1. Txoj kev tsheb ciav hlau hloov tau li cas rau thaj chaw suab puam?
Desert rail adaptations muaj xws li:
Xuab zeb- tiv taus cov ntsaws ruaj ruaj ntawm fasteners
Hnub ci- cov coatings reflective
Nce clearance rau dune encroachment
Plua plav -Suppression water spray systems
Kev tswj cov cua kub yog qhov tseem ceeb nrog 50℃+ txhua hnub viav vias.
2. Lub hom phiaj ntawm rail lubrication nyob rau hauv keyboards yog dab tsi?
Hloov lubrication:
Txo qhov taw tes hniav hnav
Tiv thaiv kom tsis txhob muaj daus / dej khov
Minimizes actuator loads
Biodegradable greases yog siv los ntawm cov tshuab tsis siv neeg txhua 200-300 lub tsheb ciav hlau hla.
3. Yuav ua li cas koj xam rail dabtsi yog khoov kev nyuaj siab?
Hloov pauv Euler-Bernoulli kab zauv nyiaj rau:
σ = (M·y)/I + P/A
Qhov twg: M=Bending moment y=Distance from neutral axis I=Moment of inertia P=Axial load A=Hla-sectional area
Kev txwv tsis pub muaj kev ntxhov siab feem ntau yog 250-300MPa rau cov qauv tsheb ciav hlau.
4. Dab tsi yog qhov ntsuas ntawm kev tsheb ciav hlau qaug zog?
Cov cim ceeb toom ntxov muaj xws li:
Plhaub(surface cracks parallel to rail)
Paub meej pob txha(Internal angled tawg)
Transverse fissures
Acoustic emission sensors tuaj yeem ntes cov kab nrib pleb tawm ua ntej pom cov cim tshwm.
5. Txoj kev tsheb ciav hlau tiv thaiv li cas hauv txoj hauv kev hluav taws xob?
Kev ntsuas rwb thaiv tsev muaj xws li:
Composite insulator pads
Dielectric roj rau ntawm fasteners
Zinc{0}}coated clearance washers
Voltage gradients tshaj 5V / m yuav tsum tau mitigation los tiv thaiv stray tam sim no corrosion.
