Dab tsi yog Qhov Ncauj Ncauj, Vim Li Cas Railways Yuav Tsum Teeb Kab Ntsig

Feem ntau, txhawm rau hloov mus rau qhov nce thiab nqis ntawm cov av thiab txo cov nqi ntawm kev tsim kho, qhov ntev ntawm txoj kev tsheb ciav hlau txuas nrog cov ntu ncaj ncaj nrog cov nqes hav sib txawv vim muaj qhov sib txawv. Vim li no, ib qho kev hloov ntawm txoj kab nqes yog tsim ntawm qhov sib tshuam ntawm txoj kab nqes nqes thiab nqes nqes. Yog tias cov kab ntawm txhua txoj kab nqes nqes txuas rau hauv txoj kab tawg, nws txhais tau hais tias yuav tsum muaj "knuckle" ntawm txoj kab. Thaum lub tsheb hla qhov "knuckle", Kev sib raug zoo ntawm lub tsheb thiab txoj kev khiav yog qhia hauv daim duab hauv qab no.

Yog hais tias lub kaum sab xis ntawm lub "knuckle" yog me me (qhov sib txawv ntawm qhov chaw siab tshaj ntawm ob qhov chaw nyob ib sab yog qhov sib txawv heev), ces thaum lub tsheb ciav hlau hla qhov kev hloov ntawm txoj kab nqes, tag nrho lub tsheb ciav hlau yuav raug faib rau ntawm qhov chaw sib txawv, uas yuav ua rau coupler stress tshwm sim. Cov kev hloov pauv tau yooj yim rau kev tawg lossis decoupling.

Yuav ua li cas teem lub ntsug nkhaus?

1. Qhov tso cai ceev tsis tshaj 160km / h. Thaum siv cov kab nkhaus ntsug, yog tias qhov sib txawv ntawm qhov sib txawv ntawm qhov chaw nyob ib sab yog ntau dua 3‰, ntsug nkhaus yuav tsum tau teeb tsa. Lub vojvoog ntawm txoj kab ntsug yuav tsum tsis pub tsawg dua 10000m, thiab qhov nyuaj yuav tsum tsis pub tsawg tshaj 5000m.

2. Thaum qhov kev tso cai ceev yog siab tshaj 160km / h thiab txoj kab nqes algebraic sib txawv tsis tsawg tshaj li 1‰, yuav tsum tau teem ib ncig ntsug nkhaus. Lub vojvoog ntawm txoj kab ntsug yuav tsum tsis pub tsawg dua 15000 m, thiab qhov ntev yuav tsum tsis pub tsawg dua 25m.

3. Vertical curves yuav tsum tsis txhob overlap nrog ntsug nkhaus thiab transitional curves, thiab yuav tsum tsis txhob invade turnouts, regulators thiab exposed choj decks.

4. Nyob ntawm qhov ceev, lub vojvoog ntawm txoj kab ntsug yog qhov sib txawv, raws li pom hauv daim duab.

yuav ua li cas cim
Qhov chaw pib ntawm txoj kab nkhaus ntsug yog cim "SQ L=ntsug nkhaus ntev" ntawm lub duav tsheb ciav hlau, txoj hauj lwm ntawm txoj kab nqes hloov taw tes yog cim "SB R=ntsug nkhaus vojvoog" ntawm txoj kab tsheb ciav hlau lub duav, thiab qhov kawg txoj hauj lwm ntawm txoj kab nkhaus ntsug yog cim "SZ" ntawm lub duav tsheb ciav hlau L= ntsug nkhaus ntev", qhov loj ntawm lub cim yog tib yam li cov cim nkhaus, thiab xim liab thiab dawb.
