Sib piv cov Elastic Modulus ntawm Rail Pads nrog Track Vibration thiab Noise Reduction Effects
Yuav ua li cas cov modulus ntawm elasticity cuam tshuam qhov kev co txo cov nyhuv ntawm rail bearing pads?
Qhov qis qis ntawm elasticity ua rau cov kabmob softer nrog lub peev xwm deformation ntau dua, kev nqus tau zoo ntawm lub log-rail cuam tshuam lub zog, thiab kev co zoo dua thiab txo suab nrov. Txawm li cas los xij, ib qho kev hloov qis heev tuaj yeem ua rau txoj kev tsheb loj loj, kev ruaj ntseg tsis zoo, thiab cuam tshuam rau lub tsheb ciav hlau khiav smoothness. Ib qho kev ua haujlwm siab dhau los ua rau cov kabmob tsis sib xws, kev sib kis ncaj qha ntawm kev cuam tshuam, txo qis kev co, thiab tseem ceeb kev co thiab suab nrov.
Vim li cas cov modulus ntawm elasticity ntawm rail bearing pads yog ib qho tseem ceeb tshwj xeeb hauv kev tsheb ciav hlau hauv nroog?
Cov kab tsheb ciav hlau hauv nroog feem ntau nyob hauv nroog, yuav tsum muaj kev vibration thiab suab nrov txo kom txo qis kev cuam tshuam rau cov tsev nyob ib puag ncig thiab cov neeg nyob. Tsis tas li ntawd, cov kab tsheb ciav hlau hauv nroog muaj ntau qhov nkhaus, qhov chaw nres tsheb luv luv, thiab nquag braking thiab pib, ua rau txoj kev tsheb ciav hlau nyuaj. Xaiv cov kabmob ncoo nrog qhov tsim nyog modulus yog qhov tseem ceeb rau kev tsim tsheb ciav hlau hauv nroog, vim nws txaus siab rau ob qho tib si txo kev co thiab ua kom muaj kev ruaj ntseg ntawm geometric.
Dab tsi yog qhov sib txawv ntawm cov qauv ntawm elasticity ntawm bearing pads rau siab -ceev thiab pa kab?
High- cov kab ceev yuav tsum tau ua kom du thiab ruaj khov, yuav tsum muaj qhov hloov pauv siab dua rau cov ntaub ntawv taug qab kom ntseeg tau tias muaj kev txhawb nqa kev tsheb ciav hlau txaus thiab tiv thaiv kev sib tw ntau dhau thaum lub sijhawm ua haujlwm siab - tsheb ciav hlau ceev. Cov kab nrawm nrawm muaj qhov yuav tsum tau ua kom qis dua me ntsis, tso cai rau kev siv cov ntaub ntawv taug qab nrog cov qauv qis dua los txhim kho kev co damping thiab txo cov haujlwm ua haujlwm.
Cov teeb meem dab tsi tshwm sim los ntawm qhov tsis tsim nyog modulus ntawm elasticity hauv cov ntaub qhwv?
Modulus siab heev: Ua kom muaj kev vibration thiab suab nrov, ua rau muaj kev puas tsuaj rau cov tsheb ciav hlau, fasteners, thiab cov neeg pw tsaug zog, txhim kho kev ua haujlwm. Modulus tsis txaus: Kev teeb tsa kev tsheb ciav hlau tseem ceeb, teeb meem tswj kev ntsuas kev ntsuas thiab qib, lub tsheb ciav hlau tsis zoo, thiab txawm tias muaj teeb meem xws li xoob cov ntaub qhwv thiab fasteners, cuam tshuam rau kev nyab xeeb.
Yuav ua li cas xaiv qhov tsim nyog modulus ntawm elasticity raws li ib puag ncig khiav?
Rau cov kab hauv nroog, thaj chaw nyob, nyob ze cov tsev kawm ntawv, thiab tsev kho mob, qis -modulus, siab- damping track pads yuav tsum yog qhov tseem ceeb. Rau cov txheej txheem rhiab heev xws li viaducts, txuas hniav, thiab qhov av, kev co -damping track pads nrog ib tug nruab nrab modulus yuav tsum tau xaiv. Rau siab - ntu kev ruaj ntseg xws li txoj kev loj thiab cov ntu ncaj, siab - lub zog pads nrog ntau dua modulus raug xaiv kom sib npaug kev ruaj ntseg thiab lub neej ntev.
