Inzira zirimo kwigwa kugirango zigabanye uburemere bwibi biraro, bityo bigabanye umutwaro ku binyabiziga bitwara abantu hamwe nuburyo bwo kugarura ibintu. Ugereranije nikiraro cyicyuma, ibikoresho bikomatanya nabyo bifite ubushobozi bwo kongera ubushobozi bwo kwikorera imitwaro no kongera ubuzima bwa serivisi.
Ikiraro cyambere cya Modular Composite Bridge (AMCB) ni urugero. Seemann Composites LLC (Gulfport, Mississippi, Amerika) na Materials Science LLC (Horsham, PA, Amerika) bakoresha karuboni fibre ikomezwa na epoxy laminates (Ishusho 1). ) Igishushanyo mbonera no kubaka). Ariko, ubushobozi bwo gusana izo nyubako mumurima bwabaye ikibazo kibuza iyemezwa ryibikoresho.
Igishushanyo 1 Ikiraro gikomatanyije, urufunguzo rwibanze rwa infield Advanced Modular Composite Bridge (AMCB) yateguwe kandi yubatswe na Seemann Composites LLC na Materials Science LLC ukoresheje karuboni fibre ikomezwa na epoxy resin ikora. Inkomoko yishusho: Seeman Composites LLC (ibumoso) ningabo za Amerika (iburyo).
Mu mwaka wa 2016, Custom Technologies LLC (Millersville, MD, Amerika) yakiriye inkunga y’ingabo z’Amerika zatewe inkunga n’ubucuruzi buciriritse bushya bwo guhanga udushya (SBIR) Icyiciro cya 1 cyo guteza imbere uburyo bwo gusana bushobora gukorerwa neza ku basirikare. Hashingiwe kuri ubu buryo, icyiciro cya kabiri cyinkunga ya SBIR cyatanzwe muri 2018 kugirango kigaragaze ibikoresho bishya nibikoresho bikoresha ingufu za batiri, kabone niyo patch yaba ikozwe nabashya nta mahugurwa abanza, 90% cyangwa arenga yimiterere irashobora kugarurwa Raw imbaraga. Ibishoboka byikoranabuhanga bigenwa no gukora urukurikirane rwisesengura, guhitamo ibikoresho, gukora ingero zikorwa nogukora imashini, kimwe no gusana bito kandi byuzuye.
Umushakashatsi nyamukuru mu byiciro bibiri bya SBIR ni Michael Bergen, washinze akaba na perezida wa Custom Technologies LLC. Bergen yasezeye muri Carderock yo mu kigo cyitwa Naval Surface Warfare Centre (NSWC) maze akora mu ishami ry’imiterere n’ibikoresho mu gihe cy’imyaka 27, aho yayoboye iterambere n’ikoreshwa ry’ikoranabuhanga rikoreshwa mu mato y'Abanyamerika. Dr. Roger Crane yinjiye muri Custom Technologies mu 2015 nyuma yo gusezera muri Navy muri Amerika mu 2011 kandi amaze imyaka 32 akora. Ubuhanga bwe bwibikoresho birimo ubuhanga bwa tekiniki hamwe na patenti, bikubiyemo ingingo nkibikoresho bishya, ibikoresho bya prototype, uburyo bwo guhuza, ibikoresho byinshi, ibikoresho byubuzima, kugenzura ubuzima, no gusana ibikoresho.
Izi mpuguke zombi zashyizeho uburyo budasanzwe bukoresha ibikoresho byinshi kugira ngo bisane ibyangiritse mu nyubako ya aluminiyumu yo mu rwego rwa Ticonderoga CG-47 yayoboye misile Cruiser 5456. mu gusimbuza ikibaho cya platifomu miliyoni 2 kugeza kuri 4 z'amadolari ”, Bergen. Ati: "Twerekanye rero ko tuzi gusana hanze ya laboratoire no muri serivisi nyayo. Ariko imbogamizi nuko uburyo bwumutungo wa gisirikare bugezweho butagenze neza cyane. Ihitamo rihujwe no gusana duplex [cyane cyane mubice byangiritse Uhambire ikibaho hejuru] cyangwa ukure umutungo muri serivisi kugirango usane urwego rwububiko (D-urwego). Kubera ko hakenewe gusanwa ku rwego rwa D, imitungo myinshi ishyirwa ku ruhande. ”
Yakomeje avuga ko igikenewe ari uburyo bushobora gukorwa n'abasirikare badafite uburambe mu bikoresho bikomatanyije, bakoresheje ibikoresho gusa n'imfashanyigisho. Intego yacu nukugirango inzira yoroshye: soma imfashanyigisho, gusuzuma ibyangiritse no gusana. Ntabwo dushaka kuvanga ibisigazwa byamazi, kuko ibi bisaba gupima neza kugirango tumenye neza. Dukeneye kandi sisitemu idafite imyanda iteje akaga nyuma yo gusana birangiye. Kandi igomba gupakirwa nkigikoresho gishobora koherezwa numuyoboro uhari. ”
Igisubizo kimwe Custom Technologies yerekanye neza nigikoresho cyimukanwa gikoresha epoxy ikomye kugirango ihindure ibice bifatika ukurikije ubunini bwibyangiritse (kugeza kuri santimetero 12). Imyiyerekano yarangiye ku bikoresho bigizwe na santimetero 3 z'ubugari bwa AMCB. Ibikoresho byose hamwe bifite uburebure bwa santimetero 3 z'ibiti bya balsa (ibiro 15 kuri metero kibe y'ubucucike) hamwe n'ibice bibiri bya Vectorply (Phoenix, Arizona, Amerika) C -LT 1100 fibre fibre 0 ° / 90 ° imyenda idoze ya biaxial, igipande kimwe cya C-TLX 1900 fibre ya karubone 0 ° / + 45 ° / -45 ° ibiti bitatu nibice bibiri bya C-LT 1100, byose hamwe bitanu. Crane yagize ati: "Twahisemo ko ibikoresho bizakoresha ibishishwa byateguwe muri laminate ya quasi-isotropic isa na axe nyinshi kugira ngo icyerekezo cy'imyenda kitazaba ikibazo".
Ikibazo gikurikiraho ni matinike ya resin ikoreshwa mugusana laminate. Kugirango wirinde kuvanga resin y'amazi, patch izakoresha prereg. Bergen yabisobanuye agira ati: “Icyakora, izo mbogamizi ni ububiko. Gutezimbere igisubizo kibitse, Custom Technologies yafatanije na Sunrez Corp. (El Cajon, Californiya, USA) mugutezimbere fibre fibre / vinyl ester prepreg ishobora gukoresha urumuri ultraviolet (UV) muminota itandatu gukiza urumuri. Yakoranye kandi na Gougeon Brothers (Bay City, Michigan, USA), itanga igitekerezo cyo gukoresha firime nshya yoroheje.
Ubushakashatsi bwambere bwerekanye ko epoxy resin ari resin ikwiranye na karuboni fibre prregregs-UV-ishobora gukira vinyl ester hamwe na fibre yibirahure ikora neza, ariko ntibishobora gukira munsi ya fibre karubone. Dushingiye kuri firime nshya ya Gougeon Brothers, progaramu yanyuma ya epoxy yakize kumasaha 1 kuri 210 ° F / 99 ° C kandi ifite ubuzima buramba mubushyuhe bwicyumba-ntibikenewe kubika ubushyuhe buke. Bergen yavuze ko niba hakenewe ubushyuhe bwo hejuru bw’ibirahure (Tg), ibisigarira na byo bizakira ku bushyuhe bwo hejuru, nka 350 ° F / 177 ° C. Preregs zombi zitangwa mubikoresho byo gusana byoroshye nkigipande cyibikoresho byateguwe bifunze mu ibahasha ya firime.
Kubera ko ibikoresho byo gusana bishobora kubikwa igihe kirekire, Custom Technologies irasabwa gukora ubushakashatsi bwubuzima. Bergen yagize ati: "Twaguze ibigo bine bikomeye bya pulasitike - ubwoko bwa gisirikare busanzwe bukoreshwa mu bikoresho byo gutwara abantu, kandi dushyira ingero za epoxy adhesive na vinyl ester prereg muri buri kigo." Isanduku yahise ishyirwa ahantu hane hatandukanye kugirango isuzumwe: igisenge cyuruganda rwa Gougeon Brothers i Michigan, igisenge cyikibuga cyindege cya Maryland, ikigo cyo hanze mu kibaya cya Yucca (ubutayu bwa Californiya), na laboratoire yo gupima ruswa hanze mu majyepfo ya Floride. Imanza zose zifite abandika amakuru, Bergen yagize ati: "Dufata amakuru hamwe nicyitegererezo cyo gusuzuma buri mezi atatu. Ubushyuhe ntarengwa bwanditswe mu dusanduku two muri Floride na Kaliforuniya ni 140 ° F, ni byiza ku bisubizo byinshi byo gusana. Ni ikibazo gikomeye. ” Mubyongeyeho, Abavandimwe ba Gougeon bapimye imbere imbere ya epoxy resin nshya. Bergen yagize ati: "Ingero zashyizwe mu ziko kuri 120 ° F mu mezi menshi zitangira gukora polymerize." Ati: "Icyakora, ku ngero zijyanye nazo zabitswe kuri 110 ° F, imiti ya resin yateye imbere gusa ku rugero ruto."
Isanwa ryagenzuwe ku kibaho cy’ibizamini hamwe niyi ngero yerekana urugero rwa AMCB, yakoresheje ibikoresho bya laminate n’ibikoresho nk’ikiraro cyambere cyubatswe na Seemann Composites. Inkomoko yishusho: Custom Technologies LLC
Kugirango werekane tekinike yo gusana, hagomba gukorwa laminate ihagarariye, yangiritse kandi igasanwa. Klein yagize ati: "Mu cyiciro cya mbere cy'umushinga, twabanje gukoresha ibiti bito bito 4 x 48-bine hamwe n'ibizamini bine byunamye kugira ngo dusuzume niba bishoboka ko ibikorwa byacu bisanwa." Yakomeje agira ati: "Hanyuma, twimukiye kuri 12 x 48 ya santimetero mugice cya kabiri cyumushinga, dushyira imizigo kugirango tubyare ibibazo bya biaxial bitera kunanirwa, hanyuma dusuzuma imikorere yo gusana. Mu cyiciro cya kabiri, twasoje kandi icyitegererezo cya AMCB twubatsemo Maintenance. ”
Bergen yavuze ko itsinda ry’ibizamini ryakoreshejwe mu kwerekana imikorere yo gusana ryakozwe hifashishijwe umurongo umwe wa laminates hamwe n’ibikoresho fatizo nka AMCB yakozwe na Seemann Composites, “ariko twagabanije umubyimba w’ikibaho uva kuri santimetero 0.375 ugera kuri santimetero 0.175, dushingiye ku ngingo ibangikanye. . Uku niko bimeze. Uburyo, hamwe nibindi bintu byongeweho bya tewolojiya ya beam hamwe na tewolojiya ya laminate ya kera [CLT], byakoreshejwe muguhuza umwanya wa inertia hamwe no gukomera gukomeye kwa AMCB yuzuye hamwe nibicuruzwa bito byerekana ubunini bworoshye kubyitwaramo nibindi byinshi bidahenze. Hanyuma, twe isesengura ryibintu bitagira ingano [FEA] ryakozwe na XCraft Inc. (Boston, Massachusetts, USA) ryakoreshejwe mu kunoza igishushanyo mbonera cyo gusana amazu. ” Imyenda ya karubone yakoreshejwe mubizamini hamwe na moderi ya AMCB yaguzwe muri Vectorply, naho balsa core yakozwe na Core Composites (Bristol, RI, US) yatanzwe.
Intambwe ya 1.Iki kizamini cyerekana ibipimo bya santimetero 3 kugirango bigereranye ibyangiritse byerekanwe hagati no gusana umuzenguruko. Inkomoko yifoto yintambwe zose: Custom Technologies LLC.
Intambwe ya 2. Koresha amashanyarazi akoreshwa na bateri kugirango ukureho ibintu byangiritse hanyuma uzenguruke icyuma cyo gusana hamwe na tapi 12: 1.
Bergen yabisobanuye agira ati: “Turashaka kwigana ibyangiritse cyane ku kibaho cy’ibizamini kuruta uko bigaragara ku kiraro cy’ikiraro mu murima.” Ati: "Uburyo bwacu rero ni ugukoresha umwobo wabonye gukora umwobo wa santimetero 3. Hanyuma, dukuramo icyuma cyibikoresho byangiritse kandi dukoresha urusyo rwa pneumatike rufite intoki kugira ngo dutunganyirize igitambaro cya 12: 1. ”
Crane yasobanuye ko kugirango fibre fibre / epoxy isanwe, iyo ibikoresho byangiritse "byangiritse" nibimara gukurwaho hanyuma hagashyirwaho igitambaro gikwiye, prereg izacibwa mubugari n'uburebure kugirango ihuze na taper yahantu yangiritse. Ati: "Kubitsinda ryacu ryikizamini, ibi bisaba ibice bine byateguwe kugirango ibikoresho byo gusana bihuze hejuru yumwanya wambere wangiritse. Nyuma yibyo, ibice bitatu bitwikiriye karubone / epoxy prepreg yibanze kuri iki Ku gice cyasanwe. Buri cyiciro gikurikiranye cyagura santimetero 1 ku mpande zose zo hasi, gitanga buhoro buhoro ihererekanyabubasha riva mu “byiza” rikikije ibikoresho bikikije ahasanwe. ” Igihe cyose cyo gukora ibi byo gusana-harimo gutegura ahasanwa, Gukata no gushyira ibikoresho byo gusana no gukoresha uburyo bwo gukiza-amasaha agera kuri 2.5.
Kuri karuboni fibre / epoxy prereg, ahantu ho gusana hapakiye vacuum kandi igakira kuri 210 ° F / 99 ° C kumasaha imwe ukoresheje bateri ikoresha amashanyarazi.
Nubwo gusana karubone / epoxy byoroshye kandi byihuse, itsinda ryabonye ko hakenewe igisubizo cyoroshye cyo kugarura imikorere. Ibi byatumye habaho ubushakashatsi bwa ultraviolet (UV) ikiza preregs. Bergen yabisobanuye agira ati: "Inyungu muri Sunrez vinyl ester resin zishingiye ku bunararibonye bw’amato hamwe n’uwashinze iyi sosiyete Mark Livesay." Ati: "Twabanje guha Sunrez umwenda w'ikirahuri cya kwasi-isotropique, dukoresheje vinyl ester prepreg, hanyuma dusuzuma umurongo ukiza mubihe bitandukanye. Byongeye kandi, kubera ko tuzi ko vinyl ester resin idasa na epoxy resin Itanga imikorere ikwiye ya kabiri, bityo rero hasabwa izindi mbaraga kugirango dusuzume ibintu bitandukanye bifatanyiriza hamwe kandi tumenye imwe ikwiranye no gusaba. ”
Ikindi kibazo nuko fibre yibirahure idashobora gutanga imiterere yubukorikori nka fibre karubone. Crane yagize ati: "Ugereranije na karubone / epoxy patch, iki kibazo gikemurwa hakoreshejwe ikindi kirahure cy'ikirahure / vinyl ester". Ati: “Impamvu ituma hakenerwa urwego rumwe gusa ni uko ibirahuri ari umwenda uremereye.” Ibi bitanga ibishishwa bikwiye bishobora gukoreshwa no guhuzwa muminota itandatu nubwo haba hakonje cyane / ubukonje bwa infield. Gukiza udatanga ubushyuhe. Crane yerekanye ko iki gikorwa cyo gusana gishobora kurangira mu isaha imwe.
Sisitemu zombi zerekanwe kandi zarageragejwe. Kuri buri gusana, ahantu hagomba kwangirika hashyizweho ikimenyetso (intambwe ya 1), irema hamwe nu mwobo wabonye, hanyuma ikurwaho ukoresheje urusyo rukoreshwa na bateri (intambwe ya 2). Noneho gabanya ahantu hasanwe muri taper 12: 1. Sukura hejuru yigitambara ukoresheje pisine ya alcool (intambwe ya 3). Ibikurikira, gabanya ibice byo gusana mubunini runaka, ubishyire hejuru yisuku (intambwe ya 4) hanyuma ubihuze hamwe na roller kugirango ukureho umwuka mwinshi. Kubirahuri bya fibre / UV-ikiza vinyl ester prepreg, hanyuma shyira urwego rwo kurekura ahantu hasanwe hanyuma ukize patch ukoresheje itara rya UV ridafite umugozi muminota itandatu (intambwe ya 5). Kuri karuboni fibre / epoxy prepreg, koresha progaramu yateguwe mbere, buto imwe, amashanyarazi akoreshwa na batiri kugirango bapakire vacuum hanyuma ukize ahantu hasanwe kuri 210 ° F / 99 ° C kumasaha imwe.
Intambwe ya 5. Nyuma yo gushyira igishishwa cyahantu hasanwe, koresha itara rya UV ridafite umugozi kugirango ukize patch muminota 6.
Bergen yagize ati: "Hanyuma twakoze ibizamini kugira ngo dusuzume ifatizo rifatika n'ubushobozi bwaryo bwo kugarura ubushobozi bwo gutwara imizigo." Ati: "Mu cyiciro cya mbere, dukeneye kwerekana uburyo bworoshye bwo gukoresha n'ubushobozi bwo kugarura byibuze 75% by'imbaraga. Ibi bikorwa ningingo enye zunamye kuri 4 x 48 cm ya karuboni fibre / epoxy resin hamwe na balsa core beam nyuma yo gusana ibyangiritse. Yego. Icyiciro cya kabiri cyumushinga cyakoresheje 12 x 48 santimetero, kandi kigomba kwerekana imbaraga zirenga 90% zisabwa imbaraga ziremereye. Twujuje ibyo bisabwa byose, hanyuma dufotora uburyo bwo gusana kuri moderi ya AMCB. Nigute ushobora gukoresha tekinoroji n'ibikoresho kugirango utange icyerekezo. ”
Ikintu cyingenzi cyumushinga nukugaragaza ko abashya bashobora kurangiza byoroshye gusana. Kubera iyo mpamvu, Bergen yagize igitekerezo: “Nasezeranyije ko tuzagaragariza umubano wacu wa tekinike mu ngabo: Dr. Bernard Sia na Ashley Genna. Mu isubiramo ryanyuma ryicyiciro cya mbere cyumushinga, nasabye ko nta gusana. Inararibonye Ashley yakoze gusana. Yifashishije ibikoresho n'imfashanyigisho twatanze, yakoresheje patch arangiza gusana nta kibazo. ”
Igicapo 2 Imashini ikoreshwa na batiri ikiza mbere yateguwe, imashini ikoreshwa nubushyuhe bwa batiri irashobora gukiza karuboni fibre / epoxy yo gusana igikanda kanda buto, bidakenewe ubumenyi bwo gusana cyangwa gukiza progaramu ya cycle. Inkomoko yamashusho: Custom Technologies, LLC
Irindi terambere ryingenzi ni sisitemu yo gukiza ikoreshwa na batiri (Ishusho 2). Bergen yagize ati: "Binyuze mu kubungabunga infield, ufite ingufu za batiri gusa." “Ibikoresho byose bitunganyirizwa mu bikoresho byo gusana twateje imbere ni umugozi.” Ibi birimo amashanyarazi akoreshwa na batiri yakozwe hamwe na Custom Technologies hamwe n’imashini itanga imashini itanga amashanyarazi WichiTech Industries Inc.
