Txuam cov khoom hom thiab kev co txo kev ua tau zoo ntawm cov ntaub qhwv
Dab tsi yog cov khoom siv nquag hom ntawm - rail pads? Lawv cov cwj pwm txo tau li cas?
Cov khoom siv nquag ntawm {{0} {railing roj hmab, siab}}}}}}}}}}} pa ntaub. Cov roj hmab zoo tib yam muaj tus nqi qis, ib qho damping coeffiting ntawm 0.2}} txoj kab kev tsheb ciav hlau ceev, thiab lwm cov kev sib tw nrog kev co kev co kom txo qis. Siab - damping roj hmab cov ntaub qhwv muaj txiaj ntsig, thiab tuaj yeem txo cov nyhuv coeffitay, thiab muaj peev xwm txo qis kev tsheb ciav hlau, thiab lwm txoj kab nrog kev co kom txo qis. POLYURETHANE PADS muaj cov kev coj ua muaj zog thiab kev tiv thaiv zoo, haum cov nyhuv coeffiting thiab hnyav kev tsheb ciav hlau thiab cov ntug dej hiav txwv. Fiber ntau txhawb cov pa hluav taws xob yog lub teeb ci ntsa iab thiab muaj cov kev ua kom zoo, haum rau kev tsheb nqaj hlau, subways, thiab lwm yam kev xav tau lub teeb yuag thiab rwb thaiv tsev. Cov ntaub qhwv ntoo muaj elasticity zoo tab sis yuav tsum muaj kev lwj siab, haum rau cov kab kev ib ntus thiab cov dame kev ua haujlwm, nrog damping coefficient ntawm 0.2-0.3. Qhov kev co txo cov kab mob ntawm cov khoom sib txawv ntawm cov khoom sib txawv, thiab lawv yuav tsum tau xaiv raws li kab kev co kom txo qis.
Dab tsi yog qhov tshwj xeeb yuav tsum muaj kev txo qis kev ua tau zoo ntawm {{0} {rail pads hauv high {1} ceev ceev cov kab tsheb ciav hlau? Yuav ua li cas ntsib lawv?
High - Ceev cov kab kev tsheb ciav hlau muaj ntau dua lossis sib npaug}}} Rail railing coefficient kom muaj ntau dua los yog sib npaug rau 0.15 kom ntseeg tau tias kev thauj khoom zoo tshaj. Txhawm rau ua kom tau raws li qhov yuav tsum tau ua, siab- Damping roj hmab lossis cov khoom siv polyurethane yuav tsum tau xaiv, uas tuaj yeem ua kom muaj zog {}} zaus kev co hluav taws xob. Lub qub tawv ntawm cov ncoo yuav tsum tau tswj hwm ntawm 55-}} kev siv zog ua kom tiav kom ua tiav kev co kom txo tau. Lub thickness ntawm lub ncoo yog tsim los ua 10-15 hli, thicker tshaj li cov ntaub qhwv zoo tib yam, nce qhov chaw deformation thiab txhim kho cov nyhuv reformitation. Thaum lub sij hawm tsim kev tsim khoom, muab cov carbon thiab silica tau ntxiv rau cov qauv zoo thiab txhim kho cov coeffing uas dame thiab kev ruaj khov. Nquag xyuas qhov kev ua kom txo qis ntawm lub ncoo thiab hloov nws kom tsis txhob muaj kev cuam tshuam ntawm kev ua haujlwm ntawm kev tsheb ciav hlau siab.
Vim li cas nyob rau hauv - rail pads rau hnyav {1} {{2 {2 2}} bearing muaj peev xwm? Yuav ua li cas kom ua tiav nws?
Hnyav - Haul Lines muaj loj tsheb ciav hlau qov tsheb, thiab lub ncoo yuav tsum tau ris siab loj. Nyob rau tib lub sijhawm, qhov kev co thaum lub tsheb ciav hlau dhau yog qhov loj, yog li ua tau kev co kom tsis txhob muaj kev puas tsuaj rau txoj kev puas tsuaj. Yog hais tias tsuas yog tsom rau load - Cov nyhav muaj peev xwm loj heev, uas yuav ua rau lub log tsis zoo, uas yuav ua rau muaj kev phom sij. Yog tias tsuas yog tsom rau kev co txo qis, lub pob tsuas yog me me, uas yuav ua rau taug qab deformation thiab cuam tshuam kev nyab xeeb. Yuav kom ua tiav qhov sib npaug ntawm ob, siab- lub zog thiab siab} modulethane thiab siab}} oldulethane thiab siab}} bearration. Cov ntaub qhwv tau txais txheej txheej txheej txheem txheej txheem txheej txheej txheej txheem: cov txheej txheej sab saud yog qhov siab txheej yog qhov siab-}}}} cov kabmob txheej, txhua qhov ua nws tus kheej haujlwm. Txhim kho cov txheej txheem tsim qauv ntawm cov ntaub qhwv, saws honeycomb lossis ribbed qauv los txhim kho cov nyhuv kev co kom meej thaum ua rau muaj zog. Tswj cov nqi zaws ntawm 5% -10% kom paub meej tias tsis muaj kev txwv ntau yam nyob rau hauv kev thauj khoom thiab ua tau raws li kev co kom txo cov kev txwv.
Dab tsi yog qhov sib txawv hauv cov khoom xaiv ntawm hauv qab - rail taab hauv cov chaw sib txawv?
Cov chaw maj ntug av yuav tsum xaiv cov ntaub ntawv nrog cov khoom siv roj hmab muaj zog, kom tsis txhob muaj kev ua kom muaj zog ntawm cov khoom siv roj hmab zoo nkauj, nrog kev pabcuam lub neej ntawm 8- 10 xyoo. Alpine thaj tsam xav tau xaiv tsawg- cov khoom siv kub tsis zoo, xws li tsis muaj qhov sib luag ntawm cov roj hmab uas tau hloov kho tshiab ntau dua lossis sib npaug ntawm 85%. Cov cheeb tsam kub yuav tsum xaiv kev laus- tiv taus thiab siab {13} qhov kev ua kom haum fluoruber tau hloov kho kom zoo dua 10%. Qhov chaw nyob hauv av yog av noo thiab noo noo-pov thawj yuav tsum tau xaiv, kom tsis txhob muaj pwm los ntawm kev ua tau zoo. Qhuav nyob rau hauv thaj chaw muaj qis dua cov ntaub ntawv, thiab roj hmab siv roj hmab lossis cov ntaub qhwv fiber ntau cov ntaub qhwv tau xaiv los tswj cov nqi, nrog kev txij nkawm ntawm 5-6 xyoo.
Yuav ua li cas phim cov tuab tuab thiab txhav ntawm hauv qab - rail pad nrog kev tsheb nqaj hlau?
Teeb kev tsheb ciav hlau (8 {{}} 30kg / m)}}}}}}}}}}} Nruab Nrab Rail (30 - 50 thiab p50} {} {} {}}}}}}}}} {}. Cov tsheb ciav hlau hnyav (50-75kg / m) xws li 605kg / m, modulus roj hmab pawm ntawm 70-90kn / mm los xyuas kom meej lo load-muaj hwj huam muaj peev xwm. Txawv teb chaws txheem hnyav-hau ciav hlau xws li Uic60 thiab 136re hloov kho thiab muaj zog ntawm 15-100km / hli kom tau raws li cov kev cai hnyav thiab kev co. Lub thickness thiab txhav ntawm lub ncoo yuav tsum tau nce nrog kev nce ntawm tsheb ciav hlau kom ntseeg tau tias kev yoog raws thiab zam kev tawm tsam lossis kev sib tw tsis txaus.
