Thaum tsim ib qho khoom siv hluav taws xob peb-dimensional, nws yog ib qho tsim nyog los muab lub koom haum tsim qauv engineering nrog cov kev xav tau ntawm cov txee rau hauv av. Muaj qee tus neeg tsis paub yuav suav li cas thaum lawv ntsib qhov teeb meem no, thiab feem ntau tig mus rau cov neeg tsim khoom kom pab. Txawm hais tias feem ntau txhim khu kev qha cov tuam txhab lag luam tuaj yeem muab cov ntaub ntawv sib xws, cov lus teb ceev kuj qeeb, thiab lawv tsis tuaj yeem teb tus tswv cov lus nug raws sijhawm. Tsis tas li ntawd, yog tias koj tsis paub txog txoj kev suav, koj tsis tuaj yeem txiav txim seb puas muaj teeb meem nrog cov ntaub ntawv koj tau txais, thiab koj tseem tsis muaj lub tswv yim. Ntawm no yog ib txoj kev xam yooj yim uas tsuas yog xav tau lub tshuab xam zauv xwb.
Feem ntau, nws yog ib qho tsim nyog los tawm tswv yim tias cov khoom ntawm lub txee rau hauv av muaj ob yam khoom: concentrated load thiab nruab nrab load: concentrated load yog hais txog cov concentrated quab yuam ntawm txhua kem nyob rau hauv av, thiab lub general unit yog qhia nyob rau hauv tons; nruab nrab load hais txog chav tsev ntawm lub txee cheeb tsam. Cov kabmob muaj peev xwm feem ntau qhia hauv tons ib square meter. Cov hauv qab no yog ib qho piv txwv ntawm cov kab hluav taws xob ntau tshaj plaws. Cov khoom pallet tau teem rau ntawm lub txee raws li qhia hauv daim duab hauv qab no:
Txhawm rau kom nkag siab yooj yim, daim duab khaws cov txheej txheem ntawm ob qhov chaw nyob ib sab ntawm ib qho ntawm cov txee, thiab txhua qhov chaw tuav ob lub pallets ntawm cov khoom. Qhov hnyav ntawm chav tsev pallet yog sawv cev los ntawm D, thiab qhov hnyav ntawm ob lub pallet yog D * 2. Ua ib qho piv txwv, qhov hnyav ntawm ob lub pallets ntawm cov khoom yog sib npaug ntawm plaub kab 1, 2, 3, thiab 4, yog li qhov hnyav ntawm txhua kem yog D * 2/4 = 0.5 D, thiab tom qab ntawd peb siv Cov Kab No 3 ua piv txwv. Ntxiv nrog rau qhov seem ntawm cov khoom thauj sab laug, tus lej 3 kem, nrog rau 4, 5, thiab 6, kuj yuav tsum tau muab qhov hnyav ntawm ob lub pallet ntawm sab xis ntawm qhov sib npaug. Cov txheej txheem suav yog tib yam li ntawm sab laug compartment, thiab qhov sib koom hnyav kuj yog 0.5 D, yog li lub nra ntawm No. 3 kem ntawm txheej txheej no tuaj yeem yooj yim rau qhov hnyav ntawm lub pallet. Tom qab ntawd suav pes tsawg txheej ntawm lub txee muaj. Muab qhov hnyav ntawm ib lub pallet los ntawm tus naj npawb ntawm cov khaubncaws sab nraud povtseg kom tau cov concentrated load ntawm lub txee.
Tsis tas li ntawd, ntxiv rau qhov hnyav ntawm cov khoom, lub txee nws tus kheej kuj muaj qee qhov hnyav, uas tuaj yeem kwv yees raws li qhov muaj txiaj ntsig zoo. Feem ntau, tus qauv pallet khib tuaj yeem kwv yees raws li 40kg rau txhua qhov chaw thauj khoom. Cov mis laij lej yog siv qhov hnyav ntawm ib lub pallet ntxiv rau tus kheej qhov hnyav ntawm ib qho khoom thauj khoom thiab muab faib los ntawm cov txheej txheem. Piv txwv li, chav tsev cargo hnyav 700kg, thiab muaj 9 txheej ntawm txee nyob rau hauv tag nrho, yog li cov concentrated load ntawm txhua kem yog (700 + 40) * 9/1000 = 6.66t.
Tom qab qhia txog cov concentrated load, cia saib qhov nruab nrab load. Peb delineate qhov projection cheeb tsam ntawm ib co cargo cell raws li qhia nyob rau hauv daim duab hauv qab no, thiab qhov ntev thiab dav ntawm lub cheeb tsam yog sawv cev los ntawm L thiab W raws.
Muaj ob lub pallets ntawm cov khoom ntawm txhua lub txee nyob rau hauv qhov projected cheeb tsam, thiab xav txog qhov hnyav ntawm lub txee nws tus kheej, qhov nruab nrab load tuaj yeem muab faib los ntawm qhov hnyav ntawm ob lub pallet ntxiv rau tus kheej qhov hnyav ntawm ob lub rhawv, thiab tom qab ntawd faib los ntawm qhov hnyav ntawm ob lub pallets. projected cheeb tsam. Tseem coj cov khoom thauj ntawm 700kg thiab 9 rhawv ua piv txwv, qhov ntev L ntawm qhov projected cheeb tsam hauv daim duab yog xam li 2.4m thiab W li 1.2m, ces qhov nruab nrab load yog ((700 + 40) * 2 * 9 1000/(2.4*1.2) = 4.625t/m2.
