Kev poob phaus yam tsis tau poob vaj huam sib luag nruj
Cov nkoj hauv hiav txwv, cov tsheb ciav hlau, tsheb npav, thiab cov tsheb thauj khoom txhua tus muaj - thaj chaw loj hauv pem teb, phab ntsa, qab nthab, thiab cov vaj huam sib luag. Thaum cov khoom no yog tsim los ntawm plywood, khoom fiberglass laminate, los yog steel ntawv, vaj huam sib luag hnyav nce sai li thickness nce.
Ib lub vaj huam sib luag honeycomb siv cov qauv sandwich es tsis yog cov qauv tsim. Cov nplooj ntawv nyias nyias nqa cov tensile thiab compressive loads, thaum lub honeycomb core cais cov tawv nqaij thiab hloov shear loads los ntawm lub vaj huam sib luag thickness. Qhov kev npaj no ua rau kom bending txhav yam tsis tas yuav tsum muaj lub hauv paus ruaj khov.
Piv txwv li, 20 hli honeycomb sandwich vaj huam sib luag tuaj yeem ua tiav qhov flexural nruj dua li cov khoom laminate ntawm qhov hnyav zoo sib xws vim tias cov khoom thauj -cov tawv nqaij yog nyob deb ntawm qhov nruab nrab ntawm qhov nruab nrab.
Yuav Ua Li Cas Honeycomb Sandwich Vaj Huam Sib Luag Ua Haujlwm
Lub vaj huam sib luag honeycomb muaj peb txheej txheej txheej:
- Sab saum toj daim ntawv
- Honeycomb tub ntxhais
- Hauv qab daim ntawv
Thaum lub vaj huam sib luag ntsib kev khoov loads, daim tawv nqaij sab sauv nkag mus rau hauv compression thaum cov tawv nqaij qis nkag mus rau qhov nro. Lub honeycomb core tiv thaiv cov tawv nqaij los ntawm kev txav mus rau ib leeg thiab hloov cov quab yuam ntawm lawv.
Tsis zoo li ua npuas ncauj cores uas vam khom cov khoom ntim tas mus li, cov tub ntxhais honeycomb siv cov qauv cellular tsim los ntawm kev sib tshuam hexagonal hlwb. Cov hlwb khoob txo cov khoom siv thaum tswj vaj huam sib luag thickness.
Qhov kev thauj khoom no-hloov tshuab tso cai rau lub vaj huam sib luag los txhawb nqa cov khoom xa tawm thoob plaws hauv pem teb, bulkheads, thiab cov qauv sab hauv thaum txo qhov loj ntawm tag nrho.
Cov khoom siv tseem ceeb siv nyob rau hauv Marine thiab tsheb thauj mus los
Cov chaw ua haujlwm sib txawv xav tau cov ntaub ntawv sib txawv honeycomb core.
Polypropylene (PP) Honeycomb
PP honeycomb cores yog tsim los ntawm cov ntawv thermoplastic polypropylene welded rau hauv cov qauv ntawm tes.
Cov khoom siv tsis nqus dej thiab feem ntau yog siv rau hauv ferry interiors, tsheb pem teb, caravan panels, thiab tsheb lub cev cov qauv uas yuav tsum tau ya raws.
Aluminium Honeycomb
Aluminium honeycomb yog tsim los ntawm nyias aluminium ntawv ci sib koom ua ke rau hauv hexagonal hlwb.
Cov tub ntxhais hlau ua kom muaj zog dua compressive thiab feem ntau yog muab tso rau hauv lub tsheb ciav hlau sab hauv, cov rooj tog zaum hauv hiav txwv, cov khoom siv vaj tse, thiab cov txheej txheem sib faib qhov twg siab dua - load kuj yuav tsum tau.
Aramid Honeycomb
Aramid honeycomb yog tsim los ntawm phenolic resin impregnated aramid ntawv.
Cov khoom siv feem ntau tau teev tseg rau aerospace thiab siab -kev ua haujlwm kev thauj mus los uas yuav tsum tau txo qhov hnyav dua li cov uas pom hauv daim ntawv thov tsheb lag luam.
Cov xwm txheej ua haujlwm Marine
Cov qauv hauv hiav txwv raug cuam tshuam rau cov tshuaj tsuag ntsev, cov av noo ntawm kev caij tsheb kauj vab, thiab rov ua dua kev co los ntawm cov cav thiab yoj cuam tshuam.
Nyob rau hauv cov cheeb tsam no, vaj huam sib luag tsis ua hauj lwm feem ntau tshwm sim los ntawm
Daim tawv nqaij - mus rau - core delamination
Dej nkag los ntawm cov npoo puas
Core crushing nyob rau hauv concentrated loads
Fastener rub- tawm ntawm qhov chaw mounting
Txhawm rau txo cov kev pheej hmoo no, cov vaj huam sib luag honeycomb feem ntau yog nruab nrog cov npoo sib khi, cov hlua txuas ntxiv, thiab cov ntsiab lus txuas txuas. Cov cheeb tsam uas txhawb nqa cov khoom siv thauj khoom feem ntau tau txais kev txhawb zog hauv zos los yog cov khoom siv sib xyaw kom faib cov zog muaj zog rau hauv cov qauv vaj huam sib luag.
Kev siv tsheb thauj mus los
Hauv kev thauj mus los, cov vaj huam sib luag honeycomb feem ntau yog sib xyaw ua ke rau hauv cov khoom tsis yog- cov txheej txheem tseem ceeb.
Cov piv txwv uas muaj xws li:
Railway interiors
Panels raug txiav, machined, thiab khi rau hauv pem teb systems, nra racks, qab nthab modules, thiab phab ntsa partitions. Cov khoom siv qis qis txo qhov hnyav ntawm txhua lub tsheb thauj mus los thiab txo lub zog noj thaum lub sijhawm nrawm.
Tsheb thiab Trailer Lub Cev
Honeycomb panels hloov plywood thiab steel ntawv nyob rau hauv sab phab ntsa, ru tsev, thiab pem teb sib dhos. Qhov txo qis hauv qhov hnyav ntawm cov qauv ua kom muaj peev xwm them taus thaum tswj vaj huam sib luag thickness.
Bus thiab Coach interiors
Cov neeg tsim khoom nruab cov sandwich panels hauv pem teb platforms, qab nthab modules, kev pabcuam vaj huam sib luag, thiab sab hauv partitions. Lub cellular core pab tswj lub vaj huam sib luag rigidity nyob rau hauv loj unsupported spans.
Kev xav txog kev teeb tsa
Honeycomb panels tsis tuaj yeem ntsia tau zoo ib yam li cov boards.
Mechanical fasteners xav tau kev txhawb zog vim hais tias cov tub ntxhais ntawm tes muab txwv rub- tawm tsis kam. Cov txheej txheem installation feem ntau suav nrog:
- Structural adhesive bonding
- Embedded aluminium inserts
- Ntug ncej reinforcement
- Los ntawm -bolted mounting cov ntsiab lus
Thaum qhib qhov rais, hatches, lossis cov cuab yeej raug muab tso rau hauv lub vaj huam sib luag, cov tub ntxhais uas raug kaw feem ntau raug kaw kom tsis txhob muaj dej nkag thiab kis tau.
Kev xaiv cov khoom nyob ntawm Load Case
Tsis muaj ib lub vaj huam sib luag honeycomb configuration yog haum rau txhua daim ntawv thov marine thiab tsheb thauj mus los.
Kev xaiv vaj huam sib luag feem ntau yog txiav txim los ntawm:
- Ntev ntev
- Tsim load
- Cov kev cai cuam tshuam
- Cov kev xav tau ntawm hluav taws kub
- Moisture raug tej yam kev mob
- Txoj kev txuas
Lub ferry qab nthab vaj huam sib luag, piv txwv li, tuaj yeem ua qhov tseem ceeb ntawm qhov hnyav thiab kev tiv thaiv corrosion, thaum lub vaj huam sib luag hauv pem teb yuav xav tau ntau dua compressive zog thiab puas ntsoog.
Kev nkag siab txog kev thauj khoom, ib puag ncig kev ua haujlwm, thiab txoj kev sib txuas yog qhov tseem ceeb ua ntej xaiv cov khoom siv honeycomb core thiab kev teeb tsa ntawm daim tawv nqaij.
HolyCore Honeycomb Core Solutions
HolyCore tsim cov khoom siv honeycomb core siv hauv cov khoom sib xyaw ua ke rau kev thauj mus los thiab kev siv dej hiav txwv. Core configurations tuaj yeem xaiv raws li vaj huam sib luag thickness, cell loj, cov khoom siv ntawm daim tawv nqaij, thiab cov kev xav tau ntawm kev thauj khoom.
Lub honeycomb core ua haujlwm raws li cov shear-hloov txheej hauv cov qauv qhaub cij, tso cai rau cov vaj huam sib luag kom muaj qhov tuab thaum txo cov khoom loj. Nyob ntawm daim ntawv thov, cov tub ntxhais tuaj yeem ua ke nrog fiberglass, aluminium, thermoplastic, lossis lwm yam khoom siv los tsim cov vaj huam sib luag tiav.
