Kev paub txog kev cuam tshuam ntawm Rail Corrugation ntawm Kev Nyuaj Siab Lub Neej ntawm Rail Clips
Vim li cas rail corrugation cuam tshuam rau lub neej qaug zog ntawm rail clips?
Rail corrugation ua rau muaj kev cuam tshuam ib ntus thaum lub tsheb ciav hlau hla, ua rau "tib yam - zaus" yuam kev vibrations ntawm cov tsheb ciav hlau thiab cov tsheb ciav hlau. Qhov kev vibration tsis tu ncua no ua rau muaj kev sib hloov kev ntxhov siab hauv cov kab tsheb ciav hlau, uas ua rau qaug zog tawg tom qab ntev - lub sij hawm tsub zuj zuj. Corrugation kuj tuaj yeem ua rau muaj kev sib haum xeeb ntawm cov tsheb ciav hlau clips, ntxiv dag zog rau kev ntxhov siab ntxiv. Kev vibration siv zog nce nrog lub amplitude ntawm corrugation, accelerating qaug zog puas tsuaj rau rail clip khoom. Thaum kawg, kev vibration tsis tu ncua yuav ua rau luv luv lub neej kev pab cuam ntawm cov tsheb ciav hlau clips, ua rau muaj qhov txawv txav.
Dab tsi yog qhov sib txawv ntawm qhov cuam tshuam ntawm rail corrugation nrog sib txawv wavelengths ntawm rail clips?
Luv -wavelength corrugation (xws li 25mm thiab 40mm) yog qhov ua rau txaus siab rau 2nd harmonic vibration ntawm rail clips, uas yog lub ntsiab ua rau qaug zog tawg ntawm rail clips. Ntawm qhov ntev -wavelength corrugation, thaum lub nthwv dej tob ntawm 120mm wavelength loj, nws yuav ua rau 6th harmonic vibration, uas ua rau poob qis hauv lub neej qaug zog ntawm kev tsheb ciav hlau clips. Vim lub zog tsis muaj zog, qhov ntev -wavelength corrugation ntawm 240mm muaj qhov cuam tshuam tsis zoo rau lub neej qaug zog ntawm kev tsheb ciav hlau. Nyob rau hauv tib lub nthwv dej qhov tob, luv-wavelength corrugation muaj qhov cuam tshuam loj dua ntawm kev co ntawm cov tsheb ciav hlau thiab qhov kev puas tsuaj sai dua. Qhov sib piv ntawm cov corrugation wavelength thiab lub ntuj zaus ntawm cov tsheb ciav hlau clip txiav txim siab qhov kev vibration amplification thiab tus nqi ntawm qaug zog puas.
Dab tsi yog qhov tseem ceeb ntawm kev ua haujlwm ntawm kev tsheb ciav hlau clips los tiv thaiv kev tsheb ciav hlau corrugation?
Rail clips yuav tsum muaj lub zog qaug zog ntau dua los tiv thaiv kev sib hloov kev ntxhov siab uas tsim los ntawm kev vibration ib ntus. Zoo elastic rov qab muaj peev xwm yog indispensable los txo residual deformation tom qab kev co. Cov khoom siv yuav tsum muaj qhov toughness zoo heev kom tsis txhob nkig tawg nyob rau hauv kev vibration. Tus qauv tsim yuav tsum optimize lub ntuj zaus kom txo tau qhov kev pheej hmoo ntawm resonance nrog rail corrugation zaus. Kev kho saum npoo yuav tsum txhim kho kev hnav tsis kam kom txo qis kev puas tsuaj ntxiv los ntawm kev sib txhuam kev co.
Yuav ua li cas txo qhov cuam tshuam ntawm corrugation ntawm rail clips los ntawm kev xaiv cov khoom?
Nyob rau hauv cov kab uas muaj qhov tshwm sim ntawm corrugation, alloy steel rail clips nrog lub neej qaug zog ntev yuav tsum nyiam dua li cov khoom siv caij nplooj ntoos hlav. Xaiv cov qauv tsheb ciav hlau nrog cov qauv tsim kho kom zoo, xws li kho tus ntoo khaub lig-sectional shape kom disperse stress concentration. Raws li kev faib tawm ntawm kev tsheb ciav hlau corrugation wavelengths nyob rau hauv kab, xaiv rail clips nrog mismatched ntuj frequencies kom tsis txhob resonance. Ua kom siab - elasticity nyob rau hauv - rail puag daim hlau kom nqus tau ib feem ntawm lub zog vibration thiab txo qhov kev ntxhov siab ntawm kev tsheb ciav hlau clips. Rau cov cheeb tsam uas muaj corrugation hnyav xws li me me - vojvoog curves, thickened lossis reinforced rail clips tuaj yeem xaiv.
Ntxiv nrog rau kev xaiv cov khoom, lwm txoj kev siv tau los tiv thaiv kev tsheb ciav hlau los ntawm kev cuam tshuam ntawm corrugation?
Tsis tu ncua tshuaj xyuas qhov teeb meem rail corrugation, thiab tam sim ntawd zom ntau dhau corrugation kom txo tau kev co excitation los ntawm qhov chaw. Txhim khu kev khiav tamping kev khiav hauj lwm los txhim kho ballast stability thiab txo kev co kev sib kis efficiency. Tsis tu ncua xyuas cov xwm txheej ntawm kev tsheb ciav hlau clips, thiab tam sim ntawd hloov cov neeg uas muaj kev qaug zog thaum ntxov kom tsis txhob muaj kev nthuav dav ntawm kev ua tsis tiav. Siv roj rau qhov chaw sib cuag ntawm cov tsheb ciav hlau thiab cov ntsia hlau kom txo tau kev puas tsuaj los ntawm kev sib txhuam kev co. Optimize tag nrho cov nruj sib txuam ntawm lub fastener system los tsim ib tug tsis system thiab tsis muaj zog qhov kev vibration siv los ntawm corrugation.
