Imibuzo emi-5 yobuNjineli beNsimbi eqhelekileyo kunye neempendulo zobuGcisa

Uyilo, ukwenziwa kunye nokwakhiwa kwendawoubunjineli besakhiwo sentsimbikubandakanya iikhonsepthi ezininzi zoomatshini, iiparamitha zecandelo kunye nokuhlelwa kolwakhiwo. Ngexesha lomzobo wemihla ngemihla, ukujonga umthwalo kunye nothelekiso lwesikimu, uninzi lweengcali zihlala zinentandabuzo malunga nemigangatho eyahlukeneyo yobugcisa, iziphumo zoomatshini kunye neendlela zokukhetha zamalungu olwakhiwo. Ukunceda amagcisa angaphambili kunye nabalungelelanisi borhwebo lwangaphandle ngokukhawuleza ukulungisa iithiyori ezingundoqo kunye nokuphepha iimpazamo zoyilo, olu xwebhu luqulunqa imibuzo ebuzwa rhoqo malunga nezakhiwo zentsimbi kunye neempendulo ezimfutshane.

Q1. Yintoni i-diaphragm effect?

Isiphumo se-diaphragm sibhekisa kukuziphatha komatshini apho iipaneli ezivalelekileyo zixhathisa ukuguqulwa kwe-in-plane okubangelwa yimithwalo engaphakathi kwinqwelomoya ngenxa yokuqina kwe-chear. Ukuqina kunye namandla amacandelo zizibonakaliso ezimbini eziphambili zokuvavanya ukusebenza kwayo.

Q2. Ngaba i-shear lag kunye ne-shear lag isiphumo ingcamango efanayo?

Babhekisa kwinto efanayo yomatshini; "i-shear lag" lelinye igama le-shear lag effect, enokuchazwa ngumgaqo kaSaint-Venant. Ngexesha lokugqithiselwa komthwalo ngaphakathi kwelungu, ukulibaziseka kokuhanjiswa kwamandla okucheba kwimimandla yendawo kukhokelela ekusasazweni okungalinganiyo koxinzelelo oluqhelekileyo phezu kwecandelo elinqamlezayo, kwaye le nto idibeneyo ibizwa ngokuba yi-shear lag.

Q3. Ziziphi iziphumo eziya kuzisa ukuphambuka okugqithisileyo kwezakhiwo zentsimbi?

Ukuba uphambuko lwe-aisakhiwo sentsimbiidlula umda ochazwe ngeekhowudi, ukuguqulwa okubonakalayo kwamacandelo kuya kwenzeka kwaye konakalise inkangeleko yoyilo. Ngeli xesha, ukusebenza kwenkonzo yesakhiwo kuya konakala, kwaye ukuphambuka okugqithisileyo kwexesha elide kuya kudala iingozi ezinokubakho kukhuseleko lwesakhiwo.

Q4. Indlela yokwahlula iintonga eziqinileyo zokubopha kwiintsimbi eziguquguqukayo zokubopha?

Iinduku zokubopha eziqinileyo zinokuthwala zombini ukuxinana kunye noxinzelelo, kwaye zihlala zithatha intsimbi ephindwe kabini yentsimbi okanye amacandelo anqamlezayo etyhubhu yentsimbi. Iintonga zokubopha eziguquguqukayo zinokuxhathisa kuphela uxinzelelo ngaphandle komthamo ocinezelayo, owenziwe ngokubanzi ngentsimbi enye okanye iityhubhu ezingqukuva.

Q5. Kuthetha ukuthini ukuthwala umthamo wasemva kwe-buckling?

Umthamo wokuthwala i-post-buckling ubhekisele ngokukodwa kwintsalela yomthamo wokuthwala wamalungu anodonga olucekethekileyo emva kokwenzeka kwe-buckling yendawo. Esi salathiso sinqunywe ngokudibeneyo ngumlinganiselo wobubanzi bobunzima beepleyiti kunye neemeko zokunqanda umgca: umlinganiselo omkhulu wobubanzi kunye nezithintelo zomda ezinamandla ziya kubangela umthamo ophezulu wokuthwala i-post-buckling residual yelungu.

Ukuqukumbela

Iithiyori ezibandakanyekayo kuyilo, ukuveliswa kunye nokwakhiwa kwezakhiwo zetsimbi zibanzi kwaye zihambelana, kwaye i-Q & A engentla igubungela kuphela iqhekeza elincinci lemiba eqhelekileyo.Ubunjineli besakhiwo sentsimbiluqeqesho oludibanisa ulwazi lwethiyori namava okwenziwa komsebenzi. Ukuqonda la manqaku angundoqo kufuna okungaphezulu kunokunkqaya iinkcazelo zamagama; uthelekiso oluphindaphindiweyo, ukucamngca kunye nokuqinisekiswa kwiinkqubo zeprojekthi zokwenyani ziyimfuneko. Kuyathenjwa ukuba olu xwebhu lwe-Q&A lunokubonelela abafundi ngesiqalo esicacileyo, esibavumela ukuba bafumane ngokukhawuleza iireferensi ezifanelekileyo kunye nezisombululo xa behlangabezana neengxaki zobunjineli ezisebenzayo.
