Ngexesha lokuhlala kwam kwi-DSpower, ndiye ndaqaphela ukuba abantu abaninzi abazange bakuqonde ngokupheleleyo ukubaluleka kwee-servos kwinqwelomoya yamaphiko. Emva kwexesha, ngexesha lovavanyo lokubhabha, ndabona inqwelomoya yamaphiko engatshintshiyo iphulukana nozinzo ngenxa yempendulo ecothayo ye-servo.
Kulapho ndabona khona ukubaluleka kweli candelo libonakala lilincinci. Xa sijonga emva, eso sehlo sikhuthaze iqela lethu leR&D ukuba lenze inkqubela phambili ebalulekileyo.
Kutheni iinqwelomoya zamaphiko ezisisigxina azikwazi ukwenza ngaphandle kwee-servos eziphezulu zokusebenza
Ngokungafaniyo nee-multirotors, ezisebenzisa iinjini ezininzi ukulungelelanisa isimo sazo sengqondo, iinqwelo-moya ezinamaphiko asisigxina zithembele ngokupheleleyo kulawulo lwe-aerodynamic ukulawula indlela ekubhabha kuyo. Yonke intshukumo yeeailerons, iilifti, kunye nerudder ifuna ukubulawa okuchanekileyo ngama-servos.
Uvavanyo lwalo nyaka uphelileyo lubonise ukuba i-servos yemveli ifumana ukulibaziseka kwesibini se-0.5 kwisantya esiphezulu sokuhamba komoya, okwaneleyo ukubangela ukuba inqwelomoya ikhuphe i-20 degrees. Ukuhlangabezana nale ngxaki, sinikezela ngeendlela ezintathu:
1. Ukunciphisa ukulibaziseka ngolawulo lwesoftware ekhethekileyo
2. Ukuphucula isantya sokuphendula se-servo
3. Nciphisa umlinganiselo wegiya
Ukunyuka kwamaqondo obushushu nako kubangela imingcipheko. Umsebenzisi ufumene ukuqhekeka kwezixhobo zeplastiki ngexesha lokubhabha kumantla ebusika kwi--15°C, okubangele umonakalo okhawulezileyo ekufikeni kwakhe. Zonke ii-servos zethu zamaphiko ezisisigxina ngoku zisebenzisa i-aluminiyam yenqanaba lenqwelomoya kwiibhokisi zabo zegiya kwaye zibandakanya izinzwa zobushushu zangaphakathi. Olu phuculo lubonakala luncinci lunokusindisa ubomi ngamaxesha anzima.
Indlela yokufumanisa ukuba i-servo ifanelekile kwiimfuno zenqwelomoya zamaphiko
Ukulawula isantya kunye namandla kufuna ibhalansi elinganayo. Nalu ubalo: phinda-phinda ubude bephiko ngesantya sokubhabha, uze uhlukanise nge-100 ukumisela amandla afunekayo. Ngokomzekelo, ukuba iphiko liziimitha ezimbini ubude kwaye isantya sendiza sifikelela kwiimitha ezili-15 ngomzuzwana, i-servo ene-force ubuncinane ye-0.3 kg · cm2 iyadingeka.
Nangona kunjalo, ekusebenzeni kokwenyani, uvimba we-30% uyafuneka ukumelana notshintsho olukhawulezileyo kwisantya somoya.
Ukuvalwa kwamanzi kudla ngokungahoywa. Kwiminyaka emibini edlulileyo, sanceda umxhasi ukuba aguqule inqwelomoya yamaphiko enokujongisisa. Ngelixa ubhabha kwikhava yelifu, ukufuma kungene kwi-servo, kubangele imiqondiso yolawulo engazinzanga.
Isisombululo sethu sangoku kukufaka izitywina eziphindwe kabini ze-silicone kwi-shaft yokuphuma, kunye nebhodi yesiphaluka efakwe kwi-nano. Uvavanyo lwasebaleni lubonise ukuba inqwelo-moya inokusebenza ngokuqhelekileyo nakwimvula enkulu.
Indlela i-DSpower isombulula ngayo iimfuno ezikhethekileyo zee-servos zamaphiko asisigxina
Siye saphuhlisa ngokukodwa indlela yokumelana nokungcangcazela. Xa i-vibration frequency ye-injini yephiko esisigxina iphezulu，Oku kunokubangela ukukrala komqondiso kwii-servos eziqhelekileyo. Ngexesha lovavanyo olunye, i-servo yajikeleza ngamandla kwaye ingalawuleki.
Zonke iimveliso ngoku zitshiswa iiyure ezingama-48 kuvavanyo kwisixhobo sokungcangcazela phambi kokuba ziphume kumzi-mveliso, ezinezandi ezisuka kwi-50 Hz ukuya kwi-2000 Hz ukulinganisa iimeko ezahlukeneyo zokubhabha.
Ukuhlangabezana neemfuno zenqwelomoya yexesha elide, sisebenzisa ubuchwepheshe obukhethekileyo obubizwa ngokuba luhlengahlengiso lokusetyenziswa kwamandla aguqukayo. Izixhobo zokulawula eziqhelekileyo zisebenzisa amandla naxa zingasebenzi. Sisebenzisa abenzi boluvo besiphumo seHolo ukubona indawo yolawulo kunye nokutshintshela ngokuzenzekelayo kusetyenziso lwamandla lwenqanaba le-microampere xa bebona imeko emileyo.
Isixhobo solawulo esisixhobise ngenqwelomoya yethu esebenza ngelanga kulo nyaka uphelileyo siphucule kakhulu unyamezelo lokubhabha kuyo yonke inqwelomoya, sanyusa ixesha lokubhabha nge-17%.
Imiqathango yokuFakelo lwe-Servo kwiiNqwelo-moya zePhiko eziFixiweyo
Umbindi womxhuzulane ubalulekile. Abanye abantu bafakela iyunithi yokulawula ngaphandle kwephiko, enokubangela umphumo wokudibanisa ngexesha lokuhamba. Ngokuqhelekileyo kuyamkelwa ukuba iyunithi yokulawula kufuneka ifakwe kwi-30% yobude be-chord ye-fuselage centerline. Esi sikhundla sinciphisa ukuphazamiseka kwe-aerodynamic kunye nokunciphisa inertia ejikelezayo. Ukuqhelaniswa nokufakela kubalulekile: i-shaft ephumayo kufuneka ibe yi-perpendicular kwi-hinge centerline; kungenjalo, ukutenxa ulawulo kunokwenzeka.
Indlela yentambo ifuna ukuhoywa ngononophelo. Ngesinye isikhathi, umthengi ubophe intambo ye-servo kakhulu, kwaye iphiko laligobile kwaye litsalwe ngexesha lokubhabha, libangela ukuba indawo yokudibanisa ikhululwe. Ngoku iintambo zekhebula esizibonelela ngezixhobo zine-gap ye-5mm. Kwaye ucingo olukhethekileyo lwe-silicone lusetyenziselwa ukuphepha ukuba lukhuni kumaqondo aphantsi.
Amanqaku olondolozo lwemihla ngemihla yee-servos zamaphiko asisigxina
Ukuthwala i-lubrication kufuna ingqalelo ekhethekileyo. Igrisi eqhelekileyo mayingaze isetyenziswe. Umthengi owenze oku wabangela ukuba i-servo iqine kwaye ibambe kumaqondo aphantsi. Igrisi esiyinikezelayo yenziwe ngokukodwa ukugcina i-viscosity efanelekileyo phakathi kwe -40°C kunye ne-120°C.
Elona thuba licetyiswayo lokulolonga kukuhlaziywa rhoqo kwiiyure ezingama-50 ngenqwelomoya. Ukuba isetyenziswe kwiindawo ezisentlango, eli khefu kufuneka licuthwe libe ziiyure ezingama-30.
Ukujonga rhoqo ukuqina kweegiya kubalulekile. Inqwelomoya yoqeqesho eneeyure zokubhabha ezingaphezulu kwama-200 ziye zaphelelwa ngamandla, nto leyo eyakhokelela ekudlaleni, okubangele ukuba umphini wokujika ubambe ngequbuliso ngexesha lokumisa.
Sithetha nje sibonelela abathengi ngeegeyiji zokubayalela ukuba bajonge ukudlala izixhobo kunye nokulungisa naziphi na izikhewu ezingaphezulu kwe-0.1 mm. Lo mkhwa uthintele iingozi ezininzi.
Zeziphi iimpumelelo zetekhnoloji eziya kubanjwa kwixesha elizayo ngamaphiko asisigxina?
I-encoder magnetic esetyenziswe kuvavanyo iyamangalisa. Ii-potentiometers zesiNtu ziyaphela ngokuhamba kwexesha, kodwa indlela yethu esanda kuyilwa engeyiyo yokunxibelelana iyoyisa ngokupheleleyo le ngxaki. Kwiveki ephelileyo, isampuli evavanyiweyo phantsi kweemeko zokutshiza ityuwa isebenze ngokuqhubekayo iiyure ezingama-500 ngaphandle kokuguquguquka komqondiso, yandisa ubomi bayo benkonzo ngokuphindwe kalishumi. Ndilindele ngomdla inkqubo ye-servo ekrelekrele.
I-servo nganye ixhotyiswe nge-microprocessor enokuchonga ngokuzenzekelayo iimeko eziphosakeleyo. Umzekelo, ukuba igiya ibambekile, iya kutshintshela ngokuzenzekelayo kwimowudi yogcino ukunciphisa i-engile ye-yaw. Nje ukuba le teknoloji ifezekisiwe, iya kuphucula kakhulu ukhuseleko lwe-fixed wing flight.
