Nta thiab txiaj ntsig ntawm Tsheb Sib Nqus Sib Nqus
Txheem
Niaj hnub no, lub tshuab hluav taws xob hluav taws xob ncua ntawm lub tsheb txuas ntxiv ua kom zoo dua los ntawm cov kws tshaj lij los ntawm thoob plaws lub ntiaj teb, leej twg yuav tuaj yeem ua kom yooj yim dua rau cov neeg siv khoom, thiab cov kws tshaj lij automakers yuav pib siv cov thev naus laus zis no ntawm cov npe nrov tsheb.
Txij li thaum lub invention ntawm lub internal combustion engine, lub tsheb ncua kev kawm ntawv tsis tau hloov ntau npaum li cas - nws tau raug txhim kho raws li qhov tseeb ntawm lub caij tam sim no. Lub tshuab electromagnetic ncua kev kawm ntawv ntawm lub tsheb sawv cev rau ib tug structural breakthrough, tab sis yuav tsum tau kev txhim kho rau loj siv.
Dab tsi yog electromagnetic tsheb ncua
Lub luag hauj lwm uas lub tshuab electromagnetic ncua kev kawm ntawv ntawm lub tsheb ua tsis txawv ntawm cov pa caij nplooj ntoos hlav, torsion, caij nplooj ntoos hlav los yog pneumatic sawv daws yuav - nws txuas lub tsheb nrog txoj kev nto. Tsis zoo li cov kev ncua ib txwm muaj, cov hlau nplaum tsis muaj cov khoom qub thiab cov khoom siv: kev poob siab absorbers, stabilizing cov ntsiab lus, elastic rods.
Nyob rau hauv kev tsim nrog electromagnetic ncua kev kawm ntawv, txhua lub log yog nruab nrog ib tug tshwj xeeb khib uas ua hauj lwm ntawm ib tug poob siab absorber thiab ib tug elastic keeb ua ke. Cov ntaub ntawv thaum tsav tsheb los ntawm lub log nkag mus rau hauv chav tswj hluav taws xob, thiab nws tswj tau qhov kev ncua tam sim ntawd. Txhua yam uas cov khoom thiab cov khoom ua tau nyob rau hauv cov tshuab tshem tawm tau tshwm sim nyob rau hauv lub zog ntawm lub magnetic teb.
Yuav Ua Li Cas Sib Nqus Sib Nqus Ua Haujlwm
Txoj kev kawm ntawm electromagnetic - kev sib cuam tshuam ntawm hluav taws xob thiab sib nqus - teb tau coj cov kws tshawb fawb rau lub tswv yim ntawm kev tsim lub tsheb ya los ntawm huab cua. Kev siv txoj kev no yuav txhim kho txoj kev thauj mus los yam tsis muaj cov khoom siv tsis tsim nyog thiab kev sib dhos. Niaj hnub no, cov thev naus laus zis no tsuas yog ua tau nyob rau hauv cov dab neeg zoo heev, txawm hais tias lub hauv paus ntsiab lus ntawm electromagnetism tau siv rau hauv kev tsim lub tsheb ncua txij li xyoo 80s ntawm lub xyoo pua 20th.
Bose Electromagnetic Raug Tshem Tawm
Lub hauv paus ntsiab lus ntawm kev ua haujlwm ntawm kev sib nqus hlau nplaum yog ua raws li kev siv lub tshuab hluav taws xob uas ua haujlwm 2 lub luag haujlwm:
- Dampen los yog tiv thaiv kev vibrations. Ib feem ntawm kev ncua qhov twg cov hlau nplaum cuam tshuam ib leeg ua ib qho kev poob siab absorber thiab strut.
- Hloov torque los ntawm lub cav mus rau lub log. Ntawm no, cov cuab yeej ntawm repelling tib lub sib nqus ncej yog siv, thiab lub computer processor ntse siv lub peev xwm no elastic hais, thiab nws yuav luag xob laim sai.
Magnetic ncua kev kawm ntawv tsuas yog siv rau tag nrho lub tsheb, tsis zoo li ib txwm ncua kev kawm ntawv, qhov twg ib txoj cai yuav siv tau nyob rau hauv pem hauv ntej thiab lwm nyob rau hauv lub rov qab.
Pros thiab cons ntawm magnetic pendants
Txhua tus qauv tsim muaj qhov zoo thiab qhov tsis zoo.
| Yav tas los | Daim ntawv |
| Thaum tsis muaj hluav taws xob hluav taws xob, lub tshuab hluav taws xob sib nqus pib ua haujlwm zoo li cov khoom siv hluav taws xob. | Tus nqi siab dhau lawm |
| Cov tshuaj tiv thaiv tam sim ntawm txhua lub log rau kev hloov pauv hauv txoj kev. | |
| Muab uniform smoothness ntawm lub zog. | |
| Kev tsis sib xws ntawm txoj kev khiav tsis zoo, xws li pneumatics lossis springs, thiab lub kaw lus tuav lub tsheb, damping vibrations thiab nres lub cev yob. | |
| Kev caij tsheb yooj yim rau txhua tus neeg zaum hauv tsev. | |
| Kev siv lub tshuab muaj peev xwm siab tshaj plaws nrog kev siv hluav taws xob tsawg. |
Niaj hnub no, lub tshuab hluav taws xob hluav taws xob ncua ntawm lub tsheb txuas ntxiv ua kom zoo dua los ntawm cov kws tshaj lij los ntawm thoob plaws lub ntiaj teb, leej twg yuav tuaj yeem ua kom yooj yim dua rau cov neeg siv khoom, thiab cov kws tshaj lij automakers yuav pib siv cov thev naus laus zis no ntawm cov npe nrov tsheb.
Cov tuam ntxhab sab saum toj
Thawj lub tsheb nyob rau hauv lub 80s ntawm ib tug sib nqus cushion yog lub nroog Berlin tsheb ciav hlau magnetic levitation, los yog maglev, los ntawm cov lus Askiv qhia magnetic levitation. Lub tsheb ciav hlau yeej hovered hla lub monorail. Niaj hnub no, kev sib tsoo ntawm cov nroog loj nrog cov chaw tsim kho vaj tse tsis tso cai siv maglev hauv nws daim ntawv qub, tab sis muaj cov phiaj xwm los hloov nws mus rau cov qauv kev tsheb ciav hlau rau kev sib tshuam thiab kev sib tshuam hauv nroog.
Hauv kev lag luam automotive, peb hom electromagnetic suspensions yog siv.
Electromagnetic ncua kev kawm ntawv rau tsheb
Bose
Tus pioneer hauv kev tsim cov hlau nplaum raug tshem tawm yog Asmeskas tus kws tshawb fawb thiab ua lag luam Amar Bowes. Txij li thaum nws tau koom nrog kev txhim kho hauv thaj chaw ntawm lub suab thiab xov tooj cua, nws qhov kev ncua yog qhov tsim nyog raws li lub hauv paus ntsiab lus zoo ib yam - kev txav ntawm cov khoom siv hluav taws xob hauv cov hlau nplaum. Bose pendant muaj kev siv dav tshaj plaws ntawm txhua qhov, ua tsaug rau nws txoj kev yooj yim. Cov cuab yeej zoo ib yam li cov ntsiab lus ntawm lub tshuab hluav taws xob hluav taws xob xa mus rau hauv daim ntawv ntawm txoj kab ncaj nraim:
- nplhaib-zoo li tus hlau nplaum - stator;
- multipole bar hlau nplaum - rotor.
Lub Bose ncua kev kawm ntawv tuaj yeem teeb tsa kom thaum koj tsav tsheb ntawm qhov tsis xws luag, lub zog hluav taws xob tau tsim nyob rau hauv nws thiab xa mus rau lub roj teeb.
Delphi
Lub tuam txhab Asmeskas rau kev muab cov khoom rau General Motors cov nroj tsuag hauv kev tsim cov tshuab hluav taws xob hluav taws xob siv lub hauv paus ntsiab lus ntawm kev tswj kom zoo hauv kev txav. Nyob rau hauv no version, lub ntaus ntawv muaj xws li:
- shock absorber- yeeb nkab;
- kua nrog ferromagnetic hais coated nrog ib tug tshwj xeeb tshuaj uas tiv thaiv sticking;
- ib lub piston nrog lub taub hau uas tswj tag nrho cov system.
Qhov zoo ntawm cov qauv yog lub zog noj ntawm 20 watts. Cov tshuaj tiv thaiv ntawm cov khoom me me, los ntawm 5 mus rau 10 microns, zoo dua li cov hlau nplaum, yog li Delphi ncua kev ua haujlwm tau ua tiav sai dua li cov analogues. Cov kua dej hauv qhov poob siab absorber pib ua haujlwm raws li lub hauv paus ntsiab lus hydraulic yog tias chav tswj tau muab tua.
Delphi Kev Raug Txwv
SKF
Lwm hom kev hloov pauv hloov pauv yog tsim los ntawm Swedish engineering tuam txhab SKF. Cov khoom yog ib qho qauv uas muaj ib lub thawv uas muab ob lub electromagnets tso, thiab springs, raws li kev tuav pov hwm nyob rau hauv cov ntaub ntawv ntawm tsis ua hauj lwm ntawm hluav taws xob tswj chav tsev. Lub ntsiab tseem ceeb yog hloov cov khoom elastic.
Kev tawg ntawm ib qho khoom nyob rau hauv cov tsoos ncua kev kawm ua rau txo qis hauv lub tsheb hauv av clearance. SKF's magnetic suspension tiv thaiv qhov tshwm sim no, txawm tias thaum lub tshuab ua haujlwm ntev, lub ntsiab lus tseem ceeb ntawm lub cuab yeej siv los ntawm lub roj teeb.
Txhua lub tshuab hluav taws xob hluav taws xob yuav tsum muaj cov software nyuaj kom ua haujlwm ruaj khov ntawm qhov system. Rau kev siv serial, yuav tsum muaj ntau yam kev txhim kho thiab txo tus nqi.
