20.500.12556/RUL-170664 Zasnova počivalnika z lesenim lameliranim nosilcem Design of lounge chair with wooden laminated beam Skonstruirali in izdelali smo prototip počivalnika z enim lameliranim nosilcem. Prototip smo nato testirali po standardu SIST EN 12520:2010 Pohištvo – Trdnost, trajnost in varnost – Zahteve za sedežno pohištvo za domačo uporabo. Zanimalo nas je, koliko se bo povesil ob določeni obremenitvi ter ali bo te obremenitve zdržal. Prototip je prestal vse teste, zato nas je zanimalo, kako bi se obnesel počivalnik, narejen iz drugih materialov. Izbrane vhodne materiale smo testirali z upogibnim testom SIST EN 310:1996 : Lesne plošče – Ugotavljanje upogibne trdnosti in modula elastičnosti, s katerim smo izmerili njihovo upogibno trdnost ter modul elastičnosti. Ko smo imeli te podatke, smo s programom SolidWorks Simulation opravili simulacije obremenitve počivalnika iz različnih materialov. Primerjali smo podatke, dobljene s testiranjem prototipa ter rezultate, dobljene s simulacijami. S tem smo videli, kateri material bi bil najprimernejši za izdelavo. Po testiranju prototipa in opravljenih simulacijah izbranih lesnih materialov smo ugotovili, da počivalnik prenese obremenitev, ter da pri tem ni nevarnosti, da bi prišlo do zloma v kritičnih točkah. We designed and constructed a prototype of a lounge chair with a single laminated support. The prototype was then tested according to the SIST EN 12520:2010 standard Furniture – Strength, durability, and safety – Requirements for domestic seating. We were interested in how much the chair would bend under a specific load and whether it could withstand that load. The prototype passed all the tests, which led us to explore how the lounge chair would perform if made from different materials. The selected input materials were tested using the Bending Test SIST EN 310:1996 Wood-based panels – Determination of modulus of elasticity and bending strength, which allowed us to measure their bending strength and modulus of elasticity. Once we had this data, we used SolidWorks Simulation to simulate the load on the lounge chair made from various materials. We compared the results of the prototype testing with the results from the simulations. This allowed us to determine which material would be most suitable for production. After testing the prototype and conducting simulations with the selected wood materials, we found that the lounge chair can easily withstand the specified load without any risk of failure at critical points. konstruiranje počivalnik simulacije obremenitev preskušanje prototipa constructing lounge chair load simulations prototype testing true false false [L.
