Kugadziriswa kwemuviri kwekuedza kunomiririrwawo nenhamba yemuenzaniso ine zviyero zvakafanana zvejometri. Nokuda kweizvi, purogiramu yenhamba Ansys Mechanical inoshandiswa. Chimiro chepakati chaive geometric mesh ichishandisa SOLID 185 hexagonal elements ine 20 mm mativi egirazi uye SOLID 187 tetrahedral elements ine 3 mm mativi. Kurerutsa modhi, panguva ino yechidzidzo, inofungidzirwa pano kuti acrylate inoshandiswa yakanyatso kuomarara uye yakatetepa, uye inotsanangurwa sechisungo chakasimba pakati pegirazi nepakati zvinhu.
Mishonga inosanganiswa inogadziriswa mumutsara wakatwasuka kunze kwepakati, uye girasi regirazi rinoiswa pasi pekumanikidzwa kwepamusoro kwe 4000 Pa. Kunyange zvazvo geometric nonlinearities yakatorwa mukuenzanisa mukuenzanisa, chete mutsara wezvinhu zvakashandiswa zvakashandiswa panguva ino ye kudzidza. Kunyangwe iyi iri fungidziro yechokwadi yeiyo mutsara elastic mhinduro yegirazi (E = 70,000 MPa), zvinoenderana nedata sheet remugadziri we (viscoelastic) polymeric core material [17], iyo linear kuomarara E = 8245 MPa yakashandiswa mukati. kuongororwa kwazvino kunofanirwa kutariswa zvakanyanya uye kuchadzidzwa mukutsvaga mune ramangwana.
Mibairo yaunzwa pano inoongororwa zvakanyanya kune deformation pamhepo huru inotakura kusvika 4000 Pa (= ˆ 4kN/m2). Nokuda kweizvi, mifananidzo yakanyorwa neDIC nzira yakaenzaniswa nemigumisiro yekufananidza nhamba (FEM) (Fig. 8, pasi kurudyi). Nepo dhizaini yakakwana ye0 mm ine "yakanaka" mutsara inotsigira munharaunda yekumucheto (kureva, mapaneru perimeter) inoverengerwa muFEM, kutamiswa kwepanyama kwenzvimbo yekumucheto kunofanirwa kuverengerwa pakuwongorora DIC. Izvi zvinokonzerwa nekuisa kushivirira uye deformation yebvunzo furemu uye zvisimbiso zvayo. Kuenzanisa, muvhareji wekutama munharaunda yemucheto (dashed white line muFig. 8) yakabviswa kubva pakukwirira kwepamusoro pakati pepaneti. Kutamiswa kwakatemwa neDIC neFEA kunofananidzwa muTable 1 uye kunoratidzwa zvine graphic mukona yekuruboshwe yeFig. 8.
Iwo mana akashandiswa mutoro mazinga emuenzaniso wekuyedza akashandiswa senzvimbo dzekudzora kuongororwa uye kuongororwa muFEM. Iyo yakanyanya kusimuka yepakati peplate inoumbwa munzvimbo isina kutakurwa yakatemwa neDIC kuyerwa pamwero wemutoro we4000 Pa pa2.18 mm. Nepo FEA kutamiswa pamitoro yakaderera (kusvika ku2000 Pa) ichikwanisa kunyatso kuburitsa maitiro ekuyedza, iyo isiri-mutsara yekuwedzera mukunetseka pamitoro yepamusoro haigone kuverengerwa nemazvo.
Nekudaro, zvidzidzo zvakaratidza kuti mapaneru anoumbwa anogona kumirisana nemhepo yakawandisa. Iyo yakakwirira kuomarara kweiyo lightweight panels inomira zvakanyanya. Uchishandisa masvomhu ekuongorora anoenderana nedzidziso yemutsara yeKirchhoff mahwendefa [20], deformation ye2.18 mm pa4000 Pa inowirirana nedeformation yeplate rimwe regirazi 12 mm gobvu pasi pemamiriro akafanana emuganhu. Nekuda kweizvozvo, ukobvu hwegirazi (inove ine simba rakawanda mukugadzirwa) mune ino composite panel inogona kudzikiswa kusvika 2 x 3mm girazi, zvichikonzera kuchengetedza kwezvinhu zve50%. Kuderedza huremu hwese kwepaneti kunopa mamwe mabhenefiti maererano nekusangana. Nepo 30 kg composite panel inogona kubatwa nyore nevanhu vaviri, yechinyakare 50 kg girazi pani inoda rutsigiro rwehunyanzvi kuti ufambe zvakachengeteka. Kuti unyatso kumiririra maitiro emuchina, mamwe mamodheru enhamba anozodiwa muzvidzidzo zvinotevera. Finite element yekuongorora inogona kukwidziridzwa neakawanda akawedzera asiri emutsara emhando mhando dzemapolymers uye adhesive bond modelling.
Kuvandudzwa nekuvandudzwa kwemaitiro edhijitari kunoita basa rakakosha mukuvandudza hupfumi uye kwezvakatipoteredza muindasitiri yekuvaka. Pamusoro pezvo, kushandiswa kwegirazi rakatetepa mumafaçade kunovimbisa simba nekuchengetedza zviwanikwa uye kunovhura mikana mitsva yezvivakwa. Nekudaro, nekuda kwehudiki hudiki hwegirazi, mitsva yekugadzira mhinduro inodiwa kuti isimbise zvakakwana girazi. Naizvozvo, chidzidzo chakapihwa muchinyorwa chino chinoongorora pfungwa yeanosanganiswa mapaneru akagadzirwa kubva mutete girazi uye akasungirirwa akasimbiswa 3D akadhindwa polymer musimboti zvimiro. Iyo yese yekugadzira maitiro kubva padhizaini kusvika pakugadzirwa yakave nedigitized uye otomatiki. Nerubatsiro rweGrasshopper, faira-ku-factory workflow yakagadziridzwa kuti igone kushandiswa kwegirazi rakatetepa rinoumbwa mapaneru mune ramangwana façades.
Kugadzirwa kweyekutanga prototype kwakaratidza kugona uye matambudziko ekugadzira marobhoti. Kunyange kugadzirwa kwekuwedzera nekubvisa kwatove kwakanyatso kusanganiswa, yakazara otomatiki yekunamira application uye kuungana kunyanya kune mamwe matambudziko anofanirwa kugadziriswa mukutsvagisa kunotevera. Kuburikidza nekutanga mechanicha kuyedzwa uye yakabatana neinogumira chinhu chekutsvagisa modhi, zvakaratidzwa kuti huremu uye hutete hwefiberglass mapaneru anopa kuomarara kwakaringana kwekukotama kune yavo yavanoda façade application, kunyangwe pasi pekuremerwa nemhepo. Tsvagiridzo inoenderera mberi yevanyori ichaenderera mberi nekuongorora kugona kweakagadzirwa nedigital girazi rakatetepa rekubatanidza mapaneru ekushandisa kwefaçade uye kuratidza kushanda kwawo.
Vanyori vanoda kutenda vose vatsigiri vane chekuita nebasa retsvakurudzo iri. Kutenda kuEFRE SAB purogiramu yemari yakabhadharwa kubva kuEuropean Union mari nenzira yerubatsiro Nha. 100537005. Pamusoro pezvo, AiF-ZIM yakacherechedzwa kupa mari chirongwa chetsvakiridzo cheGlasfur3D (nhamba yerubatsiro ZF4123725WZ9) tichibatsirana neGlaswerkstätten Glas Ahne, iyo yakapa rutsigiro rwakakura pabasa iri rekutsvagisa. Pakupedzisira, Friedrich Siemens Laboratory nevabatsiri vayo, kunyanya Felix Hegewald uye mubatsiri wevadzidzi Jonathan Holzerr, vanobvuma rubatsiro rwemhizha uye kushandiswa kwekugadzira uye kuedza kwemuviri kwakaumba hwaro hwepepa rino.
