Izakhiwo ze-truss zimele incopho yokusebenza kakuhle kwesakhiwo kubunjineli banamhlanje. Ngokuhlela iiyunithi ezizinxantathu, izakhiwo ze-truss zisasaza imithwalo kumalungu adibeneyo, ziqinisekisa uzinzo ngokusetyenziswa okuncinci kwezinto.
Namhlanje, ii-truss zixhasa yonke into ukusuka kuphahla olukhulu lwenkundla ukuya kwiziseko zebhulorho ezibalulekileyo. Ubulula bazo bejometri bufihla ingqiqo enobuchule yoomatshini ephucukileyo ekhulisa umlinganiselo wamandla nobunzima. Njengoko iindawo zasezidolophini zisiba nzima ngakumbi, ukuxhomekeka kwiinkqubo ze-truss ezisebenza kakuhle kuyakhula.
Iindlela zozinzo zolwakhiwo lweTruss: Ijiyometri kunye noSasazo loMthwalo
Umgaqo osisiseko we-truss ulele kunxantathu. Ngokungafaniyo ne-polygon enamacala amane, unxantathu awunakutshintsha imo ngaphandle kokutshintsha ubude bamacala awo. Oku kuqina kwejometri kuvumela ii-truss ukuba zimelane nokuguquguquka ngempumelelo. Kwi-truss eqhelekileyo, amalungu afumana uxinzelelo okanye ukucinezelwa.
Umzekelo, kwi-Pratt truss elula, amalungu athe nkqo aphatha ukucinezelwa ngelixa amalungu axwesileyo elawula ukuxinezeleka. Iinjineli zisebenzisa iNdlela yeeJoints ukubala amandla angaphakathi kuyo yonke indawo edibana kuyo.
Kwimeko ezilungileyo zoyilo, i-i-truss yentsimbiinokuxhasa ubunzima bayo ngokuphindwe kaninzi. Oku kusebenza kakuhle kuvela kwinto yokuba ii-truss zinciphisa kakhulu amaxesha okugoba, zivumela amalungu ukuba athwale ikakhulu amandla e-axial. Endaweni yoko zigxila kumandla e-axial. Olu gxininiso luvumela amacandelo amancinci kunye neendleko eziphantsi.
Uninzi lwee-truss zemizi-mveliso zisebenzisa intsimbi enamandla kakhulu ene-modulus yokuthamba ejikeleze i-200 GPa. Olu kuqina luphezulu luqinisekisa ukuba isakhiwo sigcina imo yaso phantsi kwemithwalo enzima yokusingqongileyo. Abayili badla ngokusebenzisa imodeli yekhompyutha ukulinganisa iindawo zoxinzelelo ngaphambi kokuba kuqalwe ukwenziwa. Oku kuchaneka kunciphisa inkunkuma yezinto ezibonakalayo phantse nge-15% xa kuthelekiswa nokwakhiwa kwemiqadi yendabuko. Ngokugxila ekuthwaleni imiqadi, iinjineli zifikelela kwiindawo ebezingenakwenzeka ngemiqadi eqinileyo.
Ukugqwesa kwezinto zokwakha iTruss: Intsimbi vs. iAluminiyam
Ukukhetha izinto ezisetyenzisiweyo kumisela ukusebenza kunye nobude bexesha le-truss. Intsimbi ihlala ilukhetho oluphambili kwiindlela ezinzima zokusebenza. Intsimbi yeGrade S355, esetyenziswa rhoqo kwiiprojekthi zamazwe ngamazwe, inika amandla okuvelisa angama-355 MPa. Ukuqina kwayo kuyenza ilungele iibhulorho kunye nee-reinforcements eziphakamileyo. Ngokwahlukileyo koko, ii-truss ze-aluminium ziyanda kwimveliso yeziganeko kunye nezakhiwo zexeshana.
I-Aluminium 6082-T6 inika amandla okuvelisa amalunga ne-250 MPa kodwa inobunzima obungaphantsi ngama-66% kunentsimbi. Izibalo zibonisa ukuba ukusebenzisa i-aluminium kunokunciphisa iindleko zokuthutha ngama-40% kwiindawo zokubeka izinto. Ngelixa intsimbi inika ukumelana nomlilo okuphezulu kunye nokuqina ixesha elide, i-aluminium inika ukuthwaleka okungenakuthelekiswa nanto.
Ukumelana nokugqwala nako kwahluka phakathi kwezi zinyithi. Intsimbi egayiweyo imelana nokugqwala amashumi eminyaka, nakwiindawo ezikufutshane nolwandle. Nangona kunjalo, i-aluminium ngokwemvelo yenza umaleko we-oxide okhuselayo. Olu maleko luthintela ukuwohloka okunzulu kwesakhiwo ngaphandle kokugqunywa okongeziweyo. Abenzi bezinto zanamhlanje badla ngokusebenzisa i-powder coating ukuphucula ubuhle kunye nokhuseleko.
Kwimarike yangoku, ii-trus zentsimbi zimalunga nama-70% kwicandelo lemizi-mveliso. I-aluminium ilawula indawo yokuzonwabisa neyokubonisa ngenxa yokuba kulula ukuyihlanganisa. Ukukhetha izinto ezifanelekileyo kubandakanya ukulinganisela iindleko zokuqala, iimfuno zobunzima, kunye nobomi obulindelekileyo beprojekthi.
Utshintsho kwiSakhiwo: Ukusuka kwiWarren ukuya kwiSpace Frames
Iinjineli zikhetha iintlobo ze-truss ngokusekelwe kwiimfuno ze-span kunye neenjongo zobuhle. I-Warren truss, ebonakaliswa ziinxantathu ezilinganayo, inciphisa ubude bebonke bamalungu. Isebenza kakuhle kakhulu kwi-span ephakathi kweemitha ezingama-20 kunye ne-100. Kwiindawo ezinkulu nangakumbi, njengee-terminals zesikhululo seenqwelo-moya, abayili basebenzisa izakhelo zesithuba. Ezi truss ze-3D zisasaza imithwalo ngobukhulu obuthathu endaweni yeplane enye.
Uphando lubonisa ukuba izakhelo zesithuba zifikelela kumgama ongaphezulu kweemitha ezili-150 kwiiprojekthi ezinkulu ezikhethekileyo. Olu buchule ludala ingaphakathi elikhulu nelivulekileyo leehangari kunye neendawo zendibano. Kubunjineli bebhulorho, i-Howe truss isebenzisa amalungu athe nkqo ekucinezeleni, okuhambelana noyilo oluthile olunzima lwemithi. Isoftware yanamhlanje ngoku ivumela uyilo lokuvelisa. Le nkqubo idala iipateni ze-truss ezilungiselelweyo ezisebenzisa izinto ezingaphantsi ngama-20% kunezo zemveli. Ezi zixhobo zedijithali ziqinisekisa ukuba yonke igram yentsimbi inegalelo kwisakhiwo esisemgangathweni.
Ngaphezu koko, ii-truss ezikhethekileyo ezifana ne-Fink truss zibonelela ngenkxaso egqwesileyo kwiindawo zokuhlala zophahla. Uhlobo ngalunye lujongana nomngeni othile woomatshini. I-Warren truss inciphisa iindawo zokuwelda, nto leyo enciphisa iindleko zomsebenzi wokuvelisa nge-10%. Okwangoku, i-K-truss inceda ekuthinteleni ukugoba kwiindlela zoyilo lweebhulorho ezinde kakhulu. Ukwahluka kweentlobo ze-truss kuqinisekisa isisombululo sayo yonke imbono yoyilo.
Impembelelo yoQoqosho kunye noFakelo lweZakhiwo zeTruss
Ixabiso lezoqoqosho lee-trusses lidlula ukonga izinto eziphathekayo. Ngenxa yokuba izinto ezisetyenzisiweyo zilungiswa kwiifektri, umsebenzi owenziwa kwindawo uyancipha kakhulu. Izifundo zibonisa ukuba uphahla olusekelwe kwi-truss lufakwa ngokukhawuleza ngama-30% kuneenkqubo zemveli ze-beam-and-column. Esi santya sinciphisa iindleko zemali kubaphuhlisi. Kwimarike yamazwe ngamazwe, ii-trusses ze-modular zivumela ukuthunyelwa okusebenzayo. Isikhongozeli esiqhelekileyo seenyawo ezingama-40 sinokubamba izinto zophahla lwendlu yokugcina impahla oluziimitha ezingama-500 ukuba senzelwe ukwakha iindlwane.
Ngaphezu koko, iindleko zokugcinwa kwee-trus zentsimbi eziqinisiweyo zihlala ziphantsi. Ubomi benkonzo buhlala budlula iminyaka engama-60 ngaphandle kokungenelela okuncinci. Imfuno yehlabathi yee-trus zentsimbi kufuneka ikhule nge-5.5% ngonyaka ukuya kutsho ngo-2030. Olu kukhula lulandela ukwanda kwemizi-mveliso kuqoqosho olusakhulayo. Ezi ndawo zifuna iindlela zokwakha ezikhawulezayo nezithembekileyo.
Ukongeza, ixabiso eliphezulu lentsimbi elahliweyo lenza ii-truss zibe lukhetho oluzinzileyo. Ekupheleni kobomi besakhiwo, abanini banokuphinda basebenzise phantse i-98% yesakhelo sentsimbi. Oku kujikelezisa kutsala abatyali-mali abagxile kwiinjongo zokusingqongileyo, ezentlalo, kunye nolawulo. Ukwenziwa ngaphandle kwendawo kukwaphucula ulawulo lomgangatho. Useto lwefektri luvumela uvavanyo lwe-ultrasonic lwe-welds, ukuqinisekisa izinga lempumelelo le-99.9% kwintsimi. Oku kuthembeka kunciphisa ukulibaziseka okubizayo kunye neengozi zokhuseleko ngexesha lesigaba sokwakha.
