1. Txhim Kho Kev Tsim Kho Electromagnetic Coil

Lub kauj solenoid tsim lub zog sib nqus los ua kom lub valve ua haujlwm. Cov kev txhim kho tseem ceeb suav nrog:

• Nce Coil Tig: Ntxiv ntau cov xov hlau ua rau muaj zog magnetic flux, txo qhov kev ncua sijhawm ua haujlwm14.

• Cov Khoom Siv Uas Tsis Muaj Kev Tiv Thaiv: Siv cov hlau tooj liab uas muaj cov khoom siv siab ua rau txo qhov poob hluav taws xob thiab tsim cua sov, ua kom muaj kev ua haujlwm ruaj khov3.

• Kev Teeb tsa Dual-CoilIb txoj kev tshawb fawb los ntawm Jiang et al. tau ua tiav lub sijhawm teb 10 ms (los ntawm 50 ms) siv kev tsim ob-winding, zoo tagnrho rau cov ntawv thov aerospace uas xav tau kev ua haujlwm ceev heev4.

Kev Kawm Txog Cov Ntaub NtawvLub valve uas npaj txhij rau kev ya dav hlau txo lub sijhawm teb los ntawm 80% los ntawm kev ua kom zoo dua ntawm lub kauj geometry thiab txo qhov inductance4.

2. Txhim kho cov qauv thiab cov txheej txheem ntawm lub valve

Kev tsim kho tshuab ncaj qha cuam tshuam rau qhov ceev ntawm kev ua haujlwm:

• Cov Plungers Sib DuaKev txo qhov hnyav uas txav mus los (piv txwv li, titanium alloys) txo qhov inertia, ua rau muaj kev txav mus los sai dua314.

• Kev Kho Kom Zoo Nkauj Caij Nplooj Ntoos Hlav: Kev sib phim lub caij nplooj ntoos hlav lub zog rau lub zog sib nqus ua kom kaw sai yam tsis muaj overshoot3.

• Cov Lus Qhia Txog Kev Sib Txhuam QisCov tes tsho valve uas tau txhuam los yog cov txheej ceramic txo qhov lo, qhov no tseem ceeb rau kev siv high-cycle1.

Piv txwv: Cov li qub CKD tau txhim kho cov lus teb los ntawm 30% siv cov tub ntxhais valve tapered thiab kev ua kom zoo dua lub caij nplooj ntoos hlav preload3.

3. Kev Txhim Kho Cov Teeb Liab Tswj Xyuas Siab Tshaj Plaws

Cov kev tswj hwm muaj feem cuam tshuam rau cov lus teb:

• PWM (Kev Hloov Pauv Dav ntawm Lub Plawv)Kev kho cov voj voog ua haujlwm thiab lub sijhawm ncua sijhawm ua rau qhov kev ua haujlwm raug dua. Ib txoj kev tshawb fawb xyoo 2016 txo lub sijhawm teb rau 15 ms siv 12V tsav hluav taws xob thiab 5% PWM duty8.

• Cov voj voog siab tshaj plaws thiab tuav: Cov pulses high-voltage thawj zaug ua rau lub valve qhib sai dua, ua raws li qhov voltage qis dua kom txo tau kev siv hluav taws xob14.

Kev Siv Cov Ntaub Ntawv Los Ua Txoj HaujlwmTxoj kev ntsuas qhov chaw teb (RSM) txheeb xyuas qhov voltage, qeeb, thiab kev ua haujlwm zoo tshaj plaws, ua rau lub sijhawm teb luv dua 40% hauv cov tshuab tsuag ua liaj ua teb8.

4. Kev Xaiv Khoom Siv Rau Kev Ruaj Khov Thiab Kev Ceev

Cov kev xaiv khoom siv sib npaug qhov ceev thiab lub neej ntev:

• Cov Hlau Uas Tiv Thaiv Kev Kub Ntxhov: Cov hlau tsis xeb (316L) lossis PEEK cov tsev tiv taus cov xov xwm hnyav yam tsis muaj kev ua tau zoo poob qis114.

• Cov Cores Uas Muaj Permeability Siab: Cov ntaub ntawv ferromagnetic xws li permalloy txhim kho kev ua haujlwm ntawm magnetic, txo lub sijhawm siv zog 4.

5. Kev Tswj Xyuas Ib puag ncig thiab Fais Fab

Cov yam sab nraud yuav tsum tau txo qis:

• Kev Muab Fais Fab Ruaj Khov: Qhov hloov pauv ntawm qhov hluav taws xob > 5% tuaj yeem ncua kev teb; cov hloov pauv DC-DC uas tswj hwm kom ntseeg tau tias muaj kev sib xws314.

• Kev Tswj Xyuas Kub: Cov dab dej kub lossis cov kauj ruaj khov tiv thaiv kev hloov pauv tsis kam hauv qhov chaw kub siab14.

Daim Ntawv Thov Kev Lag LuamLub tshuab ntim khoom ua tiav 99.9% lub sijhawm ua haujlwm los ntawm kev koom ua ke cov tsav tsheb uas them rau qhov kub thiab txias3.
