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 ukuma kwe-aerodynamic kwendiza, ukuvikela uhlelo lwe-antenna endaweni yangaphandle, nokwandisa lonke uhlelo. Impilo, ukuvikela ukunemba kobuso be-antenna kanye nendawo. Izinto zokukhiqiza zendabuko ngokuvamile amapuleti ensimbi namapuleti e-aluminium, anezinkinga eziningi, njengekhwalithi enkulu, ukumelana nokugqwala okuphansi, ubuchwepheshe bokucubungula okukodwa, kanye nokungakwazi ukwakha imikhiqizo enezimo eziyinkimbinkimbi kakhulu. Isicelo siye sabhekana nemikhawulo eminingi, futhi inani lezicelo liyehla. Njengezinto ezisebenza kahle kakhulu, izinto ze-FRP zingaqedwa ngokungeza ama-conductive fillers uma kudingeka i-conductivity. Amandla esakhiwo angaqedwa ngokuklama ama-stiffeners nokushintsha ubukhulu bendawo ngokwezidingo zamandla. Isimo singenziwa sibe yizimo ezahlukene ngokwezidingo, futhi simelana nokugqwala, silwa nokuguga, isisindo esincane, singaqedwa ngokubeka ngesandla, i-autoclave, i-RTM nezinye izinqubo ukuqinisekisa ukuthi i-radome ihlangabezana nezidingo zokusebenza kanye nokuphila kwenkonzo.
2. Isicelo ku-antenna yeselula yokuxhumana
Eminyakeni yamuva nje, ngentuthuko esheshayo yokuxhumana kweselula, inani lama-antenna eselula nalo likhuphuke kakhulu, kanti inani lama-radome asetshenziswa njengezingubo zokuzivikela zama-antenna eselula nalo likhuphuke kakhulu. Izinto ze-radome eselula kumele zibe nokuvuleka kwamagagasi, ukusebenza kwangaphandle kokulwa nokuguga, ukusebenza kokumelana nomoya kanye nokuvumelana kwe-Batch, njll. Ngaphezu kwalokho, impilo yayo yesevisi kumele ibe yinde ngokwanele, ngaphandle kwalokho izoletha ukuphazamiseka okukhulu ekufakweni nasekugcinweni, futhi inyuse izindleko. I-radome eselula ekhiqizwe esikhathini esidlule yenziwe kakhulu ngezinto ze-PVC, kodwa le nto ayimelani nokuguga, inokumelana okuncane komthwalo womoya, inokuphila okufushane kwesevisi, futhi isetshenziswa kancane kancane. Izinto zepulasitiki eziqiniswe ngefayibha yengilazi zinokuvuleka kwamagagasi okuhle, ikhono eliqinile lokulwa nokuguga ngaphandle, ukumelana nomoya okuhle, kanye nokuvumelana okuhle kwe-batch kusetshenziswa inqubo yokukhiqiza i-pultrusion. Impilo yesevisi ingaphezu kweminyaka engama-20. Ihlangabezana ngokugcwele nezidingo ze-radome eselula. Ithathe indawo ye-PVC kancane kancane. Ipulasitiki isibe ukukhetha kokuqala kwama-radome eselula. Ama-radome ahambayo eYurophu, e-United States nakwamanye amazwe avimbele ukusetshenziswa kwama-radome epulasitiki e-PVC, futhi wonke asebenzisa ama-radome epulasitiki aqiniswe ngefayibha yengilazi. Njengoba izidingo zezinto ze-radome eziphathwayo zithuthuka kakhulu ezweni lakithi, ijubane lokwenza ama-radome ahambayo enziwe ngezinto zepulasitiki eziqiniswe ngefayibha yengilazi esikhundleni sepulasitiki ye-PVC nalo liyashesha.
3. Isicelo ku-antenna yokwamukela isathelayithi
I-antenna yokwamukela isathelayithi iyithuluzi elibalulekile lesiteshi somhlaba sesathelayithi, ihlobene ngqo nekhwalithi yesignali yesathelayithi etholayo kanye nokuqina kwesistimu. Izidingo zezinto zama-antenna esathelayithi isisindo esincane, ukumelana nomoya okunamandla, ukulwa nokuguga, ukunemba okuphezulu, akukho ukuguquguquka, impilo yesevisi ende, ukumelana nokugqwala, kanye nezindawo ezikhanyayo eziklanywayo. Izinto zokukhiqiza zendabuko ngokuvamile amapuleti ensimbi namapuleti e-aluminium, akhiqizwa ubuchwepheshe bokunyathela. Ubukhulu ngokuvamile buncane, abumelani nokugqwala, futhi bunempilo yesevisi emfushane, ngokuvamile iminyaka emi-3 kuya kwemi-5 kuphela, futhi imikhawulo yokusetshenziswa kwayo iya ngokuya iba nkulu. Yamukela izinto ze-FRP futhi ikhiqizwa ngokuhambisana nenqubo yokubumba ye-SMC. Inokuqina kosayizi omuhle, isisindo esincane, ukulwa nokuguga, ukuhambisana okuhle kwebhetshi, ukumelana nomoya okunamandla, futhi ingaklama neziqinisi zokuqinisa ukuze ithuthukise amandla ngokwezidingo ezahlukene. Impilo yesevisi ingaphezu kweminyaka engama-20. , Ingaklanywa ukubeka i-mesh yensimbi nezinye izinto ukuze kufezwe umsebenzi wokwamukela isathelayithi, futhi ihlangabezane ngokugcwele nezidingo zokusetshenziswa maqondana nokusebenza kanye nobuchwepheshe. Manje ama-antenna e-satellite e-SMC asesetshenziswe ngobuningi obukhulu, umphumela muhle kakhulu, ngaphandle akukho ukulungiswa, umphumela wokwamukela muhle, futhi amathuba okusebenzisa nawo muhle kakhulu.
4. Ukusetshenziswa ku-antenna yesitimela
Isivinini sesitimela senyuswe okwesithupha. Isivinini sesitimela siyashesha futhi sishesha, futhi ukudluliswa kwesignali kumele kusheshe futhi kube nembambo. Ukudluliswa kwesignali kwenziwa nge-antenna, ngakho-ke ithonya le-radome ekudlulisweni kwesignali lihlobene ngqo nokudluliswa kolwazi. I-radome yama-antenna esitimela e-FRP ibilokhu isetshenziswa isikhathi eside. Ngaphezu kwalokho, iziteshi zokuxhumana eziphathwayo azikwazi ukusungulwa olwandle, ngakho-ke imishini yokuxhumana ephathwayo ayikwazi ukusetshenziswa. I-radome ye-antenna kumele imelane nokuguguleka kwesimo sezulu sasolwandle isikhathi eside. Izinto ezivamile azikwazi ukuhlangabezana nezidingo. Izici zokusebenza ziboniswe ngezinga elikhulu okwamanje.
5. Ukusetshenziswa ku-core eqinisiwe yekhebula le-fiber optic
I-Aramid fiber reinforced fiber reinforced core (KFRP) uhlobo olusha lwe-non-metallic fiber reinforced core esebenza kahle kakhulu, esetshenziswa kabanzi kumanethiwekhi okufinyelela. Umkhiqizo unezici ezilandelayo:
1. Ilula futhi inamandla aphezulu: I-core yekhebula eliqinisiwe le-aramid fiber inobukhulu obuphansi namandla aphezulu, futhi amandla ayo noma i-modulus idlula kakhulu lawo e-core yekhebula eliqinisiwe lensimbi kanye ne-glass fiber;
2. Ukwanda okuphansi: Ingqikithi eqinisiwe yekhebula le-optical eliqinisiwe le-aramid fiber ine-coefficient yokwanda eqondile ephansi kunentambo yensimbi kanye nengqikithi eqinisiwe yekhebula le-optical eliqinisiwe le-glass fiber ebangeni elibanzi lokushisa;
3. Ukumelana nokushayisana nokuphazamiseka: I-aramid fiber eqiniswe ngentambo ye-fiber optic eqinisiwe ayigcini nje ngokuba namandla okushibilika aphezulu kakhulu (≥1700Mpa), kodwa futhi inomthelela ekumelaneni nokuphazamiseka kokuphazamiseka. Ngisho noma iphuka, isengagcina amandla okushibilika angaba ngu-1300Mpa ；
4. Ukuguquguquka okuhle: I-core yekhebula le-optical eliqiniswe ngefayibha ye-aramid inokwakheka okuthambile futhi kulula ukugoba. Ububanzi bayo obuncane bokugoba buphindwe kabili kune-diameter;
5. Ikhebula le-optical langaphakathi linesakhiwo esincane, ukubukeka okuhle kanye nokusebenza okuhle kakhulu kokugoba, okufanelekela kakhulu ukuxhuma izintambo ezindaweni eziyinkimbinkimbi zangaphakathi. (Umthombo: Ulwazi Oluhlanganisiwe).
