Izakhiwo ze-truss zimelela isiqongo sokusebenza kahle kwesakhiwo kobunjiniyela besimanje. Ngokuhlela amayunithi angunxantathu, izakhiwo ze-truss zisabalalisa imithwalo kuwo wonke amalungu axhumene, okuqinisekisa ukuzinza ngokusetshenziswa okuncane kwezinto zokwakha.
Namuhla, ama-truss asekela yonke into kusukela ophahleni olukhulu lwenkundla kuya engqalasizinda yebhuloho elibalulekile. Ubulula bawo bejometri bufihla ingqondo eyinkimbinkimbi yemishini ekhulisa izilinganiso zamandla nesisindo. Njengoba izindawo zasemadolobheni ziba nzima kakhulu, ukuthembela ezinhlelweni zama-truss ezisebenza kahle kuyanda.
Izindlela Zokuzinza Zesakhiwo Se-Truss: I-Geometry Nokusatshalaliswa Komthwalo
Isimiso esiyisisekelo se-truss sisekunxantathu. Ngokungafani ne-polygon enezinhlangothi ezine, unxantathu awukwazi ukushintsha isimo ngaphandle kokushintsha ubude bezinhlangothi zawo. Lokhu kuqina kwejometri kuvumela ama-truss ukuthi amelane nokuguquguquka ngempumelelo. Ku-truss evamile, amalungu abhekana nokucindezeleka noma ukucindezelwa.
Isibonelo, ku-Pratt truss elula, amalungu aqondile aphatha ukucindezelwa kuyilapho amalungu aqondile ephatha ukungezwani. Onjiniyela basebenzisa i-Method of Joints ukubala amandla angaphakathi kuzo zonke izimpambano.
Ezimweni ezinhle zokuklama, i-designed kahlei-truss yensimbiingasekela isisindo sayo ngokuphindwe kaningi. Lokhu kusebenza kahle kuvela eqinisweni lokuthi ama-truss anciphisa kakhulu izikhathi zokugoba, okuvumela amalungu ukuthi athwale amandla aqondile kakhulu. Kunalokho agxila emandleni aqondile. Lokhu kugxila kuvumela izingxenye ezincane kanye nezindleko eziphansi.
Ama-trus amaningi ezimboni asebenzisa insimbi enamandla kakhulu ene-modulus yokunwebeka engaba ngu-200 GPa. Lokhu kuqina okuphezulu kuqinisekisa ukuthi isakhiwo sigcina isimo saso ngaphansi kwemithwalo esindayo yemvelo. Abaklami bavame ukusebenzisa imodeli yekhompyutha ukulingisa amaphuzu okucindezeleka ngaphambi kokuba kuqale ukwenziwa. Lokhu kunemba kunciphisa imfucuza yezinto ezibonakalayo cishe ngo-15% uma kuqhathaniswa nokwakhiwa kwemisebe yendabuko. Ngokugxila ekulayisheni kwe-axial, onjiniyela bafinyelela ububanzi obungenakwenzeka ngemisebe eqinile.
Ubuhle Bezinto Ezibonakalayo Zezakhiwo Ze-Truss: Insimbi vs. I-Aluminium
Ukukhetha izinto ezibonakalayo kunquma ukusebenza kanye nobude besikhathi se-truss. Insimbi ihlala iyisinqumo esiyinhloko sezinhlelo zokusebenza ezisindayo. Insimbi ye-Grade S355, evame ukusetshenziswa kumaphrojekthi aphesheya, inikeza amandla okukhiqiza angu-355 MPa. Ukuqina kwayo kuyenza ifaneleke kakhulu kumabhuloho kanye nokuqinisa okuphezulu. Ngokuphambene nalokho, ama-trus e-aluminium athola indawo ekukhiqizweni kwemicimbi kanye nezakhiwo zesikhashana.
I-Aluminium 6082-T6 inikeza amandla okukhiqiza angaba ngu-250 MPa kodwa inesisindo esingaphansi ngo-66% kunensimbi. Izibalo zibonisa ukuthi ukusebenzisa i-aluminium kunganciphisa izindleko zokuhamba ngo-40% ekusethweni kwesiteji sokubuka. Ngenkathi insimbi inikeza ukumelana nomlilo okuphezulu kanye nokuqina kwesikhathi eside, i-aluminium inikeza ukuphatheka okungenakuqhathaniswa.
Ukumelana nokugqwala nakho kuyahlukahluka phakathi kwalezi zinsimbi. Insimbi egayiwe imelana nokugqwala amashumi eminyaka, ngisho nasezindaweni ezisogwini. Kodwa-ke, i-aluminium ngokwemvelo yakha ungqimba lwe-oxide oluvikelayo. Lolu ngqimba luvimbela ukuwohloka kwesakhiwo okujulile ngaphandle kokwembozwa okwengeziwe. Abenzi besimanje bavame ukusebenzisa i-powder coating ukuze bathuthukise ubuhle kanye nokuvikelwa.
Emakethe yamanje, ama-trus ensimbi athatha cishe u-70% womkhakha wezimboni. I-aluminium ibusa indawo yokuzijabulisa neyombukiso ngenxa yokuthi kulula ukuyihlanganisa. Ukukhetha izinto ezifanele kuhilela ukulinganisela izindleko zokuqala, izidingo zesisindo, kanye nesikhathi esilindelekile sephrojekthi.
Ukwehluka Kwesakhiwo: Kusukela kuWarren kuya ku-Space Frames
Onjiniyela bakhetha izinhlobo ze-truss ngokusekelwe ezidingweni ze-span kanye nemigomo yobuhle. I-Warren truss, ebonakala ngonxantathu abalinganayo, inciphisa ubude bebonke bamalungu. Isebenza kahle kakhulu kuma-span aphakathi kwamamitha angu-20 no-100. Ezindaweni ezinkulu nakakhulu, njengezindawo zokugcina izindiza, abaklami basebenzisa ozimele besikhala. Lawa ma-truss e-3D asabalalisa imithwalo ngobukhulu obuthathu kunokuba ibe yindiza eyodwa nje.
Ucwaningo lusikisela ukuthi ozimele besikhala bafinyelela ubude obungaphezu kwamamitha ayi-150 kumaphrojekthi amakhulu akhethekile. Leli khono lidala ingaphakathi elikhulu nelivulekile lama-hangar nezikhungo zemihlangano. Kubunjiniyela bebhuloho, i-Howe truss isebenzisa amalungu aqondile ekucindezelweni, okuhambisana nemiklamo ethile enzima ngokhuni. Isofthiwe yesimanje manje ivumela ukwakheka okukhiqizayo. Le nqubo idala amaphethini e-truss alungiselelwe kahle asebenzisa izinto ezingaphansi ngo-20% kunezakhiwo zendabuko. Lawa mathuluzi edijithali aqinisekisa ukuthi igremu ngalinye lensimbi lifaka isandla ekuqineni kwesakhiwo.
Ngaphezu kwalokho, ama-truss akhethekile njenge-Fink truss anikeza ukwesekwa okuhle kakhulu kwezindawo zophahla zokuhlala. Uhlobo ngalunye lubhekana nenselele ethile yemishini. I-Warren truss inciphisa amaphuzu okushisela, okwehlisa izindleko zomsebenzi wokukhiqiza ngo-10%. Okwamanje, i-K-truss isiza ekuvimbeleni ukugoba emiklamo yamabhuloho amade kakhulu. Ukuhlukahluka kwezinhlobo zama-truss kuqinisekisa ikhambi lanoma yimuphi umbono wokwakha.
Umthelela Wezomnotho kanye Nokufakwa Kwezakhiwo Ze-Truss
Inani lezomnotho lama-truss lidlula ukonga kwezinto ezibonakalayo. Ngenxa yokuthi izingxenye zilungiswa kusengaphambili emafektri, umsebenzi owenziwa endaweni wehla kakhulu. Izifundo zibonisa ukuthi uphahla olusekelwe kuma-truss lufakwa ngokushesha ngo-30% kunezinhlelo zendabuko ze-beam-and-column. Lesi sivinini sinciphisa izindleko zezimali zabathuthukisi. Emakethe yamazwe ngamazwe, ama-truss ajwayelekile avumela ukuthunyelwa okuphumelelayo. Isitsha esijwayelekile esingamamitha angu-40 singabamba izingxenye zophahla lwendlu yokugcina impahla olungamamitha-skwele angu-500 uma senzelwe ukwakha izidleke.
Ngaphezu kwalokho, izindleko zokulungisa izisekelo zensimbi eziqinisiwe zihlala ziphansi. Impilo yesevisi ivame ukudlula iminyaka engama-60 ngokungenelela okuncane. Isidingo somhlaba wonke sezisekelo zensimbi kufanele sikhule ngo-5.5% minyaka yonke kuze kube ngu-2030. Lokhu kukhula kulandela ukwanda kwezimboni emazweni asafufusa. Lezi zifunda zidinga izindlela zokwakha ezisheshayo nezithembekile.
Ngaphezu kwalokho, inani eliphezulu lensimbi elahliwe lenza ama-trus abe ukukhetha okuzinzile. Ekupheleni kwempilo yesakhiwo, abanikazi bangaphinda basebenzise cishe u-98% wohlaka lwensimbi. Lokhu kuzungeza kukhanga abatshalizimali abagxile emigomweni yezemvelo, yezenhlalo, kanye neyokuphatha. Ukukhiqizwa ngaphandle kwendawo nakho kuthuthukisa ukulawulwa kwekhwalithi. Izilungiselelo zasefektri zivumela ukuhlolwa kwe-ultrasonic kwama-welds, okuqinisekisa izinga lempumelelo elingu-99.9% ensimini. Lokhu kuthembeka kunciphisa ukubambezeleka okubizayo kanye nezingozi zokuphepha ngesikhathi sesigaba sokwakha.
