Dab tsi yog qhov nrawm nrawm? Nws cov kev cai yog dab tsi?
Kev nrawm nrawm, tseem hu ua pob nrawm, yog cov chaw tsheb thauj mus los tau teeb tsa ntawm txoj kev loj kom qeeb tsheb hla. Cov duab feem ntau yog strip-zoo li, tab sis kuj taw tes-zoo li; cov khoom siv tsuas yog roj hmab, tab sis kuj yog hlau; Feem ntau daj thiab dub yog siv los nyiam qhov muag pom, kom txoj kev nto yog me ntsis arched kom ua tiav lub hom phiaj ntawm lub tsheb deceleration. Cov roj hmab deceleration siv yog ua los ntawm cov khoom siv roj hmab, cov duab yog txoj kab nqes-zoo li, thiab cov xim feem ntau yog daj thiab dub. Nws yog tsau ntawm txoj kev kev sib tshuam nrog expansion screws thiab yog ib qho chaw ruaj ntseg rau tsheb deceleration. Lub npe tshawb fawb yog roj hmab deceleration ridge, uas yog tsim raws li lub kaum sab xis ntawm lub log tsheb thiab cov roj hmab tshwj xeeb rau hauv av thaum lub tsheb khiav, thiab yog ua los ntawm cov roj hmab tshwj xeeb.
Cov kev cai dav dav rau roj hmab ceev pob (ridges):
1. Cov roj hmab deceleration ridge yuav tsum tau tsim ua ke, thiab sab nrauv yuav tsum muaj kab txaij los ua kom adhesion.
2. Txhua chav deceleration ridge yuav tsum muaj cov khoom siv uas muaj kev cuam tshuam, uas yooj yim rau kev txheeb xyuas thaum hmo ntuj thiab ntsib cov kev taw qhia ntawm lub tsheb.
3. Qhov saum npoo yuav tsum tsis muaj qhov pores, tsis muaj qhov pom tseeb khawb, tsis muaj cov khoom siv, xim tsis sib xws thiab tsis muaj flash.
4. Lub npe ntawm lub tsev tsim khoom yuav tsum tau nias rau ntawm qhov chaw ntawm cov roj hmab deceleration ridge.
5. Yog tias bolts siv los txuas rau hauv av, lub qhov ntsia hlau yuav tsum yog qhov sib tsoo qhov.
6. Txhua chav tsev ntawm qhov deceleration ridge yuav tsum tau txuas nrog kev ntseeg siab.
Qhov hla ntu ntawm qhov deceleration ridge tsev nyob rau hauv qhov dav thiab qhov siab cov lus qhia yuav tsum yog kwv yees li trapezoidal lossis arc-puab. Qhov dav loj yuav tsum nyob hauv thaj tsam ntawm (300mm ± 5mm) ~ (400mm ± 5mm), thiab qhov siab loj yuav tsum nyob rau hauv thaj tsam ntawm (25mm ± 2mm)-(70mm ± 2mm). Qhov piv ntawm qhov dav rau qhov loj yuav tsum tsis txhob ntau tshaj 0.7.
Qhov zoo tshaj plaws roj hmab-yas ceev pob yuav tsum xyuas kom meej tias lub tsheb yuav tsis khiav tawm ntawm kev tswj thaum hla, thiab cov khoom tseem ceeb ntawm kev nyab xeeb yuav tsis puas. Nws yuav tsum muaj kev nyab xeeb ntawm kev tsav tsheb siab thiab kev nyab xeeb ntawm cov qauv.
