Lub Tebchaws Txheem Rail Dail Lub Zog Kev Tsim Nyog thiab txhim kho Scooting Performance
- Yuav ua li cas txhim kho lub 25kn / m anti - bending txhav ntawm GB 601/06 Kev Hloov Kho, thiab yog dab tsi yog tus tshaj tawm hloov kho?
Tsis muaj zog ua rau muaj kev nthuav dav 1mm / peb hlis. Hloov kho: ① 16 → 16.8mm lub vev xaib tuab; ② CNC dov (qis dua los yog sib npaug ± 0.1mm sib txawv); ③ Ultrasonic Qhov Ntsuas Kom Paub Tias (tsawg dua lossis sib npaug rau 0.2 hli tawg). Cov Qauv: 16.6 {13- 16.9mm thickness, ntau dua los yog sib npaug rau 1.5mm / tsawg dua lossis sib npaug nrog 0.3mm / peb hlis nthuav dav. Qhov tshwm sim: 1 Haum / Ib nrab xyoo, haum 25t Rail.
- Yuav ua li cas thiaj ua tau zoo stiffeners rau GB 75kg / m tsheb ciav hlau (380MPA Web kev nyuaj siab) kom tawg kev ntxhov siab, thiab yog dab tsi muaj stiffener parameter muaj?
Tsis muaj stiffeners ua rau 8% tawg tus nqi / xyoo. Kev ua kom zoo: ① 8mm × 6mm Triangular stiffeners (ob sab); ② 2mm hloov arc; ③ 500 hli spacing. Cov tsis muaj: 7.8- 8.2 hli qhov siab, 5.8-6.2mm puag, 1.8-2.2 hli arc, 490-510mm txuas. Qhov tshwm sim: 320MPA kev ntxhov siab, 1.2% tawg tus nqi, 35kn / mm txhav, haum 30t hnyav-haul.
- Dab tsi yog qhov kev ntsuas kev ua haujlwm tau kev ua tau zoo / qauv rau GB Rails nrog kev siv nyiaj Gailness (ntau dua lossis sib npaug nrog 60kg / m rail?
Kev Xeem: ① 2m piv txwv, 50kning txuas; Renplacement sensor rau txhav; ③ 3 rov ua dua. Cov Qauv: Loj dua lossis sib npaug rau 30kn / MM (M), ntau dua lossis sib npaug lossis sib npaug lossis sib npaug ntawm 0.1mm feeddual deformation. Tuav: ① Ntxiv 5mm uxiliary stiffeners (200mm spacing); ② Cov vuam hauv zos (tsawg dua los yog sib npaug rau 0.3mm); ③ Rov {13 {}} ntsuas ntau dua lossis sib npaug rau 30knon / hli.
- Dab tsi yog lub cuab lub zog sib txawv rau GB ntsia hauv 200m / 300m nkhaus, thiab ua li cas nrog mismatch (piv txwv li, 300m tsis yog 200m)?
Qhov sib txawv: ① 200m: 60kg / m (17mm, 9mm stiffener), 75kg / m (18mm, 10mm); ② 300M: 60KG / M (16.8mm, 8mm), 75kg / m (17.5mm, 9mm); ③ 500m: 60kg / m (16.5mm, tsis muaj), 75kg / m (17mm, tsis muaj). Miscatch: 390MPA kev nyuaj siab, 2.5mm dabtsi yog khoov / 6 lub hlis, 400k RMB / 100km nqi.
- Yuav ua li cas kho cov nrawm dua kom haum gb rails nrog kev siv hluav taws xob nrog kev siv hluav taws xob, thiab muaj dab tsi tshwm sim nrog kev haum xeeb?
Hloov kho: ① 16 → 16.8mm Fastener Clamp (60kg / m); 0.5mm Bolt Offset; Muaj ntau dua lossis sib npaug ntawm 95% tiv tauj thaj tsam. Cov Qauv: Loj dua los yog sib luag rau 8k clamping, tsawg dua lossis sib npaug nrog 0.3mm hloov, tsawg dua los yog sib npaug rau 10 hli sib txawv. Tsis zoo haum: 6K clamping, 0.4g kev co,> 88db suab, 0.4mm Faster hnav / xyoo, 25% tus nqi kho tus nqi.
