Tsab xov xwm no piav qhia txog qhov sib piv ntawm kev txiav zoo tshaj plaws, cov mis xam, cov yam cuam tshuam thiab cov yam ntxwv tseem ceeb ntawm kev ua haujlwm rau kev txiav cov xov hlau tam sim no, uas tuaj yeem siv tau tam sim ntawd.
I. Compression Ratio yog dab tsi? Nkag siab nws lub ntsiab lus tseem ceeb ua ntej
Qhov piv ntawm kev sib zog (tseem hu ua tus nqi sib zog lossis tus nqi sib zog) ntsuas qhov sib piv hloov pauv ntawm thaj chaw hla ntawm tus neeg xyuas pib ua ntej thiab tom qab crimping, uas qhia txog qhov nruj ntawm cov neeg xyuas pib thiab cov davhlau ya nyob twg. Muaj ob txoj kev xam zauv tseem ceeb hauv kev lag luam.
USCAR-21 (Feem ntau siv rau hauv kev tsim tsheb thiab kev siv hluav taws xob, qhov nrawm ntawm kev nias)
Qhov Sib Npaug Sib Npaug (%) = 100 × (1 - Thaj tsam hla ntawm tus neeg coj tom qab crimping / Thaj tsam hla ntawm tus neeg coj ua ntej crimping)
Piv txwv li: Ib tug neeg hlau 50mm² ua ntej crimping muaj nws thaj tsam hla-sectional txo los ntawm 20% tom qab crimping, nrog rau qhov sib piv compression ntawm 20%.
VW 60330 (Siv dav hauv cov qauv German thiab cov teb kev lag luam, qhov sib piv compaction)
Qhov Sib Npaug Sib Npaug (%) = Thaj tsam hla ntawm tus neeg coj tom qab crimping / Thaj tsam hla ntawm tus neeg coj ua ntej crimping × 100%
Piv txwv li: Yog tias thaj chaw tus neeg coj tom qab crimp suav txog 80% ntawm thaj chaw qub, qhov piv ntawm kev nias yog 80%.
