Abakora bisi bahura ningorabahizi: gushakisha ibice bitari ibyuma byuruganda rwa bisi byujuje imikorere isabwa, umutekano, nibisabwa biramba-nyamara ntibibaho murutonde urwo arirwo rwose. Ntabwo aribisanzwe rusange cyangwa ibyapa byo gushiraho. Nibikoresho byabigenewe byabugenewe-winch center shaft rollers hamwe na T800 cobalt alloy igaragara hejuru, inzu ya valve yumuvuduko wakozwe kuri ± 0.01 mm kwihanganira GD&T, cyangwa fondasiyo ya pompe yatewe muri AMS 5387 cobalt-nikel ivanze kugirango irinde gusiganwa ku magare no kwambara nabi muri sisitemu yo gufata feri ya hydraulic.
Twashyigikiye bisi zirenga 42 za OEM hamwe nabatanga Tier-1 kuva 2015 - kandi umushinga wose watsinze watangiye kimwe: hamwe nigishushanyo cyanditseho "NTIBIGARAGARA" kandi ikibazo ntagitanga gishobora gusubiza: * "Ibi birashobora gukorwa mubyukuri-byizewe, inshuro nyinshi, kandi mugihe cyagenwe?"
Ubushobozi bwibikoresho ntabwo ari ubushake-ni umusingi
Ibice bya bisi bitari bisanzwe birananirana akenshi ntibiterwa no gukora nabi, ariko biturutse kubisubizo bitari byo. Inkunga y'ingoma yacuzwe kuva mubyuma bisanzwe 4140 irashobora kurokoka igeragezwa rya prototype - ariko mugihe cya toni 12 yikurikiranya yumuzigo hamwe no gutera umunyu-spray, iracika kuri radiyo yuzuye. Twabonye ko bibaho. Niyo mpamvu ibyacu ibice bitari ibyuma byuruganda rwa bisi Akazi gatangirana no gutoranya ibikoresho fatizo byemewe - ntabwo ari urwego gusa, ahubwo ubushyuhe bwinshi bukurikirana, guhuza ingano, hamwe no kugenzura ubushyuhe bwa microstructure.
Kubice byambarwa cyane nkibikoresho byuma bitwara imitambiko cyangwa imiyoboro ihagarikwa ya pneumatike, dusubiramo T800 ya cobalt ishingiye kuri alloys cyangwa AMS 5387.Ibi ntabwo byatoranijwe kubwicyubahiro. Batanga ibisubizo byapimwe: 3.2 × birwanya kwambara kurenza 17-4PH bitagira umwanda mugukoresha-kunyerera, gukomera gukomeye hejuru ya 600 ° C mugihe habaye ubushyuhe bwa feri, hamwe no kurwanya ruswa byemewe kuri ASTM B117 mumasaha 1.500+. Icy'ingenzi, dufatanya kwemeza ibintu bifatika hamwe nababitanga - bitanyuze ku rupapuro rwonyine, ahubwo binyuze mu cyiciro cyihariye cyihariye, ingaruka, na raporo y'ibizamini bya ruswa.
Kwishyira hamwe bihagaritse gukuraho drift
Amaduka amwe yohereza hanze, hanyuma imashini, hanyuma isahani, hanyuma ugenzure. Buri handoff itangiza ikosa rya stack-up. Muri bisi ya chassis ya bisi-cyane cyane ihuza ibyuma bya sensor ya ABS cyangwa guhagarika ikirere ECUs - ± 0,05 mm gutandukana bishobora gutera amakosa yibeshya cyangwa umunaniro udashyitse. Ikigo cyacu cyujuje ISO gikora ishoramari, guta umucanga, gutunganya imirongo myinshi ya CNC (5-axis icyarimwe), kuvura ubushyuhe, no kurangiza hejuru yinzu.
Ibi bivuze ko itsinda rimwe rishyiraho ibishushanyo na gahunda yo gusya ku ntebe yanyuma. Bisobanura ko ubugenzuzi bwa CMM bubaho * nyuma ya * guhangayikishwa no kugabanuka - atari mbere - na nyuma yo gusya bwa nyuma. Twagabanije gutandukana kwa geometrike ku kigero cya 68% mu mishinga 112 idasanzwe ya bisi n’ibipimo ngenderwaho-kuko tugenzura urunigi rwose: kugabanuka gukomeye → gutunganya imashini → kugoreka ubushyuhe → ubusugire bwubuso.
Kwemeza imikorere-ntabwo kubahiriza gusa-bitera ikizere cyo gutanga
“Guhuza no gushushanya” birakenewe - ariko ntibihagije. Igice cya bisi kitari gisanzwe kigomba gukora mubidukikije nyacyo: vibrasi yerekana ibintu biva mumihanda, imiyoboro yumuriro hejuru ya aluminiyumu, urusaku rwa electromagnetiki hafi ya bisi ya CAN. Turarenga rero ASME Y14.5. Buri kintu cyose cyingenzi kigizwe na progaramu yihariye yemewe:
- Ikigeragezo cyumutwaro: Winch center shaft rollers yazengurutse 50.000 × kuri torque yagenwe + 20% birenze
- Kwigana ubushyuhe bwumuriro: Inzu yumuvuduko wamazu yakorewe -40 ° C kugeza kuri + 150 ° C mumasegonda 90
- Igenzura rya EMI: Sensor-mounting brackets scanned for field leakage at 2–250 MHz
- Ikarita ya ruswa: Umunyu-spray wapimwe, hanyuma ucamo ibice kugirango ugenzure ubujyakuzimu bwimbitse
Iyi ntabwo ari ikinamico R&D. Nuburyo twirinda kunanirwa kumurima byatwaye abakoresha bisi $ 18,000 + kuri buri kintu mugihe cyo gutaha no gusaba garanti.
Kuki injeniyeri za bisi zihitamo neza kubyoroshye
Abaguzi bamwe bashyira imbere igiciro gito. Abandi bashyira imbere igihe cyihuta cyo kuyobora. Ariko sisitemu yuburambe bwa bisi ya sisitemu-yasimbuye amato yose muri garanti-ishyira imbere guhanura. Bazi ko $ 2.70 bracket yazigamiwe uyumunsi ihinduka $ 42.000 yibutsa ejo niba kudahuza ubushyuhe bwumuriro bitera sensor idahuye.
Niyo mpamvu badusezeranya hakiri kare-murwego rwo gusuzuma GD&T-atari nyuma yo gukata ibikoresho. Dutondekanya ibyago byo gukora mbere yuko ibishushanyo bikonjeshwa: uburebure bwurukuta ruto cyane kuburyo buta umusenyi uhagaze neza, inguni zidahagije kugirango ziveho, cyangwa ibintu bihanganira kwihanganira biherereye aho kugoreka ubushyuhe bizaba byiganje. Ntabwo tuvuga ngo "oya." Turasaba ubundi buryo - nko kuva mubushoramari ukajya muri centrifugal casting kugirango habeho imiyoboro ya shitingi - ishyigikiwe na moderi yo guhindura imikorere ya FEA.
Iwacu ibice bitari ibyuma byuruganda rwa bisi Ibisubizo bifasha abakiriya muri Amerika ya Ruguru, Ubudage, Polonye, na Maleziya - ntabwo ari uko twohereza ku isi yose, ahubwo ni ukubera ko tuvuga ururimi rwabo rwubuhanga: imigambi yimikorere, kumenya uburyo bwo kunanirwa, hamwe ninyandiko zikurikirana kugeza nimero yashonze.
Urebye imbere, icyerekezo nticyerekeza kubisanzwe-bireba ubwenge bwihariye. Amashanyarazi ya bisi yamashanyarazi arasaba uburyo bushya bwo gukonjesha-inzira ya geometrike, feri ishya yongeraho hydraulic valving igoye, kandi ibinyabiziga byigenga bisaba EMI ikingiwe nububiko. Igisekuru kizaza cya ibice bitari ibyuma byuruganda rwa bisi ntizifata gusa. Bazayobora ubushyuhe, bahagarike urusaku, ibimenyetso byinzira, kandi barokoke ubuzima bwimyaka 15. Ibyo bisaba ibirenze gukora imashini. Irasaba ibikoresho neza, kugenzura ibikorwa, hamwe no kwemeza byerekana inshingano zukuri kwisi-ntabwo ari ibitekerezo bya laboratoire. Aho niho hatangiriye neza-kandi aho kwizerwa gukorerwa.
