Munguva yangu paDSpower, ndakaona kuti vanhu vazhinji vaisanyatsonzwisisa kukosha kwemaservos mundege ine mapapiro. Gare gare, panguva yekuedza ndege, ndakaona ndege yemapapiro isina kugadzikana ichirasikirwa nekugadzikana kwayo nekuda kwekunonoka kwe servo mhinduro.
Ipapo ndipo pandakaona kukosha kwakakosha kwechinhu chaiita sechidiki ichi. Ndichitarisa kumashure, chiitiko ichocho chakanyatsokurudzira timu yedu yeR&D kufambira mberi kwakakosha.
Sei ndege dzakasimba dzemapapiro dzisingakwanise kuita pasina servos yakakwirira
Kusiyana nema multirotor, anoshandisa mota dzakawanda kugadzirisa maitiro avo, ndege dzemapapiro dzinotsamira zvachose pane aerodynamic control surface kudzora mafambiro ekubhururuka. Kufamba kwese kweailerons, elevator, uye rudder kunoda kuurayiwa chaiko nema servos.
Kuyedzwa kwegore rapfuura kwakaratidza kuti echinyakare servos inosangana ne 0.5 sekondi kunonoka mukumhanya kwemhepo kuyerera, zvakaringana kuita kuti ndege iite madhigirii makumi maviri. Kugadzirisa dambudziko iri, tinopa nzira nhatu:
1. Deredza kunonoka kuburikidza nehunyanzvi software control
2. Kuvandudza servo mhinduro yekumhanya
3. Deredza chiyero chegiya
Kuchinja-chinja kwekushisa kunokonzerawo njodzi. Mushandisi akasangana nekutsemuka kwegiya repurasitiki panguva yekubhururuka muchando chekuchamhembe pa -15°C, zvichikonzera kukuvara nekukasika pakumhara. Yese yedu yakagadziriswa bapiro servos ikozvino inoshandisa ndege giredhi aluminium kune magiya mabhokisi uye inobatanidza emukati tembiricha sensors. Idzi budiriro dzinoita sediki dzinogona kuponesa hupenyu munguva dzakaoma.
Nzira yekuziva sei kana servo inokodzera zvakagadziriswa mapapiro endege zvinodiwa
Kudzora kumhanya uye simba kunoda mwero wakaenzana. Heino chiverengero: wedzera urefu hwebapiro nekumhanya kwendege, wogovanisa nezana kuti uone simba rinodiwa. Semuenzaniso, kana bapiro rakareba mamita maviri uye kumhanya kwendege kunosvika mamita gumi nemashanu pasekondi, servo ine simba rinosvika 0.3 kg·cm2 inodiwa.
Nekudaro, mukushanda chaiko, 30% inochengeterwa inodiwa kuti utsungirire nekungoerekana wachinja mukumhanya kwemhepo.
Kudzivirira mvura kunowanzo kanganwa. Makore maviri apfuura, takabatsira mutengi kushandura ndege inoongorora yemapapiro. Ndichiri kubhururuka nekavha yegore, mwando wakapinda mu servo, zvichikonzera kusagadzikana masaini ekudzora.
Mhinduro yedu yazvino ndeyekuisa mbiri silicone zvisimbiso pane inobuda shaft, yakasanganiswa ne nano coated redunhu bhodhi. Kuongororwa kwemumunda kwakaratidza kuti ndege inogona kushanda zvakajairwa kunyangwe mukunaya kukuru.
Iyo DSpower inogadzirisa sei zvakakosha zvinodiwa zveyakagadziriswa bapiro servos
Isu takanyatso gadzira nzira yekudzivisa vibration. Kana iyo vibration frequency yejini yakagadziriswa yakakwira,Izvi zvinogona kukonzera kukwenya kwechiratidzo mumasevhisi akajairwa. Panguva imwe bvunzo, servo oscilled nechisimba uye asingadzoreki.
Zvigadzirwa zvese zvino zvinopiswa kwemaawa makumi mana nemasere mukuyedzwa pamudziyo wevibration usati wabuda mufekitori, uine ma frequency anotangira pa50 Hz kusvika 2000 Hz kutevedzera akasiyana mamiriro ekubhururuka.
Kuti tisangane nezvinodiwa zvekubhururuka kwenguva refu, tinoshandisa tekinoroji yakakosha inodaidzwa kuti dynamic energy kushandiswa kugadzirisa. Zvishandiso zvechinyakare zvekudzora zvinopedza simba kunyangwe zvisina basa. Isu tinoshandisa Hall effect sensors kuona nzvimbo yekutonga uye otomatiki chinja kune microampere level mashandisiro emagetsi kana vangoona yakamira.
Mudziyo wekudzora watakashongedza ndege yedu ine simba rezuva gore rapfuura yakawedzera zvakanyanya kutsungirira kwendege yese, ichiwedzera nguva yekubhururuka ne17%.
Servo Kuisa Chengetedzo paFixed Wing Ndege
Pakati pesimba rinokwevera zvinhu pasi pakakosha. Vamwe vanhu vanoisa iyo control unit kunze kwebapiro, izvo zvinogona kukonzera chinongedzo mhedzisiro panguva yekudonha. Zvinowanzogamuchirwa kuti chikwata chekutonga chinofanira kuiswa pa 30% yehurefu hwehurefu hwe fuselage centerline. Iyi nzvimbo inoderedza kupindira kweaerodynamic uye inoderedza kutenderera inertia. Kuiswa kwekutarisa kwakakoshawo: iyo shaft yekubuda inofanira kunge iri perpendicular kune hinge centerline; zvimwe, kudzora kutsauka kunogona kuitika.
Cable routing inoda kunyatsotariswa. Pane imwe nguva, mutengi akasunga servo tambo zvakasimba, uye bapiro rakanga rakakotama uye richidhonzwa panguva yekubhururuka, zvichiita kuti nzvimbo yekubatanidza isununguke. Iye zvino tambo dzetambo dzatinopa nemichina dzine gap 5mm. Uye yakakosha silicone wire inoshandiswa kudzivisa kuva brittle pakupisa kwakadzika.
Mazuva ese ekugadzirisa mapoinzi eiyo fixed wing servos
Kutakura lubrication kunoda kunyatsotarisirwa. Mafuta emazuva ose haafaniri kushandiswa. Mutengi akaita izvi akaita kuti servo iome uye ibate mukudziya kwakaderera. Girisi yatinopa yakanyatsogadzirwa kuchengetedza viscosity yakakodzera pakati -40°C kusvika 120°C.
Iyo inokurudzirwa kugadzirisa nguva ndeye relubrication maawa makumi mashanu ega ega ekubhururuka. Kana ikashandiswa munzvimbo dzerenje, nguva iyi inofanira kupfupikiswa kusvika maawa makumi matatu.
Kugara uchitarisa kusimba kwemagiya kwakakosha. Ndege yekudzidzira ine maawa anopfuura 200 ekubhururuka yakaona kupera uye kubvaruka mumagiya, zvichikonzera kutamba, izvo zvakaita kuti chidzoreso chibve chabata panguva yekumhara.
Isu parizvino tinopa vatengi ma feeler geji ekuvaraira kuti vatarise kutamba kwegiya uye kugadzirisa chero mapundu anopfuura 0.1 mm. Tsika iyi yadzivirira tsaona dzakawanda.
Ndeapi mabudiro etekinoroji achabata ramangwana rakagadziriswa bapiro servos?
Iyo magineti encoder inoshandiswa muyedzo inoshamisa. Chinyakare potentiometers inopera nekufamba kwenguva, asi nzira yedu ichangobva kugadzirwa yekusaonana inonyatsokunda iyi drawback. Svondo rapfuura, sampuli yakaedzwa pasi pemamiriro emunyu wekupfapfaidza yakashanda nguva dzose kwemaawa mazana mashanu pasina chero shanduko yechiratidzo, ichiwedzera hupenyu hwayo hwesevhisi kagumi. Ndiri kunyanya kumirira nehungwaru servo system.
Imwe neimwe servo ine microprocessor iyo inogona kuona otomatiki mamiriro ekukanganisa. Semuyenzaniso, kana giya rakanamira, rinobva rachinja kuita backup mode kuderedza yaw angle. Kana tekinoroji iyi yakwana, ichavandudza zvakanyanya kuchengetedzeka kwekubhururuka kwemapapiro.
