Kev sib raug zoo ntawm coefficient ntawm kev sib txhuam thiab kev khiav hauj lwm kub
Ntxiv nrog rau qhov coefficient ntawm kev sib txhuam, kev ua haujlwm zoo ntawm lub ncoo nres kuj tseem ceeb. Ntau yam hlau thiab cov tebchaw siv los ua cov pawm nres tsuas yog siv tau ntawm qee qhov kub. Txhawm rau kom ua haujlwm tau zoo ntawm cov khoom siv hluav taws xob, cov chaw tsim khoom ntxiv cov hlau sib txawv lossis lwm yam khoom siv hluavtaws rau cov qauv ntawm cov brake pad, thiab siv qhov kub thiab txias kom fuse ntau cov ntaub ntawv rau hauv ib qho khoom sib xyaw.
Nws kuj yog vim tias tsis muaj lub tsheb ciav hlau tuaj yeem muaj tag nrho cov yam ntxwv hauv lub ntiaj teb tiag, yog li cov tuam txhab tsim cov khoom lag luam sib xws raws li qhov xav tau ntawm cov chaw sib txawv. Qhov sib txawv ntawm cov yam ntxwv ntawm txoj kev thiab kev sib tw nres nres yog nyob rau hauv qhov kub sib txawv tsim thaum nres. Lub tsheb sib tw yuav tsum tau ua haujlwm tas li 100 feem pua ntawm nws lub zog nres ntawm qhov nrawm nrawm, thiab qhov ntau ntawm kev hloov pauv ntawm lub zog kinetic rau hauv lub zog hluav taws xob yog qhov tsis xav txog rau txoj kev tsheb. Rau lub braking system siv nyob rau hauv txoj kev zoo tib yam, yog hais tias tus brakes siv tag nrho cov quab yuam rau li kaum lub sij hawm nyob rau hauv ib tug kab, lub nres nres yuav pib "kub tsis ua hauj lwm". Yog li ntawd, cov tawv tawv quab yuam siv hauv cov tsheb sib tw yuav tsum muaj kev sib txhuam coefficient ntawm qhov kub thiab txias, yog li ntawm qhov kub thiab txias, qhov sib txhuam coefficient yuav tsis zoo. Los ntawm daim duab saum toj no, peb tuaj yeem pom meej tias cov brakes siv hauv cov tsheb sib tw ua haujlwm ntau dua li cov brake pads siv hauv cov tsheb ua si ua ntej 250 degrees Celsius. Tab sis thaum qhov kub thiab txias ntawm 300 thiab 500 degrees, kev sib txhuam coefficient ntawm cov brakes siv hauv cov tsheb sib tw yog qhov zoo dua li siv hauv cov tsheb sib tw.
Puas yog qhov coefficient ntawm kev sib txhuam tseem ceeb, lossis qhov kov tseem ceeb?
Hauv lub ntiaj teb tiag tiag, muaj ntau tshaj peb hom nres nres?
Nws kuj tseem yuav tsum tau muab sau tseg tias thaum lub tshuab nres nres ua haujlwm, nws yuav tsum txo qis kev cuam tshuam rau kev tswj, uas yog, kev xav yuav tsum maj mam ua kom yooj yim rau kev tswj. Nres pads nrog ntau dua coefficient ntawm kev sib txhuam feem ntau muaj kev cuam tshuam ntau dua, uas tsis tsim nyog rau kev tuav. Yog li ntawd, rau cov neeg uas xyuam xim rau kev tuav ntawm lub brakes, los yog cov neeg uas yuav tsum tau siv lawv nyob rau hauv qhov chaw ntub dej, lawv yuav xaiv lub brakes nrog ib tug qis coefficient ntawm kev sib txhuam.
