Lub luj tshib classification
1. Raws li nws lub vojvoog ntawm curvature, nws tuaj yeem muab faib ua lub vojvoog ntevluj tshibthiab luv luv radius luj tshib. Lub luj tshib ntev txhais tau hais tias nws lub vojvoog ntawm curvature yog sib npaug li 1.5 npaug ntawm txoj kab uas hla ntawm cov yeeb nkab, uas yog, R = 1.5D. Lub luj tshib luv luv txhais tau hais tias nws lub vojvoog ntawm curvature yog sib npaug rau sab nraud ntawm cov yeeb nkab, uas yog, R = D. Hauv cov qauv, D yog lub luj tshib txoj kab uas hla thiab R yog lub vojvoog ntawm curvature. Lub luj tshib feem ntau yog 1.5D. Yog tias nws tsis tau qhia hauv daim ntawv cog lus raws li 1D lossis 1.5D, feem ntau siv cov qauv kev coj ua hauv Suav teb los ua kom zoo rau kev xaiv 1.5D yog GB / T12459-2005, GB / T13401-2005, thiab GB / T10752-1995
2. Raws li cov qauv duab, nws feem ntau yog lub luj tshib, square luj tshib, thiab lwm yam.
Qhov loj me ntawm lub luj tshib
Feem ntau, lub luj tshib, dabtsi yog khoov vojvoog, txoj kab uas hla, phab ntsa thickness thiab cov khoom yuav raug txiav txim tsuas yog tom qab paub cov ntaub ntawv hauv qab no.
Kev suav ntawm theoretical qhov hnyav ntawm lub luj tshib
1. Round luj tshib: (txoj kab uas hla - phab ntsa thickness) * phab ntsa thickness * coefficient * 1.57 * nominal txoj kab uas hla * ntau coefficient: carbon steel: 0.02466
Stainless hlau: 0.02491Alloy 0.02483
90 ° luj tshib (txoj kab uas hla - phab ntsa thickness) * phab ntsa thickness * coefficient (0.02466 rau carbon steel) * 1.57 * nominal txoj kab uas hla * ntau / 1000 = theoretical luj ntawm 90 ° luj tshib (kg)
2. Square luj tshib:
1.57 * R * perimeter ntawm lub qhov ncauj square * ntom * thickness
Kev suav ntawm lub luj tshib Yog tias qhov hnyav yog xam, koj tuaj yeem siv qhov hnyav / qhov hnyav / tuab los xam cov cheeb tsam, tab sis xyuam xim rau kev sib sau ntawm cov units.
1. Round luj tshib = 1.57 * R * caliber * 3.14;
2. Square luj tshib = 1.57 * R * ib puag ncig ntawm lub qhov ncauj square
R stands for dabtsi yog khoov vojvoog, 90 ° luj tshib xam txoj kev
