Product design in the early stages requires a more quantitative process to ensure that the simulation study's outcome will meet expectations. The purpose of this study was to determine whether a manufacturing simulation software package could effectively evaluate and validate the conceptualised blank and tooling to manufacture a sizeable complex-shaped aluminium alloy aircraft panel using die sheet hydroforming. Blank and tool concepts were conceptualised, evaluated, and validated digitally using the forming process conceptualisation cycle. Without the need to trial several blank and tool concepts physically, a significant saving was achieved using a resource-efficient development process. Even without modelling the hyperelastic rubber elements, a successful die sheet hydroformed simulation result was conducted. However, the study showed that a rubber-to-metal friction coefficient must be incorporated appropriately. The study further showed the lack of standard metrology methods in commercial simulation packages to evaluate a simulation result accurately. Simulation metrology is a new area of interest that requires further development. This research contributes to improving the sheet metal forming simulation process and, specifically, die sheet hydroforming process simulation. The study will benefit the aerospace and automotive industry and promote the adoption of digital manufacturing processes. In die vroeë stadiums vereis produkontwerp 'n meer kwantitatiewe proses om seker te maak dat die simulasiestudie se uitkoms aan die verwagtinge voldoen. Die doel van hierdie studie was om vas te stel of 'n simulasiepakket vir vervaardigingsimulasie die stempelplaat-hidrovorming van 'n aluminiumligering vliegtuigpaneel met 'n komplekse vorm doeltreffend kon evalueer en staaf. Die ru-stuk- en persgereedskap konsepte is digitaal gekonseptualiseer, geëvalueer, en gestaaf met behulp van die konseptualiseringsiklus van die vormingsproses. Omdat dit nie nodig was om verskeie ru-stuk- en persgereedskap konsepte fisies te toets nie, is daar beduidend bespaar deur die gebruik van 'n hulpbron-doeltreffende ontwikkelingsproses. Selfs sonder die modellering van die hiperelastiese rubberelemente kon n suksesvolle hidrovormingsimulasie-uitslag behaal word. Die studie het egter getoon dat n rubber-op-metaal-wrywingskoëffisiënt toepaslik geïnkorporeer moet word. Die studie dui op die gebrek aan standaard metrologiemetodes vir die akkurate evaluering van n simulasie-uitslag in kommersiële simulasiepakkette. Simulasie-metrologie is n nuwe belangstellingsgebied wat verder ontwikkel moet word. Die navorsing dra by tot die verbetering van die simulasieproses van plaatmetaalvorming, en spesifiek die simulasie van die stempelplaat-hidrovormingsproses. Die studie is van nut vir die ruimtevaart- en motorbedryf en bevorder die aanvaarding van digitale vervaardigings-prosesse. |
