NCO TSEG: Fl yog cov kev nyab xeeb nthab. Nws yuav tsum tau siv ua ke nrog kev nkhaus ruaj ruaj. Nws los ntawm kev paub dhau los thiab sim. Nws yog ib tus nqi siv raws li kev ua haujlwm siab tshaj plaws.
Piv txwv li: lub portal crane kos duab
Kev xam cov txheej txheem ntawm qhov siab tshaj plaws thauj tau pom zoo raws li hauv qab no:
Ua ntej xaiv cov kev txhawb nqa cog qoob loo, cov khoom siv nyab xeeb li qub uas yuav tsum tau txiav txim siab rau tus tswv tsev 1. Portal Crane: FS = 1.45
Thaum qhov siab tshaj plaws lub nraaj yog paub, kev laij cov qauv ntawm nws load yog raws li hauv qab no:
1) Qhov siab tshaj plaws ua hauj lwm load ntawm yim-qib cua ntaus
axial quab yuam fa = q + a + o + g
Odolurning lub sijhawm m = Q × lmax + A× amax + W × r - o € o - g × g
2) Tsis hais txog cov cua hard zog, xav txog cov load ntawm 25% xeem thauj khoom
Axial Yuam Fa = 1.25 × Q + A + O + G
Ovolurning lub sijhawm m = 1.25 × kaum × lmax + ib × amax - o × o - g ×
Piv txwv li: cov kev ua haujlwm thauj khoom thiab qhov chaw nres nkoj Clamshell tau paub tias yog hauv qab no:
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
Ntau tshaj plaws ua haujlwm thauj cov cua fais fab ntawm qib 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 × 6.7 × 4.75 × 900 × 3
= 3943 knm
2) Tsis hais dua ntawm cua ntaus pob, xav txog qhov siab tshaj plaws load ntawm 25% xeem thauj khoom
FA = 1.25 × Q + A + O + G
= 325 +75 +450 +900
= 1750kn
M = 1.25 × q × lmax + ib × amax - o × o - g × g
= 325 × 23 + 75 × 11 × 45 × 0.75 × 3
= 5566.3 knm
3) Lub zog siab tshaj plaws ntsaws tsis hais tias muaj cua dag zog
FA = 1685 Kn
M = q × lmax + ib × amax - o × o - g × g
= 260 × 23 + 75 × 11 × 450 × 0.75 × 900 × 3
= 3767,5 knm
Load tus kab mob 2 yog siv los ua cov haujlwm ua haujlwm ntawm kev xam zoo li qub
Raws li sijhawm sijhawm 1, lub portal crane (tsoom thoob) yuav tsum tau txais kev txhawb nqa los ntawm peb kab ntawm cov menyuam-hom-rillary txhawb nqa:
Lub qub ntawm kev siv hluav taws xob thauj khoom ntawm kev txhawb nqa qeeb qeeb yog:
Fa '= 1750 KN × 1.45 = 2535 = 2537.5 Kn m' = 5566.3 knm × 1.45 = 8071.1 km
Cov kev muab cov kev ntsuas ntawm cov ntsia liaj qhov rooj yog:
Fa = 1750 kn m = 5566.3 knm
Raws li cov kev xam saum toj no, kev xaiv ntawm cov kabmob muaj peev xwm muaj kev tiv thaiv muaj peev xwm xaiv cov kev txhawb nqa qeeb ntawm 13 * .45.2000.002
Cov lus piav qhia saum toj no yog cov ncauj lus kom ntxaws kev xam txheej ntawmCov Kab Mob Slewingloj. Raws li cov kev xam pom tau, koj tuaj yeem xaiv qhov haumCov Kab Mob SlewingQauv hauv pebKhoom Catalog KhoomCov. Yog tias koj tsis paub yuav xam li cas, thov xav tiv tauj peb los ntawm email. Peb yuav pab koj lub siab kawg!
