Cob alt ferrite, CoFe2O4 (CoO·Fe2 O3), tseem yog siv rau nws cov ntawv thov magnetostrictive xws li sensors thiab actuators, ua tsaug rau nws qhov siab saturation magnetostriction (~ 200 qhov chaw ib lab).
Dab tsi yog cov ntaub ntawv tsim nyog rau magnetostrictive transducer?
Magnetostrictive transducers muaj ntau tus nickel (los yog lwm yam khoom siv magnetostrictive) daim hlaulos yog laminations teem nyob rau hauv parallel nrog ib tug ntug ntawm txhua lub laminate txuas rau hauv qab ntawm lub tank txheej txheem los yog lwm qhov chaw kom vibrated. Ib kauj ntawm cov hlau yog muab tso rau ib ncig ntawm cov khoom siv magnetostrictive.
Magnetostrictive transducer yog dab tsi?
Ib lub magnetostrictive transducer ua rau siv hom khoom siv hlau nplaum uas siv cov hlau nplaum sib nqus ua rau cov atoms ntawm cov khoom ua ke, tsim kom muaj kev hloov pauv ntawm qhov ntev ntawm qhov cov ntaub ntawv thiab yog li ua ib tug high-frequency mechanical vibration.
Cov khoom ntawm magnetostrictive sensor yog dab tsi?
Nws muaj tsib lub ntsiab ntawm cov magnetostrictive sensor: Waveguide, txoj hauj lwm hlau nplaum, hluav taws xob, strain pulse detection system, thiab damping module. Feem ntau, lub waveguide xaim yog nyob rau hauv ib lub hau tiv thaiv thiab txuas nrog rau cov cuab yeej uas tau ntsuas.
Cov khoom siv twg yog siv rau hauv tus pas nrig rau cov nyhuv magnetostriction?
Ib ironpas nrig muab tso rau hauv ib tug sib nqus teb qhia raws nws ntev stretches me ntsis nyob rau hauv ib tug qaug zog magnetic teb thiab cog lus me ntsis nyob rau hauv ib tug muaj zog magnetic teb. Mechanically stretching thiab compressing ib tug magnetized hlau pas inversely ua fluctuations nyob rau hauv lub magnetization ntawm tus pas nrig.
