Ama-valve amancane we-solenoididlala indima ebalulekile ezimbonini kusukela ku-aerospace kuya kumishini yezokwelapha, lapho ukulawulwa koketshezi okwesibili kubalulekile. Ukubambezeleka kwesikhathi sabo sokuphendula kungonakalisa ukusebenza kahle kwesistimu, ukunemba, nokuphepha. Lo mhlahlandlela obanzi uhlola amasu aphambili okuthuthukisa ukusebenza kwevalvu ye-solenoid encane, esekelwa izinhlelo zokusebenza zomhlaba wangempela kanye nokuqanjwa kabusha kwemboni.
1. I-Magnetic Circuit Design kanye Nokuthuthukiswa Kwezinto Ezibalulekile
Inhliziyo yanoma iyiphi i-valve ye-solenoid iyisekhethi yayo kazibuthe. Ukuqamba okusha kule ndawo kuthuthukise isivinini sokuphendula. Isibonelo, i-China Aerospace Science and Technology Corporation ithuthukise i-valve ye-cryogenic solenoid engasindi yezinjini eziwuketshezi ze-oxygen-methane, yazuza ukuncipha ngo-20% esikhathini sokuphendula ngokusabalalisa okuguquguqukayo kazibuthe okulungiselelwe. Amasu asemqoka ahlanganisa:
- I-High-Permeability Cores: Ukusebenzisa izinto ezithambile zikazibuthe njengama-alloys e-iron-silicon noma izingxenye ze-powder metallurgy (PM) kuthuthukisa ukugcwaliswa kazibuthe, kunciphisa isikhathi sokunika amandla.
- Izindandatho Zokuzihlukanisa Zizibuthe: Ukubekwa kwamasu okuhlukanisa izindandatho kunciphisa ama-eddy currents, kuthuthukisa ukusabela okuguquguqukayo. Ucwaningo lubonisa ukuthi ukulungisa indawo yokukhala ku-axis engu-z kunganciphisa isikhathi sokuphendula singafika ku-30%.
- I-Ultra-High-Temperature Sintering: Ukushisisa izingxenye ze-PM kuye ku-2500°F ngesikhathi sokukhiqiza kukhulisa usayizi wokusanhlamvu nokungena kukazibuthe, okuholela kumagnetization ngokushesha .
2. Ukuhlelwa Kabusha Kwesakhiwo Kokusebenza Kahle Kwemishini
Ukumelana nemishini kuyibhodlela eliyinhloko ekuphenduleni kwamavalvu. Onjiniyela bacabanga kabusha izakhiwo zama-valve ukuze banqobe lokhu:
- Ama-Actuator Angasindi: Ukushintsha ama-cores ensimbi endabuko nge-titanium noma izinhlanganisela ze-carbon-fiber kunciphisa inertia. Isibonelo, ivalvu yenjini engu-300N LOX-methane izuze izikhathi zokuphendula ezingaphansi kwe-10ms isebenzisa izinto ezingasindi .
- Amasistimu Asentwasahlobo Alungiselelwe: Ukulinganisa ukuqina kwentwasahlobo kuqinisekisa ukuvala ngokushesha ngaphandle kokubeka engcupheni amandla okuvala. Idizayini yesihlalo esitshekile kumavalvu e-cryogenic igcina ukucindezela kokuvala okuphezulu emazingeni okushisa aphansi kuyilapho ivumela ukunyakaza okusheshayo .
- Ukuthuthukiswa Kwendlela Yamanzi: Amashaneli angaphakathi alula kanye nezingubo zokungqubuzana okuphansi (isb, i-PTFE) kunciphisa ukumelana nokugeleza. Ivalvu yokunweba igesi ye-Limaçon ithole ukuthuthukiswa kokuphendula okungu-56–58% ngokunciphisa ukunyakaza koketshezi.
3. I-Advanced Control Electronics ne-Software
Amasistimu okulawula esimanje aguqula amandla e-valve:
- I-PWM Modulation: I-Pulse Width Modulation (PWM) enemisinga ephezulu yokubamba amaza kunciphisa ukusetshenziswa kwamandla ngenkathi kugcinwa ukusebenza okusheshayo. Ucwaningo olusebenzisa i-Response Surface Methodology (RSM) luthole ukuthi ukuthuthukisa amapharamitha e-PWM (isb, i-12V, ukubambezeleka okungu-15ms, umjikelezo womsebenzi ongu-5%) kunganciphisa isikhathi sokuphendula ngo-21.2%.
- I-Dynamic Current Control: Abashayeli abahlakaniphile abafana nesilawuli se-Burkert 8605 balungisa okwamanje ngesikhathi sangempela ukuze banxephezele ukushisisa kwamakhoyili, baqinisekise ukusebenza okufanayo.
- I-Predictive Algorithms: Amamodeli okufunda omshini ahlaziya idatha yomlando ukuze abikezele futhi ahlole ukubambezeleka okubangelwa ukuguga noma izici zemvelo.
4. Ukuphathwa Okushisayo kanye Nokujwayela Imvelo
Amazinga okushisa aphezulu angathinta kakhulu ukusebenza kwama-valve. Izixazululo zifaka:
- I-Cryogenic Insulation: Amavalvu ebanga le-Aerospace asebenzisa ukuvala isikhala somoya kanye nezithiyo ezishisayo ukuze kugcinwe izinga lokushisa lamakhoyili elizinzile phakathi kuka-60°C no-40°C.
- Ukupholisa Okusebenzayo: Amashaneli ama-Microfluidic ahlanganiswe emizimbeni yamavalvu achitha ukushisa, avimbele ukwanda okushisayo okubangela ukubambezeleka.
- Izinto Ezimelana Nokushisa: Izigxivizo zenjoloba ye-Nitrile nezingxenye zensimbi engagqwali zimelana nokuguquguquka ukusuka ku -196°C kuya ku-100°C, okuqinisekisa ukwethembeka ekusetshenzisweni kwe-cryogenic kanye nezinga lokushisa eliphezulu.
5. Ukuhlola kanye Nokuqinisekisa
Ukulinganisa okunembile kubalulekile ekuthuthukiseni. Amazinga omkhakha afana ne-ISO 4400 adinga izikhathi zokuphendula ezingaphansi kuka-10ms kumavalvu asebenza kahle kakhulu. Ukuhlola okubalulekile kuhlanganisa:
- Ukuhlaziywa kwempendulo: Ukulinganisa isikhathi sokufinyelela ku-90% wengcindezi egcwele ngesikhathi sokuvulwa kanye no-10% ngesikhathi sokuvala.
- Ukuhlolwa Kokuphila Konke: Ivalvu engu-300N LOX-methane ithole imijikelezo engu-20,000 yokuchayeka kwe-nitrogen ewuketshezi ukuze kuqinisekiswe ukuqina.
- Ukuhlolwa Kwengcindezi Enamandla: Izinzwa zengcindezi yesivinini esikhulu zithwebula ukusebenza kwesikhathi sangempela ngaphansi kwemithwalo ehlukahlukene.
6. Izicelo Zomhlaba Wangempela
- I-Aerospace: Ama-valve e-cryogenic angasindi anika amandla ukulawulwa kwe-thrust vector kumarokhethi asebenziseka kabusha.
- Izimoto: Izijovo zikaphethiloli ezisebenzisa ama-solenoid alawulwa yi-PWM afinyelela izikhathi zokuphendula ezingaphansi kwe-5ms, athuthukisa ukusebenza kahle kukaphethiloli.
- Amadivayisi Ezokwelapha: Amavalvu amancane kumasistimu okulethwa kwezidakamizwa asebenzisa ama-Hall thruster akhiwe ngokunemba kwesikali se-nanoliter.
Isiphetho
Ukuthuthukisa isikhathi sokuphendula sevalvu ye-solenoid encane kudinga indlela ehlukahlukene, ehlanganisa isayensi yezinto zokwakha, i-electronics, kanye ne-fluid dynamics. Ngokusebenzisa ukuthuthukiswa komjikelezo kazibuthe, ukuhlelwa kabusha kwesakhiwo, nezinhlelo zokulawula ezihlakaniphile, onjiniyela bangafinyelela izikhathi zokuphendula ezingaphansi kwe-10ms kuyilapho beqinisekisa ukwethembeka kuzo zonke izimo ezimbi kakhulu. Njengoba izimboni zidinga izixazululo ezisheshayo nezisebenza kahle kakhudlwana, lezi ntuthuko zizohlala zibalulekile kubunjiniyela bokunemba besizukulwane esilandelayo.
