Kev sib tw nruj thiab taug qab kev vibration txo kev ua tau zoo ntawm Rail Pads
Dab tsi yog qhov tseem ceeb ntawm txoj kev tsheb ciav hlau?
Rail pads feem ntau ua haujlwm kom txo qis kev vibration, tsis, thiab qib kev khiav. Lawv nqus lub log-rail cuam tshuam lub zog, txo qhov kev sib kis ntawm kev co mus rau cov neeg pw tsaug zog thiab lub txaj taug kev, thiab kho qhov kev nruj kom ua kom zoo dua lub log -rail kev nyuaj siab faib tawm, ua kom txoj kev taug kev du thiab ruaj khov.
Yuav ua li cas yuav tsum tau qhov nruj ntawm cov rail pads yuav tsum tau ua raws li cov kev cai ntawm kev khiav hauj lwm cov kab?
Siab- cov kab ceev yuav tsum muaj qhov nruab nrab- nruj rail pads kom sib npaug txo kev co thiab ruaj khov; hnyav- cov kab thauj khoom siv siab - nruj, siab - compression - lub zog tsheb ciav hlau kom tiv taus cov khoom hnyav; thiab subway vibration-damping seem siv qis-stiffness, siab-damping rail pads kom txo tau qhov cuam tshuam ntawm kev co thiab suab nrov ntawm ib puag ncig ib puag ncig.
Cov teeb meem taug qab dab tsi tshwm sim los ntawm kev laus thiab deformation ntawm cov tsheb ciav hlau?
Kev laus ntawm cov ntaub thaiv kev tsheb ciav hlau ua rau muaj kev hloov hauv qhov tawv nqaij, ntau dhau compressive mus tas li deformation, poob ntawm kev vibration txo cov nyhuv, thiab nce lub log -rail cuam tshuam. Qhov no, nyob rau hauv lem, accelerates rail hnav, loosens fasteners, thiab ua rau cov tsheb ciav hlau tsis sib xws, cuam tshuam loj heev rau tsheb ciav hlau stability thiab kev pab cuam lub neej ntawm khiav cov khoom.
Dab tsi yog qhov cuam tshuam ntawm cov khoom siv tsheb ciav hlau (rubber, polyurethane) ntawm kev ua haujlwm?
Roj hmab taug kev pads muab zoo elasticity thiab tus nqi qis, ua rau lawv haum rau cov pa ceev kab; polyurethane khiav pads khav theeb zoo heev compressive zog thiab creep tsis kam, ua rau lawv haum rau siab -ceev, hnyav- load kab. Cov khoom siv ntawm ob qho tib si txiav txim siab lawv cov kev vibration txo cov nyhuv thiab kev pab lub neej ntawm cov kab sib txawv.
Yuav ua li cas txhawm rau txhim kho qhov sib txuam nruj thiab kev vibration txo kev ua haujlwm ntawm cov ntaub qhwv?
Xaiv cov ntaub qhwv nrog cov ntaub ntawv tsim nyog raws li qib kab thiab kev khiav hauj lwm ceev, optimizing lub ncoo thickness thiab hardness; xyuas kom cov ntaub qhwv nyob hauv nruab nrab thiab tsis muaj eccentric siab thaum nruab; Tam sim ntawd hloov cov laus los yog deformed pads thaum lub sij hawm txij nkawm los xyuas kom meej cov kev vibration txo thiab structural stability.
