Tsis yog nws tsis hloov raws li lub kaum sab hloov: kev sib txhuam coefficient tsuas yog nyob ntawm qhov xwm ntawm cov ntaub ntawv hauv kev sib cuag.
Puas coefficient ntawm kev sib txhuam ib txwm zoo ib yam?
Tus coefficient ntawm kev sib txhuam tsis yog ib txwm zoo ib yam rau cov khoom uas tsis muaj zog thiab cov khoom uas nyob hauv kev txav; Cov khoom tsis muaj zog feem ntau muaj kev sib txhuam ntau dua li kev txav mus los, xav tau ntau lub zog los tso rau hauv kev txav dua li txhawb nqa lawv hauv kev txav.
Yuav tsum tus coefficient ntawm kev sib txhuam hloov nrog lub kaum sab xis?
Tam sim no, tus coefficient ntawm kev sib txhuam yog cov khoom ntawm cov khoom, thiab tsis hloov nrog lub kaum sab xis- tab sis nws yog rooj plaub uas qhov kev sib txhuam quab yuam yuav txo qis vim nws yog Fk=μkFn.
Dab tsi tuaj yeem cuam tshuam qhov coefficient ntawm kev sib txhuam?
Txoj kev sib txhuam ntawm ob lub cev yog nyob ntawm peb yam: (I) qhov adhesion ntawm lub cev nto (ii) roughness ntawm qhov chaw (iii) deformation ntawm lub cev.
Vim li cas tus coefficient ntawm kev sib txhuam hloov thaum tsuas yog ib qho ntawm qhov chaw hloov?
Cov kev sib txhuam coefficient yuav hloov nrog lub sijhawm vim qhov chaw ntawm kev sib cuag yuav hloov pauv. Kev sib txhuam coefficient nyob ntawm ntau yam ntawm lawv koj yuav pom qhov chaw micro topography hauv cheeb tsam hu.
