Imiterere y'imitako igaragaza imikorere myiza mu by'ubwubatsi mu ikoranabuhanga rigezweho. Mu gutunganya ibice by'impandeshatu, imitako ikwirakwiza imizigo ku bice bifatanye, bigatuma ibikoresho bigumana umutekano nta gukoresha ibikoresho byinshi.
Muri iki gihe, imitako ishyigikira ibintu byose kuva ku bisenge binini bya sitade kugeza ku bikorwa remezo by'ingenzi by'ibiraro. Uburyo bworoshye bwabyo bw'imiterere y'ikirere bupfuka uburyo bworoshye bwo gukoresha ikoranabuhanga butuma igipimo cy'imbaraga n'uburemere kirushaho kwiyongera. Uko ibidukikije byo mu mijyi bigenda birushaho kuba ingorabahizi, ni ko kwishingikiriza kuri sisitemu z'imitako zikora neza bigenda byiyongera.
Uburyo bwo guhagarara bw'imiterere y'urukuta: Jeometri n'uburyo imizigo ikwirakwizwa
Ihame ry'ibanze ry'umugozi riri muri mpandeshatu. Bitandukanye na poligoni ifite impande enye, mpandeshatu ntishobora guhindura imiterere idahinduye uburebure bw'impande zayo. Ubu buryo buhamye butuma inkingi zishobora kurwanya guhinduka neza. Mu mugozi usanzwe, inkingi zigira ikibazo cyo gucika intege cyangwa gukandamizwa.
Urugero, mu gice cyoroshye cya Pratt, ibice bihagaze bikemura ikibazo cyo gukanda mu gihe ibice bigororotse bigenzura umuvuduko. Abahanga mu by'ubwubatsi bakoresha uburyo bwo guhuza imiyoboro kugira ngo babare imbaraga z'imbere muri buri ihuriro.
Mu gihe cy'imiterere myiza, igishushanyo mbonera cyakozwe nezaicyuma gikozwe mu cyumaishobora kwihanganira uburemere bwayo inshuro nyinshi. Ubu buhanga buturuka ku kuba imigozi igabanya cyane igihe cyo kunama, bigatuma abanyamuryango batwara imbaraga zo mu ruhande rumwe. Ahubwo bibanda ku mbaraga zo mu ruhande rumwe. Ubu buryo bwo kwibandaho butuma ibice bito bigabanuka kandi amafaranga agagabanuka.
Inyinshi mu nganda zikoresha icyuma gikomeye cyane gifite modulus yo guhindagurika hafi ya 200 GPa. Ubu bukomere bwinshi butuma inyubako igumana imiterere yayo mu gihe cy'imitwaro iremereye y'ibidukikije. Abashushanya akenshi bakoresha igishushanyo cya mudasobwa kugira ngo bigane ibintu bibangamira ibidukikije mbere yuko itangira gukora. Ubu buryo bunoze bugabanya imyanda y'ibikoresho hafi 15% ugereranije n'inyubako gakondo y'imitambiko. Binyuze mu kwibanda ku gukurura imitambiko, abahanga bagera ku burebure butari bushoboka iyo imitambiko ikomeye ikora.
Ubwiza bw'ibikoresho by'inyubako za Truss: Icyuma ugereranije na Aluminium
Guhitamo ibikoresho bigena imikorere n'igihe kirekire cy'icyuma. Icyuma gikomeje kuba amahitamo akomeye mu bikorwa bikomeye. Icyuma cya Grade S355, gikunze gukoreshwa mu mishinga mpuzamahanga, gitanga imbaraga za 355 MPa. Kuramba kwacyo bituma kiba cyiza ku biraro no ku nyubako ndende. Ku rundi ruhande, ibyuma bya aluminiyumu birimo kwiyongera mu bikorwa by'igihe gito no mu nyubako z'agateganyo.
Aluminium 6082-T6 itanga imbaraga zo gutanga umusaruro zigera kuri 250 MPa ariko ifite uburemere bwa 66% ugereranije n'icyuma. Imibare igaragaza ko gukoresha aluminiyumu bishobora kugabanya ikiguzi cyo gutwara ibintu ho 40% mu gutunganya ahantu hagenewe ingendo. Nubwo icyuma gitanga ubushobozi bwo kwirinda umuriro no kuramba igihe kirekire, aluminiyumu itanga ubushobozi bwo gutwara ibintu budasanzwe.
Ubudahangarwa bw'inkongi nabwo buratandukanye hagati y'ibi byuma. Ibyuma bya galvanised birwanya ingese mu myaka ibarirwa muri za mirongo, ndetse no mu nkengero z'inyanja. Ariko, aluminiyumu ikora urwego rwa oxide rurinda. Uru rwego rurinda kwangirika cyane kw'imiterere y'inzu nta mavuta menshi asigaye. Abakora ibikoresho bya none bakunze gukoresha ifu kugira ngo bongere ubwiza n'uburinzi.
Ku isoko ririho ubu, ibyuma bigizwe n'ibice bigera kuri 70% by'inganda. Aluminiyumu ni yo yiganje mu myidagaduro no mu imurikagurisha bitewe nuko byoroshye guteranya. Guhitamo ibikoresho bikwiye bikubiyemo kuringaniza ikiguzi cy'ibanze, uburemere bw'ibikoresho, n'igihe cy'ubuzima bw'umushinga.
Impinduka mu miterere: Kuva kuri Warren kugeza ku byuma by'ikirere
Abahanga mu by'ubwubatsi bahitamo ubwoko bw'imitako bashingiye ku bisabwa ku burebure n'intego z'ubwiza. Imitako ya Warren, irangwa n'impandeshatu zingana, igabanya uburebure bw'ibice byose. Ikora neza cyane ku burebure buri hagati ya metero 20 na 100. Ku bice binini kurushaho, nko ku kibuga cy'indege, abashushanya bakoresha amafuremu y'ikirere. Iyi mitako ya 3D ikwirakwiza imizigo mu ngero eshatu aho kuba indege imwe gusa.
Ubushakashatsi bwerekana ko inkingi z'ikirere zigera ku burebure bwa metero 150 mu mishinga minini yihariye. Ubu bushobozi butanga ahantu hanini kandi hafunguye imbere ha hangari n'aho gukorera amakoraniro. Mu buhanga bw'ibiraro, inkingi ya Howe ikoresha ibyuma bihagaze mu gukanda, bikwiranye n'imiterere yihariye y'ibiti biremereye. Porogaramu zigezweho ubu zemerera igishushanyo mbonera. Ubu buryo butanga imiterere myiza y'inkingi zikoresha ibikoresho bike kuri 20% ugereranyije n'imiterere gakondo. Ibi bikoresho bya digitale byemeza ko buri garama y'icyuma igira uruhare mu miterere myiza y'inyubako.
Byongeye kandi, imitako yihariye nka Fink truss itanga ubufasha bwiza ku bisenge byo mu mazu. Buri bwoko bukemura ikibazo cyihariye cya mekanike. Umutako wa Warren ugabanya aho gusudira, ibyo bigabanya ikiguzi cy'abakozi bo mu nganda ho 10%. Hagati aho, K-truss ifasha mu kwirinda guhindagurika mu miterere y'ibiraro birebire cyane. Ubwoko butandukanye bw'imitako butanga igisubizo kuri buri cyerekezo cy'ubwubatsi.
Ingaruka ku bukungu n'uburyo bwo gushyiraho ibikoresho by'inyubako za Truss
Agaciro k'ubukungu k'imigozi ntikagarukira ku kuzigama ibikoresho. Kubera ko ibice bikorerwa mu nganda, abakozi bakorerwa aho hantu baragabanuka cyane. Ubushakashatsi bwerekana ko ibisenge bishingiye ku migozi bishyirwaho vuba ho 30% kurusha sisitemu zisanzwe zo gushyiramo imigozi n'inkingi. Uyu muvuduko ugabanya ikiguzi cy'inkunga ku bahanga mu by'ubwubatsi. Ku isoko mpuzamahanga, imigozi ikoreshwa mu buryo bwa modular yemerera kohereza neza. Igikoresho gisanzwe cya metero 40 gishobora gushyiramo ibice byo ku gisenge cy'ububiko cya metero kare 500 niba cyagenewe kubaka ibyari.
Byongeye kandi, ikiguzi cyo kubungabunga imigozi y'ibyuma bikozwe mu cyuma gikomeza kuba gito. Igihe cyo kuyikoresha gikunze kurenza imyaka 60 nta ngaruka nyinshi zihari. Ubukene ku isi bw'imigozi y'ibyuma bugomba kwiyongeraho 5.5% buri mwaka kugeza mu 2030. Uku kwiyongera gukurikira iterambere ry'inganda mu bihugu biri mu nzira y'amajyambere. Utu turere dukeneye uburyo bwihuse kandi bwizewe bwo kubaka.
Byongeye kandi, agaciro gakomeye k'ibyuma bituma ibyuma biba amahitamo arambye. Mu mpera z'ubuzima bw'inyubako, ba nyirabyo bashobora kongera gukoresha hafi 98% by'icyuma. Uku kuzenguruka gukurura abashoramari bibanda ku ntego z'ibidukikije, imibereho myiza, n'imiyoborere. Inganda zikorerwa hanze y'aho zikorera na zo zinoza igenzura ry'ubuziranenge. Imiterere y'uruganda yemerera igeragezwa rya ultrasound ry'ibikoresho byo gusudira, bigatuma 99.9% by'intsinzi mu kazi. Uku kwizerwa bigabanya gutinda guhenda n'ingaruka z'umutekano mu gihe cy'inyubako.
