Gantry architecture tsim ib qho teeb meem tshwj xeeb uas lwm qhov kev teeb tsa tsis raug zoo ib yam: kab kab rov tav hla ob qhov kev txhawb nqa, nqa lub tsheb thauj khoom txav mus rau qhov chaw raws nws qhov ntev, nrog rau txoj haujlwm thauj khoom tas li hloov cov nqaj ntawm kev thauj khoom zoo. Tau txais cov nqaj loj thiab qhov tawv nqaij tsis raug, thiab cov teeb meem uas tshwm sim yog gantry- tshwj xeeb - resonance ntawm qee qhov chaw nqa khoom, dual- tsav synchronization yuam kev, sag uas hloov nrog qhov chaw lub taub hau tshwm sim los zaum. Qhov no yog qhov nqaim, cov lus nug tshwj xeeb tshaj li "dab tsi yog cov khoom siv zoo tshaj plaws rau lub nqaj txav" feem ntau, thiab nws tsim nyog kho nws li ntawd.
Vim li cas Gantry Beams muaj qhov teeb meem tsim txawv dua li lwm cov qauv txav
Lub caj npab cantilevered los yog ib qho -axis linear theem muaj ib tug kuj ruaj load geometry - lub txav loj zaum ntawm ib tug paub offset, thiab cov qauv yog engineered nyob ib ncig ntawm qhov xwm txheej. Lub gantry crossbeam lub load geometry hloov tsis tu ncua thaum lub tsheb thauj mus los ntawm nws qhov ntev. Nyob ze ntawm qhov kawg, lub nqaj yog zoo- txhawb nqa thiab deflection tsawg heev. Nyob ze ntawm qhov nruab nrab ntawm qhov ntev ntev, tib lub tsheb thauj khoom hnyav ua rau muaj kev cuam tshuam ntau dua, vim tias lub nqaj yog coj tus cwj pwm ntau dua li qhov yooj yim - txhawb nqa nyob rau hauv qhov txav taw tes load dua li cov qauv nruj.
Qhov no yog qhov uas beam stiffness-rau- qhov hnyav piv tseem ceeb hauv gantry- txoj kev tshwj xeeb. Lub beam hnyav dua los tiv thaiv txoj hauj lwm no-dependent deflection zoo dua nyob rau hauv cov ntsiab lus kiag li, tab sis ntxiv inertia uas yuav tsum tau ceev thiab decelerated ntawm ob qho tag nrho ntawm lub gantry qauv - thiab nyob rau hauv dual-tsav gantry configurations, uas ntxiv inertia yuav tsum tau matcheeped precisely nyob rau hauv txhua txhua lub sij hawm tsav tsheb axis txav.
Dual{0}}Drive Synchronization: Qhov twg Beam Mass ncaj qha cuam tshuam rau qhov tseeb
Ntau lub siab -ceev gantry tshuab siv dual- tsav kev teeb tsa - ywj siab lub cev muaj zog ntawm txhua qhov kawg ntawm kab, hluav taws xob synchronized kom lub nqaj square mus rau nws txoj kev taug kev thaum nws txav mus. Qhov no synchronization yuav tsum tau them rau ib qho asymmetry nyob rau hauv lub beam lub loj faib los yog nruj, thiab ib tug hnyav dua, tsis nruj beam muab lubsynchronization systemntau los kho rau txhua qhov kev txav mus los. Lub teeb, tawv tawv - uas yog raws nraim li qhov zoo-engineered carbon fiber layup muab txheeb ze rau qhov sib npaug ntawm txhuas los yog steel qauv - txo cov neeg kho tshuab lub nra ntawm lub synchronization system, tawm ntau ntawm kev kho pob nyiaj siv rau cov khoom siv hluav taws xob tiag tiag es tsis them nyiaj rau cov qauv flex.
Qhov no tseem ceeb tshaj li qhov ceev nce. Ntawm qhov ceev mus los tsawg, lub nqaj hnyav dua lub inertia yog tswj tau. Ntawm qhov nrawm nrawm niaj hnub siab -ceev gantry systems tau teev tseg rau, beam loj dhau los ua ib qho tseem ceeb ntawm kev txwv ceev npaum li cas cov axis tuaj yeem txav tau thaum tseem tuav synchronization kam rau ua - uas yog qhov tseeb qhov xwm txheej uas carbon fiber ntau qhov tawv nqaij- rau {{5} hnyav dua kuv qhov sib txawv.
Resonant zaus: Qhov teeb meem uas tshwm sim ntawm qhov ceev tshwj xeeb, tsis yog txhua qhov ceev
Txhua lub gantry beam muaj ib tug natural resonant zaus, thiab yog hais tias lub tshuab kev khiav hauj lwm ceev ntau excites uas zaus - los ntawm kev rov acceleration cycles ntawm ib tug sib piv tus nqi - lub beam muaj peev xwm txhim kho kev ruaj ntseg oscillation uas degrades positioning qhov tseeb ntawm qhov tshwj xeeb ceev, txawm tias tib lub tshuab ua tau zoo hauv qab no los yog zoo dua ntawm qhov ceev ceev. Ib qho hnyav dua, qis dua - cov nqaj tawv feem ntau muaj qis dua resonant zaus, uas feem ntau yuav poob rau hauv kev ua haujlwm ceev. Cov pa roj carbon fiber ntau dua qhov tawv nqaij - rau - qhov hnyav piv feem ntau thawb lub nqaj resonant zaus siab dua, ntxiv rau sab nraud lub tshuab ua haujlwm hauv - cov qauv tsim muaj txiaj ntsig ntau dua li qhov kev txhim kho marginal, tshwj xeeb tshaj yog rau cov cav tov yuav tsum khiav thoob plaws ntau qhov ceev hauv cov txheej txheem sib txawv.
Qhov twg Qhov no tiag them tawm hauv kev tsim khoom
Cov ntaub ntawv hla mus rau carbon fiber gantry beams tsis paub meej. Kev daws teeb meem sai dua tom qab txhua qhov xwm txheej ceev, txo qhov kev hloov kho synchronization, thiab ntau zaus ntxiv los ntawm kev khiav hauj lwm ntau qhov sib xyaw ua kom lub sij hawm luv luv ntawm kev ua haujlwm ntawm siab -repetition txheej txheem - laser ua, siab - nrawm drilling, xaiv- thiab - qhov chaw ua haujlwm - qhov chaw ua haujlwm - qhov chaw ua haujlwm - axis ntawm qhov chaw ua haujlwm ntawm ntau txhiab zaus. Kev txhim kho ntawm ib qho kev txav me me; cov nyhuv cumulative thoob plaws ib hnub ntau lawm yog qhov uas nws ua qhov tseem ceeb rau kev txiav txim siab yuav khoom.
Dab tsi los txheeb xyuas ua ntej qhia txog Carbon Fiber Gantry Beam
Rau gantry - daim ntawv thov tshwj xeeb, nws tsim nyog nug tus neeg muag khoom rau cov kab hluav taws xob cov ntaub ntawv qhov tseeb ntawm cov ntaub ntawv txheeb ze rau koj lub hom phiaj kev khiav hauj lwm ceev, tsis yog ib qho generic nruj daim duab - cov lus nug resonance yog gantry- tshwj xeeb thiab yooj yim rau kev saib xyuas yog tias kev sib tham nyob ntawm cov khoom siv {{3}. Nws tseem tsim nyog lees paub tias yuav ua li cas cov kab hluav taws xob fiber ntau tso nyiaj rau lub dual - tsav tsheb thauj khoom tshwj xeeb, txij li qhov kev teeb tsa tau zoo rau ib qho - taw tes cantilever load tsis cia li ua ib yam li nyob rau hauv kev hloov, txoj hauj lwm -dependent load a gantry beam yeej muaj kev paub. Peb muab cov pa roj carbon fiber ntau precision beam Cheebtsam raws li ib feem ntawm peb cov khoom siv dav dav, thiab cov lus qhia siv tau los ntawm gantry - cov ntawv thov tshwj xeeb yog cov nqaj yuav tsum raug tsim los tiv thaiv qhov tseeb ntawm cov ntaub ntawv uas lub gantry tsim - tsis kho raws li kev hloov pauv rau txhua yam khoom siv ua ntej.
