Amakosa 5 yo Kwirinda Mugihe Ukoresha Magnet U U ya Neodymium

U-shusho ya neodymium magnet ni imbaraga zikomeye. Igishushanyo cyabo cyihariye cyibanda kumaseti akomeye cyane mumwanya muto, bigatuma biba byiza mubisabwa nka magnetiki chucks, sensor yihariye, moteri yumuriro mwinshi, hamwe nibikoresho bikomeye. Ariko, imikorere yabo ikomeye nuburyo bugoye nabyo bituma bigorana kubitunganya. Ikosa rimwe rishobora kuganisha ku guta amafaranga, gutinda k'umushinga, cyangwa no gutsindwa biteje akaga.

 

Irinde aya makosa 5 akomeye kugirango umenye neza imiterere ya U-ya neodymium ya magneti ikora neza kandi neza:

 

Ikosa # 1: Kwirengagiza Ibikoresho Byoroheje hamwe na Stress

 

Ikibazo:Magneti ya Neodymium (cyane cyane amanota akomeye nka N52) asanzwe avunika, nka farashi nziza. Inguni zikarishye za U-shusho zitera ingingo yibanze yibitekerezo. Kunanirwa kubara ubwo bugome mugihe ugaragaza ibipimo, kwihanganira, cyangwa gukemura ibisabwa birashobora kugushikana kumeneka cyangwa kuvunika ibiza mugihe cyo gukora, magnetisiyasi, kohereza, ndetse no kwishyiriraho.

Igisubizo:

Kugaragaza Radiyo Nini:Saba binini binini bishoboka imbere ya radiyo (R) igishushanyo cyawe gishobora gukora. Impagarike ya dogere 90 yunamye ni oya-oya.

Hitamo icyiciro gikwiye:Rimwe na rimwe, urwego rwo hasi gato (urugero, N42 aho kuba N52) rushobora gutanga imbaraga zo kuvunika neza utitanze imbaraga zikenewe cyane.

Menyesha ibikenewe mu gukemura:Menya neza ko uwagukoreye yumva uburyo magnesi zizakorwa kandi zigashyirwaho. Bashobora gusaba gupakira ibintu cyangwa ibikoresho.

Irinde amaguru yoroheje:Amaguru yoroheje cyane ugereranije nubunini n'imbaraga za magneti arashobora kongera cyane ibyago byo kuvunika.

 

Ikosa # 2: Gushushanya utitaye ku cyerekezo cya magnetisation

 

Ikibazo:Magnet ya NdFeB ikura imbaraga zayo mu gukwega icyerekezo runaka nyuma yo gucumura. Kuri magnet U U, inkingi hafi ya zose kumpera yamaguru. Niba ugaragaje imiterere cyangwa ubunini bugoye bibuza magnetisiyonike guhuza neza na pole mumaso, magnet ntizagera kumbaraga nini ya magnetisme cyangwa irashobora kuvamo amakosa ya magnetisation.

Igisubizo:

Baza hakiri kare:Muganire ku gishushanyo cyawe nuwakoze magnet mbere yo kurangiza. Kandi ubaze ibijyanye na magnetizing fixture ibisabwa hamwe nimbibi.

Shyira imbere isura ya pole:Menya neza ko igishushanyo cyemerera uburyo busobanutse, butabujijwe kugera kuri magnetizing coil hejuru yubuso bwa buri pole.

Sobanukirwa icyerekezo:Vuga neza icyerekezo cyifuzwa cya magnetisiyonike (muburyo bwanyuze kuri pole) mubisobanuro byawe.

 

Ikosa # 3: Gupfobya akamaro ko kwihanganira (cyangwa kubashyiraho cyane)

 

Ikibazo:Magneteri Nd yagabanutse mugihe cyo gukora, bigatuma gukora nyuma yo gucumura bigoye kandi biteje akaga (reba Ikosa # 1!). Gutegereza "kwihanganira ibyuma" kwihanganira (± 0.001 muri.) Ntibishoboka kandi bihenze cyane. Ibinyuranye, kwerekana kwihanganira ubugari cyane (± 0.1 muri.) Birashobora kuvamo rukuruzi idashobora gukoreshwa munteko yawe.

Igisubizo:

Sobanukirwa n'ibipimo by'inganda:Sobanukirwa no kwihanganira "gucumura" bisanzwe kuri magneti ya NdFeB (mubisanzwe ± 0.3% kugeza ± 0.5% yubunini, hamwe no kwihanganira byibuze ± 0.1 mm cyangwa 0.005 muri.).

Jya ushyira mu gaciro:Kugaragaza kwihanganira gukomeye gusa aho ari ngombwa gukora, nko guhuza ibice. Mu bindi bihe, kwihanganira hasi birashobora kuzigama ibiciro no kugabanya ingaruka.

Muganire ku gusya:Niba ubuso bugomba kuba busobanutse neza (urugero, isura yuzuye), vuga ko gusya bisabwa. Ibi birashobora kongera ikiguzi ningaruka zikomeye, koresha rero mugihe bibaye ngombwa. Menya neza ko uwabikoze azi ibice bisaba gusya.

 

Ikosa # 4: Kwirengagiza kurengera ibidukikije (coatings)

Ikibazo:Magnette ya neodymium yangirika vuba iyo ihuye nubushuhe, ubushuhe, cyangwa imiti imwe n'imwe. Ruswa itangirira ku mfuruka zoroshye kandi itesha agaciro imikorere ya magneti hamwe nuburinganire bwimiterere. Guhitamo igifuniko kitari cyo, cyangwa ukeka ko igifuniko gisanzwe gihagije kubidukikije bikaze, birashobora gutuma unanirwa hakiri kare.

Igisubizo:

Ntuzigere wirengagiza impuzu:Bare NdFeB ntabwo ikwiranye na magnesi ikora.

Impuzu zigomba guhuza ibidukikije:Isahani isanzwe ya nikel-umuringa-nikel (Ni-Cu-Ni) irakwiriye gukoreshwa murugo. Kubidukikije bitose, bitose, hanze, cyangwa byatewe nimiti, vuga igifuniko gikomeye nka:

Epoxy / Parylene:Ubushuhe buhebuje hamwe n’imiti irwanya imiti, hamwe n’amashanyarazi.

Zahabu cyangwa zinc:kubirwanya ruswa yihariye.

Epoxy yibyibushye:kubidukikije bikaze.

Kugaragaza imbere mu mfuruka:Shimangira ko igifuniko kigomba gutanga ubwishingizi bumwe, cyane cyane kumuvuduko mwinshi imbere mu mfuruka ya U-shusho. Baza ibijyanye n'ingwate yo gukora.

Suzuma ibizamini byo gutera umunyu:Niba kurwanya ruswa ari ingenzi, vuga umubare wamasaha yo gupima umunyu (urugero, ASTM B117) magnet yatwikiriye agomba kunyura.

 

Ikosa # 5: Gusiba Icyiciro cya Prototype

Ikibazo:Hariho ingaruka zo gusimbuka murutonde runini rushingiye kuri moderi ya CAD cyangwa urupapuro rwonyine. Ibintu nyabyo-isi nko gukwirakwiza magnetique, gukwirakwiza kwukuri kwibigize, gukemura intege nke, cyangwa imikoranire itunguranye irashobora kugaragara gusa hamwe nicyitegererezo cyumubiri.

 

Igisubizo:

Kora prototypes: bije hanyuma ushimangire kubice bito bya prototypes mbere.

Ikizamini gikomeye: Subject prototypes kumiterere-yisi:

Menya neza imikorere n'imikorere mu nteko.

Ibipimo nyabyo-bikurura ibipimo (bihuye nibyo ukeneye?).

Gukemura ibizamini (bizarokoka kwishyiriraho?).

Ibizamini byo kwangiza ibidukikije (niba bishoboka).

Iterate nkuko bikenewe: Koresha ibitekerezo bya prototype kugirango uhindure ibipimo, kwihanganira, gutwikira, cyangwa amanota mbere yo kwiyemeza gutanga umusaruro uhenze.
