ʻO nā mea magnetostrictive honua lāʻau
Ke hoʻopaneʻe ʻia kahi mea i loko o kahi māla magnetic, e hoʻolōʻihi a pōkole paha ia i ke ala o ka magnetization, i kapa ʻia ʻo magnetostriction.ʻO ka waiwai magnetostrictive o nā mea magnetostrictive maʻamau he 10-6-10-5 wale nō, he liʻiliʻi loa ia, no laila ua kaupalena ʻia nā kahua noi.Eia nō naʻe, i nā makahiki i hala iho nei, ua ʻike ʻia aia nā mea hoʻohuihui i loko o nā mea hoʻohui honua ʻokoʻa he 102-103 mau manawa ka nui ma mua o ka magnetostriction kumu.Hoʻomaopopo ka poʻe i kēia mea me ka magnetostriction nui e like me ka honua nui nui magnetostrictive mea.
ʻO nā mea magnetostrictive nui ka honua kahi ʻano mea hana hou i kūkulu ʻia e nā ʻāina ʻē i ka hopena o 1980s.ʻO ka mea nui e pili ana i nā pūhui intermetallic e pili ana i ka honua.ʻOi aku ka waiwai magnetostrictive o kēia ʻano mea ma mua o ka hao, nickel, a me nā mea ʻē aʻe.I nā makahiki i hala iho nei, me ka hoʻomau mau ʻana o ka hoʻemi ʻana o ke kumukūʻai o nā huahana magnetostrictive material nunui honua (REGMM) a me ka hoʻomau mau ʻana o nā kahua noi, ua piʻi ka ikaika o ka mākeke.
Hoʻomohala ʻana i nā mea hoʻoheheʻe honua Rare Earth Magnetostrictive
Ua hoʻomaka ʻo Beijing Iron and Steel Research Institute i kāna noiʻi ma ka ʻenehana hoʻomākaukau GMM ma mua.I ka makahiki 1991, ʻo ia ka mea mua ma Kina i hoʻomākaukau i nā pahu GMM a loaʻa iā ia kahi patent aupuni.Ma hope iho, ua hana hou ʻia ka noiʻi a me ka noi ʻana i nā transducers acoustic haʻahaʻa haʻahaʻa i lalo o ka wai, ka ʻike o ka fiber optic i kēia manawa, nā transducers welding ultrasonic mana kiʻekiʻe, a me nā mea ʻē aʻe, a me ka hana hoʻohui maikaʻi ʻana i ka ʻenehana GMM a me nā lako me nā kuleana waiwai naʻauao kūʻokoʻa a me ka mana hana makahiki. o nā tona i kūkulu ʻia.Ua hoʻāʻo ʻia ka mea GMM i hoʻomohala ʻia e Beijing University of Science and Technology ma 20 mau ʻāpana ma ka ʻāina a me ka honua, me nā hopena maikaʻi.Ua hoʻomohala pū ʻo Lanzhou Tianxing Company i kahi laina hana me ka mana hana makahiki o nā tona, a ua hana i nā mea nui i ka hoʻomohala ʻana a me ka hoʻohana ʻana i nā mea GMM.
ʻOiai ʻaʻole i lōʻihi ka hoʻomaka ʻana o ka noiʻi ʻana o Kina e pili ana i ka GMM, aia nō ia i ka hoʻomaka ʻana o ka ʻenehana a me ka hoʻomohala noi.I kēia manawa, ʻaʻole pono ʻo Kina e hana i nā holomua i ka ʻenehana hana GMM, nā lako hana, a me nā kumukūʻai hana, akā pono nō hoʻi e hoʻolilo i ka ikehu i ka hoʻomohala ʻana i nā mea noi noi.Hoʻopili nui nā ʻāina ʻē i ka hoʻohui ʻana i nā mea hana, nā ʻāpana, a me nā mea noi.ʻO ka mea ETREMA ma ʻAmelika Hui Pū ʻIa ʻo ia ka laʻana maʻamau o ka hoʻohui ʻana o ka noiʻi a me ka noiʻi mea noiʻi a me ke kūʻai aku.ʻO ka hoʻohana ʻana o GMM e pili ana i nā ʻano he nui, a ʻo ka poʻe i loko o ka ʻoihana a me ka poʻe ʻoihana pono e loaʻa i kahi hiʻohiʻona hoʻolālā, ʻike maka, a me ka ʻike kūpono i ka hoʻomohala ʻana a me ka hoʻohana ʻana i nā mea hana me nā manaʻo noiʻi ākea i ke kenekulia 21st.Pono lākou e nānā pono i nā ʻano hoʻomohala ma kēia kahua, e hoʻolalelale i kāna kaʻina hana ʻenehana, a hoʻolaha a kākoʻo i ka hoʻomohala ʻana a me ka hoʻohana ʻana i nā polokalamu noi GMM.
Pono o ka Rare Earth Magnetostrictive Materials
Loaʻa i ka GMM ka nui o ka hoʻololi ʻana i ka ikehu mechanical a me ka uila, ka nui o ka ikehu kiʻekiʻe, ka wikiwiki pane kiʻekiʻe, ka hilinaʻi maikaʻi, a me ke ʻano hoʻokele maʻalahi i ka lumi wela.ʻO kēia mau pono hana i alakaʻi i nā hoʻololi kipi i nā ʻōnaehana ʻike uila kahiko, nā ʻōnaehana ʻike, nā ʻōnaehana vibration, a pēlā aku.
Hoʻohana ʻana i nā mea hoʻohana ʻo Rare Earth Magnetostrictive Materials
I ka hoʻomohala wikiwiki ʻana o ka ʻenehana hou, ʻoi aku ma mua o 1000 mau mea GMM i hoʻokomo ʻia.ʻO nā wahi noi nui o GMM e pili ana i kēia:
1. I loko o ka ʻoihana pale, koa, a me ka aerospace, ua hoʻohana ʻia i ka kamaʻilio kelepona moku moku ma lalo o ka wai, nā ʻōnaehana hoʻohālikelike kani no nā ʻōnaehana ʻike / ʻike, mokulele, nā kaʻa honua, a me nā mea kaua;
2. I loko o ka ʻoihana uila a me nā ʻoihana ʻenehana hoʻokele ʻokoʻa kiʻekiʻe, hiki ke hoʻohana ʻia nā micro displacement drives i hana ʻia me ka hoʻohana ʻana i ka GMM no nā robots, ultra precision machining o nā mea kani kikoʻī, a me nā disk drive optical;
3. ʻO ka ʻepekema moana a me ka ʻoihana ʻenekinia waho, nā lako ana no ka hoʻohele ʻana o ka moana i kēia manawa, kiʻekiʻe o lalo o ka wai, wānana ōlaʻi, a me nā ʻōnaehana sonar haʻahaʻa haʻahaʻa mana kiʻekiʻe no ka hoʻouna ʻana a me ka loaʻa ʻana o nā hōʻailona leo;
4. Nā ʻoihana mīkini, textile, a me nā ʻoihana kaʻa, hiki ke hoʻohana ʻia no nā ʻōnaehana kaʻaahi, nā ʻōnaehana wahie / injection injection, a me nā kumu mana micro mechanical kiʻekiʻe;
5. ʻO ka ultrasound mana kiʻekiʻe, ka ʻaila a me nā ʻoihana lapaʻau, hoʻohana ʻia i ka kemika ultrasound, ka ʻenehana lapaʻau ultrasound, nā mea hoʻolohe, a me nā transducers kiʻekiʻe.
6. Hiki ke hoʻohana 'ia ma nā kula he nui e like me nā mīkini vibration, nā mīkini hana, nā mea hana wili, a me nā leo kūpaʻa kiʻekiʻe.
ʻO ka mea ʻike hoʻoneʻe magnetostrictive honua
