Iyo yakakosha pfungwa yefiber optic gyroscope

1, Iyo yakakosha pfungwa yefiber optic gyroscope

Modern fiber optic gyroscope chiridzwa chinokwanisa kunyatsoona mafambiro ezvinhu zvinofamba, iinertial navigation chiridzwa chinoshandiswa zvakanyanya mukubhururuka kwemazuva ano, kufamba, aerospace uye indasitiri yekudzivirira, kusimukira kwayo kwakakosha zvakanyanya kukosha kune indasitiri yenyika, kudzivirira nyika. uye kumwe kukwidziridzwa kwepamusoro-soro.

2, Tsanangudzo yefiber optic gyro

Fiber optic gyroscope chinhu chinonzwisa tsitsi chakavakirwa pane optical fiber coils.Chiedza chinobudiswa kubva kune laser diode chinopararira munzira mbiri pamwe neoptical fiber.Musiyano wenzira yekuparadzira mwenje unosarudza kusimuka kweangular yechinhu chinonzwa.

Zvakanakira zvefiber optic gyroscope zvichienzaniswa neyechinyakare mechanical gyroscope yese yakasimba, hapana zvikamu zvinotenderera uye zvikamu zvinokweshana, hupenyu hwakareba, hukuru hukuru hwesimba, kutanga nekukasira, chimiro chakareruka, diki diki uye huremu huremu.Kana ichienzaniswa nelaser gyroscope, fiber optic gyroscope haina dambudziko rekuvhara uye haidi kunyatsogadzira muchina nzira yekuona mu quartz block, saka mutengo wakaderera.

3, Fiber optic gyro basic working musimboti

Kuitwa kwefiber optic gyroscope kunonyanya kuenderana nedzidziso yeSegnick: kana mwenje wechiedza uchifamba mugero rakaita serin'i, kana chiteshi chemhete pachayo chine kumhanya kwekutenderera, saka nguva inodiwa kuti chiedza chifambe munzira kutenderera kwechanera kunopfuura nguva inodiwa kuti ufambe wakanangana neino kutenderera kwechiteshi.Izvi zvinoreva kuti kana iyo optical loop ichitenderera, chiedza chechiedza che optical loop chinoshanduka munzira dzakasiyana dzekufamba maererano nechiedza chechiedza chekuzorora pakuzorora.Uchishandisa shanduko iyi mumhando ye optical range, mutsauko wechikamu pakati pemaviri optical loops kana kushanduka kwemupendero wekupindira unoonekwa, uye angular velocity ye optical loop rotation inogona kuyerwa, iyo ndiyo inoshanda yefiber optic gyroscope.

4, Segnick's theory sumo

Dzidziso yeSeignik inoti kana mwenje wemwenje ukafamba muchiuno, kana loop pachayo iine spidhi yekutenderera, zvinotora nguva yakawanda kuti chiedza chifambire mberi chakananga kutenderedzwa kwechiuno pane zvachinoita kuti chienderere mberi. kutungamira kwekutenderera kwechiuno.

Izvi zvinoreva kuti kana optical loop ichitenderera, chiedza chechiedza che optical loop chinoshanduka nenzira dzakasiyana-siyana dzemberi maererano nechiedza chechiedza chekuzorora.Nokushandisa shanduko iyi mu optical range, kana kupindira kunogadzirwa pakati pechiedza chiri kufambira mberi nenzira dzakasiyana-siyana kuti zviyere kutenderera kwekutenderera kwechiuno, interferometric fiber optic gyroscope inogona kugadzirwa.Kana iwe ukashandisa shanduko iyi munzira yeoptical ye loop kuti uwane kupindira pakati pechiedza chinotenderera muchiuno, ndiko kuti, nekugadzirisa resonant frequency yechiedza mune optical fiber loop uye nekuyera kutenderera kwekutenderera kwechiuno, resonant fiber optic gyroscope inogona kugadzirwa.
