Rau kev siv hlau nplaum, txhua tus neeg them nyiaj zoo rau kev nyiam ntawm cov hlau nplaum. Lub zog quab yuam ntawm cov hlau nplaum tuaj yeem suav nrog (rub lub tshuab xam zauv). Cov qauv hauv qab no tuaj yeem siv rau kev siv. Txawm li cas los xij, nws yuav tsum tau muab sau tseg tias lub neej ntawd tej yam kev mob ntawm lub mis yog zoo tagnrho, uas yog, lub magnetic teb faib yog heev uniform. Qhov sib nqus permeability ntawm cov khoom nyiam yog siab heev (tsis muaj zog hlau nplaum). Cov ntaub ntawv xws li 300 series stainless hlau thiab lwm yam ferrous alloys tsis siv), lub thickness thiab adsorption cheeb tsam yog txaus (nce lub thickness thiab cheeb tsam suction quab yuam yuav tsis nce, uas yog, tsis hais magnetic to), txawm li ntawd los, cov xam. tus nqi tseem tsuas yog siv los ua Kev siv, nws tsis tuaj yeem siv los ua kev xam kom raug.
(Ntawm lawv, S sawv cev rau thaj chaw adsorption, B sawv cev rau huab cua sib nqus sib nqus flux ceev, thiab μ0 yog lub tshuab nqus tsev magnetic permeability (uas yog qhov tsis tu ncua, μ0=4π * 10-7 ))
Yuav Ua Li Cas Txhim Kho Qhov Kev Txaus Siab Ntawm Magnets?
1. Ua kom qhov chaw adsorption
Cov khoom yuav tsum tau nyiam yuav tsum tsawg kawg yog npog qhov adsorption nto ntawm cov hlau nplaum, thiab cov khoom thickness tuaj yeem nce ntxiv yog tias muaj kev tso cai.
Thaum Lub Magnet Txaus Ntsig Hlau Phaj:
Qhov loj dua qhov adsorption cheeb tsam ntawm cov hlau phaj thiab cov hlau nplaum, lub zog nqus ntawm cov hlau nplaum thiab cov hlau phaj ntau dua. Thaum lub adsorption cheeb tsam sib npaug rau thaj tsam ntawm cov hlau nplaum, qhov kev nyiam ntawm lub zog nqus kom nce yuav maj mam qeeb. Thaum lub phaj hlau loj txaus, nws yuav ua rau thaj tsam ntawm lub phaj hlau tsis tuaj yeem txhim kho lub zog nqus;
Thaum thaj tsam ntawm cov phaj hlau yog tib yam, thaum lub thickness ntawm cov phaj hlau yog nyias, ua kom cov thickness ntawm cov phaj hlau tuaj yeem ua rau kom lub zog nqus. Thaum lub phaj hlau yog tuab, qhov nce hauv qhov nqus tau los ntawm kev nce lub thickness ntawm cov phaj hlau yuav maj mam nce mus txog thaum tsis muaj kev txhim kho.
2. Ua kom cov pa sib nqus sib nqus Flux ceev
Los ntawm daim duab sib nqus teb simulation, peb tuaj yeem pom tias tom qab cov hlau nplaum hloov mus rau bipolar magnetization, cov hlau nplaum sib nqus tau txo qis, thiab feem ntau ntawm cov kab hlau nplaum sib nqus tsim ib lub voj voog kaw sib nqus hauv cov hlau adsorbed.
Yog hais tias tus naj npawb ntawm cov ncej yog ntxiv thiab ib daim ntawv hlau nplaum ntxiv rau hauv qab ntawm cov hlau nplaum, cov hlau nplaum yuav raug txo kom tsawg thiab lub zog nqus yuav raug txhim kho ntxiv.
Cov qauv tsim tam sim no ntawm cov khoom sib nqus yog kom ua tiav kev siv cov khoom sib nqus. Los ntawm kev tsim ntawm ntau tus ncej sib nqus circuits lossis Halbach magnetic circuits, los yog nrog kev taw qhia ntawm qee cov ntaub ntawv nrog siab sib nqus permeability, lub magnetic teb tuaj yeem dhau los ntawm cov khoom ntau li ntau tau. Kev nyiam cov khoom tsim ib lub voj kaw ntawm lub magnetic circuit. Cov ntawv thov ib txwm muaj xws li:
Roj hmab hlau nplaum yog tsim los rau ntau theem magnetization, ib txhia yog ob-sided multi-ncej, thiab ib txhia yog ib leeg-sided multi-ncej. Cov hlau nplaum kev ua tau zoo ntawm cov hlau nplaum roj hmab yog qhov tsawg heev, tab sis tom qab ntau tus ncej sib nqus hluav taws xob tsim, cov hlau nplaum sib nqus tau ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom. Magnetic to yog heev me me thaum lub sij hawm adsorption, ua rau cov nyhuv adsorption zoo dua;
Cov khoom siv sib nqus xws li lub qhov rooj nqus cov cuab yeej yog coj los ntawm cov ntawv sib nqus permeable. Thaum adsorbing, lub magnetic Circuit Court yog yuav luag tsim los ntawm cov khoom yuav adsorbed. Nyob rau hauv txoj kev no, kev siv tus nqi ntawm cov magnetic teb yog siab heev. Lub intuitive kev paub yog hais tias ntawm ib tug me me sib nqus nqus tshuab. , lub zog nqus yog loj heev thaum nyob rau hauv kev sib cuag ncaj qha.
