ICYITONDERWA: FL ni ikintu cyumutekano ufite imbaraga. Igomba gukoreshwa hamwe na Dinmic yikoreye umurongo. Bituruka kuburambe no kugerageza. Nigaciro kerekana gushingiye kumutwaro ntarengwa.
Kurugero: igishushanyo cya portal crane
Uburyo bwo kubara bwumutwaro ntarengwa birasabwa kuburyo bukurikira:
Mbere yo guhitamo infashanyo, ibintu byumutekano uhamye FS bigomba gufatwa nkibyakiriye bigomba kugenwa muri gahunda ya 1. PORTAL CRARE: FS = 1.45
Iyo umutwaro ntarengwa uzwi, formula yo kubara yumutwaro wacyo niyi ikurikira:
1) Umutwaro ntarengwa wakazi wingufu zumuyaga umunani
imbaraga za axial fa = q + a + o + g
Gukuraho umwanya m = q × lmax + a × Amax + w × r - o × o - g × g
2) Utitaye ku mbaraga z'umuyaga, tekereza ku mutwaro wa 25%
Ingufu za Axial FA = 1.25 × q + a + o + g
Kurangiza umwanya m = 1.25 × × × × lmax + a × Amax - o × o - g ×
Urugero: Umutwaro wakazi na amplitude yicyambu cya Clamshell kizwi ku buryo bukurikira:
Q = 260 kn lmax = 23 m 1max = 23m
A = 75 KN Amax = 11 m Amax = 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
Imitwaro ntarengwa yakazi yimbaraga z'umuyaga kurwego rwa 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 × 050 × 75 × 900 × 3 × 3
= 3943 KNM
2) Utitaye ku mbaraga z'umuyaga, tekereza ku mutwaro ntarengwa w'akazi wa 25%
FA = 1.25 × q + a + o + g
= 325 +75 +450 +900
= 1750kn
M = 1.25 × × × LMAX + a × Amax - O × O - G × g
= 325 × 23 + 75 × 11 × 45 × 45 × 900 × 3
= 5566.3 KNM
3) Umutwaro ntarengwa ukora utitaye ku mbaraga z'umuyaga
FA = 1685 KN
M = × × lmax + a × Amax - O × o - g × g
= 260 × 23 + 75 × 11 × 450 × 055 × 900 × 3
= 3767.5 KNM
Imiterere yimitwaro 2 ikoreshwa nkumutwaro wakazi wo kubara
Ukurikije gahunda ya 1, Crane ya Portal (indobo ya grab) igomba gushyigikirwa numurongo utubiri winkunga-ya Roller-Ubwoko buzunguruka:
Umutwaro uhagaze ku nkunga ya Rotary ni:
Fa '= 1750 KN × 1.45 = 2537.5 KN M' = 5566.3 KNM × 1.45 = 8071.1 KNM
Umutwaro wo kubara wa Bolt ni:
FA = 1750 KN M = 5566.3 KNM
Nk'uko ibisubizo byavuzwe haruguru, guhitamo umuyoboro watangaga birashobora kwiyemeza guhitamo inkunga ya 13 * .45.2000.002
Ibisobanuro byavuzwe haruguru nuburyo burambuye bwo kubarakwisigaingano. Ukurikije ibisubizo byo kubara, urashobora guhitamo ibikwiyekwisigaicyitegererezo muri tweIgicuruzwa. Niba utazi kubara, nyamuneka twandikire ukoresheje imeri. Tuzagukorera n'umutima wawe wose!
