Kulesi sifundo, i-Stainless steel coil tube, ukwakheka kwe-torsion kanye ne-compression springs ye-wing folding mechanism esetshenziswa ku-rocket kubhekwa njengenkinga yokwenza ngcono. Ngemva kokuba i-rocket ishiye i-launch tube, amaphiko avaliwe kumele avulwe futhi aqiniswe isikhathi esithile. Inhloso yalolu cwaningo kwakuwukukhulisa amandla agcinwe eziphethwini ukuze amaphiko akwazi ukusebenza ngesikhathi esifushane kakhulu. Kulesi simo, i-equation yamandla kuzo zombili izincwadi ichazwe njengomsebenzi oyinhloko enqubweni yokwenza ngcono. Ububanzi bentambo, ububanzi be-coil, inani lama-coil, kanye namapharamitha okuphambuka adingekayo ekwakhiweni kwentwasahlobo kuchazwe njengezinguquko zokwenza ngcono. Kunemikhawulo yejiyometri eziguquguquki ngenxa yobukhulu bendlela, kanye nemikhawulo kusici sokuphepha ngenxa yomthwalo othwalwa yiziphethri. I-algorithm yezinyosi zezinyosi (BA) yasetshenziswa ukuxazulula le nkinga yokwenza ngcono nokwenza umklamo wentwasahlobo. Amanani wamandla atholwe nge-BA aphakeme kunalawo atholwe ezifundweni zangaphambilini ze-Design of Experiments (DOE). Iziphethri kanye nezindlela eziklanywe kusetshenziswa amapharamitha atholwe ekwenzeni ngcono kwaqala ukuhlaziywa ohlelweni lwe-ADAMS. Ngemva kwalokho, kwenziwa izivivinyo zokuhlola ngokuhlanganisa iziphethu ezenziwe zibe yizindlela zangempela. Ngenxa yokuhlolwa, kwabonakala ukuthi amaphiko avuleka ngemva kwama-millisecond angaba ngu-90. Leli nani lingaphansi kakhulu komgomo wephrojekthi wama-millisecond angu-200. Ngaphezu kwalokho, umehluko phakathi kwemiphumela yokuhlaziya kanye neyokuhlola u-16 ms kuphela.
Ezimotweni zezindiza nezasolwandle, izindlela zokugoqa ishubhu le-coil yensimbi engagqwali zibalulekile. Lezi zinhlelo zisetshenziswa ekuguqulweni nasekuguqulweni kwezindiza ukuthuthukisa ukusebenza kwendiza nokulawula. Kuye ngemodi yokundiza, amaphiko ayagoqa futhi avuleke ngendlela ehlukile ukunciphisa umthelela we-aerodynamic1. Lesi simo singaqhathaniswa nokunyakaza kwamaphiko ezinye zezinyoni nezinambuzane ngesikhathi sokundiza nokuntywila kwansuku zonke. Ngokufanayo, ama-glider ayagoqa futhi avuleke ezindaweni ezingaphansi komhlaba ukuze kuncishiswe imiphumela ye-hydrodynamic futhi kwandiswe ukuphathwa3. Enye injongo yalezi zindlela ukunikeza izinzuzo zevolumu ezinhlelweni ezifana nokugoqa i-propeller yendiza enophephela emhlane 4 yokugcina nokuthutha. Amaphiko erokhethi nawo ayagoqa phansi ukuze kuncishiswe isikhala sokugcina. Ngakho-ke, imicibisholo eminingi ingafakwa endaweni encane yesiqalisi 5. Izingxenye ezisetshenziswa ngempumelelo ekugoqeni nasekuvulekeni zivame ukuba yizipringi. Ngesikhathi sokugoqa, amandla agcinwa kuwo futhi akhishwe ngesikhathi sokugoqa. Ngenxa yesakhiwo sawo esiguquguqukayo, amandla agciniwe nakhululwayo ayalingana. Intwasahlobo yenzelwe kakhulu uhlelo, futhi lo mklamo uletha inkinga yokwenza ngcono6. Ngoba nakuba ihlanganisa izinto ezihlukahlukene ezifana nobubanzi bentambo, ububanzi bekhoyili, inani lokujika, i-engeli ye-helix kanye nohlobo lwezinto zokwakha, kukhona nezindinganiso ezifana nobunzima, ivolumu, ukusatshalaliswa kokucindezeleka okuncane noma ukutholakala kwamandla aphezulu7.
Lolu cwaningo lucacisa ukwakheka kanye nokwenza ngcono kweziphethu zezindlela zokugoqa amaphiko ezisetshenziswa ezinhlelweni zamarokhethi. Njengoba zingaphakathi kwepayipi lokuqalisa ngaphambi kokundiza, amaphiko ahlala egoqekile ebusweni berokhethi, futhi ngemva kokuphuma epayipini lokuqalisa, avuleka isikhathi esithile futhi aqhubeke ecindezelwe phezulu. Le nqubo ibalulekile ekusebenzeni kahle kwerokhethi. Endleleni yokugoqa ethuthukisiwe, ukuvulwa kwamaphiko kwenziwa ngeziphethu ze-torsion, kanti ukukhiya kwenziwa ngeziphethu zokucindezela. Ukuze kuklanywe intwasahlobo efanelekile, inqubo yokwenza ngcono kumele yenziwe. Ngaphakathi kokwenza ngcono intwasahlobo, kunezinhlelo zokusebenza ezahlukahlukene ezincwadini.
UParedes nabanye.8 bachaze isici sokuphila sokukhathala esiphezulu njengomsebenzi oqondile wokuklama iziphethu ze-helical futhi basebenzisa indlela ye-quasi-Newtonian njengendlela yokwenza ngcono. Izinto eziguquguqukayo ekwenzeni ngcono zihlonzwe njengobubanzi bentambo, ububanzi bekhoyili, inani lokujika, kanye nobude bentwasahlobo. Enye ipharamitha yesakhiwo sentwasahlobo yinto eyenziwe ngayo. Ngakho-ke, lokhu kwacatshangelwa ezifundweni zokuklama nokwenza ngcono. UZebdi nabanye. 9 babeka imigomo yokuqina okuphezulu kanye nesisindo esincane emsebenzini oqondile esifundweni sabo, lapho isici sesisindo sasibalulekile. Kulokhu, bachaze izinto zentwasahlobo kanye nezakhiwo zejiyometri njengeziguquguquki. Basebenzisa i-algorithm yezakhi zofuzo njengendlela yokwenza ngcono. Embonini yezimoto, isisindo sezinto siwusizo ngezindlela eziningi, kusukela ekusebenzeni kwemoto kuya ekusetshenzisweni kukaphethiloli. Ukunciphisa isisindo ngenkathi kulungiswa iziphethu zekhoyili zokumiswa kuyisifundo esaziwayo10. UBahshesh noBahshesh11 bathole izinto ezifana ne-E-glass, i-carbon kanye ne-Kevlar njengeziguquguquki emsebenzini wabo endaweni ye-ANSYS ngenhloso yokufinyelela isisindo esincane kanye namandla aphezulu okudonsa emiklamo ehlukahlukene ye-suspension spring composite. Inqubo yokukhiqiza ibalulekile ekuthuthukisweni kweziphethu ezihlanganisiwe. Ngakho-ke, iziguquguquko ezahlukahlukene ziyabandakanyeka enkingeni yokwenza ngcono, njengendlela yokukhiqiza, izinyathelo ezithathwe kule nqubo, kanye nokulandelana kwalezo zinyathelo12,13. Lapho kuklanywa iziphethu zezinhlelo ezishintshashintshayo, amaza emvelo esistimu kumele acatshangelwe. Kunconywa ukuthi imvamisa yokuqala yemvelo yentwasahlobo ibe okungenani izikhathi ezi-5-10 kunemvamisa yemvelo yesistimu ukuze kugwenywe ukugqama14. UTaktak et al. 7 banqume ukunciphisa isisindo sentwasahlobo futhi bandise imvamisa yokuqala yemvelo njengemisebenzi eqondile ekwakhiweni kwentwasahlobo yekhoyili. Basebenzise usesho lwephethini, iphuzu langaphakathi, isethi esebenzayo, kanye nezindlela ze-algorithm zezakhi zofuzo kuthuluzi lokwenza ngcono leMatlab. Ucwaningo lokuhlaziya luyingxenye yocwaningo lokuklama intwasahlobo, kanti i-Finite Element Method idumile kule ndawo15. UPatil et al.16 bathuthukise indlela yokwenza ngcono yokunciphisa isisindo sentwasahlobo ye-helical yokucindezela besebenzisa inqubo yokuhlaziya futhi bahlola ama-analytical equations besebenzisa indlela ye-finite element. Enye indlela yokwandisa ukusebenza kwentwasahlobo ukwanda kwamandla engawagcina. Leli cala liphinde liqinisekise ukuthi intwasahlobo igcina ukusebenza kwayo isikhathi eside. URahul noRameshkumar17 Bafuna ukunciphisa umthamo wentwasahlobo nokwandisa amandla okucindezeleka ekwakhiweni kwentwasahlobo ye-coil yemoto. Basebenzise futhi ama-algorithms ezakhi zofuzo ocwaningweni lokwenza ngcono.
Njengoba kungabonakala, amapharamitha ocwaningweni lokwenza ngcono ayahlukahluka kusuka ohlelweni kuya ohlelweni. Ngokuvamile, amapharamitha okuqina kanye nokucindezeleka kokucheba abalulekile ohlelweni lapho umthwalo othwalayo kuyisici esinqumayo. Ukukhethwa kwezinto kufakiwe ohlelweni lomkhawulo wesisindo ngala mapharamitha amabili. Ngakolunye uhlangothi, amaza emvelo ayahlolwa ukuze kugwenywe ukuzwelana ezinhlelweni ezishintshashintshayo kakhulu. Ezinhlelweni lapho ukusetshenziswa kwezinsiza kusebenza kubaluleke khona, amandla ayakhuliswa. Ezifundweni zokwenza ngcono, yize i-FEM isetshenziselwa izifundo zokuhlaziya, kungabonakala ukuthi ama-algorithm e-metaheuristic njenge-algorithm yezakhi zofuzo14,18 kanye ne-algorithm ye-gray wolf19 asetshenziswa kanye nendlela yakudala yaseNewton ngaphakathi kwemingcele ethile. Ama-algorithm e-metaheuristic athuthukiswe ngokusekelwe ezindleleni zokuzivumelanisa zemvelo ezisondela esimweni esifanele esikhathini esifushane, ikakhulukazi ngaphansi kwethonya labantu20,21. Ngokusatshalaliswa okungahleliwe kwabantu endaweni yokusesha, bagwema i-optima yendawo futhi baqhubekela phambili ku-optima yomhlaba wonke22. Ngakho-ke, eminyakeni yamuva nje ibilokhu isetshenziswa kakhulu kumongo wezinkinga zangempela zezimboni23,24.
Icala elibalulekile lendlela yokugoqa eyakhiwe kulolu cwaningo ukuthi amaphiko, ayesendaweni evaliwe ngaphambi kokundiza, avuleka isikhathi esithile ngemva kokuphuma epayipini. Ngemva kwalokho, into ekhiyayo ivimba iphiko. Ngakho-ke, iziphethu azithinti ngqo amandla okundiza. Kulesi simo, umgomo wokwenza ngcono kwakuwukukhulisa amandla agciniwe ukuze kusheshiswe ukunyakaza kwentwasahlobo. Ububanzi bokugoqa, ububanzi bentambo, inani lama-roll kanye nokuphambuka kwachazwa njengemingcele yokwenza ngcono. Ngenxa yobukhulu obuncane bentwasahlobo, isisindo asizange sibhekwe njengomgomo. Ngakho-ke, uhlobo lwezinto ezibonakalayo luchazwa njengoluzinzile. Umkhawulo wokuphepha kokuguquguquka kwemishini unqunywa njengomkhawulo obalulekile. Ngaphezu kwalokho, imikhawulo yobukhulu obuguquguqukayo ihilelekile kububanzi bendlela. Indlela ye-BA metaheuristic yakhethwa njengendlela yokwenza ngcono. I-BA yathandwa ngenxa yesakhiwo sayo esiguquguqukayo nesilula, kanye nentuthuko yayo ocwaningweni lokwenza ngcono kwemishini25. Engxenyeni yesibili yocwaningo, izinkulumo zezibalo ezinemininingwane zifakiwe ohlakeni lomklamo oyisisekelo kanye nomklamo wentwasahlobo wendlela yokugoqa. Ingxenye yesithathu iqukethe i-algorithm yokwenza ngcono kanye nemiphumela yokwenza ngcono. Isahluko 4 senza ukuhlaziywa ohlelweni lwe-ADAMS. Ukufaneleka kweziphethu kuyahlaziywa ngaphambi kokukhiqizwa. Ingxenye yokugcina iqukethe imiphumela yokuhlola kanye nezithombe zokuhlola. Imiphumela etholakale ocwaningweni nayo iqhathaniswa nomsebenzi wangaphambilini wababhali besebenzisa indlela ye-DOE.
Amaphiko athuthukiswe kulolu cwaningo kufanele agoqeke aye ebusweni berokhethi. Amaphiko ajikeleza kusukela endaweni egoqekile kuya endaweni evulekile. Ngenxa yalokhu, kwakhiwe indlela ekhethekile. Ku-Fig. 1 kukhombisa ukucushwa okugoqekile nokuvulekile5 ohlelweni lwerokhethi lokuhlela.
Ku-fig. 2 kukhombisa umbono wesigaba sale ndlela yokusebenza. Le ndlela yokusebenza inezingxenye eziningana zemishini: (1) umzimba oyinhloko, (2) umphini wephiko, (3) ibhereyi, (4) umzimba wokukhiya, (5) isihlahla sokukhiya, (6) iphini yokumisa, (7) intwasahlobo yokugoba kanye (8) neziphethu zokucindezela. Umphini wephiko (2) uxhunywe entwasahlobo yokugoba (7) ngesikhafu sokukhiya (4). Zonke izingxenye ezintathu zijikeleza ngesikhathi esisodwa ngemva kokuba irokhethi isuke. Ngale ntshukumo yokujikeleza, amaphiko aphendukela endaweni yawo yokugcina. Ngemva kwalokho, iphini (6) iqhutshwa yintwasahlobo yokugoba (8), ngaleyo ndlela ivimbe yonke indlela yomzimba wokukhiya (4)5.
I-modulus enwebekayo (E) kanye ne-modulus ye-shear (G) yizici ezibalulekile zomklamo wentwasahlobo. Kulolu cwaningo, ucingo lwensimbi yentwasahlobo enekhabhoni ephezulu (intambo yomculo i-ASTM A228) lukhethwe njengezinto zasentwasahlobo. Amanye amapharamitha ububanzi bentambo (d), ububanzi bekhoyili obumaphakathi (Dm), inani lamakhoyili (N) kanye nokuphambuka kwentwasahlobo (xd yeziphethu zokucindezela kanye ne-θ yeziphethu zokudonsa)26. Amandla agciniwe eziphethu zokucindezela \({(SE}_{x})\) kanye neziphethu zokudonsa (\({SE}_{\theta}\)) angabalwa kusukela ku-equation. (1) kanye (2)26. (Inani le-modulus ye-shear (G) lentwasahlobo yokucindezela lingu-83.7E9 Pa, kanti inani le-modulus ye-elastic (E) lentwasahlobo yokudonsa lingu-203.4E9 Pa.)
Ubukhulu bomshini besistimu bunquma ngqo imikhawulo yejometri yentwasahlobo. Ngaphezu kwalokho, izimo lapho irokhethi izotholakala khona kufanele nazo zicatshangelwe. Lezi zici zinquma imikhawulo yamapharamitha entwasahlobo. Omunye umkhawulo obalulekile yisici sokuphepha. Incazelo yesici sokuphepha ichazwe ngokuningiliziwe nguShigley et al.26. Isici sokuphepha sentwasahlobo yokucindezela (i-SFC) sichazwa njengokucindezeleka okuphezulu okuvunyelwe okuhlukaniswe ukucindezeleka phezu kobude obuqhubekayo. I-SFC ingabalwa kusetshenziswa ama-equation. (3), (4), (5) kanye no-(6)26. (Ngezinto zentwasahlobo ezisetshenziswe kulolu cwaningo, \({S}_{sy}=980 MPa\)). U-F umele amandla ku-equation kanti i-KB imele isici seBergstrasser esingu-26.
Isici sokuphepha se-torsion sesipringi (SFT) sichazwa ngokuthi i-M ihlukaniswe ngo-k. I-SFT ingabalwa kusukela ku-equation. (7), (8), (9) kanye no-(10)26. (Ngezinto ezisetshenziswe kulolu cwaningo, \({S}_{y}=1600 \mathrm{MPa}\)). Ku-equation, i-M isetshenziselwa i-torque, \({k}^{^{\prime}}\) isetshenziselwa i-spring constant (i-torque/rotation), kanti i-Ki isetshenziselwa i-stress correction factor.
Umgomo oyinhloko wokwenza ngcono kulolu cwaningo ukukhulisa amandla entwasahlobo. Umsebenzi ohlosiwe wenzelwe ukuthola \(\overrightarrow{\{X\}}\) okhulisa \(f(X)\). \({f}_{1}(X)\) kanye \({f}_{2}(X)\) yimisebenzi yamandla yentwasahlobo yokucindezela kanye neyokugoba, ngokulandelana. Iziguquguquko ezibaliwe kanye nemisebenzi esetshenziselwa ukwenza ngcono iboniswe kulezi zibalo ezilandelayo.
Imikhawulo eyahlukene ebekwe ekwakhiweni kwentwasahlobo inikezwe kulezi zibalo ezilandelayo. Izibalo (15) kanye (16) zimele izici zokuphepha zezintwasahlobo zokucindezela kanye nezokugoba, ngokulandelana. Kulesi sifundo, i-SFC kumele ibe nkulu noma ilingane no-1.2 kanti i-SFT kumele ibe nkulu noma ilingane no-θ26.
I-BA iphefumulelwe amasu okufuna impova yezinyosi27. Izinyosi zifuna ngokuthumela izinyoni eziningi ezifuna impova emasimini avundile kanye nezinyoni ezimbalwa ezifuna impova emasimini avundile kakhulu. Ngakho-ke, ukusebenza kahle okukhulu okuvela kubantu bezinyosi kuyatholakala. Ngakolunye uhlangothi, izinyosi ezifuna impova ziyaqhubeka nokufuna izindawo ezintsha zempova, futhi uma kunezindawo ezikhiqiza kakhulu kunangaphambili, izinyoni eziningi ezifuna impova zizoqondiswa kule ndawo entsha28. I-BA inezingxenye ezimbili: usesho lwendawo kanye nosesho lomhlaba wonke. Usesho lwendawo lusesha imiphakathi eminingi eduze nenani eliphansi (izindawo ezivelele), njengezinyosi, kanye nosesho oluncane kwamanye amasayithi (izindawo ezinhle noma ezikhethiwe). Usesho olungenanjongo lwenziwa engxenyeni yokusesha yomhlaba wonke, futhi uma kutholakala amanani amahle, iziteshi zithuthelwa engxenyeni yokusesha yendawo ku-iteration elandelayo. I-algorithm iqukethe amapharamitha athile: inani lezinyosi ezifuna impova (n), inani lezindawo zokusesha zendawo (m), inani lezindawo ezivelele (e), inani lezinyoni ezifuna impova ezindaweni ezivelele (nep), inani lezinyoni ezifuna impova ezindaweni ezifanele. Indawo (nsp), usayizi wendawo (ngh), kanye nenani lokuphindaphinda (I)29. I-pseudocode ye-BA iboniswe kuMfanekiso 3.
I-algorithm izama ukusebenza phakathi kwe-\({g}_{1}(X)\) kanye ne-\({g}_{2}(X)\). Ngenxa yokuphindaphinda ngakunye, amanani afanele ayanqunywa futhi inani labantu liqoqwa eduze kwala manani ngomzamo wokuthola amanani afanele kakhulu. Imikhawulo iyahlolwa ezingxenyeni zokusesha zendawo nezomhlaba wonke. Ekusesheni kwendawo, uma lezi zici zifanele, inani lamandla liyabalwa. Uma inani elisha lamandla likhulu kunenani elifanele, nikeza inani elisha enanini elifanele kakhulu. Uma inani elihle kakhulu elitholakala kumphumela wokusesha likhulu kunento yamanje, into entsha izofakwa eqoqweni. Umdwebo webhlokhi wokusesha kwendawo uboniswe kuMfanekiso 4.
Inani labantu lingenye yemingcele ebalulekile ku-BA. Kungabonakala ezifundweni zangaphambilini ukuthi ukwandisa inani labantu kunciphisa inani lokuphindaphinda okudingekayo futhi kwandisa amathuba okuphumelela. Kodwa-ke, inani lokuhlolwa kokusebenza nalo liyakhula. Ukuba khona kwenani elikhulu lezindawo eziphakeme akuthinti kakhulu ukusebenza. Inani lezindawo eziphezulu lingaba liphansi uma lingekho ku-zero30. Usayizi wenani lezinyosi ze-scout (n) uvame ukukhethwa phakathi kuka-30 no-100. Kulesi sifundo, zombili izimo ezingu-30 no-50 zaqhutshwa ukuze kutholakale inani elifanele (Ithebula 2). Amanye amapharamitha anqunywa kuye ngenani labantu. Inani lezindawo ezikhethiwe (m) (cishe) lingu-25% wosayizi wenani labantu, kanti inani lezindawo eziphezulu (e) phakathi kwezindawo ezikhethiwe lingu-25% we-m. Inani lezinyosi ezondlayo (inani lokusesha) lakhethwa ukuba libe yi-100 yezindawo eziphezulu kanye ne-30 yezinye izindawo zendawo. Ukusesha omakhelwane kungumqondo oyisisekelo wazo zonke izindlela zokuziphendukela kwemvelo. Kulesi sifundo, kwasetshenziswa indlela yokunciphisa omakhelwane. Le ndlela inciphisa usayizi wendawo ngesilinganiso esithile ngesikhathi sokuphindaphinda ngakunye. Ekuphindaphindeni kwesikhathi esizayo, amanani amancane endawo30 angasetshenziswa ekusesheni okunembe kakhudlwana.
Esimweni ngasinye, kwenziwa izivivinyo eziyishumi ezilandelanayo ukuze kuhlolwe ukuphindaphindwa kwe-algorithm yokwenza ngcono. Ku-fig. 5 kukhombisa imiphumela yokwenza ngcono intwasahlobo yokugoba yeskimu 1, naku-fig. 6 - yeskimu 2. Idatha yokuhlola inikezwe futhi kumathebula 3 no-4 (ithebula eliqukethe imiphumela etholwe yentwasahlobo yokucindezela liselwazini olungeziwe S1). Inani lezinyosi likhulisa ukusesha kwamanani amahle ku-iteration yokuqala. Esimweni 1, imiphumela yokuhlolwa okuthile yayingaphansi komkhawulo ophezulu. Esimweni 2, kungabonakala ukuthi yonke imiphumela yokwenza ngcono isondela komkhawulo ophezulu ngenxa yokwanda kwabantu kanye neminye imingcele efanele. Kungabonakala ukuthi amanani ku-Scenario 2 anele i-algorithm.
Uma kutholwa inani eliphezulu lamandla ekuphindaphindeni, isici sokuphepha sinikezwa njengesivimbelo socwaningo. Bheka ithebula lesici sokuphepha. Amanani wamandla atholakale kusetshenziswa i-BA aqhathaniswa nalawo atholakale kusetshenziswa indlela ye-5 DOE kuThebula 5. (Ukuze kube lula ukukhiqiza, inani lokujika (N) kwentwasahlobo ye-torsion lingu-4.9 esikhundleni sika-4.88, kanti ukuphambuka (xd) kungu-8 mm esikhundleni sika-7.99 mm entwasahlobo yokucindezela.) Kungabonakala ukuthi i-BA ingcono Umphumela. I-BA ihlola wonke amanani ngokubheka kwendawo kanye nomhlaba wonke. Ngale ndlela ingazama ezinye izindlela ngokushesha.
Kulesi sifundo, u-Adams wasetshenziswa ukuhlaziya ukunyakaza kwendlela yokusebenza kwephiko. U-Adams uqale anikezwe imodeli ye-3D yale ndlela yokusebenza.

Ngemuva kwalokho amaphiko akhululwa endaweni egoqiwe futhi kwenziwa ividiyo yokujikeleza kwamaphiko kusukela endaweni egoqiwe kuya kweyodwa esetshenzisiwe. I-timer yasetshenziswa futhi ukuhlaziya isikhathi ngesikhathi sokuqoshwa kwevidiyo.
Ku-fig. 8 kukhombisa ozimele bevidiyo abanombolo 1-4. Inombolo yohlaka 1 esithombeni ikhombisa isikhathi sokukhululwa kwamaphiko agoqiwe. Lo mzuzu ubhekwa njengomzuzu wokuqala wesikhathi t0. Ozimele 2 no-3 bakhombisa izikhundla zamaphiko 40 ms kanye no-70 ms ngemuva komzuzu wokuqala. Uma kuhlaziywa ozimele 3 no-4, kungabonakala ukuthi ukunyakaza kwephiko kuzinza 90 ms ngemuva t0, futhi ukuvulwa kwephiko kuqedwa phakathi kuka-70 no-90 ms. Lesi simo sisho ukuthi kokubili ukuhlolwa kokulingisa kanye nokuhlolwa kweprototype kunikeza cishe isikhathi esifanayo sokufakwa kwephiko, futhi umklamo uhlangabezana nezidingo zokusebenza zendlela yokusebenza.
Kulesi sihloko, iziphethu ze-torsion kanye ne-compression ezisetshenziswa ku-wing folding mechanism zithuthukiswa kusetshenziswa i-BA. Amapharamitha angafinyelelwa ngokushesha ngeziphindaphindo ezimbalwa. I-torsion spring ilinganiswe ku-1075 mJ kanti i-compression spring ilinganiswe ku-37.24 mJ. Lawa manani angcono ngo-40-50% kunezifundo zangaphambilini ze-DOE. I-spring ihlanganiswe ku-mechanism futhi ihlaziywe ohlelweni lwe-ADAMS. Lapho ihlaziywe, kwatholakala ukuthi amaphiko avuleka ngaphakathi kwama-millisecond angu-74. Leli nani lingaphansi kakhulu kwenhloso yephrojekthi yama-millisecond angu-200. Esifundweni sokuhlola esilandelayo, isikhathi sokuvula sasilinganiswa cishe ngama-90 ms. Lo mehluko wama-millisecond angu-16 phakathi kokuhlaziywa ungase ube ngenxa yezici zemvelo ezingafakwanga kusofthiwe. Kukholakala ukuthi i-algorithm yokwenza ngcono etholwe ngenxa yocwaningo ingasetshenziswa ekwakhiweni kwentwasahlobo ehlukahlukene.
Izinto zasentwasahlobo zazichazwe kusengaphambili futhi azizange zisetshenziswe njengento eguquguqukayo ekwenzeni ngcono. Njengoba izinhlobo eziningi ezahlukene zezintwasahlobo zisetshenziswa ezindizeni nasemarokhethini, i-BA izosetshenziswa ukuklama ezinye izinhlobo zezintwasahlobo kusetshenziswa izinto ezahlukene ukuze kufezwe umklamo wentwasahlobo omuhle kakhulu ocwaningweni lwesikhathi esizayo.
Simemezela ukuthi lo mbhalo ungowoqobo, awukaze ushicilelwe ngaphambilini, futhi okwamanje awucatshangelwa ukushicilelwa kwenye indawo.
Yonke idatha ekhiqizwe noma ehlaziyiwe kulolu cwaningo ifakiwe kulesi sihloko esishicilelwe [kanye nefayela lolwazi olwengeziwe].
