Kev sib raug zoo ntawm cov khoom xaiv ntawm lub underrail ncoo phaj nrog kev co thiab suab nrov txo ntawm txoj kab
Dab tsi yog qhov zoo ntawm cov khoom siv roj hmab hauv cov khoom siv hluav taws xob zoo tib yam?
Rubber pads muaj elasticity zoo thiab tus nqi qis. Lawv tuaj yeem nqus tau qhov cuam tshuam ntawm lub log thiab cov ntsia hlau, txo kev vibration thiab suab nrov. Nws muaj zog adaptability thiab muaj peev xwm ua tau raws li qhov kev xav tau ntawm kev vibration txo ntawm lub hauv paus rau cov pa railways thiab nroog railway. Nws yog hom ntaub ntawv uas siv ntau tshaj plaws.
Vim li cas polyurethane pads haum rau siab - cov kab ceev?
Polyurethane pads muaj qhov ruaj khov elastic modulus, tiv taus kev laus thiab hnav, thiab tsis yooj yim rau deformation nyob rau hauv siab -ceev thiab siab - zaus loads. Nws qhov kev vibration damping kev ua tau zoo yog qhov ntev - kav ntev, uas tuaj yeem tswj tau qhov du ntawm txoj kev mus ntev thiab txo qhov cuam tshuam kev puas tsuaj rau cov fasteners thiab cov ntsia hlau.
Yuav ua li cas yog cov yam ntxwv ntawm daim ntawv thov ntawm composite pads nyob rau hauv complex ib puag ncig?
Cov ntaub ntawv sib xyaw ua ke ua ke cov khoom zoo ntawm cov roj hmab thiab cov ntaub ntawv polymer, uas muaj ob qho tib si elasticity thiab siab zog. Hauv cov txheej txheem rhiab heev xws li Choj thiab qhov av, nws tuaj yeem txo qis kev sib kis tau zoo thiab tiv thaiv cov tsev thiab khoom siv raws kab.
Dab tsi cuam tshuam qhov kev laus ntawm cov ntaub qhwv ntsej muaj rau ntawm txoj kev?
Kev laus tuaj yeem ua rau cov ntaub qhwv tawv tawv, tawg thiab poob elasticity, ua rau muaj kev poob qis hauv kev vibration damping. Qhov no yuav ua rau lub log hnyav dua - kev tsheb nqaj hlau cuam tshuam, ua kom lub zog ntawm cov fasteners thiab kev puas tsuaj ntawm cov neeg pw tsaug zog, thiab ua rau cov nqi tu thiab kev nyab xeeb ntawm cov kab.
Yuav ua li cas xaiv cov ntaub qhwv kom tsim nyog raws li hom kab?
Tsawg modulus roj hmab ncoo yuav tsum tau xaiv rau cov cheeb tsam hauv nroog. Polyurethane composite pads raug xaiv rau siab - txoj kev siab ceev. Rau qhov hnyav- cov kab ua haujlwm, xaiv siab - hnav- cov ntaub qhwv cov ntaub qhwv. Cov dej noo- pov thawj thiab tiv thaiv- cov khoom siv corrosion raug xaiv rau lub qhov av, suav nrog kev txo qis kev co thiab kev pabcuam lub neej.
