1. Tsim
Rau txhua qhov haujlwm, qhov tseem ceeb yog tsim, thiab nws qhov zoo thiab qhov tsis zoo cuam tshuam rau tus nqi, qhov zoo, kev tsim kho nyuaj thiab lub sijhawm tsim kho ntawm qhov project.Txawm hais tias muaj qee qhov kev tsim qauv zoo hauv peb lub tebchaws, feem ntau ntawm lawv muaj qee qhov teeb meem tsim.Qhov tsim tsis tsim nyog tsis yog tsuas yog coj kev poob rau kev lag luam thiab nce kev nqis peev, tab sis kuj buryes zais kev phom sij rau qhov zoo ntawm choj engineering thiab cuam tshuam kev tsim kho choj.advanced technology.Tshwj xeeb tshaj yog, kev tsim cov qauv ntawm cov choj steel yeej ua raws li cov qauv qub, siv cov qauv uas twb muaj lawm yam tsis muaj kev xav tshiab, thiab tsis tshua siv cov ntaub ntawv tshiab lossis cov qauv tshiab, thiab tsis tuaj yeem tsim raws li qhov tseeb ntawm thaj chaw thiab ib puag ncig ib puag ncig.Tsis tas li ntawd, nyob rau hauv cov txheej txheem tsim, qhov kev ua tau zoo ntawm cov qauv hlau tsis suav nrog, thiab lub zog coefficient feem ntau tau nce siab txhawm rau txhawm rau ua kom muaj txiaj ntsig ruaj khov, ua rau cov khoom siv thiab cov ntaub ntawv pov tseg tsis tsim nyog.Tsis tas li ntawd, nyob rau hauv kev suav cov tsis, qhov kev siv tiag tiag tsis suav tias yog txaus, uas ua rau tus choj tsis ruaj khov thiab muaj kev ntxhov siab tawm los thaum siv cov txheej txheem.Cov no yog cov teeb meem tshwm sim hauv steel choj tsim.
2. Zoo
Hauv kev xaiv cov khoom siv rauchoj steel qauv, kev saib xyuas yuav tsum tau them rau cov teeb meem zoo, vim hais tias rau cov choj, lub cev tseem ceeb ntawm kev quab yuam yog hlau thiab pob zeb, yog li qhov kev txiav txim siab cuam tshuam rau kev ua haujlwm ntawm cov choj yog qhov zoo ntawm cov qauv hlau.Tus qauv tsim yuav tsum tau ua raws li nruj me ntsis thaum lub sij hawm tsim, thiab tus qauv tsim yuav tsum tsis txhob txo qis arbitrarily.Tsis tas li ntawd, cov qauv hlau yuav tsum tau ua raws li cov kev qhia tshwj xeeb, thiab txhua txoj kev yuav tsum tau ua nruj me ntsis kom ntseeg tau tias kev tsim vaj tsev zoo ntawm tus choj thiab tsis txhob muaj xwm txheej.
3. Corrosion tshwm sim
Lub ntsiab tseem ceeb ntawm cov hlau yog hlau, yog li ntuj corrosion yog inevitable rau steel, uas kuj yog ib qho tseem ceeb uas ua rau muaj kev phom sij rau tus choj tsim.Yog tias cov qauv steel corrodes rau ib qho twg, nws yuav ua rau tus choj thiab nws lub neej kev pab cuam loj heev.Corrosion yuav txo qhov kev quab yuam-kev muaj peev xwm ntawm tus qauv nws tus kheej, ua rau tag nrho lub zog ntawm tus choj tsis ruaj khov nyob rau hauv qhov kev txiav txim ntawm kev thauj mus los, thiab qee qhov chaw uas muaj corrosion loj yuav tshwm sim dabtsi yog khoov, thiab kev sib tsoo loj yuav tshwm sim, nrog rau kev puas tsuaj loj. .
4. Vuam txheej txheem
Lub vuam zoo muaj qhov muaj zog ntawm kev ua haujlwm ntawm cov txheej txheem, thiab tuav txoj haujlwm tseem ceeb ntawm cov khoom cuam tshuam rau qhov zoo ntawm cov txheej txheem.Nws lub hwj chim feem ntau yog los ntawm ob yam: ntawm ib sab, nws yog lub rationality ntawm tus txheej txheem formulation;ntawm qhov tod tes, nws yog qhov hnyav ntawm cov txheej txheem tua.Cov qauv steel feem ntau yog ua ke los ntawm cov txheej txheem vuam.Yog tias cov txheej txheem vuam tsis nruj me ntsis ua raws li cov txheej txheem tsim nyog, vuam tsis zoo yuav tshwm sim.Welding defects tsis tsuas yog coj ntau yam teeb meem rau kev tsim khoom, tab sis kuj yuav ua rau muaj kev puas tsuaj loj.Raws li kev txheeb cais, feem ntau ntawm cov qauv hlau raug xwm txheej yog tshwm sim los ntawm kev sib tsoo vuam.Qhov zoo ntawm vuam qhov tsis zoo no feem ntau yuav tshwm sim hauv cov ntsiab lus vuam ntawm cov qauv hlau.Cov ntsiab lus vuam no yuav cuam tshuam rau kev ruaj ntseg ntawm tag nrho cov quab yuam ntawm cov qauv hlau.Yog tias tsis tiv thaiv, nws yuav faus qhov kev phom sij zais cia.
5. Cov qauv tsim tsis zoo
Cov ntsiab lus tsis zoo ntawm cov txheej txheem yuav ua rau geometric stress concentration, uas yog yooj yim overlooked nyob rau hauvsteel qauvtsim, thiab nws kuj yog ib qho ntawm cov laj thawj uas yuav ua rau muaj kev sib tsoo ntau dua.Vim qhov kev nthuav dav tsis zoo ntawm cov qauv hlau ntawm tus choj, qhov kev nyuaj siab ntawm tus choj yog cov concentrated thiab superimposed thaum siv tus choj.Raws li kev nqis tes ua ntawm cov khoom sib txawv, cov kev puas tsuaj me me txuas ntxiv mus, ua rau nthuav dav ntawm kev qaug zog, thiab thaum kawg ua rau muaj xwm txheej.Tus choj yog ib qho qauv tsim, thiab qee cov ntsiab lus tsis pom zoo yuav ua rau kev ntxhov siab ntawm tag nrho tus choj.Yog tias muaj kev ntxhov siab los yog kev ntxhov siab qaug zog tshwm sim hauv cov qauv me me, nws yooj yim rau deform thiab ua rau cov qauv hlau tawm los.
