Lub hauv paus rau phau ntawv
Poob Siab Thiab Kev CoYog lub hauv paus ntawm lub tsev hauv paus ntawm kev tiv thaiv niaj hnub thiab aerospace engineering, kom ntseeg tau qhov kev ntseeg tau thiab precision ntawm cov kev mob siab.Tej thaj chaw deb tswj cov khoom siv phom (RCWs), tuaj yeem ntsia tau ob qho tib si ntawm lub tsheb uas muaj sia (thaj av), thiab cov tsheb Aerial Aerial (ubs), ua piv txwv txog cov kev sib tw tsis sib haum. RCWs tsheb-BORE yuav tsum tuKev Cuam Tshuam Kev Xav Zoo Siab(eg {{50-100 g) los ntawm rab phom thiab tsawg-zaus dibrations (} hz), tswj qee tus qauvBoresight Khaws.
Txawm li cas los xij, thaum ua lub luag haujlwm raws li cov paysload ntawm UAVS, feem ntau, nws lub ntsej muag txuas ntxiv brourbim lossis cua hlob ({} g). Cov ntawv sau no muab cov ntsiab lus dav dav ntawmPoob Siab Thiab Kev Co Cev Rho Tawm, tom qab ntawd tshawb nrhiav vim li cas lub tsheb-brone rcws nyiamDamping thiab Embedded Ironators(xws li, cupermounts, hlua hlau) thaum nyob ntawm UAVs (Aerial app) cia siab rauRoj hmab sab nraud Elastomer Raug Rho Tawm, Kos duab ntawm MIL-STD-STD-STD {{1} Cov Qauv, Cov Kev Kawm Xyuas Cov phooj ywg,}}}}), thiab cov ntaub ntawv kev lag luam.
General Txheej txheem cej luam ntawm Shock thiab Kev Co Kev Kho Mob Rho
Poob Siab thiab Kev Co Rho Tawm NruabTiv thaiv cov khoom siv rhiab-xws li Eo \/ Ir Sensors, gimbals, thiab hluav taws tswj cov kev ntxhov siab uas ua rau muaj kev ua tau zoo lossis ua rau tsis ua haujlwm. Kev poob siab yog qhov kev tshwm sim, piv txwv li, {} m dua {} m dua {4}} {{{5} {5. Ob leeg yog tswj hwm los ntawmMil-std -810Cov Qauv, nrog Txoj Kev 516.8 Ntsuas Shocks thiab Txoj Kev Siv 514.8 ntsuas kev co. Kev rho tawm hauv kev rho tawm ntawm lub zog hloov mus rau cov khoom tiv thaiv, ua kom muaj kev tiv thaiv (piv txwv li}. 5 MRAD rau RCWs) thiab ncua kev pabcuam.
Cov ntsiab cai ntawm kev cais
Kev rho tawm cov tshuab tsis sib thooj lossis tshem tawm lub zog hluav taws xob uas siv cov hau kev dhau los lossis cov txheej txheem nquag:
- Kev Rho Tawm: Kev ntseeg ntawm cov tshuab kho tshuab (piv txwv li, elastomers, springs) kom nqus lub zog ntawm damping lossis txhav. Cov ntaub ntawv viscoelastic, xws li cov roj hmab lossis silicone, hloov siab vibrational lub zog rau hauv tshav kub, thaum springs txo kev sib kis.
- Cov neeg cais tawm: Siv cov sensors thiab actuatators rau kev tiv thaiv kev deeg nyob rau hauv tiag tiag, feem ntau ua khub nrog cov ntawv thov sib tw hauv cov ntawv thov siab (piv txwv li ua ntej mus ua ntej). Txawm li cas los xij, cov thev naus laus zis nce ntxiv thiab tus nqi.
Cov Txheeb Ze Ntawm Kev Rho Tawm
- Elastomer mis nyuj: Roj hmab, silicone, lossis neoprene cores muab cov dame damping, muaj txiaj ntsig} hz ribrations thiab {}}} g poob siab. Lawv yog lub teeb yuag, raug nqi, thiab resilient ({{}} degree rau {}}} degree).
- Cupmounts: Interlocking metal cups encase an elastomeric core , offering multi-axis isolation for 50-100g shocks and >40 Hz dolrations. Compact ({5-10 cm) tab sis kim.
- Hlau Hlua Hlau Isolator: Stainless hlau cable nqus cov shocks ntawm kev txhuam, zoo tagnrho rau {} g poob siab thiab {} hz dogrations. Lawv muaj cov neeg tu ncua tab sis loj (10-20 cm, 1-5 kg).
- Damno Plyming: Cov plhaub zoo li cas (piv txwv li cov plhaub txhuas-sib xyaw) thiab gyro-stabilization (mems \/ pos) nqus hluav taws xob hauv sab hauv, txo qis sab nraud. Siv tau rau kev poob siab tab sis nyuaj thiab hwj chim-nyob.
Cov Ntawv Thov thiab Cov Qauv
Hauv kev tiv thaiv, kev rho tawm nruab nrab yog ua kom haum rau cov kev ntxhov siab tshwj xeeb. RCWS xav kom muaj kev poob siab relenuation rau kev sib ntaus, thaum UAVs ua ntej kev co damping rau them nyiaj ruaj khov. MIL-STD -810 Saib xyuas kev ntseeg tau hla ib puag ncig (}} degree, ntsev-std -167 chaw nyob naval deeg. Cov qauv tsis ntev los no qhia txog kev tsim kho hybrid, sib xyaw ua ke nrog cais tawm nrog cov tub rog ua haujlwm kom zoo rau cov tub rog txhim kho Aerospace, 2024.
RCWS: Kev Damping Hauv Tsev thiab Embedded Rho Tawm
Yuav Tsum Tau Ua Haujlwm
RCWS, zoo li Rafael's Samson thiab Leonardo's Hitrole, yog tsim rau thaj av lossis Naval kev sib ntaus, Mounting cov riam phom sib txawv. Lawv ntsib high-g poob siab los ntawm rab phom thiab tsawg-zaus vibrations (2-10 hz) los ntawm recoil lossis cov lus tsa suab. Thaum tswj hwm boresight kev tuav khaws cia yog qhov tseem ceeb rau kev tsom xam qhov tseeb, ib mais-std {}} (txoj kev 516.8). Harsh qhov chaw (piv txwv li, {{{{}} degree rau +70 degree, ntsev txau drive tsav kev sib cais kho cov tswv yim.
Tsim
RCWS ua ntej kev zom zaub mov hauv kev zom zaub mov thiab ua rau muaj kev cuam tshuam rau kev tswj hwm kev ua rau muaj kev phom sij thaum tsis muaj peev xwm nkag rau sab nraud:
- Damno Plyming: Raammed Pimbides (piv txwv li, alloys alloys, Composites alloys, Composites alloys, Composites) thiab Mems \/ Fam Gyro-Storilization nqus lub zog. Nrog iscoelastic txheej thiab gyroscopes, ua tiav qhov siab precision optical axis khaws cia. Qhov no txo qis sab nraud mount advernence, txhim kho durability.
- Embedded Mis Tawm: Cuppigs thiab cov hlua hlau cais tawm hauv cov hauv paus lossis chassis. Cupermounts feem ntau yog qhov zoo tshaj rau cov ntawv thov naval. Hlau hlua Isolators, txawm hais tias ntau zog, txhawb cov hluav taws xob hnyav rcws rcws nrog {{0} hz damping.
Tiam sis
RCWs nyiam cov qauv tsim, raws li pom nyob rau hauv cov neeg ua si tseem ceeb ntawm kev lag luam, kev cais tawm hauv kev lag luam sab hauv.
Ua Si: Roj Hmab Sab Nraud Elastomer Raug Rho Tawm
Yuav Tsum Tau Ua Haujlwm
Uavs, los ntawm kev ua lag luam DJI rau tub rog mq {{{{}} hz)}} hz)}}}} g) los ntawm tsaws lossis gusts. Payloads zoo li EO \/ IR cov koob yees duab lossis Lidar yuav tsum muaj kev ruaj khov zoo rau kev xav lossis hom phiaj. Cov kev txwv hnyav (piv txwv li, 0. {{} {}}}} Degree rau kev tub rog) cov kev xaiv luas).
Tsim
UAVS vam khom rau lwm cov roj hmab Elastomer Elastomer rau kev yooj yim thiab kev ua tau zoo:
- Elastomers Sab nraud: Roj hmab lossis silicone mount yog bolted ntawm payloads thiab airframes, damping {{dogrations nrog 97% rho tawm.
Kev sib piv: Poob siab me me rau cov av RCWS Vs. Uavs Gimbals

Poob siab thiab kev co cais tsim yog tsim kom muaj lub platform-cov kev xav tau tshwj xeeb. RCWs cia siab rau kev tawm tsam nrog kev zom zaub mov thiab catmounts, hlua hlau) los tswj cov hlua hlau) los tswj cov mob loj thiab cov kab mob sib ceeb, ua kom muaj kev sib cav sib ceg. Uavs haum sab nraud roj hmab Elastomer cais tawm rau lawv lub teeb ci, zoo nqi kev co damping, zoo tagnrho rau cov payload ruaj khov nyob ib puag ncig. Cov tswv yim no, siv tau los ntawm mil-std {4}}, phooj ywg tshawb fawb thiab cov ntaub ntawv kev lag luam, muaj kev cuam tshuam txog kev tiv thaiv thiab aerospace. Thaum Hybrid Kev rho tawm cov tshuab tawm, ua ke cov hau kev ruam thiab nquag, ob qho tib si RCWs thiab UVS tuaj yeem pom cov kev ua tau zoo, hloov mus rau lawv txoj hauv kev sib txawv.
