Iivalvu ezincinci ze-solenoidzizinto ezibalulekileyo kwiinkqubo zokuzenzekelayo, izixhobo zonyango, kunye nezicelo ze-aerospace, apho amaxesha okuphendula ngokukhawuleza (ngokuqhelekileyo <20 ms) achaphazela ngokuthe ngqo ukusebenza kunye nokhuseleko. Eli nqaku liphonononga amacebo anokusetyenzwa ukuze kunyuswe ixesha labo lokuphendula, lixhaswa lulwazi lobugcisa kunye nemizekelo yehlabathi lokwenyani.

1. Lungiselela i-Electromagnetic Coil Design

Ikhoyili ye-solenoid yenza amandla kazibuthe ukuze avule ivalve. Uphuculo oluphambili lubandakanya:

• I-Coil eyandisiweyo iyajika: Ukongeza ii-windings ezininzi zocingo kwandisa i-magnetic flux, ukunciphisa ukulibaziseka kokuvula14.

• Izixhobo zokuxhathisa okuphantsi: Ukusebenzisa ucingo lobhedu olucocekileyo lunciphisa ukulahleka kwamandla kunye nokuveliswa kobushushu, ukuqinisekisa ukusebenza okuzinzile3.

• Ulungelelwaniso lweekhoyili ezimbini: Uphononongo olwenziwe nguJiang et al. kuphunyezwe i-10 ms ixesha lokuphendula (ukusuka kwi-50 ms) kusetyenziswa uyilo olujika kabini, olulungele usetyenziso lwe-aerospace efuna i-action ekhawulezayo kakhulu4.

Into yokuphonononga: Ivalve elungele ukundiza yanciphisa ixesha lokuphendula nge-80% ngokusebenzisa i-coil geometry ephuculweyo kunye nokunciphisa i-inductance4.

2. Cokisa uLwakhiwo lweValve kunye nooMechanics

Uyilo lomatshini luchaphazela ngokuthe ngqo isantya sokuvula:

• IiPlunger eziKhala: Ukunciphisa ubunzima obuhambayo (umzekelo, i-titanium alloys) inciphisa inertia, eyenza ukunyakaza ngokukhawuleza314.

• Precision Spring Tuning: Ukufanisa ukuqina kwentwasahlobo kumandla kazibuthe kuqinisekisa ukuvala ngokukhawuleza ngaphandle kokudlula3.

• Izikhokelo ze-Low-Friction: Imikhono yevalve ekhazimlisiweyo okanye iingubo zekeramic zinciphisa ukuncamathela, zibaluleke kakhulu kwizicelo zomjikelo ophezulu1.

Umzekelo: Iivalvu ze-CKD eziphuculweyo zokuphendula nge-30% zisebenzisa ii-cores ze-tapered valve kunye ne-preload ye-spring preload3.

3. UPhuculo loLawulo oluPhezulu loMqondiso

Iiparamitha zolawulo zinefuthe kakhulu kwimpendulo:

• I-PWM (UkuModelwa koBububanzi bePulse): Ukulungelelanisa imijikelo yomsebenzi kunye namaxesha okulibaziseka kwandisa ukuchaneka kwe-actuation. Uphononongo lwe-2016 lunciphise ixesha lokuphendula kwi-15 ms usebenzisa i-voltage ye-drive ye-12V kunye ne-5% ye-PWM duty8.

• Incopho-kwaye-Bamba iiSekethe: I-pulse yokuqala ye-voltage ephezulu ikhawulezisa ukuvulwa kwevalve, ilandelwa yi-voltage ephantsi yokubamba ukunciphisa ukusetyenziswa kwamandla14.

Indlela eqhutywa yiDatha: Indlela yokusebenza yomgangatho wokusabela (RSM) ichonga amandla ombane afanelekileyo, ukulibaziseka, kunye nomlinganiselo womsebenzi, inciphisa ixesha lokuphendula ngama-40% kwiinkqubo zokutshiza kwezolimo8.

4. UKhetho lweMathiriyeli yokuZinza kunye nesantya

Ukhetho lwezinto eziphathekayo lulungelelanisa isantya kunye nobomi obude:

• Ii-alloys ezixhathisa ukonakala: Insimbi engenasici (316L) okanye izindlu zePEEK zimelana neendaba ezinzima ngaphandle kokuthoba ukusebenza114.

• Ii-cores eziPheleleyo eziphezulu: Izinto ze-Ferromagnetic ezifana ne-permalloy ziphucula ukusebenza kakuhle kwamagnetic, ukunciphisa ixesha lamandla4.

5. ULawulo lweNdawo kunye namandla

Imiba yangaphandle ifuna ukuncitshiswa:

• Ubonelelo lwaMandla oluZinzileyo: Ukuguquguquka kombane>5% kunokulibazisa ukuphendula; iziguquli ezilawulwayo ze-DC-DC ziqinisekisa ukungaguquguquki314.

• Ulawulo lweThermal: Ubushushu bokushisa okanye iikhoyili ezizinzile ngokwe-thermal zithintela ukuchasana nokukhukuliseka kwiindawo ezinobushushu obuphezulu14.

Isicelo soShishino: Umatshini wokupakisha uzuze i-99.9% yexesha lokuphumla ngokudibanisa abaqhubi abahlawulelweyo3.

I-Case Study: I-valve ye-Ultra-Fast kwiZixhobo zoNyango

Umvelisi wesixhobo zonyango unciphise ixesha lokuphendula ukusuka kwi-25 ms ukuya kwi-8 ms ngoku:

1. Ukuphumeza ii-windings ezine-coil ezimbini.

2. Ukusebenzisa i-titanium plunger kunye nezikhokelo zokukhuhlana okuphantsi1.

3. Ukwamkela ulawulo lwe-PWM kunye ne-14V ephezulu yombane8.

Ukuqukumbela

Ukuphuculaivalve ye-solenoid encinciixesha lokuphendula lifuna indlela epheleleyo:

1. Ikhoyili kunye nohlengahlengiso oluphambiliukwenza imagnethi isebenze ngokukhawuleza.

2. Ukulungiswa koomatshiniukunciphisa inertia kunye nengxabano.

3. I-algorithms yokulawula i-Smartnjenge-PWM kunye ne-RSM.

4. Izinto ezomeleleyoukuthembeka phantsi koxinzelelo.

Yeenjineli, ukubeka phambili ezi zicwangciso kuqinisekisa ukuba iivalvu zihlangabezana neemfuno ezingqongqo kwiirobhothi, i-aerospace, kunye neyeza elichanekileyo.
