Cherechedza: fL ndiyo ine simba yekuchengetedza chinhu.Inofanira kushandiswa pamwe chete ne dynamic load curve.Zvinobva pane zvakaitika uye kuedza.Iyo ireferensi kukosha kwakavakirwa pane yakanyanya kushanda mutoro.
Semuenzaniso: Iyo portal crane dhayagiramu
Iyo yekuverenga nzira yekuremedza yakanyanya inokurudzirwa sezvizvi:
Usati wasarudza tsigiro yekutenderera, iyo static kuchengetedza factor fs iyo inofanirwa kutariswa kune muenzi inofanirwa kutariswa, iyo inogona kuwanikwa muchirongwa 1. Portal crane:fs=1.45
Kana iyo yakanyanya static mutoro ichizivikanwa, iyo yekuverenga formula yemutoro wayo ndeiyi inotevera:
1) huwandu hwekushanda kwesimba remhepo sere-level
axial simba Fa = Q + A + O + G
nguva yekupidigura M = Q × lmax + A × amax + W × r – O × o – G × g
2) Pasinei nesimba remhepo, funga mutoro we25% test load
axial simba Fa = 1.25 × Q + A + O + G
nguva yekupidigura M = 1.25 × Q × lmax + A × amax – O × o – G ×
Muenzaniso: mutoro wekushanda uye amplitude yeclamshell port inozivikanwa seizvi:
Q = 260 kN lmax = 23 m 1max=23m
A = 75 kN max = 11 m max=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
Yakanyanya kushanda mutoro wesimba remhepo padanho 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) pasinei nesimba remhepo, funga nezvehuwandu hwekushanda kwe25% test load
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）yakanyanya kushanda mutoro zvisinei nesimba remhepo
Fa = 1685 kN
M = Q×lmax + A×amax – O×o – G×g
= 260 × 23 + 75 × 11×450 × 0.75×900 × 3
= 3767.5 kNm
Mutoro mamiriro 2 inoshandiswa semutoro wekushanda we static calculation
Zvinoenderana nehurongwa 1, iyo portal crane (yekubata bhaketi) inofanirwa kutsigirwa nemitsara mitatu yekutenderera-mhando yerutsigiro:
Iyo static referensi mutoro werutsigiro wekutenderera ndewekuti:
Fa＇ = 1750 kN × 1.45 = 2537.5 kN M＇= 5566.3 kNm × 1.45 = 8071.1 kNm
Kuverengera mutoro webhoti ndewekuti:
Fa = 1750 kN M = 5566.3 kNm
Zvinoenderana nemhedzisiro yekuverenga iri pamusoro, kusarudzwa kweiyo bearing capacity curve inogona kutsunga kusarudza tsigiro inotenderera ye13 * .45.2000.002
Tsananguro iri pamusoro ndiyo yakadzama yekuverenga nzira yekuurayasaizi.Maererano nemhinduro dzekuverenga, unogona kusarudza yakakodzerakuurayamuenzaniso weduproduct catalog.Kana iwe usingazive maverengero, ndapota inzwa wakasununguka kutibata nesu neemail.Tichakushandirai nemoyo wese!
