Rare Earth magnetostrictive zvinhu
Kana chinhu chine magineti mundima yemagineti, chinorebesa kana kupfupika munzira yemagnetization, iyo inonzi magnetostriction.Iyo magnetostrictive kukosha kweyakajairwa magnetostrictive zvinhu ingori 10-6-10-5, iyo idiki kwazvo, saka minda yekushandisa ishoma.Nekudaro, mumakore achangopfuura, zvakaonekwa kuti kune alloy zvinhu mune isingawanzo pasi alloys ayo ari 102-103 nguva yakakura kupfuura yekutanga magnetostriction.Vanhu vanotaura nezvechinhu ichi chine magnetostriction yakakura seisingawanzo pasi giant magnetostrictive material.
Rare Earth giant magnetostrictive materials imhando itsva yezvinhu zvinoshanda zvichangobva kuvandudzwa nenyika dzekunze mukupera kwema1980.Zvinonyanya kureva zvisingawanzo pasi iron based intermetallic compounds.Rudzi urwu rwezvinhu rune yakakura kwazvo magnetostrictive kukosha kupfuura iron, nickel, uye zvimwe zvinhu.Mumakore achangopfuura, nekudzikiswa kunoramba kuchiita mutengo weasingawanzo pasi giant magnetostrictive materials (REGMM) zvigadzirwa uye nekuenderera mberi kwekuwedzera kweminda yekushandisa, kudiwa kwemusika kwawedzera kusimba.
Kuvandudzwa kweRare Earth Magnetostrictive Materials
Beijing Iron uye Steel Research Institute yakatanga tsvagiridzo yayo paGMM yekugadzirira tekinoroji kare.Muna 1991, yaive yekutanga muChina kugadzirira mabhawa eGMM uye kuwana patent yenyika.Mushure mezvo, kumwe kutsvagisa uye kushandiswa kwakaitwa pazasi-frequency pasi pemvura acoustic transducers, fiber optic yekuona ikozvino, yakakwirira-simba ultrasonic welding transducers, nezvimwewo, uye inobudirira yakabatanidzwa kugadzirwa kweGMM tekinoroji nemidziyo ine yakazvimirira yehungwaru kodzero uye yegore rekugadzira kugona. yematani akagadzirwa.Zvinhu zveGMM zvakagadziridzwa neBeijing University of Science and Technology zvakaedzwa muzvikamu makumi maviri mukati nekunze kwenyika, nemhedzisiro yakanaka.Kambani yeLanzhou Tianxing yakagadzirawo tambo yekugadzira ine huwandu hwegore hwekugadzira matani, uye yakaita zvakakosha mukuvandudza nekushandiswa kwemidziyo yeGMM.
Kunyangwe tsvagiridzo yeChina paGMM yakatanga isati yanonoka, ichiri mumatanho ekutanga ekusimudzira maindasitiri nekusimudzira mashandisirwo.Parizvino, China haingofanire chete kuita budiriro mukugadzira tekinoroji yeGMM, michina yekugadzira, uye mutengo wekugadzira, asi inodawo kuisa simba mukuvandudza kwemidziyo yekushandisa.Nyika dzekunze dzinoisa kukosha kukuru mukubatanidzwa kwezvinhu zvinoshanda, zvikamu, uye zvishandiso zvekushandisa.Iyo ETREMA zvinhu muUnited States ndiyo yakajairika muenzaniso wekubatanidzwa kwezvinhu uye mashandisirwo echishandiso kutsvagisa nekutengesa.Kushandiswa kweGMM kunosanganisira minda yakawanda, uye vemukati meindasitiri nevamabhizinesi vanofanirwa kuve nechiratidzo chehurongwa, kufanoona, uye kunzwisisa kwakakwana kwekusimudzira nekushandiswa kwezvinhu zvinoshanda zvine tarisiro yakafara yekushandiswa muzana ramakore re21.Vanofanirwa kunyatso tarisisa mafambiro ebudiriro mundima iyi, kusimudzira maitiro ayo ekusimudzira maindasitiri, uye kusimudzira nekutsigira kusimudzira nekushandiswa kweGMM application zvishandiso.
Zvakanakira Rare Earth Magnetostrictive Materials
GMM ine yakakwira mechanicha uye yemagetsi simba rekushandura chiyero, yakakwira simba density, yakakwirira yekupindura kumhanya, kuvimbika kwakanaka, uye nyore kutyaira modhi pakamuri tembiricha.Ndiwo mabhenefiti ekuita aya akatungamira kushanduko dzechinyakare dzemagetsi ruzivo masisitimu, masisitimu ekunzwa, vibration masisitimu, zvichingodaro.
Kushandiswa kweRare Earth Magnetostrictive Materials
Munguva inokurumidza kukura yezana ramakore retekinoroji, zvinopfuura 1000 GMM zvishandiso zvakaunzwa.Iwo makuru ekushandisa nzvimbo dzeGMM anosanganisira anotevera:
1. Muchidziviriro, mauto, uye maindasitiri emuchadenga, inoshandiswa kune ngarava yepasi pemvura kutaurirana kwemafoni, masisitimu ekuenzanisa ekuona / kuona masisitimu, ndege, mota dzepasi, uye zvombo;
2. Muindasitiri yemagetsi uye yakakwirira-chaiyo otomatiki kudzora tekinoroji maindasitiri, micro displacement madhiraivha anogadzirwa achishandisa GMM anogona kushandiswa kumarobhoti, ultra precision machining ezviridzwa zvakasiyana-siyana, uye optical disk drives;
3. Marine sainzi neindasitiri yeinjiniya yekunze, midziyo yekuongorora yekugovera gungwa ikozvino, nzvimbo yepasi pemvura, kufanotaura kwekudengenyeka kwenyika, uye masimba epamusoro-soro-yepasi-frequency sonar masisitimu ekutumidzira nekugamuchira masaini anonzwika;
4. Michina, machira, uye maindasitiri ekugadzira mota, ayo anogona kushandiswa otomatiki mabhureki masisitimu, mafuta / jekiseni majekiseni masisitimu, uye yakakwirira-inoshanda micro mechanical magetsi masosi;
5. High power ultrasound, petroleum uye maindasitiri ezvokurapa, anoshandiswa mu ultrasound chemistry, ultrasound medical technology, kunzwa kunzwa, uye high-power transducers.
6. Inogona kushandiswa muminda yakawanda senge vibration muchina, michina yekuvaka, welding midziyo, uye yakakwirira kutendeka odhiyo.
