Cov khoom caij nplooj ntoos hlav xws li hlau stampings yog dav siv nyob rau hauv peb lub neej txhua hnub. Nrog rau kev paub txog science thiab technology, tib neeg tab tom xav kom muaj kev sib tw hlau. Hauv particular, cov kev cai ntawm kev ua haujlwm zoo thiab kev siv tshuab zoo siab heev.
Hauv lub Hoobkas hluav taws xob hauv lub tuam txhab, cov khoom siv kom zoo tshaj plaws rau kev thim nyiaj yog nruj heev. Yog li, peb yuav tsum nruj me ntsis tswj cov duab thiab qhov loj me ntawm qhov chaw thwj: Thawj yog qhov uas yuav tsum tau ua rau cov dabtsi yog khoov rau:
1. Cov duab ntawm txoj hlua khoov yuav tsum yog cov kabmob ua kom tsawg, thiab lub vojvoog sibtshaj yuav tsum tsis txhob pub tsawg tshaj qhov tsawg ntawm txoj hlua uas tau tso cai los ntawm cov khoom.
2, thaum khoov nrog qhov, kom tsis txhob muaj qhov deformation
3. Lub ntug qhov nkhaus luv heev yuav tsum yooj yim tsim, yog li ncaj nraim ntawm qhov ntug qhov yuav tsum yog H> 2. Yog tias H yuav tsum tau luv, nws yuav tsum tsim kom muaj ib qho tsim nyog kom nce H, thiab tom qab ntawd hlais ntxiv hlau tom qab khoov.
Ua raws li qhov yuav tsum tau muaj cov duab kos:
1. Cov duab kos yuav tsum yooj yim thiab symmetrical nyob rau hauv tsos thiab tsis txhob yuav tob. Yuav kom txo cov duab sib sib zog nqus, nws yooj yim rau kev tsim.
2. Lub voj voog fillet ntawm daim duab daim duab tsis tuaj yeem ua rau txoj kev pab cuam. Txwv tsis pub, nws yuav ua rau cov duab sib sib zog nqus thiab sib tw ua haujlwm. Nws tseem yuav ua rau kom muaj pwm tsawg, thiab nws yuav tsim cov khoom pov tseg thiab nce nqi.
