1. Cov kev tsheb ciav hlau ua haujlwm li cas nyob rau hauv kev sib haum xeeb kev co?
Resonant zaus tuaj yeem ua kom sib koom ua ke kom qaug zog. Kev tsim kom zoo damping txo cov teebmeem harmonic. Bolt ua ntej-load cuam tshuam rau kev vibration kis tus yam ntxwv. Nruam welded rail txo qhov kev sib haum xeeb excitation. Kev soj ntsuam qib siab pom muaj teeb meem kev co.
2. Dab tsi yog qhov tshwj xeeb uas yuav tsum tau ua rau kev sib koom ua ke ntawm kev tsheb nqaj hlau hauv thaj chaw tshuaj lom neeg?
Tshuaj-cov ntaub ntawv tiv thaiv tiv thaiv corrosion los ntawm kev nchuav. Spark- yuav tsum tau tsim cov qauv tiv thaiv. Kev ntim tshwj xeeb tiv thaiv kev sib koom ua ke ntawm cov roj nplua nyeem. Kev tshuaj xyuas ntau zaus saib xyuas cov tshuaj lom neeg raug. Cov txheej txheem kho thaum muaj xwm txheej ceev hais txog kev phom sij.
3. Kev saib xyuas kev sib koom ua ke txawv li cas hauv DC vs AC electrified systems?
DC systems xav tau kev saib xyuas ntxiv rau electrolytic corrosion. AC systems yuav tsum tau ceev faj saib xyuas cov teebmeem inductive. Cov txheej txheem sib txawv yog siv rau txhua qhov system. Cov kev xav tau ntawm rwb thaiv tsev sib txawv raws li hom voltage. Cov txheej txheem kev nyab xeeb txawv rau cov neeg ua haujlwm tu.
4. Dab tsi yog qhov zoo ntawm kev siv cov duab nco alloys hauv cov pob qij txha rail?
Cov duab cim xeeb ua kom haum rau thermal expansion. Tus kheej -tightening peev xwm tuav lub bolt nro. Enhanced qaug zog tiv thaiv ncua kev pab cuam lub neej. Kev puas siab puas ntsws yog txhim kho los ntawm pseudoelasticity. Txo cov kev tu xyuas kom txo cov nqi ntawm lub neej.
5. Cov kev tsheb ciav hlau cuam tshuam li cas rau pantograph-catenary cuam tshuam?
Kev sib koom ua ke -vim kev co tuaj yeem xa mus rau cov kab hla. Kev kho kom zoo sib koom ua ke khaws cov kev sau zoo tam sim no. Rail muaj peev xwm hloov pauv tau tswj tau ntawm cov pob qij txha. Kev saib xyuas tshwj xeeb yog xav tau ntawm cov chaw sib koom ua ke. System- kev sib koom ua ke thoob plaws suav nrog kev sib koom ua ke.
