thev naus laus zis loj | Kev lag luam tshiab | Plaub Hlis 16, 2025
Hauv kev ua tub rog niaj hnub no, ntau yam khoom siv nyuaj muaj qhov xav tau siab heev rau kev xa cov cim thiab lub zog ruaj khov. Txij li cov kab ke avionics ntawm cov dav hlau sib ntaus sib tua mus rau cov radar arrays ntawm cov tub rog sib ntaus sib tua, cov nplhaib sib tsoo yog cov khoom tseem ceeb rau kev ua tiav cov cim thiab lub zog xa mus ntawm cov khoom sib hloov, thiab lawv cov kev ua tau zoo yog cuam tshuam ncaj qha rau kev ua tiav lossis tsis ua tiav ntawm cov haujlwm tub rog. Hauv kev ua haujlwm tub rog, cov nplhaib sib tsoo yog qhov tseem ceeb rau kev xa cov cim thiab lub zog hauv cov kab ke sib hloov, thiab kev cuam tshuam hluav taws xob (EMI) yog qhov txaus ntshai loj. Ingiant Slip Rings siv cov qauv tsim tiv thaiv kev cuam tshuam siab heev xws li ntau txheej EMI shielding, cov ntaub ntawv khov kho thiab cov thev naus laus zis sib cuag kom ntseeg tau tias nws cov khoom ua tau raws li cov qauv tub rog nruj thiab ua tau zoo hauv cov chaw muaj hluav taws xob hnyav. Nws cov khoom suav nrog ntau hom, haum rau ntau yam xwm txheej tub rog, thiab tau raug sim ua kom ntseeg tau tias ua tau zoo hauv cov ntawv thov tiag tiag.
Qhov tseem ceeb ntawm kev tsim qauv tiv thaiv kev cuam tshuam ntawm cov nplhaib sib tsoo qib tub rog
Hauv cov xwm txheej sib ntaus sib tua tiag tiag, cov nplhaib sib tsoo yog lub luag haujlwm rau kev xa cov lus qhia tseem ceeb, cov ntaub ntawv tiag tiag, thiab lub zog ruaj khov rau cov khoom siv tig. Piv txwv li, siv lub tshuab tig ntawm lub tank sib ntaus sib tua loj, lub nplhaib sib tsoo yuav tsum xyuas kom meej tias cov lus qhia tseeb ntawm lub kaw lus tswj hluav taws, cov ntaub ntawv tawm tswv yim ntawm lub sensor ntawm lub thoob, thiab lub zog ntawm lub cev muaj zog tsav tuaj yeem xa mus tsis tu ncua. Tej qhov yuam kev me me yuav ncua lub sijhawm los sib ntaus sib tua. Lub tshav rog niaj hnub no puv nrog kev cuam tshuam hluav taws xob los ntawm cov khoom siv hluav taws xob ntawm cov yeeb ncuab, cov kab ke sib txuas lus zoo, thiab ib puag ncig ntuj. Thaum cov teeb liab cuam tshuam no nkag mus rau hauv txoj kab sib kis ntawm lub nplhaib sib tsoo, lawv yuav ua rau cov ntaub ntawv poob thiab teeb liab cuam tshuam, lossis txawm tias ua rau tag nrho cov khoom siv tsis ua haujlwm. Piv txwv li, hauv kev ua tsov rog hluav taws xob, cov hluav taws xob muaj zog uas cov yeeb ncuab tso tawm yuav ua rau lub teeb liab xa los ntawm lub nkoj lub nplhaib sib tsoo tsis sib haum xeeb, ua rau lub radar tsis tuaj yeem ntes lub hom phiaj ib txwm muaj, yog li ua rau lub nkoj muaj kev phom sij. Nws tuaj yeem pom tias kev tsim qauv tiv thaiv kev cuam tshuam ntawm cov nplhaib sib tsoo tub rog yog qhov txuas tseem ceeb los xyuas kom meej tias kev ua haujlwm ntawm cov khoom siv txhim khu kev qha thiab txhim kho kev ua haujlwm ntawm cov tub rog.
Kev tshuaj xyuas tsim qauv tiv thaiv kev cuam tshuam
Txhua yam kev tiv thaiv EMI / EMC
Yuav kom tiv taus kev cuam tshuam electromagnetic, cov nplhaib sib txuas lus tub rog yuav tsum tsim kom muaj lub kaw lus tiv thaiv txhua yam. Hauv kev xaiv cov ntaub ntawv sib cuag, cov hlau muaj nqis siab siv cov hlau ntshiab, xws li cov ntaub ntawv rhodium-plated thiab palladium-plated. Cov ntaub ntawv no tsis tsuas yog muaj kev coj ua zoo heev, tab sis kuj tsim cov txheej txheem tiv thaiv electromagnetic zoo kom txo qhov xau ntawm cov teeb liab thiab kev cuam tshuam sab nraud. Piv txwv li, siv lub nplhaib radar ntawm ib hom dav hlau ceeb toom thaum ntxov, cov neeg sib cuag rhodium-plated txo qhov cuam tshuam ntawm cov teeb liab electromagnetic zaus siab ntawm kev xa cov ntaub ntawv radar, thiab nce qhov deb ntawm radar nrhiav pom los ntawm 15%. Tib lub sijhawm, ntau txheej txheej sib xyaw ua ke kuj yog ib txoj hauv kev siv ntau. Los ntawm kev sib xyaw ua ke ntawm cov hlau mesh, roj hmab conductive thiab lub hau tiv thaiv, qhov cuam tshuam tiv thaiv zoo ib yam li Faraday tawb tau tsim. Hauv lub nplhaib sib hloov ntawm lub tsheb sib txuas lus tub rog, cov qauv tiv thaiv ntau txheej no ua tiav tiv taus kev cuam tshuam ntawm ib puag ncig electromagnetic thiab ua kom muaj kev sib kis ruaj khov ntawm cov teeb liab sib txuas lus. Ntxiv rau, thev naus laus zis sib txuas ua ke cov fiber ntau optical nrog kev xa hluav taws xob, thiab siv cov yam ntxwv ntawm cov fiber ntau optical uas tsis raug cuam tshuam los ntawm electromagnetic kom ua tiav kev xa cov ntaub ntawv tseem ceeb kom muaj kev nyab xeeb, ntxiv cov kev lees paub tshiab rau kev tsim qauv tiv thaiv kev cuam tshuam.
Kev ruaj khov ntawm cov ntaub ntawv thiab cov qauv
Cov nplhaib sib nqus qib tub rog ntsib teeb meem ib puag ncig hnyav heev, yog li kev xaiv cov ntaub ntawv thiab cov qauv yog qhov tseem ceeb heev. Hais txog cov ntaub ntawv plhaub, cov hlau titanium muaj zog siab, hlau tsis xeb thiab lwm yam khoom siv hlau tau siv dav. Cov ntaub ntawv no tsis tsuas yog muaj kev tiv thaiv corrosion zoo heev, tab sis kuj muab kev tiv thaiv electromagnetic zoo rau cov khoom sab hauv. Piv txwv li, cov nplhaib sib nqus siv hauv submarine periscopes, uas lawv cov plhaub hlau tsis xeb tseem tuaj yeem tiv thaiv cov khoom xa xov sab hauv hauv qab dej hiav txwv corrosion thiab qhov chaw siab siab. Hauv kev tsim cov qauv sealing, ob chav sealing technology tau txais yuav, ua ke nrog cov tub rog-tus qauv O-rings kom ntseeg tau tias cov nplhaib sib nqus muaj cov dej tsis kam, plua plav thiab xuab zeb zoo heev. Hauv qhov chaw sib ntaus sib tua hauv suab puam, cov tsheb thauj khoom uas muaj cov qauv sealing slip rings tseem tuaj yeem ua kom muaj kev ruaj khov ntawm kev xa xov txawm tias muaj cua hlob thiab xuab zeb. Tib lub sijhawm, kev tsim qauv kho tshuab zoo tshaj plaws txhim kho kev tiv thaiv kev co thiab kev cuam tshuam ntawm lub nplhaib sib nqus, ua rau nws hloov kho rau kev ntxhov siab tshuab los ntawm cov khoom siv tub rog thaum tsav tsheb ntawm thaj chaw nyuaj thiab kev ua haujlwm hnyav.
Kev daws teeb meem kev ncaj ncees ntawm lub teeb liab
Yuav kom ntseeg tau tias lub teeb liab muaj kev sib raug zoo thaum lub sijhawm xa xov, Ingiant cov nplhaib sib txuas lus tub rog siv ntau yam thev naus laus zis tshiab. Cov thev naus laus zis cais zaus ua kom cov teeb liab ntawm ntau zaus sib txawv zoo los ntawm kev tsim cov lim dej tshwj xeeb thiab cov khoom siv cais kom tsis txhob muaj kev cuam tshuam. Hauv lub nplhaib sib txuas lus ntawm ib hom kev tiv thaiv foob pob hluav taws, cov thev naus laus zis cais zaus tiv thaiv cov teeb liab tswj thiab cov teeb liab tawm tswv yim sensor los ntawm kev cuam tshuam nrog ib leeg, yog li txhim kho qhov tseeb ntawm lub foob pob hluav taws. Kev tsim qauv suab nrov qis pib los ntawm kev teeb tsa circuit, kev xaiv cov khoom, thiab lwm yam kom txo cov teeb liab suab nrov tsim hauv lub nplhaib sib txuas lus. Piv txwv li, hauv lub nplhaib sib txuas lus ntawm cov khoom siv avionics, cov amplifiers suab nrov qis thiab cov qauv luam tawm Circuit Court board zoo tshaj plaws tau siv los txhim kho qhov sib piv ntawm cov teeb liab mus rau suab nrov ntawm kev xa xov. Tsis tas li ntawd, kev kuaj mob ntse thiab kev them nyiaj thev naus laus zis maj mam siv rau kev tsim lub nplhaib sib txuas lus. Qhov xwm txheej ua haujlwm thiab qhov zoo ntawm lub nplhaib sib txuas lus raug saib xyuas lub sijhawm tiag tiag los ntawm cov sensors ua ke. Thaum pom kev cuam tshuam lossis qhov tsis zoo, lub kaw lus yuav them nyiaj thiab kho kom ntseeg tau tias kev xa xov teeb liab ruaj khov.
Cov txiaj ntsig zoo ntawm cov khoom siv nplhaib zoo heev rau tub rog
Lub nplhaib sib nqus ntau lub teeb liab
Cov nplhaib sib nqus uas hla dhau qhov yog ib hom uas siv ntau hauv cov khoom siv tub rog, thiab lawv qhov tsim qhov chaw nruab nrab tshwj xeeb muab kev yooj yim rau kev txuas xov hlau. Hauv UAV cluster combat system, qhov chaw nruab nrab ntawm lub nplhaib sib nqus uas hla dhau qhov tuaj yeem siv los hla ntau yam xov hlau xws li cov xov hlau fais fab thiab cov xov hlau ntaub ntawv kom ua tiav cov teeb liab thiab kev xa hluav taws xob ntawm UAV lub cev thiab lub kiv cua tig.
