Zosowa zapadziko lapansi za magnetostrictive
Chinthu chikapangidwa ndi maginito mu gawo la maginito, chimatalikitsa kapena kufupikitsa kulowera kwa magnetization, komwe kumatchedwa magnetostriction.Mtengo wa magnetostrictive wazinthu zonse za magnetostrictive ndi 10-6-10-5 zokha, zomwe ndizochepa kwambiri, kotero minda yogwiritsira ntchito imakhala yochepa.Komabe, m'zaka zaposachedwa, zapezeka kuti pali zida za aloyi m'magawo osowa padziko lapansi omwe ndi 102-103 nthawi zazikulu kuposa maginito oyambira.Anthu amatchula izi ndi magnetostriction yayikulu ngati chinthu chosowa padziko lapansi chachikulu cha magnetostrictive.
Rare earth giant magnetostrictive materials ndi mtundu watsopano wazinthu zogwirira ntchito zomwe zangopangidwa kumene ndi mayiko akunja kumapeto kwa zaka za m'ma 1980.Makamaka amatanthauza osowa lapansi chitsulo zochokera intermetallic mankhwala.Zinthu zamtunduwu zimakhala ndi mtengo wokulirapo wa magnetostrictive kuposa chitsulo, faifi tambala, ndi zida zina.M'zaka zaposachedwa, ndi kutsika kosalekeza kwa mtengo wazinthu zamtundu wa rere earth giant magnetostrictive materials (REGMM) komanso kukula kosalekeza kwa minda yofunsira, kufunikira kwa msika kwakula kwambiri.
Kukula kwa Zosowa Zapadziko Lapansi Zopangira Magnetostrictive
Beijing Iron and Steel Research Institute idayamba kafukufuku wake paukadaulo wokonzekera GMM m'mbuyomu.Mu 1991, inali yoyamba ku China kukonza mipiringidzo ya GMM ndikupeza chilolezo cha dziko.Pambuyo pake, kufufuza kwina ndi ntchito kunachitika pa otsika pafupipafupi m'madzi acoustic transducers, CHIKWANGWANI chamawonedwe panopa kudziwika, mkulu-mphamvu akupanga kuwotcherera transducers, etc., ndi imayenera Integrated kupanga GMM luso ndi zipangizo ndi ufulu wodziimira aluntha katundu ndi pachaka kupanga mphamvu. matani anapangidwa.Zinthu za GMM zopangidwa ndi Beijing University of Science and Technology zayesedwa m'mayunitsi 20 mkati ndi kunja, ndi zotsatira zabwino.Lanzhou Tianxing Company nayenso anayamba mzere kupanga ndi mphamvu pachaka kupanga matani, ndipo wachita bwino kwambiri pa chitukuko ndi kugwiritsa ntchito zipangizo GMM.
Ngakhale kuti kafukufuku waku China pa GMM sanachedwe, akadali koyambirira kwa chitukuko cha mafakitale ndi ntchito.Pakadali pano, China sikuti imangofunika kuchita bwino paukadaulo wopanga wa GMM, zida zopangira, komanso mtengo wopangira, komanso ikufunika kuyika mphamvu pakupanga zida zogwiritsira ntchito.Mayiko akunja amaphatikiza kufunikira kwakukulu pakuphatikiza zida zogwirira ntchito, zida, ndi zida zogwiritsira ntchito.Zinthu za ETREMA ku United States ndiye chitsanzo chodziwika bwino cha kuphatikizika kwa kafukufuku wa zida ndi ntchito ndi malonda.Kugwiritsiridwa ntchito kwa GMM kumakhudza magawo ambiri, ndipo olowa m'makampani ndi amalonda ayenera kukhala ndi masomphenya abwino, kuwoneratu zam'tsogolo, komanso kumvetsetsa kokwanira pa chitukuko ndi kugwiritsa ntchito zida zogwirira ntchito zomwe zikuyembekezeka kugwiritsa ntchito kwambiri m'zaka za zana la 21.Ayenera kuyang'anitsitsa momwe chitukukochi chikuyendera, kufulumizitsa ndondomeko yake yopititsa patsogolo mafakitale, ndikulimbikitsa ndikuthandizira chitukuko ndi kugwiritsa ntchito zipangizo za GMM.
Ubwino Osowa Earth Magnetostrictive Zida
GMM ili ndi mphamvu zosinthira mphamvu zamakina komanso zamagetsi, kuchuluka kwamphamvu kwamphamvu, kuthamanga kwambiri, kudalirika kwabwino, komanso njira yosavuta yoyendetsera kutentha.Ndi zabwino izi zomwe zadzetsa kusintha kwazinthu zamakachitidwe azidziwitso zamakompyuta, makina omvera, makina ogwedezeka, ndi zina zotero.
Kugwiritsa Ntchito Zida Zamagetsi Zosawerengeka za Earth
M'zaka zaukadaulo zomwe zikukula mwachangu, zida zopitilira 1000 za GMM zidayambitsidwa.Magawo akuluakulu ogwiritsira ntchito GMM ndi awa:
1. M'mafakitale achitetezo, ankhondo, komanso oyendetsa ndege, amagwiritsidwa ntchito pazolumikizana zam'madzi zam'madzi zam'madzi, zoyeserera zomveka zowunikira / kuzindikira, ndege, magalimoto apamtunda, ndi zida;
2. M'makampani opanga zamagetsi ndi mafakitale apamwamba kwambiri, makina oyendetsa ma micro displacement opangidwa pogwiritsa ntchito GMM angagwiritsidwe ntchito ngati maloboti, makina opangidwa bwino kwambiri a zida zosiyanasiyana zolondola, ndi ma drive optical disk;
3. Sayansi ya m'nyanja ndi makampani opanga uinjiniya wa m'mphepete mwa nyanja, zida zofufuzira zogawira nyanja zam'madzi, malo owonera pansi pamadzi, kulosera za zivomezi, ndi makina amphamvu otsika kwambiri otumizira ndi kulandira ma siginecha;
4. Makampani opanga makina, nsalu, ndi magalimoto, omwe angagwiritsidwe ntchito popangira ma brake system, makina ojambulira mafuta / jakisoni, komanso magwero amphamvu amagetsi ang'onoang'ono;
5. Ma ultrasound amphamvu kwambiri, mafakitale a petroleum ndi azachipatala, omwe amagwiritsidwa ntchito mu chemistry ya ultrasound, teknoloji yachipatala ya ultrasound, zothandizira kumva, ndi transducers amphamvu kwambiri.
6. Itha kugwiritsidwa ntchito m'magawo ambiri monga makina ogwedera, makina omanga, zida zowotcherera, komanso mawu omvera kwambiri.
