2.1 Ginshiƙin Bistable Ultrathin Composite

Tsarin tsakiya shine ginshiƙin bistable da aka ƙera daga laminates na polymer mai ƙarfafa fiber carbon (CFRP). Bistability ɗinsa yana ba shi damar samun tsayayyen daidaitattun tsari guda biyu: yanayi mai matuƙar naɗewa/adananne da kuma madaidaiciyar yanayi/faɗaɗa. Canji tsakanin jihohi ana samun shi ta hanyar sakin makamashin ƙwanƙwasa da aka adana, yana ba da damar faɗaɗawa ta kai ba tare da injuna ko rikitattun hinge ba. Bayanin da ba a taɓa gani ba (<250 µm) yana rage girman adananne da nauyi, wanda ke da mahimmanci ga CubeSats.

2.2 Haɗawa da Na'urorin Lantarki Masu Sassauƙa

Ana haɗa na'urorin lantarki masu sassauƙa a kan saman ginshiƙi. Waɗannan sun haɗa da na'urori masu auna ƙwanƙwasa don sa ido kan ƙwanƙwasa/girgiza, da kuma alamun watsawa don wutar lantarki da watsa bayanai daga motar CubeSat zuwa abin da aka ɗora a ƙarshen ginshiƙi (misali, na'urar aunawa ko eriya). Wannan haɗin yana magance ƙalubalen sa ido kan yanayin faɗaɗawa akan irin waɗannan siraran tsare-tsare masu nakasa ba tare da ƙara nauyi mai yawa ko canza halayen injiniya ba, wanda shine rashin amfani na hanyoyin tuntuɓar gargajiya ko kyamarori na waje.

3. Cikakkun Bayanai na Fasaha & Tsarin Lissafi

Ana iya ƙirƙira halayen bistable da yanayin faɗaɗawa la'akari da ma'auni na ƙirƙira na laminate da ƙa'idodin makamashi. Makamashin ƙwanƙwasa ($U$) da aka adana a cikin tsarin naɗewa aiki ne na taurin lanƙwasa ($D$) na kayan da kuma lanƙwasa ($\kappa$):

$U = \frac{1}{2} \int D \kappa^2 \, ds$

Bayan sakin, wannan makamashin yana motsa faɗaɗawar. Ana iya ƙididdige yanayin motsi ta hanyar daidaita ma'auni mai daidaita ƙarfin inertia, damping, da ƙarfin roba. Don ƙirar 1D mai sauƙi na ƙarshen faɗaɗawa, ana iya bayyana ma'aunin motsi kamar haka:

$m\ddot{x} + c\dot{x} + kx = F_{elastic}(t)$

inda $m$ shine ingantaccen nauyi, $c$ shine damping, $k$ shine taurin, $x$ shine matsarwa, kuma $F_{elastic}(t)$ shine ƙarfin motsa jiki mai canzawa lokaci wanda aka samo daga sakin makamashin ƙwanƙwasa. Ingantattun na'urori masu auna ƙwanƙwasa masu sassauƙa suna ba da bayanan ainihin lokaci don tabbatarwa da inganta irin waɗannan ƙira.

4. Sakamakon Gwaji & Aiki

Samfurin ginshiƙi ya yi nasara ya nuna ayyuka da yawa a cikin gwaje-gwajen dakin gwaje-gwaje kuma an haɗa shi azaman kayan aikin jirgin sama a cikin CubeSat 3U don nunin sararin samaniya.

Faɗaɗawa & Sa ido kan Yanayin Motsi: Ingantattun ma'aunin ƙwanƙwasa masu sassauƙa sun ba da bayanan ainihin lokaci yayin faɗaɗawa, suna ɗaukar yanayin motsi na wucin gadi da girgiza bayan faɗaɗawa. Wannan bayanin yana da mahimmanci don tabbatar da amincin faɗaɗawa da fahimtar halayen tsarin sararin samaniya.

Watsa Wutar Lantarki & Bayanai: Ginshiƙin ya ba da wutar lantarki da alamun watsa bayanai daga jikin CubeSat zuwa abin da aka ɗora a ƙarshensa ta hanyar haɗaɗɗun da'irori masu sassauƙa, yana tabbatar da matsayin tsari/ayyuka biyu.

Bayanin Jadawali (Ra'ayi): Jadawali zai nuna: 1) Ƙwanƙwasa vs. Lokaci yayin faɗaɗawa, yana nuna kololuwa mai kaifi yayin tsalle zuwa yanayin madaidaiciya, sannan kuma raɗaɗi masu damping. 2) Ingantaccen Sigina kwatanta ingancin watsa bayanai (misali, ƙimar kuskuren bit) ta hanyar da'irori masu sassauƙa da hanyar haɗin waya na gargajiya, yana nuna ƙaramin lalacewa. 3) Hotunan Jerin Faɗaɗawa suna nuna yanayin naɗewa, tsakiyar faɗaɗawa, da cikakken yanayin faɗaɗawa.

5. Tsarin Bincike & Nazarin Lamari

Nazarin Lamari: Ginshiƙin Eriya Mai Faɗaɗawa don Sadarwar CubeSat.

Yanayi: CubeSat 6U yana buƙatar ginshiƙi mai faɗaɗawa na mita 1 don sanya eriya UHF nesa da jikin tauraron dan adam don rage tsangwama.

Hanyar Gargajiya: Yi amfani da ginshiƙin na'ura mai motsi ko na'urar baka. Wannan yana ƙara hanyoyin (injuna, kulle-kulle), nauyi, da rikitarwa. Yana ba da tallafin tsari kawai; ana buƙatar keɓantaccen igiyoyin waya masu nauyi don eriya.

Hanyar da aka Tsara Mai Ayyuka Da Yawa: Yi amfani da ginshiƙin bistable ultrathin composite tare da haɗaɗɗun na'urorin lantarki masu sassauƙa.

1. Ƙira: An ƙera ginshiƙin bistable CFRP mai tsayin mita 1, kauri 200 µm. An zana alamun tagulla masu sassauƙa a kan samansa don samar da layin watsawa wanda ke haɗa rediyon tauraron dan adam zuwa ɓangaren eriya a ƙarshen.
2. Haɗawa: An naɗe ginshiƙin kuma an adana shi a cikin ƙaramin girma a waje na tauraron dan adam. An haɗa ɓangaren eriya (eriya mai sassauƙa da aka buga) a ƙarshen.
3. Aiki: A kan umarni, sauƙaƙan hanyar saki yana 'yantar da ginshiƙi. Yana faɗaɗa kansa. Layin watsawa mai sassauƙa nan da nan ya zama mai aiki. Ingantattun na'urori masu auna ƙwanƙwasa suna tabbatar da cikakken faɗaɗawa kuma suna sa ido kan girgizar ginshiƙi wanda zai iya shafar ingancin sigina.
4. Sakamako: An adana nauyi da girma >50% idan aka kwatanta da hanyar gargajiya. Tsarin ya fi aminci (ƙananan sassa masu motsi) kuma yana ba da sa ido kan lafiya da aka gina.

8. Binciken Ƙwararru & Fahimta

Fahimta ta Tsakiya: Wannan takarda ba kawai game da sabon ginshiƙi ba ne; shi ne tsarin dabarun haɗuwa dole na injiniyoyin tsari da rarraba na'urorin lantarki a cikin tsarin sararin samaniya. Marubutan sun gano daidai cewa makomar ƙananan tauraron dan adam ba ta taƙaita kowane ɓangare ba, amma a cikin ƙaddamar da yawan aiki a kowace gram da santimita cubic. Maganinsu—haɗa kyawawan injiniyoyin bistable composites tare da yuwuwar canji na na'urorin lantarki masu sassauƙa—yana kai hari ga ainihin rashin ingancin ƙirar jirgin sama na gargajiya: rarraba tsari, wutar lantarki, da tsarin bayanai.

Kwararar Ma'ana: Hujjar tana da ban sha'awa. Ya fara da matsin lamba maras musantawa na ƙuntatawa na CubeSat, yana sukar gazawar hanyoyin sa ido da suka wanzu (na gani ba shi da aminci, hanyoyin tuntuɓar suna kutsawa), kuma ya sanya na'urorin lantarki masu sassauƙa a matsayin kawai mafita mai yuwuwa, mara kutsawa. Tsalle na ma'ana daga "sa ido" zuwa "ayyuka da yawa" (watsa wutar lantarki/bayanai) shine inda ra'ayin ya canza daga haɓaka ƙari zuwa canjin tsari. Nunin kayan aikin jirgin sama a cikin CubeSat 3U shine mahimmin tabbacin ra'ayi wanda ya ɗaukaka shi daga ka'idar zuwa gaskiyar kusa.

Ƙarfi & Kurakurai: Ƙarfinsa shine tsarinsa na tsarin gaba ɗaya. Yana kama da yanayin terrestrial IoT da fasahar sawa, inda ake saka na'urori masu auna da masu gudanarwa cikin kayan, kamar yadda aka gani a cikin bincike daga cibiyoyi kamar MIT Media Lab da Ƙungiyar Binciken Bao ta Stanford. Duk da haka, aibin takardar—ko fiye da haka, tambayarta da ba a amsa ba—ya ta'allaka ne a cikin tasirin yanayin sararin samaniya na dogon lokaci. Yayin da aka gwada na'urorin lantarki masu sassauƙa don dorewa a Duniya, aikin su a ƙarƙashin dogon lokaci ga iskar oxygen atomic, radiation UV, da yanayin zafi mai tsananin a sararin samaniya ba a rubuta shi sosai. Shin ma'aunin polymer zai yi tauri? Shin za a sami ɓarkewar fim mai bakin ciki? Marubutan sun dogara da kariyar composite, amma wannan yana buƙatar tabbaci a fili. Bugu da ƙari, yuwuwar watsa wutar lantarki akan dogayen ginshiƙai (> 'yan mita) ta amfani da alamun sirara masu sassauƙa na iya fuskantar ƙalubalen juriya da asarar sigina da ba a magance a nan ba.

Fahimta Mai Aiki: Ga 'yan wasan masana'antu, abin da za a ɗauka a bayyane yake: saka hannun jari a cikin ƙungiyoyi masu fannoni daban-daban waɗanda ke haɗa kimiyyar kayan composite, ƙirar na'urorin lantarki masu sassauƙa, da injiniyan tsarin jirgin sama. Mataki na gaba ba kawai gina ingantaccen ginshiƙi ba ne, amma haɓaka daidaitattun hanyoyin da suka cancanta don ƙirƙira waɗannan laminates masu ayyuka da yawa—ƙalubali mai kama da ƙirƙirar "allurar da'ira mai daraja ta sararin samaniya" wanda kuma shine tsarin farko.
