Rail pad cov khoom siv thiab cov nyhuv taub hau
- Dab tsi yog cov khoom siv rau hauv qab - rail pads? Lawv tus cwj pwm Cushioning yog dab tsi?
Cov ntaub ntawv uas muaj cov roj hmab muaj xws li roj hmab zoo nkauj, uas muaj cov tsheb ciav hlau kev ua kom zoo, thiab muaj peev xwm siab} Kev kub ceev thiab kev laus tsis kam. Styrene - butadiene roj hmab tau qis dua tus nqi qis dua, thiab txhim kho cov roj hmab tsis kam, feem ntau siv hauv kev tsheb nqaj hlau. Chloroprene roj hmab muaj huab cua zoo thiab hnav tsis kam, ruaj khov lub zog ua kom muaj zog, thiab haum rau cov av noo thiab hmoov av. Ib qho ntxiv, cov khoom siv polyurethane muaj cov hardness, muaj zog bearing muaj peev xwm thiab ntev} ntev {{6} haul railways.
- Dab tsi uas cuam tshuam ua lub hardness ntawm cov khoom muaj nyob rau ntawm lub cushioning nyhuv ntawm {{}} rail pads?
Cov nyhuv cushioning yog qhov zoo tshaj plaws thaum cov khoom siv tawv tawv yog qhov nruab nrab. Piv txwv li, roj hmab cov ntaub qhwv nrog ntug dej hardness ntawm 60 - 70}}}}}}}}} kev puas tsuaj thaum muaj kev cuam tshuam me me thaum muaj kev cuam tshuam lub zog. Yog tias lub hardness dhau lawm (tshaj li 75 degrees), lub ncoo muaj peev xwm ua kom muaj peev xwm ua kom muaj peev xwm sib kis tau ncaj qha rau tus neeg pw tsaug zog, kev sib txawv ntawm cov kev hnav ris tsho. Yog tias lub hardness yog tsawg dhau (hauv qab 55 degrees), ua rau kev tsheb ciav hlau ntau dhau, cuam tshuam txoj kev smoothness, thiab ua kom luv lub neej pabcuam ntawm lub ncoo.
- Dab tsi yog qhov sib txawv ntawm cov kev yuav tsum tau rau cov cushioning nyhuv ntawm - rail taab hom?
Siab - Ceev railwations xav tau ntau dua 30% los xyuas kom muaj roj hmab kom txaus siab, thiab muaj roj hmab siab yog feem ntau siv. Hnyav - haul railways ua tau kom muaj kev sib luag hauv cov roj hmab loj hlob hauv qab ntawm {}}℃feem ntau tau raug xaiv. Nroog Rail Transit muaj lub siab yuav txo cov suab nrov thiab lub zog nqus cov pa taws, thiab cov ntaub qhwv cov ntaub roj hmab feem ntau siv.
- Yuav sim ntsuas lub zog cushioning ntawm hauv - rail pads?
Dynamic compression kuaj muaj peev xwm nqa tawm mus rau simulate lub tsheb ciav hlau thauj mus rau hauv ncoo, ntsuas qhov deformation thiab rov qab ceev ntawm lub ncoo. Cov uas muaj kev sib cais los thiab rov ua kom nrawm dua muaj cov nyhuv zoo. Los ntawm kev xeem xeem, nruab hauv ncoo rau ntawm txoj kev sim thiab ntsuas qhov kev co amplitude thaum lub tsheb ciav hlau dhau mus. Qhov ntau qhov ntau dua ntxiv, qhov zoo dua cov txiaj ntsig cushioning. Lub zog dynamic {{{{}} Lub cev tawv tawv tawv tawv sib zog ntawm cov ntaub qhwv tau kuj tseem raug kuaj. Tus me dua ntawm cov sib piv, qhov ntau ruaj khov lub cushioning kev ua tau zoo, thiab feem ntau cov piv txwv yuav tsum tsis pub tshaj 1.5.
- Cov teeb meem ib puag ncig cuam tshuam li cas rau kev ua haujlwm cushioning ntawm - rail pads?
High -} Ib puag ncig yuav tsum so cov hnab roj hmab, txo nws lub hardness, thiab ua kom lub zog ua kom yuam kev tsis ruaj khov. Nyob rau hauv high - sov cov cheeb tsam, siab- cov khoom siv kub tsis kam raug xaiv. Tsawg -} pa taws ib puag ncig yuav ua rau cov roj hmab kom tawv, txo qis elasticity, thiab txo qis cov txiaj ntsig cushioning. Hauv thaj chaw txias, qis {{{{{{}} cov roj hmab kub tiv taus roj hmab yuav tsum tau xaiv. Kev ua ib puag ncig tej zaum yuav ua rau lub ncoo nqus dej thiab nthuav, cuam tshuam kev ruaj khov, thiab txo cov txiaj ntsig cushionion. Nws yog ib qho tsim nyog los xaiv cov ntaub ntawv nrog kev ua haujlwm tsis zoo, xws li tshuaj roj hmab vloroprene.
