20.500.12556/RUL-151576 Contribution of various loads to the convex shape of rock wool insulation slabs during production Rock wool insulation slabs are produced in special curing ovens, where molten rock wool fibres coated with binder are compressed between two slat conveyors and blown with hot air for vitrification. Often, the cross-section of the final slabs is slightly convex, which is undesirable. The degree of convexity depends on the deformation of the steel crossbars of the slat conveyors, which are subjected to combined pressure and nonlinear temperature loadings. Due to this complex loading state, it is difficult to determine the contribution of individual load to the total deformation. The main aim of the study was to determine these contributions. Temperature and stress measurements of the crossbars were performed during rock wool production. Upon collecting these measurements, a finite element (FE) model of a crossbar was established for the identification of the pressure loading acting on the crossbars, and finally for determination of their deformations. As a main result of the study, an inverse problem-based methodology for the identification of the deflection of a structure due to unknown temperature and pressure loadings was established and applied on the specific case. The deviations between the deformations of the FE crossbars and the final shape of the rock wool slabs were below 10%, which validates the novel methodology. chain conveyor finite element analysis stone wool response surface optimization design of experiments elevated temperatures inverse problem thermo-mechanical loading non-linear temperature verižni transporterji analiza končnih elementov kamena volna optimizacija z odzivnim površinam načrtovanje eksperimentov povišane temperature inverzni problem termo-mehanska obremenitev nelinearna temperatura true false true Angleški jezik Slovenski jezik Članek v reviji 2023-10-10 09:10:37 2023-10-10 09:10:42 2023-10-11 03:33:50 0000-00-00 00:00:00 2023 0 0 14 str. iss. 19, art. 6596 Vol. 16 2023 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 621.867.1:519.62 1996-1944 10.3390/ma16196596 167710979 Hladnik,_Jerman-Contribution_of_various_loads_to_the_convex_shape_of_rock_wool_insulation_slabs_during_production.pdf Hladnik,_Jerman-Contribution_of_various_loads_to_the_convex_shape_of_rock_wool_insulation_slabs_during_production.pdf 1 AC99B061F2FBADDFFC6EA44D73CEB316 3adbd35a6e8d7f978c7d5f10cce436ae15d987afb0d99591b7a59848aeca9440 5b628b78-673c-11ee-9430-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=176568 https://www.mdpi.com/1996-1944/16/19/6596 1 202eecf0-673c-11ee-9430-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=176567 Fakulteta za strojništvo 0 0 0
