Nkag siab txog 0.00623 Coefficient hauv Round Bar Ntsuas Ntsuas
Cov qauv siv feem ntau rau kev kwv yees qhov ntsuas theoretical ntawm cov khoom puag ncig yog:
Qhov hnyav (kg / m) = 0.00623 × 6
Qhov coefficient no (0.00623) yog muab los ntawm cov khoom siv ntom ntom thiab qhov chaw hla ntawm qhov bar. Hauv qab no yog cov lus piav qhia ntxaws txog keeb kwm thiab kev siv tus nqi no.
1. General Formula rau Round Bar Nyhav
Qhov yooj yim theoretical hnyav formula yog:
luas (kg/m) = luas-sectional Area × Density = (π / 4 × d²) × ρ
- d: Txoj kab uas hla (mm)
- ρQhov ceev (g / cm³)
Xyuas kom tag nrho cov chav nyob zoo ib yam - thaj tsam hauv mm², qhov ceev hloov mus rau kg / mm³.
2. Derivation Piv txwv rau 304 Stainless Hlau
Qhov ntom ntawm 304 stainless hlau yog kwv yees li:
ρ = 7.93 g/cm³ = 7930 kg/m³
Hloov mus rau hauv cov mis:
Luj (kg/m) = (π / 4) × d² × (7930 / 1,000,000) ≈ 0.006217 × d²
Rounded rau engineering siv:Luas = 0.00623 × d²
Piv txwv li: 904L Stainless Hlau Round Bar Qhov Ntsuas Ntsuas Cov Qauv
Lub theoretical hnyav ib 'meter' ntawm ib tug khoom puag ncig bar ua los ntawm904L stainless hlautuaj yeem suav nrog cov qauv hauv qab no:
Qhov hnyav (kg / m) = (π / 4) × d² × ρ
Qhov twg:
- d= Txoj kab uas hla mus millimeter (mm)
- ρ= Qhov ceev hauv kg/mm³
Qhov ntom ntawm 904L Stainless Hlau:
Luas = 8.00 g/cm³ = 8000 kg/m³ = 8.0 × 10-6kg/mm³
Formula Derivation:
Qhov hnyav (kg / m) = (π / 4) × d² × 8.0 × 10-6× 1000
luas = 0.006283 × d²
Qhov Kawg Simplified Formula:
Qhov hnyav (kg / m) = 0.00628 × d²
(d yog txoj kab uas hla hauv mm)
Piv txwv:
Rau 904L round bar nrog txoj kab uas hla 50mm:
Luas = 0.00628 × 50² = 0.00628 × 250015.70 Kg / m
3. Daim ntawv thov Scope
- Qhov coefficient no haum rau 304/316 stainless hlau lossis txhua yam khoom siv nrog qhov ntom ntom7.93 g/m²
- Cov duab: khoom round bar, pas nrig, ncig billet
- Cov tswv yim: txoj kab uas hla hauv mm, ua rau kg / m
4. Reference Coefficients rau lwm yam ntaub ntawv
