INkqubo yeSithuba seSithuba seNsimbi i-90m yeProjekthi yeYadi yamalahle eSpan
UFakelo loYilo lweSakhelo seSithuba:
Le projekthi yi-arched space frame / ubude buziimitha ezingama-49 / ubude bubonke buziimitha ezingama-633 / ubude buziimitha ezingama-76.3.
Iprojekthi ithatha isakhelo sesithuba sentsimbi, ifom exhasayo yinkxaso ye-chord esezantsi, ibholithi edibeneyo yebhola, kunye negridi yenqwelomoya yephiramidi ephindwe kabini.Isakhelo segridi sixhaswa kwiikholamu zekhonkrithi kumacala omabini, kwaye izixhaso zixhomekeke kwiintloko zekholomu zekholamu zekhonkrithi.I-electrodes ye-welding kunye neengcingo ezisetyenziselwa i-welding kufuneka zihlangabezane neemfuno ezifanelekileyo zemigangatho yesizwe yangoku.Ukuwelda phakathi kweentsimbi ze-Q235B kwamkela i-E43 series electrode, kunye ne-welding phakathi kweentsimbi ze-Q345B zisebenzisa i-E50 series electrode.
Isakhelo sendawo yentsimbi sibalwa kwaye siyilwe yisoftware ye-MST2020.
Ukongeza kokuhlangabezana neemfuno zekhowudi yezinto eziphathekayo kazwelonke, intsimbi esetyenziswe kule projekthi kufuneka ihlangabezane nezi mfuno zilandelayo:
a) Umlinganiselo wexabiso elilinganisiweyo lomlinganiselo wemveliso yentsimbi ukuya kwixabiso elilinganisiweyo lamandla obunzima akufanele libe ngaphezu kwe-0.85;
b) Intsimbi kufuneka ibe namanyathelo okuvelisa acacileyo, kwaye i-elongation kufuneka ibe ngaphezu kwe-20%;
c) Intsimbi kufuneka ibe ne-weldability elungileyo kunye nokuqina kwempembelelo efanelekileyo;
Uyilo lwesakhelo isithuba sentsimbi yamkela i-3D3S (uguqulelo 14.0) uyilo lwesoftware yesakhiwo sombhobho woyilo oluncediswa yikhompyuter kunye nenkqubo yokuvelisa ukwenza uhlalutyo lwangaphakathi lwamalungu kunye noyilo oluzenzekelayo loxinzelelo olupheleleyo kwi-microcomputer, kunye ne-self- ubunzima bomthwalo wesakhelo sendawo yentsimbi ngokuzenzekelayo bubekwe phezulu kuhlalutyo lwangaphakathi lwamandla.
Ubude obubaliweyo bentonga ngu-L0 = L, kwaye umlinganiselo we-slenderness wentonga engundoqo ubophe intonga ≤ 200 kunye ne-compression rod ≤ 150. Umlinganiselo we-slenderness wezinye iintonga zibophe intonga ≤ 250, intonga yoxinzelelo ≤ 180.
