Mavavu ang'onoang'ono a solenoidndi zinthu zofunika kwambiri mu makina odziyimira pawokha, zida zamankhwala, ndi ntchito zoyendera ndege, komwe nthawi yoyankha mwachangu (nthawi zambiri <20 ms) imakhudza mwachindunji magwiridwe antchito ndi chitetezo. Nkhaniyi ikufotokoza njira zomwe zingagwiritsidwe ntchito kuti ziwongolere nthawi yawo yoyankha, mothandizidwa ndi chidziwitso chaukadaulo ndi zitsanzo zenizeni.

1. Konzani Kapangidwe ka Ma Electromagnetic Coil

Chokolera cha solenoid chimapanga mphamvu ya maginito kuti chiyendetse valavu. Zinthu zofunika kwambiri ndi izi:

• Kutembenuka Kowonjezereka kwa Coil: Kuonjezera ma waya ambiri kumawonjezera mphamvu ya maginito, kuchepetsa kuchedwa kwa kuyatsa14.

• Zipangizo Zosalimba Kwambiri: Kugwiritsa ntchito waya wamkuwa woyeretsedwa kwambiri kumachepetsa kutayika kwa mphamvu komanso kupanga kutentha, zomwe zimapangitsa kuti ntchito ikhale yokhazikika3.

• Makonzedwe a Dual-CoilKafukufuku wochitidwa ndi Jiang et al. adapeza nthawi yoyankha ya 10 ms (kuchokera pa 50 ms) pogwiritsa ntchito kapangidwe ka double-winding, koyenera kugwiritsa ntchito ndege zomwe zimafuna actuation yachangu kwambiri4.

Phunziro la Nkhani: Valavu yokonzeka kuuluka inachepetsa nthawi yoyankhira ndi 80% kudzera mu mawonekedwe abwino a coil ndi kuchepa kwa inductance4.

2. Konzani Kapangidwe ka Vavu ndi Makina

Kapangidwe ka makina kamakhudza mwachindunji liwiro la ntchito:

• Opuntha Opepuka: Kuchepetsa kulemera kosuntha (monga titaniyamu alloys) kumachepetsa kutopa, zomwe zimathandiza kuti kuyenda kuyende mwachangu314.

• Kusintha kwa Masika Molondola: Kugwirizanitsa kuuma kwa kasupe ndi mphamvu ya maginito kumatsimikizira kutsekedwa mwachangu popanda kupitirira muyeso3.

• Malangizo Ochepetsa Mikangano: Ma valavu opukutidwa kapena zokutira za ceramic zimachepetsa kumamatira, zofunika kwambiri pakugwiritsa ntchito nthawi yayitali1.

Chitsanzo: Ma valve a CKD adakweza mayankho ndi 30% pogwiritsa ntchito ma valve cores ochepetsedwa komanso ma spring preload okonzedwa bwino3.

3. Kukonza Zizindikiro Zapamwamba Zowongolera

Magawo olamulira amakhudza kwambiri mayankho:

• PWM (Kusinthasintha kwa Kuchuluka kwa Kugunda): Kusintha nthawi yogwira ntchito ndi nthawi yochedwetsa kumawonjezera kulondola kwa actuation. Kafukufuku wa 2016 adachepetsa nthawi yoyankha kufika pa 15 ms pogwiritsa ntchito voteji ya 12V drive ndi 5% PWM duty8.

• Ma Circuits Ozungulira ndi Ogwira: Ma pulse oyamba okhala ndi mphamvu zambiri amathandizira kutsegula kwa valavu, kutsatiridwa ndi mphamvu yochepetsera mphamvu kuti achepetse kugwiritsa ntchito mphamvu14.

Njira Yoyendetsera DetaNjira yoyankhira pamwamba (RSM) imazindikira kuchuluka kwa magetsi oyenera, kuchedwa, ndi ntchito, zomwe zimafupikitsa nthawi yoyankhira ndi 40% mu njira zopopera zaulimi8.

4. Kusankha Zinthu Zofunika Kuti Zikhale Zolimba komanso Liwiro

Zosankha zakuthupi zimasinthasintha liwiro ndi moyo wautali:

• Ma Aloyi Osagonjetsedwa ndi Dzimbiri: Zitsulo zosapanga dzimbiri (316L) kapena nyumba za PEEK zimapirira zinthu zolimba popanda kuwonongeka kwa ntchito114.

• Ma Cores Okhazikika Kwambiri: Zipangizo za Ferromagnetic monga permalloy zimathandizira kuti maginito azigwira bwino ntchito, kuchepetsa nthawi yopezera mphamvu.

5. Kusamalira Zachilengedwe ndi Mphamvu

Zinthu zakunja zimafuna kuchepetsa:

• Mphamvu YokhazikikaKusinthasintha kwa magetsi >5% kumatha kuchedwetsa kuyankha; ma converter a DC-DC olamulidwa amaonetsetsa kuti magetsi akuyenda bwino314.

• Kusamalira Kutentha: Ma heat sinks kapena ma coil okhazikika pa kutentha amaletsa kusuntha kwa mphamvu m'malo otentha kwambiri14.

Kugwiritsa Ntchito Mafakitale: Makina opakira zinthu adagwira ntchito ndi 99.9% pophatikiza ma driver olipira kutentha3.

Phunziro la Nkhani: Valavu Yothamanga Kwambiri ya Zipangizo Zachipatala

Wopanga zida zachipatala anachepetsa nthawi yoyankha kuchokera pa 25 ms kufika pa 8 ms ndi:

1. Kugwiritsa ntchito ma windings a dual-coil4.

2. Kugwiritsa ntchito titanium plunger ndi malangizo ochepetsa kupsinjika1.

3. Kugwiritsa ntchito ulamuliro wa PWM ndi voteji yapamwamba ya 14V8.

Mapeto

Kukonza bwinovalavu yaying'ono ya solenoidNthawi yoyankhira imafuna njira yonse:

1. Kukonzanso koyilo ndi pakatikuti maginito ayambe kugwira ntchito mwachangu.

2. Kukonza makinakuchepetsa kupsinjika ndi kupsinjika.

3. Ma algorithms anzeru owongoleramonga PWM ndi RSM.

4. Zipangizo zolimbakuti munthu akhale wodalirika ngakhale atakhala ndi nkhawa.

Kwa mainjiniyaKuika patsogolo njira izi kumaonetsetsa kuti ma valve akukwaniritsa zofunikira kwambiri mu robotics, aerospace, ndi mankhwala olondola.
