Munthawi yanga ku DSpower, ndidazindikira kuti anthu ambiri samamvetsetsa kufunika kwa ma servos mundege zokhazikika. Pambuyo pake, paulendo woyesa ndege, ndidawona ndege yamapiko osasunthika ikutaya kukhazikika kwake chifukwa cha kuyankha kwaulesi kwa servo.

Apa m'pamene ndinazindikira kufunikira kofunikira kwa gawo lomwe likuwoneka ngati laling'ono. Tikayang'ana m'mbuyo, zomwe zinachitikazo zidalimbikitsa gulu lathu la R&D kupita patsogolo.

Chifukwa chiyani ndege zamapiko okhazikika sizingachite popanda ma servos apamwamba kwambiri

Mosiyana ndi makina opangira ma motors ambiri, omwe amagwiritsa ntchito injini zambiri kuti asinthe malingaliro awo, ndege zamapiko osasunthika zimadalira kwambiri malo omwe amawongolera ndege kuti aziwongolera komwe akuuluka. Kuyenda kulikonse kwa ma ailerons, ma elevator, ndi chiwongolero kumafuna kuphedwa molondola ndi ma servos.

Kuyesa kwa chaka chatha kunawonetsa kuti ma servos achikhalidwe amakumana ndi kuchedwa kwachiwiri kwa 0.5 pakuyenda kwamphamvu kwa mpweya, kokwanira kupangitsa ndege kuyenderera madigiri 20. Kuti tithetse vutoli, timapereka njira zitatu:
1. Chepetsani kuchedwa pogwiritsa ntchito mapulogalamu apadera
2. Sinthani liwiro la mayankho a servo
3. Chepetsani kuchuluka kwa zida

Kusinthasintha kwa kutentha kumabweretsanso ngozi. Munthu wogwiritsa ntchito zida za pulasitiki akusweka paulendo wa pandege kumpoto kwa dzinja pa -15°C, zomwe zinachititsa kuti awonongeke nthawi yomweyo akatera. Ma servos athu onse a mapiko okhazikika tsopano amagwiritsa ntchito aluminiyamu ya giredi ya ndege pama gearbox awo ndikuphatikiza zowunikira zamkati zamkati. Kusintha komwe kumawoneka ngati kochepaku kumatha kupulumutsa moyo munthawi zovuta.

Momwe mungadziwire ngati servo ndi yoyenera pa zosowa za ndege zamapiko

Kuwongolera liwiro ndi mphamvu kumafuna kulinganiza koyenera. Nayi kuwerengera: chulukitsani kutalika kwa mapiko ndi liwiro la kuwuluka, kenaka gawani ndi 100 kuti mudziwe mphamvu yofunikira. Mwachitsanzo, ngati phiko ndi lalitali mamita awiri ndipo kuthamanga kwa ndege kufika mamita 15 pamphindi, servo ndi mphamvu ya osachepera 0.3 kg · cm2 chofunika.

Komabe, pakugwira ntchito kwenikweni, kusungitsa 30% kumafunika kuthana ndi kusintha kwadzidzidzi kwa liwiro la mphepo.

Kutsekereza madzi nthawi zambiri kumanyalanyazidwa. Zaka ziwiri zapitazo, tinathandiza kasitomala wina kusintha ndege yoyang'ana mapiko okhazikika. Ndikuwuluka pamtambo wamtambo, chinyezi chimalowa mu servo, ndikupangitsa kuti ziziwongolera zosakhazikika.

Yankho lathu lapano ndikuyika zisindikizo za silicone ziwiri pa shaft yotulutsa, kuphatikiza bolodi yozungulira ya nano. Kuyesa kumunda kwawonetsa kuti ndegeyo imatha kugwira ntchito bwino ngakhale pamvula yamkuntho.

Momwe DSpower imathetsera zosowa zapadera za mapiko okhazikika

Tapanga mwapadera njira yopewera kugwedezeka. Pamene kugwedezeka kwafupipafupi kwa injini yokhazikika ya mapiko ndipamwamba,Izi zingayambitse kugwedezeka kwa ma servos wamba. Pakuyesa kumodzi, servo idagwedezeka mwamphamvu komanso mosalamulirika.

Zogulitsa zonse tsopano zimayesedwa kwa maola 48 pazida zogwedezeka musanachoke kufakitale, zokhala ndi ma frequency kuyambira 50 Hz mpaka 2000 Hz kutengera momwe ndege zimakhalira.

Kuti tikwaniritse zofuna za ulendo wautali wouluka, timagwiritsa ntchito luso lapadera lotchedwa dynamic energy consumption adjustment. Zipangizo zoyang'anira wamba zimawononga mphamvu ngakhale zitakhala zopanda ntchito. Timagwiritsa ntchito masensa a Hall effect kuti tidziwe komwe kuli malo owongolera ndikusinthiratu kugwiritsa ntchito mphamvu ya microampere tikangozindikira kuti yaima.

Chida chowongolera chomwe tidapangira ndege zathu zoyendera dzuwa chaka chatha chidathandizira kupirira kwa ndege yonse, ndikuwonjezera nthawi yowuluka ndi 17%.

Kusamala Kuyika kwa Servo pa Ndege Yokhazikika Yamapiko

Pakatikati pa mphamvu yokoka ndi yofunika kwambiri. Anthu ena amayika gawo lowongolera kunja kwa mapiko, zomwe zingayambitse kulumikizana panthawi yopukutira. Zimavomerezedwa kuti gawo lowongolera liyenera kukhazikitsidwa pa 30% ya kutalika kwa fuselage centerline. Udindowu umachepetsa kusokoneza kwa aerodynamic ndikuchepetsa kusinthasintha kozungulira. Kuyika kolowera ndikofunikira: tsinde lotulutsa liyenera kukhala lolunjika ku hinge centerline; apo ayi, kupatuka kowongolera kungachitike.

Mayendedwe a chingwe amafunika kusamalitsa. Nthawi ina, kasitomala anamanga chingwe cha servo mwamphamvu kwambiri, ndipo phikolo lidapindika ndikulikoka panthawi yowuluka, zomwe zidapangitsa kuti malo olumikiziranawo amasuke. Tsopano zingwe zazitsulo zomwe timapereka ndi zipangizo zimakhala ndi 5mm gap. Ndipo waya wapadera wa silicone amagwiritsidwa ntchito kuti asawonongeke pa kutentha kochepa.

Malo osungira tsiku ndi tsiku a ma servos okhazikika

Kunyamula mafuta kumafuna chisamaliro chapadera. Mafuta wamba sayenera kugwiritsidwa ntchito. Makasitomala omwe adachita izi adapangitsa kuti servo ikhale yolimba ndikugwira kutentha pang'ono. Mafuta omwe timapereka amapangidwa mwapadera kuti asunge kukhuthala koyenera pakati pa -40°C ndi 120°C.

Nthawi yokonzekera yokonzedwa ndikukonzanso maola 50 aliwonse othawa. Ngati agwiritsidwa ntchito m'madera achipululu, nthawiyi iyenera kufupikitsidwa mpaka maola 30.

Kuwona pafupipafupi kulimba kwa magiya ndikofunikira. Ndege yophunzitsira yomwe inali ndi maola opitilira 200 othawa idawonongeka ndikung'ambika, zomwe zidapangitsa kusewera, zomwe zidapangitsa kuti chiwongolerocho chigwire mwadzidzidzi potera.

Pakalipano timapereka makasitomala ma geji omveka kuti awalangize kuti ayang'ane kusewera kwa zida ndikukonza mipata iliyonse yopitilira 0.1 mm. Mchitidwewu waletsa ngozi zambiri.

Ndi chitukuko chanji chaukadaulo chomwe ma servos okhazikika amtsogolo adzagwira?

Maginito encoder omwe amagwiritsidwa ntchito poyesa ndi odabwitsa. Ma potentiometer achikhalidwe amatha m'kupita kwanthawi, koma njira yathu yatsopano yolumikizira yosalumikizana imagonjetseratu vutoli. Sabata yatha, chitsanzo choyesedwa pansi pa mikhalidwe yopopera mchere chinagwira ntchito mosalekeza kwa maola 500 popanda kusinthasintha kulikonse, kukulitsa moyo wake wautumiki kakhumi. Ndikuyembekezera mwachidwi dongosolo lanzeru la servo.

Servo iliyonse imakhala ndi microprocessor yomwe imatha kuzindikira zolakwika. Mwachitsanzo, ngati giya yatsekeredwa, imangosintha kukhala njira yosunga zobwezeretsera kuti muchepetse ngodya ya yaw. Ukadaulo uwu ukakwaniritsidwa, uthandizira kwambiri chitetezo cha mapiko osasunthika.
