1. Isicelo ku-radome ye-radar yokuxhumana
I-radome iyisakhiwo esisebenzayo esihlanganisa ukusebenza kukagesi, amandla esakhiwo, ukuqina, ukuma kwe-aerodynamic kanye nezidingo ezikhethekile zokusebenza.Umsebenzi wayo oyinhloko ukuthuthukisa isimo se-aerodynamic sendiza, ukuvikela uhlelo lwe-antenna endaweni yangaphandle, nokwandisa lonke uhlelo.Impilo, vikela ukunemba kwendawo ye-antenna nendawo.Izinto zokukhiqiza zendabuko ngokuvamile amapuleti ensimbi namapuleti e-aluminium, anokusilela okuningi, njengekhwalithi enkulu, ukumelana nokugqwala okuphansi, ubuchwepheshe bokucutshungulwa okukodwa, kanye nokungakwazi ukwenza imikhiqizo enobumo obuyinkimbinkimbi ngokweqile.Isicelo besingaphansi kwemikhawulo eminingi, futhi inani lezicelo liyancipha.Njengempahla esebenza kahle kakhulu, izinto ze-FRP zingaqedwa ngokungeza ama-conductivity fillers uma kudingeka.Amandla esakhiwo angaqedwa ngokuklama ama-stiffeners futhi endaweni ashintshe ukujiya ngokuvumelana nezidingo zamandla.Umumo ungenziwa ubujamo obuhlukene ngokwezidingo, futhi awukwazi ukugqwala, Anti-ukuguga, isisindo esilula, ungagcwaliswa ngokubeka izandla, i-autoclave, i-RTM nezinye izinqubo zokuqinisekisa ukuthi i-radome ihlangabezana nezidingo ukusebenza kanye nempilo yesevisi.
2. Isicelo ku-antenna yeselula yokuxhumana
Eminyakeni yamuva, ngokuthuthuka okusheshayo kokuxhumana kweselula, inani lezimpondo ezihambayo nalo liye landa kakhulu, futhi inani le-radome elisetshenziswa njengezingubo zokuvikela izimpondo ezihambayo nalo liye landa kakhulu.Impahla ye-radome ephathwayo kufanele ibe nokungena kwamagagasi, ukusebenza kwangaphandle kokulwa nokuguga, ukusebenza kokumelana nomoya kanye nokuvumelana kwe-Batch, njll. Ngaphezu kwalokho, impilo yayo yesevisi kufanele ibe yinde ngokwanele, ngaphandle kwalokho izoletha ukuphazamiseka okukhulu ekufakeni nasekugcinweni kwayo, futhi kwandise. izindleko.I-radome ephathwayo ekhiqizwa esikhathini esidlule ngokuvamile yenziwe ngezinto ze-PVC, kodwa le nto ayimelani nokuguga, inokumelana nomthwalo womoya omubi, inokuphila okufushane kwesevisi, futhi isetshenziswa kancane kancane.Izinto zepulasitiki eziqinisiwe ze-glass fiber zikwazi ukungena kahle kwamagagasi, ikhono eliqinile langaphandle lokulwa nokuguga, ukumelana nomoya omuhle, nokungaguquguquki okuhle kwe-batch kusetshenziswa inqubo yokukhiqiza i-pultrusion.Impilo yesevisi ingaphezu kweminyaka engama-20.Ihlangabezana ngokugcwele nezidingo ze-radome yeselula.Kancane kancane ithathe indawo yePVC Plastic isibe yisinqumo sokuqala sama-radome eselula.Amaradomu eselula eYurophu, e-United States nakwamanye amazwe avimbele ukusetshenziswa kwama-radome epulasitiki e-PVC, futhi wonke asebenzisa ama-radome epulasitiki aqiniswe ngengilazi.Ngokuthuthuka okuqhubekayo kwezidingo zezinto ezisetshenziswayo ze-radome ephathwayo ezweni lami, ijubane lokwenza ama-radome eselula enziwe ngezinto zepulasitiki eziqiniswe nge-glass fiber esikhundleni samapulasitiki e-PVC nawo ayakhula.
3. Isicelo sesathelayithi eyamukela uthi
Isathelayithi eyamukela i-antenna iyisisetshenziswa esibalulekile sesiteshi saphansi sesathelayithi, ihlobene ngokuqondile nekhwalithi yokwamukela isignali yesathelayithi kanye nokuzinza kwesistimu.Izidingo zezinto ezibonakalayo zezimpondo zesathelayithi yisisindo esilula, ukumelana nomoya onamandla, ukulwa nokuguga, ukunemba kobukhulu obuphezulu, akukho ukuguquguquka, impilo ende yesevisi, ukumelana nokugqwala, kanye nezindawo ezibukekayo ezibukekayo.Izinto zokukhiqiza zendabuko ngokuvamile amapuleti ensimbi namapuleti e-aluminium, akhiqizwa ubuchwepheshe bokugxiviza.Ugqinsi luvamise ukuba mncane, alukwazi ukumelana nokugqwala, futhi lunempilo yesevisi emfushane, ngokuvamile iminyaka emi-3 ukuya kwemi-5 kuphela, futhi ukulinganiselwa kokusetshenziswa kwalo kuya ngokuya kuba kukhudlwana.Yamukela impahla ye-FRP futhi ikhiqizwa ngokuhambisana nenqubo yokubumba ye-SMC.Inokuqina okuhle kosayizi, isisindo esilula, anti-ukuguga, ukungaguquki okuhle kwe-batch, ukumelana komoya onamandla, futhi ingaklama ama-stiffeners ukuthuthukisa amandla ngokuya ngezidingo ezahlukahlukene.Impilo yesevisi ingaphezu kweminyaka engama-20., Ingaklanywa ukubeka insimbi yensimbi nezinye izinto ukuze kuzuzwe umsebenzi wokwamukela i-satellite, futhi ihlangabezane ngokugcwele nezidingo zokusetshenziswa mayelana nokusebenza nobuchwepheshe.Manje ama-antenna wesathelayithi e-SMC asetshenziswe ngobuningi, umphumela muhle kakhulu, ngaphandle awukhathaleli, umphumela wokwamukela muhle, futhi ithemba lohlelo lokusebenza nalo lihle kakhulu.
4. Isicelo ku-antenna kaloliwe
Isivinini sikaloliwe senyuswe okwesithupha.Isivinini sesitimela siya ngokushesha futhi ngokushesha, futhi ukudluliswa kwesignali kufanele kusheshe futhi kunembile.Ukudluliselwa kwesignali kwenziwa nge-antenna, ngakho-ke umthelela we-radome ekudlulisweni kwesignali uhlobene ngokuqondile nokudluliswa kolwazi.I-radome yezimpondo zikaloliwe ze-FRP isinesikhathi eside isetshenziswa.Ukwengeza, iziteshi eziyisisekelo zokuxhumana ngomakhalekhukhwini azikwazi ukusungulwa olwandle, ngakho-ke imishini yokuxhumana ephathwayo ayikwazi ukusetshenziswa.I-antenna radome kumele imelane nokuguguleka kwesimo sezulu sasolwandle isikhathi eside.Izinto ezijwayelekile azikwazi ukuhlangabezana nezidingo.Izici zokusebenza zivezwe ngokwezinga elikhulu ngalesi sikhathi.
5. Isicelo kuntambo ye-fiber optic ewumgogodla oqinisiwe
I-Aramid fibre reinforced fibre reinforced core (KFRP) iwuhlobo olusha lwe-non-metallic fiber reinforced core esebenza kakhulu, esetshenziswa kakhulu kumanethiwekhi okufinyelela.Umkhiqizo unezici ezilandelayo:
1. I-lightweight namandla aphezulu: I-aramid fibre optical cable core eqinisiwe inokuminyana okuphansi namandla aphezulu, futhi amandla ayo noma i-modulus idlula kude izintambo zensimbi ne-glass fibre optical cable cores eqinisiwe;
2. Ukunwetshwa okuphansi: I-aramid fibre eqinisiwe yekhebula le-optical eqinisiwe inecoefficient ephansi yokunwetshwa komugqa kunentambo yensimbi ne-glass fibre eqiniswe intambo yokubona eqinisiwe ebangeni lokushisa elibanzi;
3. Ukumelana nomthelela kanye nokumelana nokuphuka: I-aramid fiber reinforced fibre optic cable reinforced core ayigcini nje ngokuba namandla aphezulu aphezulu (≥1700Mpa), kodwa futhi inomthelela ukumelana nokumelana nokuphuka.Ngisho noma kwenzeka iphuka, isengakwazi ukugcina amandla aqinile angaba ngu-1300Mpa;
4. Ukuvumelana nezimo okuhle: I-aramid fibre optical core eqinisiwe inokwakheka okuthambile futhi kulula ukugoba.Ubuncane be-diameter egobayo buphindwe izikhathi ezingu-24 kuphela ububanzi;
5. Ikhebula le-optical langaphakathi linesakhiwo esihlangene, ukubukeka okuhle nokusebenza okuhle kakhulu kokugoba, okulungele ikakhulukazi izintambo ezindaweni eziyinkimbinkimbi zasendlini.(Umthombo: Ulwazi Oluhlanganisiwe).
