Tube e sekwere VS tube e khutlonnetsepa, ke sebopeho sefe se tšoarellang haholoanyane?
Phapang ea ts'ebetso lipakeng tsaphaephe e khutlonnetsepalephaephe e sekwerelits'ebetsong tsa boenjiniere li hloka ho hlahlojoa ka botlalo ho tsoa maikutlong a mangata a mechini joalo ka matla, ho tiea, botsitso le bokhoni ba ho jara.
1. Matla (ho kobeha le ho hanyetsa ho torsion)
Matla a ho kobeha:
Tube e khutlonnetsepa: Ha e kobeha ka lehlakoreng le lelelele (lehlakore la bophahamo), motsotso wa ho se inertia wa karolo o moholo, mme khanyetso ya ho kobeha e betere haholo ho feta ya tube e kgutlotharo.
Mohlala, matla a ho kobeha a phaephe e khutlonnetsepa ya 100×50mm ka lehlakoreng le lelelele a phahame ho feta a phaephe e kgutlonnetsepa ya 75×75mm.
Tube e sekwere: Nako ea inertia e tšoana ka mahlakoreng 'ohle, 'me ts'ebetso ea ho kobeha e lekana, empa boleng ba eona hangata bo bonyenyane ho feta ba tataiso e telele ea lehlakore la tube e khutlonnetsepa tlas'a sebaka se le seng sa karolo e tšekaletseng.
Qeto: Haeba tataiso ea mojaro e hlakile (joalo ka sebopeho sa mahlasedi), phaephe e khutlonnetsepa e betere; haeba tataiso ea mojaro e fetoha, phaephe e sekoere e leka-lekane haholoanyane.
Matla a ho kgutla ha mmele:
Phetoho e sa fetoheng ea tube ea sekwere e phahame, kabo ea khatello ea torsion e tšoana haholoanyane, 'me khanyetso ea torsion e betere ho feta ea tube e khutlonnetsepa. Mohlala, khanyetso ea torsion ea tube ea sekwere ea 75×75mm e matla haholo ho feta ea tube e khutlonnetsepa ea 100×50mm.
Qeto: Ha mojaro oa torsional o le matla (joalo ka moqomo oa phetisetso), lipeipi tse sekwere li betere.
2. Ho satalla (bokhoni ba ho thibela ho fetoha ha sebopeho)
Ho thatafala ha ho kobeha:
Ho satalla ho lekana le motsotso oa ho se be le nako. Liphaephe tse khutšoane li na le ho satalla ho hoholo lehlakoreng le lelelele, e leng se loketseng maemo a hlokang ho hanela ho kheloha ka lehlakoreng le le leng (joalo ka maballo a borokho).
Li-tube tse sekwere li na le ho tiea ha mahlakoreng a mabeli ka mokhoa o lekanang 'me li loketse meroalo e mengata (joalo ka likholomo).
Qeto: Litlhoko tsa ho satalla li ipapisitse le tataiso ea mojaro. Khetha lipeipi tse khutlonnetsepa bakeng sa mojaro o le mong; khetha lipeipi tse sekwere bakeng sa mojaro o le mong.
3. Botsitso (ho hanyetsa ho thekesela)
Ho thiba ha lehae:
Hangata lipeipi tse khutlonnetsepa li na le karolelano e kholoanyane ea bophara le botenya, 'me likarolo tse nang le mabota a masesaane li sekamela haholoanyane ho kobeha ha sebaka, haholo-holo tlas'a khatello kapa moroalo oa ho kuta.
Lipeipi tse sekwere li na le botsitso bo betere ba sebaka ka lebaka la ho ba le karolo e lekanang.
Ho thiba ka kakaretso (ho thiba ka Euler):
Moroalo oa ho khomarela o amana le radius e nyane ea ho khomarela karolo e tšekaletseng. Radius ea ho khomarela lipeipi tse sekwere e tšoana ka mahlakoreng 'ohle, ha radius ea ho khomarela lipeipi tse khutlonnetsepa ka lehlakoreng le lekhutšoanyane e le nyane, e leng se etsang hore li be kotsing ea ho khomarela.
Qeto: Li-tube tse sekwere li khethoa bakeng sa litho tse hatellang (tse kang lipilara); haeba tataiso e telele ea lehlakore la tube e khutlonnetsepa e lekanyelitsoe, e ka buseletsoa ka moralo.
4. Bokgoni ba ho jara (meroalo e axial le e kopaneng)
Khatello ea Axial:
Bokgoni ba ho bea bo amana le sebaka se tshekaletseng le karolelano ya bosesane. Tlas'a sebaka se le seng se tshekaletseng, diphaephe tse sekwere di na le bokgoni bo phahameng ba ho bea ka lebaka la radius ya tsona e kgolo ya ho reteleha.
Moroalo o kopaneng (khatello e kopaneng le ho kobeha):
Lipeipi tse khutlonnetsepa li ka sebelisa monyetla oa sebopeho se ntlafalitsoeng ha tataiso ea motsotso oa ho kobeha e hlakile (joalo ka mojaro o otlolohileng ka lehlakoreng le lelelele); lipeipi tse sekwere li loketse linako tsa ho kobeha tse peli.
5. Mabaka a mang
Tšebeliso ea thepa:
Lipeipi tse khutlonnetsepa li sebetsa hantle haholo 'me li boloka thepa ha li kobeha ka lehlakoreng le le leng; lipeipi tse sekwere li theko e tlaase haholo tlas'a meroalo e mengata.
Bonolo ba khokahano:
Ka lebaka la ho lekana ha lipeipi tse sekwere, likhokahano tsa li-node (tse kang ho tjheseletsa le li-bolt) li bonolo; lipeipi tse khutlonnetsepa li hloka ho nahana ka tataiso.
Maemo a tshebediso:
Liphaephe tse khutlonnetsepa: maballo a moaho, matsoho a crane, khese ea koloi (tataiso e hlakileng ea mojaro).
Liphaephe tse sekwere: litšiea tsa moaho, li-trus tsa sebaka, liforeimi tsa mechini (meroalo e nang le mahlakore a mangata).
