Rare ntiaj teb magnetostrictive cov ntaub ntawv
Thaum ib yam khoom yog magnetized nyob rau hauv magnetic teb, nws yuav elongate los yog luv luv nyob rau hauv cov kev taw qhia ntawm magnetization, uas yog hu ua magnetostriction. Tus nqi magnetostrictive ntawm cov khoom siv magnetostrictive tsuas yog 10-6-10-5, uas yog tsawg heev, yog li daim ntawv thov teb kuj raug txwv. Txawm li cas los xij, nyob rau xyoo tas los no, nws tau pom tias muaj cov khoom siv hlau hauv cov hlau tsis tshua muaj hauv ntiaj teb uas yog 102-103 npaug loj dua li qhov qub magnetostriction. Cov neeg xa mus rau cov khoom siv nrog magnetostriction zoo li cov khoom siv tsis tshua muaj ntiaj teb loj magnetostrictive.
Tsis tshua muaj lub ntiaj teb loj magnetostrictive cov ntaub ntawv yog ib yam tshiab ntawm cov khoom siv ua haujlwm tshiab tsim los ntawm txawv teb chaws nyob rau xyoo 1980s. Feem ntau yog hais txog lub ntiaj teb tsis tshua muaj hlau raws li intermetallic compounds. Cov khoom siv no muaj cov nqi magnetostrictive ntau dua li hlau, npib tsib xee, thiab lwm yam ntaub ntawv. Nyob rau hauv xyoo tas los no, nrog kev txo qis ntawm tus nqi ntawm cov khoom tsis tshua muaj hauv ntiaj teb loj magnetostrictive cov khoom (REGMM) thiab kev nthuav dav ntawm daim ntawv thov kev lag luam, kev lag luam xav tau nce ntxiv.
Kev loj hlob ntawm Rare Earth Magnetostrictive Materials
Beijing Iron thiab Steel Research Institute tau pib nws txoj kev tshawb fawb ntawm GMM npaj tshuab ua ntej. Xyoo 1991, nws yog thawj zaug hauv Suav teb los npaj GMM tuav thiab tau txais lub teb chaws patent. Tom qab ntawd, kev tshawb fawb ntxiv thiab daim ntawv thov tau ua tiav ntawm qhov tsawg zaus underwater acoustic transducers, fiber optic tam sim no nrhiav tau, high-power ultrasonic vuam transducers, thiab lwm yam, thiab ua tau zoo integrated zus tau tej cov GMM technology thiab cov khoom uas muaj kev ywj pheej kev txawj ntse txoj cai thiab ib xyoos twg muaj peev xwm ntau lawm. ntawm tons tau tsim. Cov khoom siv GMM tsim los ntawm Beijing University of Science thiab Technology tau raug sim hauv 20 units ob qho tib si hauv tebchaws thiab thoob ntiaj teb, nrog cov txiaj ntsig zoo. Lanzhou Tianxing Lub Tuam Txhab kuj tau tsim cov kab ntau lawm nrog lub peev xwm tsim khoom txhua xyoo ntawm tons, thiab tau ua tiav qhov tseem ceeb hauv kev txhim kho thiab kev siv ntawm GMM cov cuab yeej.
Txawm hais tias Tuam Tshoj txoj kev tshawb fawb ntawm GMM pib tsis lig dhau lawm, nws tseem nyob rau hauv nws cov theem pib ntawm industrialization thiab kev tsim kho daim ntawv thov. Tam sim no, Tuam Tshoj tsis yog tsuas yog yuav tsum tau ua kom dhau los ntawm GMM cov cuab yeej tsim khoom, cov cuab yeej tsim khoom, thiab cov nqi tsim khoom, tab sis tseem yuav tsum tau nqis peev lub zog hauv kev tsim cov khoom siv hauv cov khoom siv. Cov teb chaws txawv teb chaws tseem ceeb heev rau kev sib koom ua ke ntawm cov khoom siv, cov khoom siv, thiab cov khoom siv siv. Cov khoom siv ETREMA hauv Tebchaws Meskas yog qhov piv txwv zoo tshaj plaws ntawm kev sib koom ua ke ntawm cov khoom siv thiab cov ntawv thov kev tshawb fawb thiab kev muag khoom. Daim ntawv thov ntawm GMM suav nrog ntau thaj chaw, thiab cov neeg ua lag luam sab hauv thiab cov neeg ua lag luam yuav tsum muaj lub zeem muag zoo, kev pom, thiab kev nkag siab txaus ntawm kev txhim kho thiab kev siv cov ntaub ntawv ua haujlwm nrog rau daim ntawv thov dav dav hauv lub xyoo pua 21st. Lawv yuav tsum ua tib zoo saib xyuas txoj kev txhim kho hauv daim teb no, ua kom nws cov txheej txheem kev lag luam, thiab txhawb nqa thiab txhawb nqa kev txhim kho thiab kev siv ntawm GMM daim ntawv thov khoom siv.
Qhov zoo ntawm Rare Earth Magnetostrictive Materials
GMM muaj cov tshuab hluav taws xob thiab hluav taws xob hloov hluav taws xob siab, siab zog ceev, siab teb ceev, kev ntseeg tau zoo, thiab kev tsav tsheb yooj yim ntawm chav tsev kub. Nws yog cov kev ua tau zoo uas tau ua rau muaj kev hloov pauv hloov pauv hauv cov ntaub ntawv xov xwm hluav taws xob ib txwm muaj, ntsuas qhov system, vibration systems, thiab lwm yam.
Daim ntawv thov ntawm Rare Earth Magnetostrictive Materials
Nyob rau hauv lub xyoo pua tshiab ntawm kev tsim kho sai sai, ntau tshaj 1000 GMM cov cuab yeej tau qhia. Cov cheeb tsam tseem ceeb ntawm GMM suav nrog cov hauv qab no:
1. Nyob rau hauv kev tiv thaiv, tub rog, thiab aerospace industries, nws yog siv rau underwater nkoj mobile kev sib txuas lus, suab simulation systems rau nrhiav/ntseeg systems, aircraft, av tsheb, thiab riam phom;
2. Nyob rau hauv kev lag luam hluav taws xob thiab high-precision tsis siv neeg tswj kev lag luam, micro displacement drives manufactured siv GMM yuav siv tau rau robots, ultra precision machining ntawm ntau yam precision instruments, thiab optical disk drives;
3. Marine science thiab offshore engineering kev lag luam, cov cuab yeej tshawb fawb rau kev faib dej hiav txwv tam sim no, underwater topography, av qeeg kwv yees, thiab high-power low-frequency sonar systems rau kev xa thiab tau txais cov teeb liab acoustic;
4. Machinery, textile, thiab automotive manufacturing industries, uas yuav siv tau rau tsis siv neeg nres tshuab, roj / txhaj tshuaj tshuab, thiab high-kev ua tau zoo micro mechanical zog qhov chaw;
5. Lub zog hluav taws xob siab siab, roj av thiab kev lag luam kho mob, siv rau hauv kev siv hluav taws xob hauv tshuab hluav taws xob, kev siv tshuab ultrasound, kev hnov lus, thiab cov tshuab hluav taws xob siab.
6. Nws tuaj yeem siv rau hauv ntau qhov chaw xws li kev co tshuab, kev tsim kho tshuab, cov khoom siv vuam, thiab cov suab nrov siab.
