Nruam Welded Rail (CWR) Kev Sib Tw thiab Kev Tsim Kho Tshiab
Continuous Welded Rail (CWR) yog ib txoj hauv kev tso cov kev tsheb ciav hlau nyob rau hauv uas cov tsheb ciav hlau tau welded ua ke los tsim cov kab nrib pleb uas tsis muaj qhov khoob lossis pob qij txha. Thaum CWR muaj ntau yam zoo dua li kev sib koom ua ke ntawm txoj kev tsheb ciav hlau, xws li kev caij tsheb sib tw, txo kev saib xyuas, thiab muaj kev nyab xeeb ntxiv, nws kuj muaj qee qhov kev sib tw tshwj xeeb. Nov yog qee qhov kev sib tw thiab kev tsim kho tshiab cuam tshuam nrog CWR:
- Thermal Expansion thiab Contraction
Ib qho ntawm cov teeb meem tseem ceeb nrog CWR yog tswj cov thermal expansion thiab contraction ntawm cov ntsia hlau, uas tuaj yeem ua rau buckling los yog taug qab misalignment. Kev tsim kho tshiab hauv kev tsheb ciav hlau nrawm, xws li kev siv cov hlua khi hlua khi thiab cov hlua txuas txuas txuas txuas ntxiv, pab kom haum rau cov thermal fluctuations thaum tswj kev sib dhos.
- Weld Zoo thiab kev ncaj ncees
Ua kom ntseeg tau qhov zoo thiab kev ncaj ncees ntawm kev tsheb ciav hlau welds yog qhov tseem ceeb rau kev ua haujlwm thiab kev nyab xeeb ntawm CWR. Kev tsim kho tshiab hauv vuam thev naus laus zis, xws li automated flash butt welding thiab thermite welding, tau txhim kho qhov zoo thiab sib xws ntawm txoj kev tsheb ciav hlau, txo qhov kev pheej hmoo ntawm qhov tsis xws luag thiab tsis ua haujlwm.
- Longitudinal thiab Lateral Forces
CWR muaj kev cuam tshuam rau lub zog ntev thiab sab nraud uas tshwm sim los ntawm cov yam ntxwv xws li tsheb ciav hlau nres, nrawm, thiab kev txav mus rau sab nraud. Kev tsim kho tshiab hauv kev tsheb ciav hlau nrawm, xws li kev ruaj ntseg fastenings thiab txhim kho kev tsim qauv duab, pab txo cov quab yuam thiab tswj kev ruaj ntseg.
