Taug qab Pad Khoom thiab vibration Damping Performance
Dab tsi yog cov yam ntxwv ntawm cov khoom siv feem ntau rau hauv qab - cov phiaj xwm kev tsheb ciav hlau?
Cov roj hmab hauv paus phaj yog cov khoom siv feem ntau, nrog zoo elasticity thiab poob siab absorbing nyhuv, uas muaj peev xwm nqus tau lub tsheb ciav hlau load cuam tshuam thiab txo txoj kev vibration thiab suab nrov. Polyurethane puag daim hlau muaj kev hnav zoo dua thiab kev laus ua haujlwm, thiab lawv lub neej kev pabcuam yog 2-3 npaug ntawm cov roj hmab zoo tib yam, ua rau lawv haum rau hnyav-load lossis siab- zaus siv cov xwm txheej. Cov roj hmab hauv paus phaj muaj cov huab cua tsis muaj zog thiab ua rau tawv tawv lossis tawg hauv qhov chaw kub lossis qis, thaum polyurethane puag daim hlau tuaj yeem hloov mus rau qhov kub ntau ntawm -40℃txog 60℃. Ob qho khoom siv yuav tsum muaj lub zog compressive los xyuas kom meej tias qhov compression deformation mus tas li tsawg dua lossis sib npaug li 3% nyob rau hauv lub sijhawm ntev. Roj Hmab-hlau sib xyaw phaj yog siv nyob rau hauv qee qhov tshwj xeeb scenarios kom sib npaug elasticity thiab cov qauv kev ruaj ntseg.
Dab tsi yog qhov kev sib raug zoo ntawm kev xaiv hardness ntawm hauv qab -rail base plates thiab kab hom?
High- txoj kev tsheb ciav hlau ceev muaj qhov yuav tsum tau ua rau kev poob siab, thiab cov roj hmab hauv paus phaj nrog Shore hardness ntawm 60-70A feem ntau yog xaiv, uas tuaj yeem muab cov txiaj ntsig zoo rau kev poob siab thaum ua kom muaj peev xwm thauj khoom -cov kabmob. Cov kev tsheb ciav hlau ceev ceev muaj cov khoom me me, thiab cov phaj hauv lub hauv paus nrog hardness ntawm 70-80A tuaj yeem raug xaiv kom sib npaug ntawm qhov nqus thiab tus nqi. Hnyav- txoj kev tsheb ciav hlau yuav tsum tau ua qhov tseem ceeb ntawm kev thauj khoom- cov kabmob muaj peev xwm, thiab lub hauv paus phaj hardness yuav tsum ncav cuag 80-90A kom tsis txhob muaj kev sib tsoo ntau dhau. Kev tsheb ciav hlau hauv nroog nyob ze rau thaj chaw nyob thiab muaj cov kev xav tau siab rau kev tswj lub suab nrov, yog li cov phaj qis qis ntawm 60-65A feem ntau yog siv los txhim kho kev poob siab thiab txo cov suab nrov. Qhov chaw tig tawm yog raug rau cov quab yuam nyuaj, yog li cov phaj siab elasticity nrog hardness ntawm 75-85A yuav tsum tau xaiv kom haum rau kev cuam tshuam ntau zaus.
Yam dab tsi cuam tshuam rau kev ua haujlwm ntawm kev poob siab ntawm hauv qab -rail base plates?
Lub elastic modulus ntawm cov khoom yog cov tseem ceeb influencing yam; qhov qis dua elastic modulus, qhov zoo dua qhov kev poob siab absorbing nyhuv, tab sis lub load - bearing peev yuav tsum sib npaug. Lub thickness tsim ntawm lub hauv paus phaj yuav tsum tau raws li cov kab kev poob siab absorbing yuav tsum tau; feem ntau, lub thickness ntawm siab - ceev railway puag daim hlau yog 12-15 hli, thiab cov pa ceev railways yog 8-12 hli. Lub ambient kub yuav cuam tshuam cov khoom elasticity; Kev kub siab heev lossis qis qis yuav txo qhov kev poob siab ntawm kev ua haujlwm, thiab cov khoom tsim nyog rau qhov ntsuas kub yuav tsum raug xaiv. Qhov ceev uniformity ntawm lub hauv paus phaj kuj tseem ceeb heev; qhov tsis sib xws yuav ua rau lub zog tsis sib npaug thiab txo qhov kev poob siab hauv zos. Kev laus thiab hnav tom qab siv mus ntev yuav ua rau elastic attenuation, thiab kev ua haujlwm poob siab yuav maj mam txo, yuav tsum tau hloov tsis tu ncua.
Cov kev cai tshwj xeeb dab tsi ua hnyav - txoj kev tsheb ciav hlau muaj rau hauv qab - daim phiaj tsheb ciav hlau?
Nyob rau hauv -rail puag daim hlau rau hnyav- txoj kev tsheb ciav hlau yuav tsum muaj zog dua compressive, nrog lub zog compressive ntau dua lossis sib npaug li 15MPa nyob rau hauv qhov ntsuas load los tiv thaiv lub hauv paus phaj puas nyob rau hauv siab. Lub hauv paus phaj yuav tsum muaj kev hnav zoo heev, nrog rau Akron abrasion tus nqi tsawg dua lossis sib npaug li 0.15cm³ / 1.61km kom txo cov thickness poob los ntawm kev sib txhuam ntev ntev. Nws yuav tsum muaj kev qaug zog zoo, tsis muaj kab nrib pleb lossis kev puas tsuaj tom qab 2 lab lub voj voog ntawm reciprocating load. Lub hauv paus phaj muaj cov kev xav tau siab dua rau qhov kev ruaj ntseg, nrog qhov ntev thiab qhov dav sib txawv Tsawg dua lossis sib npaug li ± 2 hli thiab thickness sib txawv tsawg dua lossis sib npaug ± 0.5 hli kom nruj haum nrog cov neeg pw tsaug zog. Qee qhov hnyav- cov kab tsheb thauj khoom siv cov phaj tuab tuab (15-20mm tuab) los txhim kho ob qho tib si thauj khoom thiab kev poob siab.
Qhov kev txhim kho zoo li cas hauv qab - cov phiaj xwm kev tsheb nqaj hlau cuam tshuam rau kev siv?
Thaum lub sij hawm installation, lub hauv paus phaj yuav tsum tau txuas tag nrho rau cov pw tsaug zog thiab hauv qab ntawm txoj kev tsheb ciav hlau, tsis muaj curling los yog hollowing, txwv tsis pub nws yuav ua rau lub zog tsis sib xws thiab kev poob siab hauv zos. Qhov saum npoo ntawm lub hauv paus phaj yuav tsum huv si thiab tsis muaj khib nyiab; Yog hais tias impurities xws li xuab zeb nplej yog tov rau hauv, qhov chaw ntawm lub hauv paus phaj yuav puas nyob rau hauv load, shortening cov kev pab cuam lub neej. Kev sib txawv ntawm kev teeb tsa ntau dhau yuav ua rau lub hauv paus phaj hloov mus rau hauv lub zog, ua rau tsis sib xws ntawm ib sab tom qab siv sijhawm ntev - thiab cuam tshuam rau kev sib tw. Qhov ntom ntom ntawm lub hauv paus phaj yuav tsum ua raws li cov lus qhia tshwj xeeb; Txhua tus neeg pw tsaug zog sib raug rau ib lub phaj ua tiav, thiab kev sib txuas yog txwv tsis pub. Tom qab kev teeb tsa, qhov compression npaum li cas ntawm lub hauv paus phaj yuav tsum tau kuaj xyuas kom ntseeg tau tias nws nyob hauv qhov tsim ntau yam, tsis txhob muaj compression ntau lossis tsis txaus compression.
