Dab tsi yog cov cuab yeej cuab tam ntawm Profile S20 rail?
Mechanical Properties ntawm lubProfile S20 lub teeb rail(DIN 5901) nyob ntawm tag nrho cov qib steel xaiv rau ntau lawm. Nws yog feem ntau tsim nyob rau hauv ob qib sib txawv steel:55Q (Medium-Carbon) rau active dov hnav thiabQ235B (Tsawg-Carbon) rau lub teeb- lub luag haujlwm lossis cov qauv tsim.
1. Mechanical Properties Matrix
| Mechanical Property | 55Q Steel Qib (Standard / Hnav-Resistant) | Q235B Steel Qib (Nqis -Txoj haujlwm / Weldable) |
| Tensile zog | Ntau dua lossis sib npaug li 685 MPa | 375-460 MPa |
| Yield zog | Ntau dua lossis sib npaug li 390 MPa | Ntau dua lossis sib npaug li 235 MPa |
| Elongation | Ntau dua lossis sib npaug li 14% | Ntau dua lossis sib npaug li 26% |
| Brinell Hardness (HBW) | 200-260 HWB | ~ 140 HWB |
2. Sectional Structural Performance (Geometric Strengths)
Ntxiv nrog rau cov khoom siv raw txwv, lub cev zoo li S20 profile muab cov ntoo khaub lig tshwj xeeb -sectional zog los tiv thaiv ntsug dabtsi yog khoov thiab lateral twisting nyob rau hauv load:
| Theoretical Nyhav | 19.8 kg/m (39.91 lb/yd) |
| Hla -Sectional Area (A/S) | 25.26 cm² (3.92 in²) |
| Lub sijhawm ntawm Inertia (Ix) | 346 cm⁴ (8.31 nyob rau hauv⁴) |
| Ntu Modulus (W) - Base / Rail Foot | 66.8 cm³ (4.08 nyob rau hauv³) |
| Ntu Modulus (W) - Rail Head | 66.8 cm³ (4.08 nyob rau hauv³) |
3. Engineering Performance
- AnalysisLoad-Bearing Threshold:Thaum dov nrog55Q steel, S20 profile yam xyuam xim tuav lub log loads txog 35 txog 45 kN (3.5 txog 4.5 metric tons ib lub log). CovQ235B qib yuav tsum raug txwv kom qis dua, zoo li qub, lossis tsis yog - log tsheb tseem ceeb.
- Fatigue vs. Elasticity:Cov55Q qib muab lub zog tensile siab (Ntau dua lossis sib npaug ntawm 685 MPa) yuav tsum tau los tiv thaiv micro- tawg tawm raws li 10 hli lub vev xaib nyob rau hauv siab - zaus cycling.Q235B muaj superior elongation (Ntau dua los yog sib npaug rau 26%), uas txhais tau hais tias nws muab siab ductility thiab cuam tshuam cushioning tab sis yog raug rau cov yas deformation (mushrooming) nyob rau hauv kev nyuaj siab.
Yuav ua li cas cov tawm los thiab tensile zog ntawm S20 Steel Track Rail tiv thaiv kev khiav mus tas li?
Cov txiaj ntsig thiab tensile lub zog ntawm 55Q steel ua rau S20 rail zoo sib xws thiab tiv thaiv kev puas tsuaj mus tas li los ntawm ob lub tswv yim:
- Yield Strength (Ntau dua lossis sib npaug ntawm 390 MPa) tiv thaiv sagging thiab flattening:Nws tso cai rau nqaim 44 mm rail lub taub hau ua zoo li lub caij nplooj ntoos hlav. Thaum lub log hnyav dhau mus, lub tsheb ciav hlau flexes micro-fractionally thiab snaps rov qab rau hauv qhov chaw. Yog tsis muaj zog txaus, lub taub hau tsheb ciav hlau mus tas li flattens tawm (nceb) thiab sags ntawm kev txhawb nqa.
- Tensile Strength (Ntau dua lossis sib npaug ntawm 685 MPa) tiv thaiv kev sib tw thiab tawg:Thaum lub crane nres lossis tig, lub log flanges thawb nyuaj rau sab ntawm txoj kev tsheb ciav hlau. Lub zog tensile siab nres qhov nyias 10 hli lub vev xaib los ntawm kev sib tw rau sab lossis tawg ntawm lub hauv paus, ua kom lub ntsuas ntsuas zoo sib xws.
Nyob rau hauv luv luv: High yield zog nres lub tsheb ciav hlau los ntawm khoov down, thaum lub zog tensile siab nres nws ntawm twisting tawm.
FAQ
- Dab tsi yog qhov txawv ntawm lub zog tensile thiab lub zog tawm los rau S20 steel rail?
Lub zog tensile ntsuas qhov siab tshaj plaws ntawm S20 steel rail tuaj yeem ua ntej tawg lossis tawg tag. Lub zog tawm los txhais qhov qis dua qhov twg cov hlau pib deform mus tas li. Rau kev nyab xeeb khiav lag luam, koj qhov siab tshaj plaws suav log loads yuav tsum nyob twj ywm zoo hauv qab ntawm qhov pib lub zog.
- Dab tsi yog qhov txiaj ntsig ntawm kev siv cov khoom sib koom ua ke ntawm DIN rail S20 profile?
Kev siv siab - lub zog sib koom ua ke tsim los ntawm cov qauv hlau sib xyaw ua kom ntseeg tau tias cov tsheb ciav hlau sib koom sib koom ua haujlwm ntsug sib npaug ntawm qhov ntev ntawm kev tsheb nqaj hlau. Qhov kev sib koom ua ke no txwv tsis pub muaj kev cuam tshuam hauv zos khoov los ntawm kev thauj khoom ntau dhau ntawm txoj kev tsheb ciav hlau, txo qhov kev pheej hmoo ntawm bolt - qhov tawg hla koj S20 Railway Steel Rail txoj kev.
