Ib qho ntawm cov laj thawj tseem ceeb ntawm lub nruas nres hauv ob sab phlu yog qhov tsis txaus sib txuam ntawm lub vojvoog sab hauv thiab sab nrauv ntawm cov khau nres, ua rau tsis sib xws kev ntxhov siab, kev ntxhov siab, thiab tawg tawg. Nws qhov tseem ceeb yog nyob rau hauv kev ua kom muaj kev sib raug zoo thoob plaws tag nrho cov arc saum npoo, zam kev ua haujlwm tsis ua haujlwm los ntawm "lifting ntawm ob qho kawg."
Failure Mechanism ntawm Inner Arc Radius Matching
- Tsis txaus Radius (Large Liner Curvature):Tsuas yog ob qho kawg hu rau tus brake khau, tawm hauv nruab nrab tsis txhawb nqa. Nyob rau hauv kev cuam tshuam braking, ob qho tib si xaus dais tag nrho cov load, ua rau nws tsis tshua muaj siab tawg.
- Tsis txaus Radius (Small Liner Curvature):Qhov no tsim qhov tshwm sim "lifted-up", nrog rau nruab nrab ntawm kev sib cuag thiab qhov kawg tsis txhawb nqa. Rov qab khoov ua rau qaug zog tawg.
- Ideal State:Lub vojvoog sab hauv arc nruj me ntsis phim rau sab nrauv ntawm lub khau nres, ua tiav 100% arc nto haum. Lub load yog sib npaug faib raws tag nrho cov kev sib txhuam nto, tshem tawm cov kev ntxhov siab hauv zos peaks.
Lwm yam tseem ceeb rau kev ua tsis tiav:
- Cov khoom siv tsis txaus cuam tshuam lub zog:Cov khoom sib txhuam muaj qhov tsis zoo toughness thiab tsis tuaj yeem tiv taus qhov cuam tshuam tam sim thaum lub tsheb hnyav braking.
- Thermal kev nyuaj siab:Nruam braking ua rau kub hloov pauv, thiab cov ntaub ntawv tsis zoo yog qhov ua rau thermal tawg tawm.
- Machining qhov tseeb sib txawv:Cov txheej txheem tsis ruaj khov hauv arc sib tsoo ua rau batch - mus rau -batch radius kam rau siab tshaj qhov txwv.
- Installation los yog deformation cuam tshuam:Nres khau deformation los yog tsis tsim nyog installation exacerbates lub me me vojvoog mismatch.
Ntsiab lus xaus
Lub vojvoog sab hauv kev sib piv yog qhov yuav tsum tau ua ua ntej geometric mob rau cov qauv kev ncaj ncees ntawm lub nruas nres hauv ob sab phlu; Txawm tias muaj cov ntaub ntawv tsim nyog, qhov tsis sib xws hauv lub vojvoog yuav ua rau muaj kev cuam tshuam hauv cheeb tsam overload tawg. Kev tsim khoom niaj hnub no, los ntawm qhov siab - precision puab vojvoog sib tsoo tshuab thiab cov khoom siv sim ib txhij (xws li kev ntsuas sib xyaw ua ke thiab qhov tuab), tswj xyuas qhov kev ua siab ntev, ua rau nws yog thawj txheej txheem qhia txog kev tiv thaiv kev puas tsuaj.
