1. Thaum lub sij hawm tu txheej txheem, vuam deformation ntawm tus choj crane tau pom, thiab nws cov deformation tswj tau dhau los ua qhov teeb meem ceev uas yuav tsum tau daws. Vim yog lub thawv kab teeb tsa ntawm tus choj crane, uas muaj ntau yam welds thiab cov qauv nyuaj, vuam kev nyuaj siab thiab deformation yog qhov tseem ceeb. Yog tias tsis tau txais kev tsim qauv tsim nyog thiab cov txheej txheem kev tsim kho, kev deformation yuav tshwm sim thaum lub sij hawm vuam, uas yuav cuam tshuam rau cov vuam zoo thiab tseem ua rau tsis muaj peev xwm txhim kho thiab siv cov qauv kom raug.
2. Nws yog ib qho tseem ceeb kom nkag siab txog qhov ua rau vuam deformation kom tsim nyog raws li qhov xwm txheej tshwj xeeb, txo qhov degree ntawm vuam deformation rau tus nqi me me, xyuas kom raug thiab tsim nyog siv cov qauv, thiab ua kom zoo dua qub. ntau yam kev ua tau zoo ntawm choj cranes, muab kev lees paub rau kev tsim kho zoo dua.
3. Feem ntau, lub ntsiab ua rau vuam deformation nyob rau hauv choj cranes yog tsis sib xws thaum tshav kub kub input. Qhov loj ntawm cov khoom siv hluav taws xob yog ze ze rau cov khoom siv thiab cov qauv ntawm cov vuam. Ob qho khoom siv thiab cov qauv tsim muaj feem cuam tshuam rau cov hlau txav nyob ib puag ncig cov cua sov, ua rau nws cuam tshuam los ntawm ob qho tib si sab hauv thiab sab nraud, ua rau muaj kev ntxhov siab deformation ntawm cov khoom siv vuam. Vuam deformation feem ntau muaj xws li shrinkage deformation (ntev thiab transverse shrinkage), khoov deformation, angular deformation, yoj deformation, twisting deformation, thiab lwm yam, uas yog reflected nyob rau hauv lub sab nrauv qauv ntawm tus choj crane, qhia lub zos uplift, distortion, dabtsi yog khoov, thiab twisting. .
4. Muaj ntau qhov laj thawj uas tuaj yeem ua rau cov teeb meem no thaum lub sij hawm vuam, xws li qhov loj ntawm qhov vuam seam tsis raug txaus, tus naj npawb ntawm vuam seams tsis ua raws li cov qauv uas tau teem tseg, qhov ua yuam kev tseem ceeb ntawm txoj haujlwm vuam thiab tsim. txoj hauj lwm, thermal thiab lub cev tsis muaj zog ntawm cov khoom siv vuam, cov txheej txheem kev tsim kho tsis zoo rau kev ua tiav qhov zoo tshaj plaws vuam lub xeev, xaiv vuam tsis, thiab lwm yam. Txhua qhov txuas tshwj xeeb yuav tsum tau ua tib zoo tuav kom ua tiav cov txiaj ntsig xav tau.
