Txoj kev nkag
Mechanical admittance yog ib tug yam ntxwv parameter ntawm lub system nyob rau hauv zaus (saib mechanical impedance). Lub ntuj frequencies ntawm loj thiab complex lug muaj ntau heev thiab ntom, thiab cov kev co hom yog complex, uas tsis tuaj yeem ntsuas los ntawm txoj kev yooj yim. Txawm li cas los xij, cov lus teb ntawm lub kaw lus rau lub zog excitation tuaj yeem raug kuaj ua ntej kom tau txais cov neeg kho tshuab nkag, thiab tom qab ntawd cov qauv tsis muaj lossis lub cev tsis tuaj yeem txiav txim siab los ntawm kev txheeb xyuas cov duab (xws li amplitude zaus, theem zaus, zaus tiag, virtual zaus lossis vector. terminal diagram of the mechanical admittance) lossis computer identification.
Kev txheeb xyuas lub sijhawm
Lub modal tsis ntawm lub system tuaj yeem tau ncaj qha los ntawm kev siv lub sijhawm keeb kwm ntawm kev co. Rau kev vibration dawb, cov qauv tsis tuaj yeem suav ncaj qha los ntawm kev sib raug zoo ntawm kev vibration dawb thiab impulse teb muaj nuj nqi (ib qho ntawm lub sijhawm ua tus yam ntxwv ntawm lub kaw lus, uas Fourier hloov pauv yog kev nkag mus rau cov tshuab). Rau kev quab yuam quab yuam, cov qauv tsis muaj peev xwm suav tau los ntawm digital time series tsom txoj kev lossis lwm txoj hauv kev (xws li random decrement method, filtering method, etc.). Qhov kom zoo dua ntawm lub sij hawm domain identification txoj kev yog nws muaj peev xwm ua rau siv lub vibration teeb liab ntawm lub tshuab nyob rau hauv lub khiav lub xeev, uas yog haum rau loj-scale qauv uas yuav tsis tau kuaj nyob rau hauv lub laboratory; qhov tsis zoo yog tias lub zog excitation ntawm ntuj vibration qhov chaw feem ntau tsis tuaj yeem ntsuas thiab tswj tau, tab sis tsuas yog tuaj yeem txheeb xyuas los ntawm tus nqi teb, yog li qhov tseeb yog tsawg.
Load ID nkag mus
Nws yog hais txog kev tsom xam thiab kev txiav txim siab ntawm qhov xwm txheej ntawm qhov kev vibration (yog nws tsis tu ncua lossis random? Puas yog lub zog ruaj khov lossis kev txav txav ruaj khov?...), propagation path and load spectrum (ie time history of load) imposed by vibration source. ntawm qhov system. Load identification, tseem hu ua kev kwv yees ib puag ncig, tuaj yeem muab cov ntaub ntawv rau kev txheeb xyuas cov lus teb dynamic thiab vibration vim li cas ntawm qhov system. Lub load ntawm cov qauv loj yog qhov nyuaj heev, nws yog qhov nyuaj rau kev ntsuas ncaj qha, tab sis qhov load ntawm lub kaw lus tuaj yeem txiav txim siab los ntawm cov lus teb teeb liab ntawm cov qauv thiab paub txog lej qauv ntawm lub kaw lus, thiab tom qab ntawd cov load spectrum tuaj yeem ua tau. tau los ntawm kev txheeb cais thiab kev sib txuas ua ke raws li cov ntaub ntawv nyob rau hauv ntau yam kev ua haujlwm. Cov khoom thiab kev nthuav dav ntawm qhov kev vibration tuaj yeem tau txais los ntawm lub zog spectrum tsom xam lossis kev txheeb xyuas kev sib raug zoo.
