Tuhipoka: Ko te fL te take haumaru hihiri.Me whakamahi tahi me te anau kawenga hihiri.Ka puta mai i te wheako me te whakamatautau.He uara tohutoro i runga i te nui o te kawenga mahi.
Hei tauira:Ko te hoahoa warou tomokanga
Ko te tikanga tatau mo te utaina nui e taunakitia ana e whai ake nei:
I mua i te kowhiri i te tautoko hurihuri, me whakatau te take haumaru pateko fs e tika ana kia whakaarohia mo te kaihautu, ka kitea i te rarangi 1. Warou Portal:fs=1.45
Ina mohiohia te morahi o te kawenga pateko, ko te tauira tatau o tana kawenga e whai ake nei:
1) te kawenga mahi morahi o te kaha hau e waru taumata
topa tuaka Fa = Q + A + O + G
taima huri M = Q × lmax + A × amax + W × r – O × o – G × g
2)Ahakoa te kaha o te hau, whakaarohia te kawenga o te 25% te kawenga whakamatautau
topa tuaka Fa = 1.25 × Q + A + O + G
taima huri M = 1.25 × Q × lmax + A × teitei – O × o – G ×
Tauira: ko te kawenga mahi me te kaha tiwerawera o te tauranga clamshell e mohiotia ana e whai ake nei:
Q = 260 kN lmax = 23 m 1max=23m
A = 75 kN teitei = 11 m teitei=11m
O = 450 kN o = 0.75 m o=0.75m
G = 900 kN g = 3 m g=3m
W = 27 kN r = 6.5 m1) r=6.5m
Te kawenga mahi morahi o te mana hau i te taumata 8
Fa = Q + A + O + G
=260 + 75 + 450 + 900
=1685 kN
M = Q×lmax + A×amax + W×r – O × o – G× g
=260 × 23 + 75 × 11 + 27 ×6.5×450 ×0.75×900 × 3
= 3943 kNm
2) ahakoa te kaha o te hau, whakaarohia te nui o te kawenga mahi o te 25% te kawenga whakamatautau
Fa = 1.25×Q + A + O + G
=325 +75 +450 +900
= 1750kN
M = 1.25×Q×lmax + A×amax – O×o – G×g
= 325 × 23 + 75 × 11×45 × 0.75×900 × 3
= 5566.3 kNm
3) te kawenga mahi morahi ahakoa te kaha o te hau
Fa = 1685 kN
M = Q×lmax + A×amax – O×o – G×g
= 260 × 23 + 75 × 11×450 × 0.75×900 × 3
= 3767.5 kNm
Ko te ahua o te utaina 2 ka whakamahia hei kawenga mahi o te tatauranga pateko
E ai ki te rarangi 1, me tautoko te warou tomokanga (peere hopu) e toru nga rarangi o te tautoko hurihuri momo roera:
Ko te kawenga tohutoro pateko o te tautoko hurihuri ko:
Fa' = 1750 kN × 1.45 = 2537.5 kN M'= 5566.3 kNm × 1.45 = 8071.1 kNm
Ko te kawenga tatau o te poupou ko:
Fa = 1750 kN M = 5566.3 kNm
E ai ki nga hua o te tatauranga i runga ake nei, ka taea te whakatau i te kowhiringa o te pihinga kaha ki te kowhiri i te tautoko hurihuri o 13 * .45.2000.002
Ko te whakaahuatanga i runga ake nei ko te tikanga tatauranga taipitopito oslewing bearingrahi.E ai ki nga hua tatauranga, ka taea e koe te whiriwhiri i nga mea e tika anaslewing bearingtauira i roto i to tatourārangi hua.Mena kaore koe e mohio ki te tatau, tena koa waea mai ki a maatau ma te imeera.Ka mahi matou ki a koe ma te ngakau katoa!
