Dynamic resistance yog hais txog tus nqi tsis kam ntawm kev sib cuag tsis kam ntawm txhuam thiab lub nplhaib conductive uas hloov pauv raws sijhawm, xwm txheej ua haujlwm thiab lwm yam thaum lub sijhawm ua haujlwm ntawm lub nplhaib conductive. Dynamic resistance muaj cov teebmeem tseem ceeb hauv qab no rau lub nplhaib conductive:
Kev cuam tshuam rau kev ua haujlwm hluav taws xob
a. Kev cuam tshuam rau qhov zoo ntawm kev xa cov teeb liab: Thaum lub sijhawm xa cov teeb liab, qhov muaj qhov tsis kam hloov pauv yuav ua rau cov teeb liab tsis zoo, tsis sib xws lossis cuam tshuam. Rau cov teeb liab tsis muaj zog lossis cov teeb liab zaus siab, kev hloov pauv ntawm qhov tsis kam hloov pauv yuav hloov cov yam ntxwv xws li qhov loj thiab theem ntawm cov teeb liab, yog li cuam tshuam rau qhov tseeb thiab kev ncaj ncees ntawm cov teeb liab. Piv txwv li, hauv cov khoom siv ntsuas qhov tseeb lossis cov kab ke sib txuas lus, qhov tsis ruaj khov ntawm qhov tsis kam hloov pauv yuav ua rau muaj qhov yuam kev ntsuas ntau ntxiv lossis qhov yuam kev me ntsis hauv cov teeb liab sib txuas lus.
b. Ua rau muaj cua sov thiab lub zog poob: Raws li Joule txoj cai, Q = I²RT, kev hloov pauv ntawm qhov tsis kam hloov pauv yuav ua rau muaj kev hloov pauv ntawm cua sov uas tsim los ntawm lub nplhaib conductive thaum lub sijhawm ua haujlwm. Thaum qhov tsis kam hloov pauv nce ntxiv, cua sov uas tsim los ntawm tib lub zog tam sim no nce ntxiv, uas yuav tsis tsuas yog ua rau muaj kev pov tseg zog xwb, tab sis kuj ua rau qhov kub ntawm lub nplhaib slip nce ntxiv, yog li cuam tshuam rau nws qhov kev ua haujlwm rwb thaiv tsev thiab kev ua haujlwm ntawm lwm yam khoom, thiab hauv cov xwm txheej hnyav tuaj yeem ua rau lub nplhaib slip puas tsuaj.
c. Ua rau muaj kev hloov pauv ntawm qhov hluav taws xob poob qis: Kev hloov pauv ntawm qhov tsis kam hloov pauv yuav ua rau qhov hluav taws xob poob qis ntawm ob qho kawg ntawm lub nplhaib sib nqus hloov pauv. Hauv cov kab ke xa hluav taws xob, qhov no yuav cuam tshuam rau qhov ruaj khov ntawm qhov kawg ntawm qhov thauj khoom thiab tiv thaiv cov khoom siv los ntawm kev ua haujlwm kom raug. Piv txwv li, hauv qee cov khoom siv hluav taws xob uas muaj qhov yuav tsum tau ruaj khov ntawm qhov hluav taws xob siab, qhov kev hloov pauv ntawm qhov hluav taws xob poob qis los ntawm qhov tsis kam hloov pauv yuav ua rau cov khoom siv tsis ua haujlwm lossis kev ua haujlwm poob qis.
Kev cuam tshuam rau cov khoom siv kho tshuab
d. Kev hnav ntau ntxiv: Qhov kev hloov pauv ntawm qhov tsis kam hloov pauv feem ntau yog nrog los ntawm kev hloov pauv ntawm lub xeev sib cuag ntawm txhuam thiab lub nplhaib conductive. Thaum qhov tsis kam hloov pauv nce ntxiv, qhov siab sib cuag ntawm txhuam thiab lub nplhaib conductive yuav hloov pauv, ua rau muaj kev sib txhuam ntau ntxiv, uas ua rau kev hnav ntawm txhuam thiab lub nplhaib conductive nce ntxiv. Kev hnav yuav ua rau lub neej ua haujlwm ntawm lub nplhaib conductive luv dua, ua rau cov nqi kho thiab lub sijhawm tsis ua haujlwm ntawm cov khoom siv.
e. Kev cuam tshuam rau kev hloov pauv ntawm lub nplhaib: Qhov kub thiab kev sib txhuam ntxiv uas tsim los ntawm kev hloov pauv ntawm qhov tsis kam ua haujlwm yuav ua rau cov khoom tig ntawm lub nplhaib sib tsoo raug kev ntxhov siab thermal thiab mechanical. Kev sib sau ua ke ntev yuav ua rau cov khoom tig deform thiab jam, cuam tshuam rau kev hloov pauv ntawm lub nplhaib sib tsoo, thiab tom qab ntawd cuam tshuam rau kev ruaj khov ntawm tag nrho cov khoom siv.
Kev cuam tshuam rau kev ruaj khov thiab kev ntseeg siab ntawm lub kaw lus
a. Ua rau lub kaw lus tsis ua haujlwm: Hauv qee lub kaw lus nyuaj, qhov tsis ruaj khov ntawm qhov tsis kam ntawm lub nplhaib conductive slip yuav ua rau muaj kev sib txuas lus, ua rau tag nrho lub kaw lus tsis ua haujlwm. Piv txwv li, hauv cov teb ntawm aerospace, kev lag luam automation, thiab lwm yam, lub nplhaib conductive slip yog ib qho tseem ceeb. Qhov kev hloov pauv tsis zoo ntawm nws qhov kev tiv thaiv dynamic yuav ua rau lub kaw lus tswj hwm ua haujlwm tsis zoo lossis ua rau cov khoom siv poob kev tswj hwm.
b. Txo qhov kev ntseeg siab ntawm lub kaw lus: Qhov muaj qhov tsis kam hloov pauv ua rau muaj qhov tsis paub meej ntawm lub xeev ua haujlwm ntawm lub nplhaib sib nqus, uas ua rau qhov kev ntseeg siab ntawm lub kaw lus txo qis. Txij li thaum qhov tsis kam hloov pauv cuam tshuam los ntawm ntau yam, xws li qhov kub thiab txias, av noo, kev co, thiab lwm yam, nws cov kev hloov pauv nyuaj rau kev kwv yees thiab tswj hwm, uas coj kev phom sij zais rau kev ua haujlwm ruaj khov mus sij hawm ntev ntawm lub kaw lus.
