Cov yam ntxwv uas txiav txim siab Pad Elasticity
Khoom siv yog qhov tseem ceeb. Rubber pads muaj elasticity zoo thiab zoo nqus kev co; ntuj roj hmab pads feem ntau muab elasticity zoo dua li hluavtaws roj hmab. Cov ntaub qhwv yas muaj qhov elasticity tsis zoo, tab sis lawv qhov kev ua tau zoo yog ruaj khov nyob rau hauv cov khoom tshwj xeeb. Thickness thiab hardness kuj tseem ceeb: nyob rau hauv tib cov ntaub ntawv, cov ntaub ntawv tuab yog elastic dua, yog li 10 hli roj hmab ncoo outperforms ib 6 hli ncoo ntawm tib lub compound. Pads nrog cov hardness me ntsis qhia qhov zoo tshaj plaws elastic kev ua tau zoo; hardness uas siab dhau ua rau lub ncoo txhav thiab inelastic, thaum hardness uas tsawg dhau ua rau ntau deformation. Internal qauv yog tus thib peb qib: foamed roj hmab pads thiab pads nrog hollow designs muaj zoo elasticity thiab poob siab absorbing ua tsaug rau lawv cov huab cua nyob rau hauv cov qauv, thiab yog haum rau cov kab uas muaj kev poob siab absorbing.
Daim ntawv thov ntau yam los ntawm Elastic Modulus
High-elasticity pads nrog elastic modulus ntawm 20-50 MPa yog haum rau kev tsheb ciav hlau hauv nroog thiab siab - kev tsheb ciav hlau ceev, qhov uas lawv txo qis kev co thiab suab nrov thiab txhim kho kev caij tsheb. Nruab nrab- elasticity pads nrog ib tug modulus ntawm 50-100 MPa yog siv nyob rau hauv tib lub cev railways, ntsuas qhov poob siab absorbing tiv thaiv kev ruaj ntseg rau kev khiav hauj lwm. Tsawg- elasticity pads nrog ib tug modulus siab tshaj 100 MPa yog siv rau hnyav - tsheb ciav hlau railways: lawv rigidity nqa siab loads, txo txoj kev deformation thiab xyuas kom meej cov kab stability. Nyob rau hauv cov xwm txheej tshwj xeeb xws li metro curves, high-elasticity pads yuav tsum tau ua ke nrog cov khoom siv los tiv thaiv kom tsis txhob muaj kev vibration tsis pub txoj kev tsheb ciav hlau nkag mus ntev.
Installation yuam kev thiab lawv cov txim
Misalignment ntawm lub ncoo thaum lub sij hawm installation ua rau tsis sib xws kev ntxhov siab, thiab lub zos elasticity ntawm lub ncoo yuav tsum tau exerted, ua rau muaj zog khiav kev co. Piv txwv li, yog hais tias lub ncoo offset tshaj 5 hli, qhov elastic kev ua tau zoo txo los ntawm ntau tshaj 30%. Qhov khoob lossis sib tshooj ntawm cov ntaub qhwv uas nyob ib sab kuj ua rau kev sib kis tsis sib xws: lub ncoo ntawm qhov sib txawv yuav siv sij hawm ntau dhau thiab nws cov elasticity decays sai, thaum qhov sib tshooj yog tuab heev thiab cuam tshuam rau kev ruaj ntseg. Kev ua tsis tiav ntawm kev ntxuav cov khib nyiab xws li pob zeb thiab av los ntawm lub txaj hauv ncoo ua rau lub zog hauv zos ntau dhau, cov yas deformation ntawm lub ncoo, tsis muaj elasticity mus tas li thiab lub neej ua haujlwm luv. Kev txhim kho zoo yog li ncaj qha txiav txim siab seb qhov kev tsim kho tau ua tiav.
Kev kuaj thiab lees txais Elastic Performance
Elasticity raug kuaj nrog lub tshuab ntsuas siab: siv lub nra hnyav xws li 10 kN, ntsuas qhov compression thiab rebound ntawm lub ncoo, thiab lees txais lub ncoo thaum tus nqi rov qab yog tsawg kawg 90%. Kev kuaj qaug zog simulates lub tsheb ciav hlau thauj khoom: tom qab 1 lab lub voj voog, qhov elastic attenuation tus nqi yuav tsum tsis pub tshaj 15%. Nyob rau ntawm qhov chaw, lub ntsuas kev vibration ntsuas qhov kev vibration: qhov kev vibration acceleration ntawm ib qho kev txhim kho siab -elasticity ncoo yuav tsum tau txo los ntawm ntau tshaj 30% piv nrog cov khiav tsis muaj lub ncoo. Cov tsos mob thiab kev kuaj xyuas me me yuav tsum tsis muaj qhov tawg lossis deformation thiab qhov sib txawv ntawm thickness tsis ntau tshaj 1 hli, uas ua kom ruaj khov elastic kev ua tau zoo thoob plaws hauv cov khoom.
Kev Laus Cwj Pwm thiab Kev Hloov Ua Kom Zoo
Tom qab siv sij hawm ntev -, ncoo elasticity poob vim cov khoom aging. Cov ntaub qhwv roj hmab raug tshav ntuj thiab kub siab tuaj yeem poob 20-30% ntawm lawv elasticity hauv 3-5 xyoos. Kev ua haujlwm tsis tu ncua ua rau qaug zog ntawm cov khoom siv hauv ncoo, ua rau lub zog compression thiab rov muaj peev xwm; Piv txwv li, qhov elastic attenuation tus nqi ntawm cov ntaub qhwv ntawm cov tsheb ciav hlau hnyav tuaj yeem ncav cuag 25% tom qab 5 xyoos. Ib puag ncig yam xws li roj paug thiab tshuaj lom neeg corrosion ua rau cov khoom siv hauv ncoo thiab ua kom qhov poob qis; roj hmab pads nyob rau hauv kev sib cuag nrog cov roj poob elasticity sai dua thiab yuav harden thiab tawg. Kev hloov pauv yog vim li no los ntawm kev ntsuas qhov tawv nqaij hloov pauv thiab pom kev puas tsuaj, tsis yog nyob rau lub sijhawm ruaj khov ib leeg: cov ntaub qhwv yuav tsum tau hloov thaum qhov hloov pauv qhov tawv nqaij zoo li qub lossis cov txheej txheem compression tshaj qhov kev lees paub txwv tau teev tseg rau lub kaw lus fastening.
Cov lus nug nquag
Q1: Yam dab tsi cuam tshuam rau kev ua haujlwm elastic ntawm cov ntaub thaiv kev tsheb nqaj hlau?
Khoom hom, thickness, hardness thiab internal qauv. Roj hmab yog elastic dua li cov yas, cov ntaub qhwv tuab dua yog elastic, nruab nrab hardness ua tau zoo tshaj plaws, thiab cov qauv foamed los yog hollow ntxiv kev poob siab.
Q2: Lub ncoo twg haum rau kev siab - kev tsheb ciav hlau ceev?
High- elasticity pads nrog elastic modulus ntawm 20-50 MPa, uas ua rau kom muaj kev vibration thiab suab nrov txo thiab caij tsheb. Nruab nrab modulus ncoo ntawm 50-100 MPa nplua kab kab.
Q3: Yuav ua li cas yog hais tias lub ncoo ntsia misaligned?
Kev ntxhov siab tsis sib xws txo cov elasticity zoo: qhov kev sib txawv ntawm ntau dua 5 hli txiav elastic kev ua tau zoo los ntawm ntau dua 30%, thiab qhov khoob lossis sib tshooj cuam tshuam txoj kev thauj khoom.
Q4: Cov ntaub qhwv elasticity kuaj tau li cas?
Nrog rau lub tshuab ntsuas siab nyob rau hauv ib qho kev thauj khoom xws li 10 kN, xyuas tias qhov rov ua haujlwm yog tsawg kawg 90%; ib qho kev sim qaug zog tshaj 1 lab lub voj voog yuav tsum muaj qhov txo qis qis dua 15%; ntawm -qhov chaw vibration yuav tsum raug txo kom ntau dua 30%.
Q5: Yuav ua li cas sai li sai tau pads poob elasticity?
Roj hmab ncoo nyob rau hauv tshav ntuj thiab kub kub yuav poob 20-30% elasticity nyob rau hauv 3-5 xyoo, thiab hnyav-haul kab ntaub yuav qhia 25% attenuation tom qab 5 xyoo. Roj thiab tshuaj lom neeg sib cuag accelerates qhov poob.
