Imibuzo emi-5 Evamile Yesakhiwo Sensimbi Nezimpendulo Zobuchwepheshe

Ukuklama, ukwakhiwa kanye nokwakhiwa endaweniubunjiniyela besakhiwo sensimbikubandakanya imiqondo eminingi yobungcweti bemishini, imingcele yezingxenye kanye nezigaba zesakhiwo. Phakathi nemininingwane yomdwebo wansuku zonke, ukuhlolwa komthwalo kanye nokuqhathanisa uhlelo, odokotela abaningi bavame ukuba nokungabaza ngamagama ahlukahlukene obuchwepheshe, imiphumela yemishini kanye nenqubo yokukhetha yamalungu esakhiwo. Ukuze usize ochwepheshe abaphambili nabaxhumanisi bezohwebo bangaphandle balungise ngokushesha amathiyori ayinhloko futhi bagweme amaphutha edizayini, lo mbhalo uhlanganisa imibuzo evame ukubuzwa yobungcweti mayelana nezakhiwo zensimbi nezimpendulo ezimfushane.

Q1. Uyini umphumela we-diaphragm?

Umthelela we-diaphragm ubhekisela ekuziphatheni kwemishini lapho amaphaneli ezivalekile amelana nokuguqulwa kwendiza okubangelwa imithwalo esendizeni ngenxa yokuqina kwawo kwe-shear. Ukuqina namandla ezingxenye yizinkomba ezimbili ezibalulekile zokuhlola ukusebenza kwayo.

Q2. Ingabe i-shear lag ne-shear lag effect ingumqondo ofanayo?

Babhekisela entweni efanayo yomshini; "i-shear lag" kumane kuyigama elihlukile lomphumela we-shear lag, ongachazwa ngomgomo kaSaint-Venant. Ngesikhathi sokudlulisa umthwalo ngaphakathi kwelungu, ukulibaziseka kokudluliselwa kwe-shear ezifundeni zendawo kuholela ekusabalaliseni okungalingani kwengcindezi evamile phezu kwesigaba esiphambanayo, futhi le nto ibizwa ngokuthi i-shear lag.

Q3. Imiphi imiphumela ezoletha ukuchezuka ngokweqile kwezakhiwo zensimbi?

Uma ukuchezuka kwangempela kwe-aisakhiwo sensimbiidlula umkhawulo oshiwo amakhodi, ukuwohloka okubonakalayo kwezingxenye kuzokwenzeka futhi konakalisa ukubukeka kwezakhiwo. Ngaleso sikhathi, ukusebenza kwesevisi yesakhiwo kuzokhinyabezeka, futhi ukuchezuka okweqile kwesikhathi eside kuzodala izingozi ezingaba khona zokuphepha kwesakhiwo.

Q4. Ungazihlukanisa kanjani izinti eziqinile zokubopha ezizindeni eziguquguqukayo zokubopha?

Izinti zikathayi eziqinile zingathwala kokubili ukungezwani nokuminyanisa, futhi ngokuvamile zisebenzisa insimbi ene-engeli ephindwe kabili noma iziphambano zeshubhu lensimbi eliyindilinga. Izinti zikathayi eziguquguqukayo zingamelana kuphela nokungezwani ngaphandle komthamo ocindezelayo, ngokuvamile owenziwe ngensimbi ye-engeli eyodwa noma amashubhu ayindilinga.

Q5. Kusho ukuthini umthamo wokuzala wangemuva kwebhande?

Umthamo wokuthwala i-post-buckling ubhekise ngqo kumthamo oyinsalela wokuthwala wezingxenye ezinezindonga ezincane ngemva kokwenzeka kwe-buckling yendawo. Le nkomba inqunywa ngokuhlanganyela isilinganiso sobubanzi bogqinsi bamapuleti nezimo zokuthibela unqenqema: isilinganiso esikhulu sobubanzi bokuqina kanye nemingcele eqinile evimbelayo kuzophumela ekuthwaleni okuphezulu kokuthwala insalela yelungu.

Isiphetho

Imibono ehilelekile ekwakhiweni, ekwenziweni nasekwakhiweni kwezakhiwo zensimbi ibanzi futhi ihlobene, futhi i-Q&A engenhla ihlanganisa kuphela ingxenye encane yezindaba ezivamile.Ubunjiniyela besakhiwo sensimbiisiyalo esihlanganisa ulwazi lwethiyori kanye nolwazi olusebenzayo. Ukwazi kahle la maphuzu abalulekile kudinga okungaphezu kokubamba izincazelo zamagama ngekhanda; ukuqhathanisa okuphindaphindiwe, ukucabangisisa kanye nokuqinisekiswa kwezinqubo zangempela zamaphrojekthi kubalulekile. Kwethenjwa ukuthi lo mbhalo we-Q&A unganikeza abafundi isiqalo esicacile, okubavumela ukuthi bathole ngokushesha izinkomba ezifanele nezisombululo lapho behlangabezana nezinkinga ezisebenzayo zobunjiniyela.
