Zeziphi iisayizi zebholiti ye-ankile eyandisiweyo ezilungele ukugcinwa kwenqwelomoya ngokufanelekileyo? 

Unokucinga ukuba ukukhetha i-ankile yokwandisa imigangatho ye-hangar okanye iileyili zezixhobo ziqondile- vele ufanise i-spec yomthwalo, akunjalo? Kodwa kulondolozo lwenqwelomoya, ubungakanani obungalunganga abukho nje ukutyibilika kobunjineli; lukhuseleko olunokuthi lubhalwe. Ndibone abasebenzi bengagqibekanga kwi-3/4 okanye i-1 bolts yokhuseleko olongezelelweyo, bengaqondi ukuba babeka esichengeni i-substrate yekhonkrithi kwii-hangars ezilawulwa ngubushushu. Impendulo yokwenyani ayikho malunga nebholiti enkulu, kodwa eyona ifanelekileyo ukhunde i-anchor bolt kwinkqubo ethile yenqwelomoya oyibambeleyo-nokuba yindawo yokukhwela i-Boeing 737 yokukhwela inqwelo-moya okanye isikhululo esikhaphukhaphu sokulungisa i-A350.

Umbono ongeyiyo ongundoqo: Shear vs. Vibration

Uninzi lweencwadi zogcino zikunika amanani omthwalo omninzi, kodwa abafane bagxininise imithwalo eguqukayo. I-ankile yokumisa i-injini ibona ukungcangcazela okungaguqukiyo, okusezantsi kwe-amplitude ngexesha lotshintsho lweplanti yamandla. A M10 okanye 3/8-intshi I-ankile inokubamba ubunzima obumileyo, kodwa kwiinyanga, iya kusebenza ikhululekile. Sifunde oku ngendlela enzima kwiprojekthi yothotho lweCRJ. Ukuma akuzange kusilele, kodwa ulungelelwaniso lwahamba, lwabangela usuku oluphazamisayo lokuphinda kutshizwe. Yilapho uqaphela ukuba ubungakanani be-bolt kufuneka buphendule ubomi bokukhathala kwenkqubo ye-anchor ngokwayo, kungekhona nje amandla aphezulu.

Ubunzima, izilungiso ezizinzileyo ezifana neqonga lolondolozo oluhambahambayo okanye iyunithi yamandla ephantsi komhlaba (GPU) ukubopha, iidayamitha ezinkulu njenge M16 okanye 5/8-intshi yenza ingqiqo. Ikhonkrithi kwii-hangars ezindala zinokuguquka, nangona kunjalo. Sakhe sagrumba kwinto ebonakala ngathi yi-slab eyomeleleyo kuphela ukubetha isiqwenga esonakeleyo, sibangela i-ankile ye-5/8 ukuba yande ngaphantsi. Kwafuneka unyuke ukuya kwi-3/4 ye-ankile yokuwa ukuze ufumane unxibelelwano olufanelekileyo. Zizo ezi zinto zimangalisayo ezenza umngxuma wokulingwa kwangaphambili kunye nokuhlolwa kungaxoxiswana.

Emva koko kukho umba we-edge distance. Kwiindawo ezixineneyo ze-hangar, udla ngokugrumba kufutshane ne-saw cuts ekhoyo okanye ezinye iintambo ze-ankile. Ibholithi enkulu ifuna izithuba ezininzi. Ndikhetha iqoqo lezithuba ezifanelekileyo M8 okanye 1/4-intshi iiankile phezu kwebholiti enye enkulu xa usebenza kufutshane nencam ze slab. Ukusasazwa komthwalo kungcono, kwaye unciphisa umngcipheko wokuchithwa kwekhonkrithi. Yindlela yotyando ngakumbi.

Izinto eziphathekayo kunye nokusiNgqongileyo: Imiba ethuleyo

Iindawo ezihlala kwindawo yokuxhoma ayingomagumbi acocekileyo. Babona ulwelo olwenziwa ngolwelo olwenziwa ngamanzi, ukutyibilika komkhenkce, kunye nokutshintsha kobushushu obubanzi. Izikhonkwane zensimbi ezingenasici, njenge-316 grade, ziyi-default ye-corrosion resistance, kodwa iimpawu zabo zokwandisa zihluke kwi-zinc-plated carbon steel. I-ankile ye-wedge eyi-1/2 inokufuna ukunzinziswa nzulu kancinci ukuze kuzuzwe amandla okubamba afanayo kwiimeko ezibandayo. Awukwazi ukutshintsha ubungakanani bezinto eziphathekayo.

Sifumana uninzi lweziqhoboshi zethu ezikhethekileyo, kubandakanywa iankile zodidi oluphezulu, kumenzi onjalo I-Sunnian Zitai Festener Fishaner Comment Com.. Bazinze eYongnian, eyona ndawo iphambili yokuvelisa i-fastener e-China, kunye nokufikelela kwabo kuloliwe ophuma kwi-Beijing-Guangzhou Railway kunye ne-expressways kuthetha ukuba banokusingatha iimfuno ezithile, ezihlala zingekho semgangathweni, kwi-hardware yenqanaba lokubhabha. Xa ufuna ibhetshi ye Ii-ankile zemikhono yentsimbi ye-M12 kunye nobude obuthile bomsonto kwipleyiti yesiko lesixhobo, baye bathembeka. Isikali sabo semveliso sithetha ukuba bayaluqonda unyamezelo, nto leyo ibalulekileyo xa i-drill bit yakho iyi-12.5mm kunye nomkhono weankile uyi-12.3mm.

Ukufuma ngomnye umbulali. Kumaziko olondolozo lwaselunxwemeni, siye sabona ukuthotywa kwegalvanic phakathi kweankile kunye nesixhobo. Nokuba ubungakanani obufanelekileyo bebholiti bunokusilela ukuba kusetyenziswe iwasha engalunganga. Ngoku sidibanisa zonke ii-anchor zethu ezifakelweyo kunye ne-dielectric isolator xa sidibanisa isinyithi esahlukileyo, kungakhathaliseki ukuba yi-bolt diameter. Isongezo esincinci esithintela intloko enkulu ngexesha lophicotho lonyaka lweziko.

Imeko kwindawo: I-Composite Workstation Anchoring

Umsebenzi wanamhlanje we-airframe ubandakanya iiphaneli ezinkulu, ezibuthathaka ezidibeneyo. Iibhentshi zokusebenza kunye neefreyimu zokubamba kufuneka ziqine ematyeni kodwa zikwavumela uhlengahlengiso oluncinci. Apha, ii-ankile zedayamitha ezincinci, njenge M6 okanye 1/4-intshi i-ankile zokulahla, ngokwenene ziphezulu. Bavumela igridi exineneyo yamanqaku okunamathisela emgangathweni. Umlenze webhentshi unokuba ne-multi-hole base plate, esinika ukuguquguquka kokubeka kwakhona iyunithi yonke ngokuhambisa nje imilenze kwiihange ezahlukeneyo kwigridi. Oku akunakwenzeka ngeebholiti ezinkulu ezi-3/4.

Inkqubo yokufakela ibaluleke ngakumbi ngeesayizi ezincinci. I-1/4 i-anchor kwi-5/8 ye-drilled hole ayinakuxolela-umngxuma kufuneka uhlambuluke. Sisebenzisa ii-vacuum drills ngokwenkolo kule nto. Naluphi na uthuli olusezantsi luphazamisa ukwandiswa. Ndingathanda ukufaka i-ankile ezilishumi ezigqibeleleyo ze-M6 kunee-M10 ezintathu ezithandabuzekayo.

Isifundo sokusilela: Kuseto lwangaphambili lwesikhululo sokulungisa esihlanganisiweyo se-A320neo, sasebenzisa i-ankile ye-wedge ye-M8 eqhelekileyo kwitafile yokufunxa. Umthwalo we-cyclic ovela kumjikelo wokuvula/uvala umjikelo wempompo udale iharmonic. Emva kweeveki ezimbalwa, enye iankile yatsala nje ngokwaneleyo ukuba iqhawule itywina kunyango olubalulekileyo. Ukulungiswa kwakungeyobholithi enkulu; yayitshintshela ku-a ukusebenza okuphezulu, iankile ekwaziyo ukungcangcazela kubukhulu obufanayo be-M8, eyenzelwe oomatshini. Ubungakanani buhlala bulungile kwiplate yesiseko, kodwa itekhnoloji ye-anchor yatshintsha.

Izixhobo kunye neZixhobo zeNkxaso ezisezantsi (GSE)

Apha kulapho ubona khona olona luhlu lubanzi lobungakanani. Ijekhi ye-hydraulic enamavili inokufuna kuphela i-ankile ze-M10 zokupaka ii-chocks zokupaka, ngelixa i-jack ye-aircraft esisigxina ifuna indawo enkulu, enzulu. M20 okanye 1-intshi inkqubo iankile. Into ephambili yincwadana yomenzi. Bachaza ipateni kunye nobukhulu. Ukutenxa kuyo komisa iziqinisekiso.

Kwimizila yeenjini kunye neereyile zecrane, ihlala imalunga nomthwalo wokucheba. Iibholithi zichetywe kabini, ngoko ke ububanzi bubalulekile. Kutshanje sifake iireyile zenkqubo entsha yokunyusela iinjini zeGE90. I-spec ibize iiankile ze-M24. Ukuwafumana ngobude obufanelekileyo kunye nokucwangciswa kwentloko yayingumsebenzi. Umthengisi ofana neZitai, egxile kubungakanani bokuvelisa kunye nokuthunyelwa ngaphandle, unokuba ngumthombo osebenzayo wezi zinto zininzi, ezicacileyo, ukuqinisekisa ukungaguquguquki okubalulekileyo xa ufaka ii-ankile ezingama-50 ezifanayo kuloliwe omnye.

Isihendo kuku-over-engineer GSE anchoring. Kodwa kukho iindleko-zombini kwi-hardware kunye nakwi-real estate. I-ankile ye-intshi eyi-1 ifuna umngxuma omkhulu. Ukuba ufuna ukuyisusa okanye uyifudusele kwenye indawo, ushiyeke unondoqo wokupakisha. Ngamanye amaxesha, ipateni eyilwe kakuhle yeebholiti ezincinci yenza inkqubo yomgangatho egcinwe kwaye iguquguquke kwixesha elide.

Isigwebo: Yinkqubo, hayi nje ubungakanani

Ngoko ke, yeyiphi isayizi efanelekileyo? Akukho mpendulo enye. Ukulungiswa ngokubanzi kwi-hangar epholileyo, eyomileyo, M10 ukuba 1/2-intshi iiankile ngamahashe okusebenza. Kwi-GSE enzima, engatshintshiyo, utsibela kuyo M16 nangaphezulu. Kwisixhobo sokungcangcazela okanye iindawo zokusebenza ezichanekileyo, ukhetha i-ankile ekhethekileyo kubungakanani obuncinci, njenge-M8.

Ubungakanani obuhle kakhulu bubo obuhlangabezana neemfuno zomthwalo kunye nokhuseleko olufanelekileyo ngelixa uqwalasela indawo ye-hangar, imeko yekhonkrithi, kunye nesidingo sokuguquguquka kwexesha elizayo. Lurhwebo phakathi kwamandla okugqibela kunye nokugcinwa okusebenzayo.

Hlala uvavanya kwindawo engabalulekanga kuqala. Gqoka, ufake, kwaye ugxininise i-ankile ukusuka kwibhetshi enye. Yenza uvavanyo lokutsala ukuba unako. Olo kukhangela izandla lukuxelela ngakumbi malunga ne-substrate yakho ethile kunayo nayiphi na itshati eya kuze ikwenze. Yiyo le nyaniso isisiseko, esizalwe ngokulungisa ezethu iimpazamo, eyalela ukhetho lokugqibela kumyalelo womsebenzi.
