Chaw trusses
Ib qho chaw nres tsheb ciav hlau (lossis chaw thav duab) yog cov txheej txheem sib txawv uas ua haujlwm ntawm cov qauv kab ke Txhim kho . Cov kab ke no tau tsim los daws cov nyom, thiab torsion, thiab torsion, thiab torsion
Khoom Taw qhia
Cov yam ntxwv tseem ceeb
- Daim duab peb sab geometry: Chav tsev yog tetrahedron lossis pyramid-puab cell tsim los ntawm cov tswvcuab sib txuas ua ke thiab ruaj khov.
- Peb-seem load faib faib khoom: kis tau kis raws peb lub taus (x, y, z), txo qis kev ntxhov siab thiab deflection.
- Modularity: Ua ntej-ntaub rov ua dua cov khoom uas yuav tso cai ua ke ua ke thiab thev naus laus zis.
- Kev Ua Kom Zoo: Ua kom muaj lub zog siab nrog cov khoom siv tsawg heev, zoo tagnrho rau kev siv ntev ntev.
Txheej txheem sib xyaw
Chaw trusses muaj cov peb feem ntau cov khoom siv:
Cov Tswv Cuab (Rods / Beams)
- Cov Khoom Siv: High-zog steel, alloys alloys, lossis siab tshaj composites .
- Hla-ntu: Vide Hollow tshooj (AV), square hollow tshooj (shs), lossis cov duab plaub {2}
- Ua haujlwm: Ua raws li compression los yog nro}}} kev tshaj plaws ntawm txoj kab-rau-tuab piv tsis txhob sib tw {}}
Tus medes
- Hom:
- cov pob qij txha sib hloov: pub multi-directional sib hloov (ib txwm muaj cov qauv kev lag luam) .
- pob txha pob qij txha: txwv tsis pub siv kev sib hloov rau cov axes tshwj xeeb (siv nyob hauv ru tsev lossis choj) .
- Tsim: precision-machined los ua kom muaj kev sib luag thauj khoom thauj khoom thauj khoom. welded, bolted, lossis gusseted sib txuas.
Caws lub tshuab
- Cov tswv cuab theem nrab tswj thawj trusses tawm tsam tom qab lossis cua loads .
- suav nrog kab pheeb ces kaum kev zawm hniav, x-bracing, lossis ib puag ncig caij thav lug .
Mechanics ntawm qhov chaw trusses
01
Thauj Khoom
Loads thov ntawm cov nodes pauv los ntawm axial rog hauv cov tswv cuab {{}} Piv txwv:
- ib lub ru tsev ntsug ntawm lub ru tsev ntawm cov kab sib tsoo rau hauv compressive thiab tensile rog raws kev sib tshuam cov tswv cuab .
- cua shear yog resisted los ntawm kab pheeb ces kaum bracing thiab triangulated shear shear webs .
02
Kev Tshawb Xyuas Kev Ruaj Ntseg
- Ntiaj teb stability: tsis kam rau buckling nyob rau hauv compressive loads.}) siv tau ruaj khov.
- Cov neeg sawv cev hauv zos: Tiv thaiv cov tswv cuab los ntawm kev tsis txaus siab nyob rau hauv kev ntxhov siab nyob rau hauv kev ntxhov siab {1} Tus tswv cuab baser .
03
Rov ua dua
- cov tswv yim indeterminate: cov tswv cuab tshaj tshaj plaws muab cov khoom lag luam rov qab, kev siv hluav taws xob rov ua yog tias ib qho kev tsis ua tiav.
- Kev suav ntxiv: suav nrog (tag nrho cov tswv cuab uas xav tau) / yam tsawg kawg nkaus uas yuav tsum tau ua.
Cov Ntawv Thov
Space trusses excel in large-span, lightweight, and complex geometries. Common uses include:
Cov qauv kws kos duab
- Cov kev ua si Arenas: Ru tsev tshuab rau chaw ntau pob (e .!
- Cov tsev sau ntawv tso cai: ru tsev nkhaus rau tsev cia puav pheej lossis kev lag luam qhia.
- Tshav dav hlau Terminals: Ntev ntev canopies nrog kev teeb pom kev zoo thiab hvac duct
01
Muaj Infrastructure
- Warehouses: High-bay cia chaw nrog30- 'meter' me me spans {}}
- Lub rooj sib tw Hoobkas: Modular Trusses rau kev sib dhos cov nroj tsuag, txo qis downtime thaum nruab rau {}}
- txias cia: insulated chaw thav duab nrog polyurethane ua npuas ncauj panels.
02
Tsheb thauj mus los
- Txuas hniav: Neeg taug kev Skebrides thiab ntev-ntev ntev txuas hniav .
- Cov chaw nres tsheb ciav hlau glulam glulam ntoo-chaw thav duab hybrids rau eco-phooj ywg tsim
03
Aerospace thiab tubrog nkoj
- satellite antennas: siv cov chaw ntim khoom siv rau telescopic .
- Nkoj decks: corrosion-resistant txhuas trusses rau ntug dej platform .
04
Cov qauv ib ntus
- Exitition Lus Sawv: Reusable Trusses rau kev ua lag luam fairs.
- Cov Tuav Kev Puas Tsuaj Loj: Cov Tsev Sib Ncauj Ceev Ceev Ceev .
05
Chaw trusses sawv cev rau cov txheej txheem sib txawv, ua kom muaj kev sib tw, thiab cov qauv kev lag luam tsis zoo, thiab cov chaw sib txuas lus zoo nkauj, thiab cov chaw sib txuas lus ntxiv mus thawb cov ciaj ciam ntawm dab tsi ua tau nyob rau hauv peb-seem engineering.
Cim npe nrov: Chaw trusses, Tuam Tshoj, cov chaw muag khoom, chaw tsim khoom, Hoobkas, siv, hauv Tshuag, tus nqi qis, luv nqi, ntau
