Cov hlau nrum feem ntau xaiv rau nws lub peev xwm los nqus cov kev co thiab suab nrov. Qhov no ua rau nws zoo tag nrho rau kev tsim cov suab lus tsawg, qhov chaw ruaj khov nrog CNC machining.
Cam khwb cia hlau feem yog cov hlau uas muaj heev. Lawv kuj tseem damp vibrations zoo, ua rau lawv zoo tagnrho rau cov tshuab, tshuab, gearboxes, thiab brakes.
Kev co yog qhov tseem ceeb rau qee cov cuab yeej. Nws ua suab nrov, ua phem, thiab ua tsis tiav. Yog hais tias kev co lub zog ua haujlwm, nws nce ampitude.Txhua kev co cuam tshuam kev cuam tshuam kev cuam tshuam machinery qhov tseeb thiab qhov chaw ruaj khov. Nws tseem ua kom luv lub neej ntawm cov chaw xws li cov zog thiab cov kabmob. Siv cov ntaub ntawv nrog cov khoom muaj peev xwm siab yuav txo tau cov kev co thiab suab nrov. Txoj hau kev no yuav pab txuas lub neej kom ntev.
Daim duab qhia txog peb cov ntaub ntawv ntub dej vibrations. Grey cam khwb cia hlau damps lub nrawm dua, thiab tom qab ntawd hlau, nrog txhua cov khoom damping ntawm li ib nrab ntawm ib qho ua ntej nws.
Vim li cas thiaj li damping tus yam ntxwv ntawm grey cam khwb cia hlau thiaj li zoo? Ntawm no peb yuav tsum tau hais txog cov kab lus uas tsis tau paub dua rau txhua tus, uas yog, kev sib txhuam ntawm cov tshuab sib txhuam thiab tshuab hluav taws xob. Txawm hais tias muaj cov khoom siv tsis sib xws poob cov tshuab hluav taws xob lub sijhawm vim kev sib txhuam sab hauv. Qhov kev sib txhuam sab hauv yog txuas rau cov khoom siv microstructure, thiab sab nraud ib puag ncig.Qhov no tuaj yeem tso tawm raws li lub spectrum raws li qhov kub thiab txias, lossis ntxhov siab.
Daim duab muab kev sib txhuam sab hauv hauv graphite, xim cam khwb cia hlau, thiab hlau ntshiab. Grey cam khwb cia hlau sab hauv kev sib txhuam nce ntau ntawm 180 thiab 250k. Nws nkhaus Correlates nrog graphite's, qhia tias graphite qhov kev tshem tawm ua rau cov khoom siv grey cam khwb cia hlau txoj kev damping.
Qhov saum toj no yog qee qhov kev piav qhia txog kev qhia rau vim li cas cam khwb cia hlau chaw tuaj yeem txo cov kev co thiab suab nrov. Nws yog me ntsis kev kawm thiab paub daws teeb. Txawm li cas los xij, nws yog kev paub nthuav dav rau txhua tus kom nkag siab.Kawm ntxiv txog cov ntaub ntawv cnc machining lossis nrhiav cov khoom siv CNC, thov nyem qhov no
Spheroidal cam khwb cia hlau muaj kev co phem damping vim nws cov qauv graphite. Tab sis nws muaj zog zoo li hlau, ua rau nws zoo tagnrho rau kev tseem ceeb siv qhov twg cov teeb meem kev co. Cov xim pob zeb grey yog qhov zoo dua rau cov xwm txheej tsis muaj kev ntxhov siab uas damping yog qhov tseem ceeb.(来源: Imchanics 机械)
