi imelane namandla amakhulu ngaphandle kokuguquka. Amandla okukhiqiza ensimbi yesakhiwo ngokuvamile aphakathi kuka-250 MPa no-350 MPa, kuye ngokuthi insimbi isetshenziswa kangakanani. Lokhu kusho ukuthi isiteshi sensimbi singasekela imithwalo esindayo ngenkathi sigcina ubuqotho besakhiwo saso.
Ubukhulu besiteshi sensimbi budlala indima ebalulekile emandleni aso. Iziteshi ziza ngobukhulu obuhlukahlukene, ngobubanzi beflange obuhlukahlukene, ukuphakama nobukhulu. Isikhathi se-inertia siyisilinganiso sokumelana nento ekugobeni futhi siyisici esibalulekile ekunqumeni ukuthi isiteshi singamelana nomthwalo ongakanani. Lapho isikhathi se-inertia sikhulu, isiteshi siqina kakhulu nokuthi singamelana kahle kangakanani nokugoba ngaphansi komthwalo. Onjiniyela bavame ukubhekisela kumathebula ajwayelekile anikeza izakhiwo zobukhulu obuhlukene besiteshi sensimbi, okubavumela ukuthi bakhethe isiteshi esifanele sohlelo oluthile.
Umthamo wokuthwala umthwalo we-isiteshi sensimbiithintwa ukuqondiswa kwayo kanye nohlobo lomthwalo ebhekene nawo. Uma isiteshi siqondiswe phezulu, singasekela ngempumelelo imithwalo ye-axial, kuyilapho ukuqondiswa okuvundlile kufaneleka kangcono ekumelaneni nezikhathi zokugoba. Ngaphezu kwalokho, uhlobo lomthwalo, kungaba oqhubekayo (oqhubekayo) noma oguquguqukayo (oshintshayo), luzothinta nokusebenza kwesiteshi. Isibonelo, isiteshi sensimbi esisetshenziswa ebhulohweni kumele sakhiwe ukuze simelane nemithwalo yezimoto eguquguqukayo, kanti isiteshi esisetshenziswa ohlakeni lwesakhiwo singasekela kakhulu imithwalo ye-static.
Iziteshi zensimbi zisetshenziswa ezinhlobonhlobo zezicelo ngenxa yamandla azo kanye nokuguquguquka kwazo. Ekwakhiweni, zisetshenziswa njengemishayo, amakholomu, kanye nama-bracket ukunikeza ukwesekwa okudingekayo kwezakhiwo. Ekwenzeni, zivame ukusetshenziswa ukudala imishini nemishini. Zishintshwa kalula, ziboshwe ngebhawodi, noma ziboshwe nge-riveting, okwenza zibe ukukhetha okuphezulu kumaphrojekthi amaningi.
Nakuba ziqinile, iziteshi zensimbi nazo zingase zigqwale, okungenza buthaka ubuqotho bazo besakhiwo ngokuhamba kwesikhathi. Ukuze kulwiwe nalokhu, iziteshi eziningi zensimbi ziphathwa ngesembozo esivikelayo noma zenziwe ngensimbi eqinisiwe, okwandisa ukumelana kwazo nokugqwala futhi kwandise isikhathi sazo sokusebenza. Ukugcinwa nokuhlolwa njalo kubalulekile ukuqinisekisa ukuthi iziteshi zensimbi zihlala ziqinile futhi zisebenza kahle kuyo yonke impilo yazo yokusebenza.
Ngokufigqiwe,iziteshi zensimbiziyisici esiqinile kakhulu sesakhiwo esidlala indima ebalulekile ezimbonini ezahlukahlukene. Amandla azo athintwa yizakhiwo zezinto ezibonakalayo, ubukhulu, kanye nezimo zokulayisha. Ngokuqonda lezi zici, onjiniyela nabakhi bangasebenzisa ngempumelelo iziteshi zensimbi ukudala izakhiwo eziphephile neziqinile. Kungakhathaliseki ukuthi kusekukhiqizweni, ekukhiqizeni, noma kwezinye izinhlelo zokusebenza, amandla eziteshi zensimbi azenza zibe yingxenye ebalulekile yobunjiniyela besimanje.
→Ukuze uthole yonke imikhiqizo, izinsizakalo kanye nolwazi olusesikhathini, sicelaXhumana nathi.
